Water Pump: what it does & when to replace it
The water pump circulates coolant through the engine and radiator to keep temperatures in check. Failure signs include coolant leaking from the pump weep hole, a whining or grinding bearing noise, overheating, or coolant pooling at the front of the engine. On many engines the pump is driven by the timing belt, so it is commonly replaced together with the timing belt to save labor. This is an advanced DIY or shop job — access is often deep in the engine and incorrect coolant bleeding can cause overheating.
DIY difficulty: Advanced DIY (often done with timing belt). Always confirm the correct part for your exact build by VIN before buying.
