Hey Duke What is a Good Toyota, Lexus, Scion Car Battery?

We have a significantly strong opinion in support of Interstate batteries, that are produced by the same organization which makes Toyota's batteries, that's Johnson Controls. I've got a strong bias against batteries produced by Exide.

The Toyota batteries produced by Johnson Controls come with an superb history of durability. During the early 1990's Toyota changed over to Exide for a couple of years, and for the first-time that we're aware of they began being required to warranty numerous batteries which were failing in under Twelve months.

They changed back to batteries produced by Johnson Controls, and which I know have not experienced trouble with poor batteries since.Through the 90's we saw exactly the same final results with Exide produced batteries offered under other companies' product labels also. In that period of time, Les Schwab batteries were created by Exide, and again and again we experienced circumstances in which the customer would have trouble "that could not possibly be the battery since it is only 3 months old" that would actually end up being another bad battery produced by Exide.

We Use Interstate Batteries
Batteries tend to be more prone to failure during cold temperature, as due to mixture of the battery being at a reduced level of chemical activity when cold, and also the engine simply being much harder to crank when it's oil is thicker because of being cold. A faltering battery can have numerous signs and symptoms. A gradually faltering batter will steadily turn the engine over slower in the course of start-up. 

Quite often the progression can be so gradual that the main driver does not recognize it simply because each day it's overall performance appears essentially exactly like it did the previous day. A weak battery gets drained of charge considerably more easily as well, so that perhaps only a couple of minutes of sitting with accessories on but the motor off will discharge the battery so you cannot start the vehicle.

When the battery is discharged enough that you no longer get a slow crank from it, quite often the starter will deliver several clicks for a single turn of the key. This occurs for the reason that battery has just enough capacity to engage the starter gear with the engine, but at that time it takes a lot more electrical power than the battery has the capacity to provide, which in turn causes the battery voltage to drop so low that it won't be able to even maintain keeping the starter gear engaged. So, the starter briefly releases, and then when the higher demand is removed, the battery has the capacity to supply enough power to reactivate the starter. This happens repeatedly back-to-back producing multiple clicks for as long as the key is held to the start position.

An alternative cause of the same symptom of multiple clicks in the starter could be poor cable connections from the cables to the battery, which, once again, allow just enough power through to engage the starter, although not enough to keep engagement in the face of the greater demands produced by attempting to crank the engine. From time to time the battery or battery connections will fail at just the right total of failure to permit the starter to give just one click and then hold however, not crank. More frequently the symptom of a single click but no crank implies an issue with the starter, or with the power supply from the key to the solenoid that activates the starter. Occasionally, though, the battery and/or connections can explain the single click.

Is a small leak with my Toyota-Lexus-Scion water pump, a big deal?

Recently I received a telephone call, the person stated that his water pump has a minor leak and was it a problem?

An effectively operating water pump is crucial to your engine's well-being. It circulates coolant through the motor in order to avoid damage from getting too hot. Additionally, it circulates coolant through the heater to supply heat and also to clear the windows of fog or ice. Loss in coolant from a leaking water pump seals could cause overheating and can lead to severe damage to your engine.

In some models a bad water pump bearing can harm the timing belt and make it break or derail. In other models, a worn out bearing makes it possible for the radiator fan to tip forward and cut a hole in the radiator. Any of these developments bring about extra expense and inconvenience to you. Due to the possibility of devastating damage to the engine due to failure, a failing water pump ought to be given high precedence for repair.

How you can determine whether your push ought to be replaced:

  • Let your automobile to sit overnight, parked within a garage having a clean cement floor. If you cannot park it inside over a clean cement surface, place a section of light-colored card board underneath your car or truck directly beneath the motor.
  • Look at card board the next morning. If it appears to be wet from water, you've got a leak someplace, most likely with your water pump or even the gasket. You may notice green fluid on the card board, it's antifreeze. And that means you absolutely have a coolant leak someplace.
  • Look at the water pump pulley. Search for the round section of your water pump the belt is around. Make an effort to push the pulley backward and forward. If it looks loose, it often is time for you to get a new one since the bearing is certainly going bad.
  • Listen to your automobile. Start your car or truck's engine with the cover up. In the event you hear a low-pitched grinding sound, it may be an indication that the bearing is certainly going bad. You'll be able to hear it plainly if it's gone bad.
  • Look for leaks around the water pump and gasket. If you see droplets of water or possibly a small stream, you've got a leak.


