How to Tell If Your Car Needs a New Water Pump

Due to a water pump's vital role in cooling your car's engine, there will be immediate consequences if it stops working, including possible engine failure. Replacing a faulty or damaged pump can save you from costly mechanical repairs like replacing your engine. Here, we discuss common signs of a bad water pump and when to get one.

1. Leaking Coolant

A telltale sign of a faulty or failing water pump is a coolant leak that represents itself as a puddle of colored fluid, usually green, orange, or red, under your parked car. We recommend you visit your mechanic as soon as possible while the problem is still relatively minor and easy to fix.

2. High Engine Temperatures

A failing pump will not circulate coolant through your car's engine and other components that need cooling. As a result, these components will overheat or operate at unstable temperatures, exposing your car and yourself to fire hazards.

The chances of serious damage to the engine will be extremely high if it gets too hot. It can damage the cylinders, pistons, and head gaskets, resulting in a potential engine breakdown.

3. Whining Noises

Whenever you hear a high-pitched whining noise coming from the front of your car while accelerating, it could be a sign of pump failure. The water pump needs bearings and pulley belts to function. If one or more of these components are loose or worn out, you will likely hear a harmonic buzzing sound while driving.

4. Steam

In more extreme cases, smoke or steam will come from the radiator or under the hood, indicating an overheating engine that has probably already suffered significant damage. Pull over immediately if you see steam or smoke coming from under your hood and call for help. The most likely culprit will be a faulty or dying water pump.

5. Rust or Deposit Build-Up

Gradual gunk build-up or rust will also be evident if you have a faulty water pump. Rust mainly results from using a defective pressure cap that allows air into your system or a non-compatible coolant. Over time, your pump becomes less efficient, causing complete failure.

Contact a reputable, professional mechanic immediately if you notice any of the signs above. Being proactive in your car maintenance will save you time and money. If you need a new water pump, we invite you to bring your vehicle to Roesbery Car Care Walnut Creek today!
