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.

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.
