The ANTIFREEZE Mystery Revealed


ANTIFREEZE: So MANY choices; so little time...

What types of ANTIFREEZE does Integrity Auto recommend for Toyota/Lexus/Scion?

Different types of coolant: Red-colored, pink or green? 

  • The quick response:The best, most uncomplicated recommendation we can make is to use Toyota's red, Long Life Coolant wherever specified, and their pink Super Long Life Coolant where it's specified. On vehicles older than 1998, Toyota's suggestions are very general. However, we are strongly tilted toward Toyota Long Life Coolant for older vehicles as well, because our experience is that the generic coolants are far more likely to clog radiators and heater core coolant passages.
  • The lengthier response:Regarding the frequently used generic, green coolant, we are willing to use it to top off systems that have already have green coolant. However, if we're replacing the coolant, I strongly prefer to go with the appropriate coolant from Toyota. These coolants were specifically formulated with full engineering knowledge of the numerous materials (seals and alloyed metals) they need to protect. They were also intentionally formulated with zero silicates. Although the silicates in other coolants provide exceptional corrosion protection, in the long run, they tend to precipitate out and clog cooling passages. This can eventually result in overheating and/or having to replace the radiator. The additional cost of Toyota's coolant is minimal if you consider that the cost is amortized over a two to three year period and that the superior coolant may well save having to replace your radiator.

If you have ever taken a stroll into your local auto parts store you may have noticed the antifreeze/coolant section has grown substantially. I was recently with a friend and we were in a local auto parts store and he saw that there was over 30 different types or variations of ANTIFREEZE. Of course, there was the store's name brand – (It was also the lowest in price). Then there was the big manufacturers: Prestone, PEAK, Motorcraft, Shell, Mopar, Zerex, etc. There, of course, was the different Antifreeze types: original equipment, precision blend, 50/50, long life, full strength, premix heavy duty formula, conventional full strength formula and on top of all these types were also different colored variations.

Why Were All These Different Types Of ANTIFREEZE Created?

Over the decades, there have been numerous engineering changes in manufacturing materials -- metallurgy, plastics, etc. -- to meet increased fuel economy requirements and longer service intervals. Antifreeze has had to change also, both in order to achieve high quality protection over the longer service intervals and for compatibility with newer manufacturing materials in engines and their cooling systems. Numerous manufacturers are specifying their particular form of antifreeze and with all the aftermarket alternatives available it has become be rather puzzling to the consumer regarding which color or formula of coolant is appropriate for his or her vehicle.

European and Asian coolants are designed to satisfy manufacturer’s specified additives each engine calls for to help keep it operating at its maximum. European and Asian specifications may be greatly different from those created for American vehicles.

Why all the different colors?

The unparalleled growth of the number of available antifreeze/coolant formulations available today has forced antifreeze manufacturers to use different color dyes for different types of antifreeze/coolants. Let's dig into the technical aspects of The ANTIFREEZE MYSTERY. There are three main types of ANTIFREEZE: Inorganic AcidOrganic Acid, and Hybrid Organic Acid.

Inorganic Acid Technology (IAT) This is the prevalent green stuff original equipment companies have utilized for more than 70 years. Ethylene glycol is its basic chemical compound and you will find silicate and phosphate additives which make it appropriate for copper, brass, cast iron, and aluminum cooling system components. Manufacturers recommended that you simply replace the green IAT antifreeze each and every 36,000 miles or 3 years. IAT coolant was utilized in General motors automobiles right up until 1994. Chrysler utilized green IAT material right up until 2001 as did Ford, (excluding some 1999 models that utilized OAT blue coolant which has to be bought from Ford).

Organic Acid Technology (OAT) This coolant is usually dyed Red or yellow. This has no nitrite included. These coolants generally deliver six-hundred thousand miles or 12-thousand engine hours of service life, however, their overall performance life could be significantly decreased if contaminated with nitrite-containing coolants.