Notice in the event the temperature warning light switches on. If your automobile isn't really getting adequate coolant because of a leak or defective waters tube, your automobile engine's temperature will in all probability increase, activating the warning light.

Notice in the event the low coolant light is glowing. This is often a sign that the coolant reservoir is leaking or that you have a bad water pump. An additional alternative is that you have a leak in the coolant system.

Give attention to your car or truck's air conditioner. When your fresh air refresher fail to work effectively, the water pump is probably not doing its job.

Toyota-Lexus-Scion: Axles (front)/CV Joints and Boots

axles-front-cv-joints-and-boots-1
The front axles (and a few rear axles with independent rear suspensions) have flexible joints around the outer and inner ends of your axles allowing your wheels to acquire power efficiently even when going around corners or when proceeding up and down in accordance with the automobile.

A rubber boot encases each one of the joints. This rubber boot is designed to safeguard the constant-velocity joint from losing its grease and from getting damaged by water or road debris.

Ultimately, following flexing through millions of rotations, these boots have a tendency to crack and split open. When this occurs, in the event the axle joint remains to be good, we regularly replace the boots and repack the joints with fresh new grease. So long as the boots are in one piece, the original Toyota joints have a tendency to hold up very well that I prefer replacing the boots to changing your entire axle. Once the boot cracks and splits open, the grease will get flung out also it exposes the joint to the chance of becoming contaminated with water and grit which encourages wear. Even in cases like this, the joint can often be cleaned, relubed, and rebooted when it has not been split open for too much time. On original axles—even with 150k to 200k miles—I would regularly anticipate getting more miles from rebooting the original axle than changing it with an aftermarke one so long as the original axle hasn't gone with out grease.

In the event the joint has become damaged, then the whole axle must be changed. When it is the outer joint that's damaged, it has a tendency to variously produce a cyclic clicking, or knocking, or grinding, or creaking sound when under-going sharp turns. When it is the inner joint that's bad, frequently the symptom will certainly be a heavy vibration experienced on straight line acceleration. If they are available, we've got a strong personal preference for implementing Toyota remanufactured axles. The only part that's being reused is the axle shaft. The joints are new and last as long as the original, which can be much longer than is often expected through the aftermarket axles we have encountered—either new aftermarket or remanufactured. For example, we not too long ago had a customer arrive in with both axles thoroughly symptomatic and badly worn which had been replaced with non-Toyota components at a major tire chain just a year and a half ago. They merely had 26 thousand miles.

As the damage to the axle joint continues, it may ultimately hinder your ability to corner safely and securely. Even though rare, in extraordinary instances it may possibly even break. Once the axle breaks, at minimum the automobile suddenly loses power to the wheels and won't drive. Sometimes it may damage other surrounding parts. A good friend of mine once suffered from an axle break and it also ripped loose his brake lines so that he simultaneously lost the capability either to accelerate or brake. He'd just come down out from the Pyrenees Mountains—off a steep, winding road that ran alongside a cliff's edge—and out on to a level, comparatively safe place to have it happen. Whew! Close call.

Toyota-Lexus-Scion Air Filters: Airflow Fail Sensor

Understanding simply after you ought to replace your air cleaner is difficult since it'd rely principally on what form of driving you are doing and simply what proportion crud your air cleaner ingests. A filter that lasts regarding thirty,000 miles on the vehicle that's for the most part operated on freeways and town streets might last solely some months in an exceedingly country location within which the auto is driven often on gravel or dirt roads.

The engine air cleaner cleans the air that the engine uses for combustion in order that the engine will not get wiped out untimely by having gritty, abrasive air introduced into its internal moving elements.

If it gets too dirty, it restricts the flow into the engine and might cause a loss of power. On older vehicles it will build the engine run considerably richer and with greatly reduced fuel economy.

The signs of a unclean air cleaner vary and might very often have a detectable reduction in ratio. different signs and symptoms square measure potential ignition troubles cause by fouled spark plugs. associate unclean air cleaner inhibits the specified quantity of fresh air from reaching the engine that impacts the emission management systems of the automobile; decreasing air flow and manufacturing manner too made air-fuel mix that may foul the spark plugs. Fouled spark plugs will build a motor miss, rough idle similarly as beginning issues. to boot, a too made fuel mixture can increase engine build up which may even build the Service Engine before long light-weight to return on.

toyota_air_filters-1

We like the quality disposable filters. once Toyota started victimisation the start up vogue mass-airflow sensors to live what proportion air the engine was victimisation, for the primary number of years, it appeared like when we have a tendency to saw a mass-airflow detector fail attributable to fouling, it absolutely was in reference to a K&N air filter-the kind that includes a light-weight oil dressing.

