The most common symptom is a coolant leak from the front-center area of the engine, often appearing as a green, orange, or pink puddle under the car. A failing water pump bearing makes a whining or grinding noise that increases with engine RPM. The engine temperature gauge running higher than normal is another warning sign. Steam from under the hood means the pump has likely already failed and the engine is overheating — pull over immediately. Some water pumps fail gradually (slow leak that gets worse over time) while others fail catastrophically with no warning. If your coolant level keeps dropping without a visible leak, the water pump weep hole may be leaking internally.
On engines with a timing belt (most 4-cylinder engines and some V6s), the water pump is located behind the timing belt cover and is driven by the belt itself. Replacing just the water pump on these engines requires removing the timing belt anyway, which is 80% of the total labor. This is why mechanics strongly recommend bundling the timing belt replacement: you are already paying for the labor to access it. Timing belts have a service interval of 60,000–100,000 miles. If your water pump fails at 70,000 miles and your timing belt is due at 90,000, do both now and save the repeat labor cost in 20,000 miles.