Hybrid Organic Acid Technology (HOAT) One version is dyed orange and possesses 10% recycled antifreeze. An additional variation is dyed yellow and doesn't include any recycled antifreeze. This is really a blend of a number of the inhibitors utilized in inorganic IAT and organic OAT coolants, it's generally using a low-silicate, nitrite technologies. As opposed to the OAT and NOAT Extended Life Coolants (ELC), HOAT coolants, such as the IAT coolants, usually require SCA included into the system for the initial routine maintenance span (25,000 miles) or as laid out in the engine maker. HOAT coolants are most frequently identified colored yellow or orange. These formulations aren't suitable for the extended interval coolant formula of both NOAT or OAT coolants and shouldn't be combined with them.

How bad can my engine oil leak really be?




So your automobile is leaking a modest amount of oil. How big of a deal is that? Take a drive to the closest apartment complex you will notice oil spots in almost each and every parking spot. If everyone’s vehicle leaks oil, it mustn't be an issue-right? Perhaps, but the price of driving with your car with very low oil levels and damaging your engine is substantial in comparison to the price of fixing the oil leaks.

Leak location should also be a concern for even small gradual leaks. For instance, a leak inside your valve cover gasket makes it possible for oil to drip on to your exhaust manifold which happens to be so hot it will create nasty smelling smoke and possibly a fire, which makes it an extremely hazardous leak. Oil from seeping seals and gaskets has a tendency to move down, as a result of gravity, and towards the rear of the engine, because of the air movement past the motor.

Engine leaks occur exactly the same way as tranny leaks. The motor housing is a number of components attached to one another. Between these motor housing parts, you will find gaskets, to help sustain a seal. When these gaskets fail, motor oil will leak out. Nevertheless, in contrast to transmission oil that leaks when the automobile is cold, motor oil leakages have a tendency to occur once the motor is hot. It's because of the pressure within the working motor, which in turn causes the oil to get very thin. Motor oil may also leak from your hoses and lines that pump the oil into the motor and drain it out. This is often because of bad clamps or  small breaks or cracks in your hoses.

Oil leaks are often an indication of an automobile problem which will get even worse with time. When the leak is a result of a gasket failing, the oil will ultimately drip out.  An engine leak allows oil to seep out onto a hot motor. This could result in a fire. Additionally, if the motor oil leaks out to the street, sufficient leakage will deplete the motor oil level and the motor could seize upon account of insufficient lubrication.

Due to this, it isn't uncommon that almost everything underneath a leaking seal will probably be wet, and even though you are aware that the leak towards the top and/or front of the motor is leaking, everything beneath it or behind it might or might not be leaking. Frequently the one thing that can be stated without a doubt concerning the other wet areas is that they are in fact wet. Because of this, we advise repairing the recognized leaks, after which cleaning the motor to create a clean slate.

Following this, come back in for another examination following the automobile has been driven long enough for any leak to show itself, although not so prolonged that almost everything could possibly be so broadly wet as to obscure the origin of the leak.

Wheel Bearings and their importance to your safety

Wheel bearings perform a big role within the drivetrain of your automobile as a result of their role they provide the primary link between the moving and static regions of the vehicle. A control – within the most elementary type – is admittedly a friction reduction device positioned inside one thing like a wheel to help the effectiveness of rotation. this can be accomplished as rolling creates considerably less friction force than slidding.

A vehicle's wheel bearing performs this by utilizing small metal balls, these balls that appear between 2 circular rings of metal. beside grease, the bearing moves in-tandem whereas to facilitate the wheel’s turning, the rolling motion of the balls creating its potential for the wheel hub to show as unhampered as potential.

toyota_axel_wheel_bearingsThe wheel bearing is found within the hub assemblage, providing the static reference to the hub’s component in association to the outer ring or racer. The rotating shaft moves from your transmission and goes through the middle of the wheel bearing with the inner ring, permitting the spinning partnership. Roller bearings are used generally on the powered/drive wheels of your vehicle, whereas tapered bearings are primarily used on the non-powered/driven wheels.

This often causes the tone to change, which is able to facilitate in determining whether or not the sound is really associated shaft bearing or a different location, and should (although not always) reveal which side of the vehicle the unhealthy bearing is located at. On rear wheel drive vehicles, often the sound of a nasty rear wheel bearing can most likely be dampened when the driver is braking.