At an equivalent time, we have a tendency to detected that Mazda had determined that victimisation K&N air filters would void the warrant on mass-airflow sensors. Since that point, we have seen many mass-airflow detector failures in vehicles with typical air filters as well; evidentially if you drive enough miles eventually the mass-airflow detector are often fouled with any filter.

But it appears telling to Maine that there was such a delay between the primary failures that we have a tendency to ascertained that were perpetually connected to K&N air filters, and therefore the failures that we have a tendency to eventually began to visualize with the standard filters.

What About Automatic Transmission Flush For My Toyota-Lexus-Scion?

Toyota proper is essentially silent on when you should change the fluid in automatic transmissions under ordinary driving conditions.

They merely convey to examine and advise. We suggest changing your automatic transmission fluid by way of flushing it as being preventative maintenance every 30,000 miles, or sooner in the event the fluid has gone through a substantial colour change that signifies its condition has started to degrade.


get_your_toyota_lexus_scion_transmission_workingThe existing fluid can not be efficiently removed by merely draining. Because of the torque converter not draining, the majority of the fluid remains within the system whether or not the pan is removed.
The best way to accomplish a complete changeover from the transmission fluid would be to flush the entire system. This is very important to the life and health of your vehicle, and much more economic than being required to shell out the thousands required replacing or rebuilding your transmission later on.

The question is from time to time raised whether changing or flushing the transmission can cause any problems, especially when it comes to a vehicle that's long overdue for the fluid change. In more than 16 years of performing this particular service I haven't known any damaging consequence which may remotely be perceived as a result of changing the transmission fluid. I do not remember even any transmission incident that may have been perceived as a regrettable coincidence after changing the material. The approach we take to flush the transmission is actually nothing more than a incredibly thorough fluid change. After draining the pan, we make use of the transmission's own pump to pull in new fluid and push it through the system in the normal direction of flow, pushing out the old fluid ahead of the new. New fluid is pumped through the torque converter and on out from the cooler where we capture it within a drain pan. What could possibly be a more natural or safe way to change your transmission fluid?

Some shops use machines in the flushing procedure that might bring in other issues in to the process compared to what I have described as our procedure. A few of these issues may include special solvents and elevated pressures. Although I hear folks discuss back-flushing, I am not aware of whether any one of the standard procedures essentially involve reversing the fluid flow. I can not say from general observations regardless of whether these alternative procedures raise the potential risk of creating an unintended issue or not.

Signs your vehicle requires a transmission flush: Transmission Grinding or Unusual Sounds, Surging of the Vehicle, Slipping Gears, Trouble Shifting Gears.

Protect Your Toyota, Lexus, & Scion Engine from "The Black Death"

Sludgy deposits in the engine oil usually occur as a result of one or more factors--long intervals between oil changes, and/or insufficient ventilation of the engine crankcase fumes. Once a little sludging occurs, it tends to restrict the vapor flow through the ventilation passages and promotes more rapid sludge build-up along with higher crankcase vapor pressure which results in increased oil consumption, increased oil leakage, and increased likelihood of visible smoke in the exhaust. 

Engine Oil Sludge

If the breathing passages in the valve covers have begun to be restricted, then you can often get a significant benefit from replacing the valve covers. For a number of vehicles, Toyota has come out with redesigned/updated valve covers and PCV (positive crankcase ventilation) valves to counter this tendency to sludge. On vehicles that have plugged up venting passages, we've seen dramatic reductions in oil consumption and visible smoke from oil burning when we've installed the needed new parts. Even when Toyota hasn't updated the covers, if the covers have plugged passages, then the same benefits apply. 

While doing the above repair, you should be aware of the possibility that bits of sludge will be dislodged and migrate down to the oil pan where they can plug up the screen at the oil pick-up tube for the oil pump. If this happens, then the engine pan has to be removed and the pick-up tube/screen assembly has to be replaced.

Regarding the sludge that as accumulated in the engine (other that the sludge in the valve cover breathing passages) once the sludge is in place, I'm not aware of a safe and reliable way to remove it short of performing a complete disassembly of the engine. I'm not comfortable trying to flush it out, as the dislodged sludge is far to likely to end up plugging up the screen at the oil pick-up tube for the oil pump and starve the engine for oil. So, unless you plan on doing an engine overhaul, it seems to me that a "let sleeping dogs lie" policy is the safest course of action with regards to addressing sludge that has already accumulated in the engine. The valve cover replacement mentioned above is intended to reduce oil burning and stop further build-up of sludge.

