Located under the timing belt cover, your car's water pump constantly delivers water and coolant to the engine, preventing it from overheating. Although they're relatively durable, water pumps occasionally break down. Sometimes this happens without warning, but in many cases, your water pump will show signs that it's declining before it fails completely.
When you find leaking cooling near the timing belt, it is probably coming right from your car's water pump. Fluids that are yellow, green or red are signs of a leak.
A change in the temperature gauge that occurs suddenly, such as overheating, also signifies a water pump problem. If you're able to move the unit back and forth, the shaft and bearings have likely come loose. When there is an internal failure with the impellers, the pump will still be able to spin, but it will not be able to convey any water to your engine. Auto repair services compare the pump with the impellers on a boat that are malfunctioning when a portion of the propeller has gone missing. There are times when the car will not even start after the water pump has failed.
Given that it takes a lot of labor and time to service the water pump, this is not a good do-it-yourself project. It is far better to have a professional handle these efforts instead, given that the best outcome is usually obtained by replacing the timing belt entirely. Although you do not need to service both of these things at once, doing so just makes sense given where the belt is found. The drive belt can be replaced as well, if necessary, due to the fact that all of these parts are right next to each other.
Several steps are involved in servicing a water pump. First, the auto repair professional tests the cooling system for leaks. Next, the water pump is removed (and replaced if necessary). A new radiator cap is installed, and the system is filled with new coolant. The thermostat may also be replaced.
Water pumps often last just as long as the timing belt which can be anywhere from 60k to 90k miles. Be sure to check your owner's manual to find the specific recommendations that the manufacturer of your vehicle has supplied.