On rear wheel drive vehicles having a solid shaft housing, a nasty shaft bearing can ultimately cause differential oil to leak on the far side the shaft seal and foul the braking system shoes, which implies that the brakes should get replaced as soon as possible. If your rear shaft bearing ought to also become unhealthy enough, it could cause the braking system’s drum locked in connection to the brake shoes and destroying them with extreme heat resulting in braking system failure.

 Front axle/shaft bearings create the ability for the wheel to move over a little bit in order that it's ceaselessly rubbing up against the brakes and unfortunately cause it too destroys the brake caliper and ends up in a complete breakdown of the brake system.

On front-wheel-drive vehicles, often the rolling portion of the bearings will continue you to be in good working order, however during which the inner bearing race presses into the wheel hub might presumably get worn and loose, causing extra play within the wheel. This additional play will cause the rotors to continue on the pads and cause great harm to the brakes owing to the excessive heat created. This issue tends to run undetected. However most times, it creates a very unpleasant squeaking sound.

To be able to scale back the expense of any of these vehicle repairs, it's best to take care of them sooner instead of later. Remaining unrepaired, unhealthy axle/shaft bearings can ultimately harm connected parts that are essential to your safety.

Do you really need to change your oil every 3000 Miles?



Yes and No, it really depends on the age of your vehicle, according to Toyota proper they say Standard Oil Change Intervals. A great guideline with regards to regular oil change time intervals is — every 5,000 miles or twice yearly concerning planned oil changes. Following this guideline helps keep your motor properly lubricated and running efficiently, making certain your 2016 Toyota and more recent makes/models will hold optimum efficiency.

In years past it absolutely was best if you change the oil and filtering regularly, but due to the fact of improvements in engine components and tighter specifications, along with the oil which goes into engines that changed.

Makers recommend you change oil more frequently for "extreme" operating conditions, for example repeated trailer towing, considerable stop-go driving or idling in traffic, (like when traveling the I5 or the 205 in Portland), driving in extreme cold or heat, or frequent short-distance driving where the motor does not achieve full operating temperatures.

Consistently changing your Toyota's engine oil is among the very least glamorous, but a majority of helpful things you can do to make sure your automobile has a lengthy and happy life.

Probably the most essential factors oil ought to be changed is the fact that, as time passes, oil breaks down because of use and heat exposure. It will become less efficient at lubrication, which in turn causes engine components to rub against each other.

Take care of your engine with our Toyota Oil services.

Motor oil also will get contaminated by elements like airborne dirt and dust, metallic particles as well as antifreeze. And are you aware that the additive package, which belongs to your fully designed motor oil, will breakdown over time and turn into a contaminant, as well? As contaminants are pulled in to the oil, sludge is created. This sludge will adhere to areas of the engine resulting in the engine to perform much less effectively. Ultimately, this sludge could cause engine failure.

Main point here changing your engine is a lot more costly than changing your Toyota's oil. Our professional recommendation would be to replace your motor essential oil and filter every 3000+ miles. When performing this service, we also inspect it for any other needs that may have developed in the interim.

Keep Your Toyota's Engine Running Smooth, Oil Change Every 3K!!

Faithfully changing your Toyota's engine oil is one of the least glamorous, but most effective steps you can take to insure that your car has a long and happy life.

One of the most important reasons oil needs to be changed is that, over time, oil breaks down due to use and exposure to heat. It becomes less effective at lubricating, which causes engine parts to rub against one another.

Maintain your engine with our Toyota Oil service.


Motor oil also gets contaminated by substances like dust, metallic shavings and even antifreeze. And did you know that the additive package, which is part of your fully formulated motor oil, will break down in time and become a contaminant, too? As contaminants are whipped into the oil, sludge is formed. This sludge will stick to parts of the engine causing the engine to perform less efficiently.  Eventually, this sludge can cause engine failure.

Bottom line replacing your engine is much more expensive than changing your Toyota's oil.

Our recommendation is to replace your engine oil and filter every 3000 miles. When performing this service, we also inspect it for any other needs that may have developed in the interim.