Is Flushing Your Toyota, Lexus, Scion Brake Fluid Really Necessary ?

You have probably have heard and also been given this recommendation by your auto repair professional. “Your brake fluid is black and needs to be flushed” and you usually decline because you feel that your vehicle is braking and stopping just fine. That may be true, but overtime many factors will begin to affect your braking system.

toyota_brake_fluidThe standard Dot-4 brake hydraulic fluid that Toyota, Lexus, and Scion and most other manufacturers use is hygroscopic-that is to say, it actively absorbs moisture out of the air, which then becomes a corrosive contaminant. Toyota is silent on service intervals for the brake hydraulics, which is odd, because Lexus-their sister company-recommends that it be flushed every 30,000 miles, which seems to be a common (though not universal) industry standard elsewhere as well.

 

The brake fluid starts out clear and almost completely without color. It gets darker and transitions to amber and eventually black with age. In the absence of service records, this serves as a casual indicator of age. Just as a casual aside, the clutch hydraulic fluid, which is identical to the brake fluid, turns black much more quickly than the brake fluid does. I speculate that this is perhaps because of two factors: First, the two systems are each exposed to the air through vent caps with the same sized vents in the reservoir caps. The clutch hydraulic system though has a much smaller amount of fluid in it. As a result, the same total amount of moisture absorbed becomes a much higher percentage of the whole, and so has a greater effect. Secondly, the hydraulic fluid in the brake system is routinely exposed to much higher temperatures, and so has a tendency to cook some of the moisture back out of the fluid. This is just my theory, and I haven't ever seen it discussed anywhere else.

Toyota Parts versus Aftermarket Parts

toyota_genuine_partsToyota makes good parts, and that's what we want to use. Our biggest supplier of parts is a Toyota dealership. Our next biggest supplier is a company that sells us the same parts that were made by the original Toyota parts suppliers.

The result is that the vast majority of the parts we use either come from Toyota direct (through a dealership) or from the original suppliers of the Toyota parts. To give you an example, Nippon makes Toyota's fuel filters.

The Nippon fuel filters look identical to the Toyota filters, and in fact, if we care to peel off the strip of black tape that Nippon has applied to the filters they sell us, underneath the tape is the original Toyota parts sticker with it's Toyota part number.

It's the exact same part whether we buy it from Toyota or from Nippon. Same way with clutches. A company with the name Aisin/Asco makes clutches and water pumps for Toyota.

They used to sell those same parts to us new, in a Toyota box, at a price competitive with the same thing remanufactured from Toyota. There wasn't any question in my mind-I preferred the new to the remanufactured.

Since then, Toyota has prevented them from selling those parts in Toyota packaging, but the parts still have all of the same casting marks and look identical, except the water pumps have had the word "Toyota" ground off and replaced with other company markings.

Again, I have a strong preference for Toyota parts. I've just seen too many poor quality alternatives. As a side note, it's not an uncommon strategy for some aftermarket suppliers to offer a lifetime warranty on their products. This is strictly a marketing tool and usually seems to have no relationship to the quality of their product. Over and over I've met people who have gotten stuck with poor quality parts that repeatedly fail prematurely, and eventually they would get worn out with doing repeat repairs and decide that the better quality Toyota part was the better deal after all. Other times the life-time warranty was handled in such a slippery fashion and it was so difficult to manage their way through the hurdles set before them that the life-time warranty was effectively a lie.

Keep your Toyota Wheels Rolling True - [Alignment/Wheel Alignment ]


You drive your car day after day and you just adapt to how it steers, stops and accelerates. You may say to yourself "wheel alignment" my car drives and so what's the big deal? Why should I care about wheel alignment? Eventually your tire's wear gets to the point that you need to get them replaced. You spend some hard earned dollars and your vehicle gets some news shoes. But what happens when you drive your car for the first time is nothing short of astonishing. Your cars turning ability is sharp and concise, your car accelerates with ease and your car becomes a pleasure to drive. The improved driving is only a small portion of the benefits of having your wheels aligned.

Wheel Alignment Fundamentals

When properly aligned, all four wheels should be pointing together parallel to the centerline of the car if you're driving down the road straight. And, they should be close to perpendicular to the road.

If the wheels are out of alignment, then it causes the tires to wear out more rapidly, it causes the steering to be to be more unstable, and can result in decreased gas mileage. The wheels can get out of alignment by hitting curbs or potholes too hard. They can also get out of alignment due to incremental wear of steering and suspension parts.

