The water pump moves coolant through the engine. A leaking, noisy or failing pump can cause overheating and should be replaced quickly.

Common questions
What are signs of a bad water pump?
Look for coolant drips near the front of the engine, a whine from the pump, or an engine that runs hot. Sweet-smelling steam from under the hood is another sign.
Can I keep driving with a leak?
Only for a very short trip. A leaking pump can empty the coolant fast, and an overheated engine can warp parts that cost thousands to fix.
Why does the cost vary so much?
Some pumps are easy to reach, while others sit behind the timing belt or chain and take hours to get to.
