The water pump is a critical car part designed to keep the vehicle’s engine at a stable temperature. Although this component can last a decade or longer, there are times when it may fail. To avoid the need for premature engine replacement and other auto repairs, here are three red flags that indicate your car’s water pump isn’t working.

3 Signs of a Failing Water Pump

1. Overheating Engine

When a water pump can’t move coolant, the engine will eventually overheat. You’ll know the coolant isn’t doing its job when the temperature gauge starts climbing. Steam may also come from off the radiator as hot coolant moves through the system.  

If the temperature doesn’t drop, pull over and have the car towed to an auto repair shop. Continuing to drive under these conditions will lead to a complete breakdown that can require engine replacement.

2. Low Coolant Levels

Coolant can leak out from a water pump if its seals or gaskets are cracked or broken. Reduced cooling tank levels and a green or red puddle under the car are indications that there’s a leak.

Low coolant levels will cause the engine to overheat. Depending on the leak’s size, you may be able to refill the coolant temporarily to stabilize the engine until you can get to an auto shop. Small leaks can usually be repaired, but if you ignore the issue, the entire pump may need to be replaced.

3. Harsh Noises

High-pitched squeaking and whining when the engine is running indicate that the water pump needs prompt attention. The volume may also increase when accelerating.

This noise results from a loose belt on the water pump pulley. The belt will loosen if the pulley or the pump’s bearings are worn. If the pulley is the problem, an auto mechanic can repair the situation; however, bad bearings will require a full pump replacement.