Proper Wheel Alignment

 

Benefits of Having Your Wheels Aligned:
1. Less Wear & Tear On Other Parts, Having your wheels out of alignment can be stressful to different parts of your car. A car that's wheels are out of alignment causes a continually need to put pressure on the steering system in order to keep the car straight, and when you brake you often feel the car pulling sharply to one side or the other, causing the brakes to work harder on one side than the other and wearing them unevenly.
2. Better Gas Mileage, with the price of a gallon of gas getting close to $4 per gallon, getting more miles to gallon has become paramount. Proper wheel alignment cuts down on rolling resistance, which means that your car doesn't have to work as hard or burn as much fuel in order to move forward.
3. More mileage from your tires, even the slightest out of alignment can have destructive effects upon your tires. If your tires have too much or too little toe-in (the degree at which they point in toward each other at the front, a narrow strip on each tire will begin to wear down very quickly, causing you to have to get new tires sooner. By getting regular wheel alignments, you ensure that your tires wear evenly, making them last as long as possible.
4. Protects Your Tires Warranty, having your tires have excessive wearing from poor wheel alignment is that it usually voids your warranty on the tires. Most warranties only apply to the quality of the goods. If your tires wear out too soon because of something other than poor quality, then the manufacturer is not responsible. The tire manufacture will site negligence by the car's owner and void the warranty.

Toyota Owners: What Your Check Engine Light Is Trying To Tell You

Check Engine Soon Warning

The check engine light solely comes on once the vehicle’s computer believes there is an actual problem. 

The computer can provide a bother code that indicates either the condition that led to the code (like "Lean condition") or the system that it believes to be functioning incorrectly (like "EGR flow insufficient").

Whether your vehicle may be a Toyota, Lexus or Scion, the very first thing you ought to do is check for a significant problem that needs immediate attention.

 

Check your dashboard gauges and lights for indications of low oil pressure or your temperature gauge shows your engine is really overheating, either of which might need you to immediately pull your vehicle over and shut off the engine. On some cars, a yellow check engine light-weight means that you ought to investigate the matter, whereas a red or blinking check engine light-weight means that you need to stop immediately.

Sometimes the failing system may be electrical in nature that will provide a code like "Open or short in coolant temperature sensing circuit," within which case, there is probably a circuit issue either within the temperature sensing element itself, or the wiring between it and the vehicles computer.

Some failures will not be in any of the items listed above, however, they are usually the result of poor power connection or poor ground that is providing the power to the vehicles computer that controls its ability to diagnose properly. In any case, regardless of what, the issue/warning code is it must be diagnosed. it isn't uncommon for individuals to believe that their car by having a computer completely eliminates the necessity for physically checking the vehicle.

A computer indeed is a marvelous tool that aids the car owner in quickly understanding a problem. It's helpful enough that we've invested a lot of time, effort and thousands of dollars in choosing the best computer and all that goes into keeping them updated, however, the fact remains that a computer is still simply a tool; it isn't magic, and it does not recognize everything. We are heavily dependent on the technician's experience, and judgment. Because of the complexness of the vehicle's system.

During that diagnostic time, we are going to do what will be best to help your vehicle needs. Once we have diagnosed the issue, it will go 3 ways. Best case situation, we have a quick and concise diagnosis of your vehicles issue and repair it.

Next best, and actually quite common, we have diagnosed your Toyota and will leave the decision to repair up to you, equipping you with the information of our diagnosis in the form of a quote for the repair. At that time, you'll be able to say affirmative or no.

Worst case and this very unusual we have reached the end of agreed-upon diagnosis time and that we still haven't been able to ascertain the reason behind the problem. As we have stated before this worst case situation is quite uncommon, however, it is a real possibility.

People usually ask if we charge for diagnostic time. The answer is affirmative. The additional question that is often raised is if we also charge for a diagnostic time if they agree to do the service or repair. The response to that question is that to the extent that the diagnostic efforts and the repair efforts overlap, the client gets the benefit of that overlap. To the extent that diagnostic efforts and therefore the repairs are separate, they're going to be charged for on an individual basis. So, for instance: If we've got to dismantle one thing so as to inform you that it's defective, then we have a tendency to might already be halfway through the labor needed for replacement, and in fact, you will get the best part of this situation. But, if we have performed a diagnose on a part that does not need to be disassembled, then the repair is a completely different activity which would be billed on top of the diagnostic time.
