Symptoms of a Failing Water Pump in Your Car

That pump, hiding under the hood, keeps your car running efficiently, guaranteeing you a safe, comfortable ride. Your vehicle's engine comprises various components that are constantly moving, thereby generating an incredible amount of friction and heat. The water pump moves water (coolant) from the radiator and supplies it through the engine system keeping everything at optimum temperature.

When your water pump is failing, your engine will overheat, causing damage to the cylinder heads, gaskets, and pistons. Much too often, this results in irreversible engine damage and failure. Fortunately, your vehicle's water pump will alert you when it is failing through various telltales

Here are some of the signs to look out for:

A Leaking Coolant

Your car's water pump is made of numerous seals and gadgets to facilitate a smooth, consistent flow of the coolant from the radiator to the engine block, via the thermostat, and back to the radiator. With time, these seals and gadgets loosen up, wear out, break and crack, allowing the coolant to leak from the system to the ground. If you notice a green (or sometimes red) coolant on the ground where you had packed your car, SUV, or truck, be sure to contact your mechanic for a full inspection and repair.

Rust and Deposit Buildup

Over time, the constant leakage leads to the gradual build-up of sludge, scale, and rust on the water pump. Mostly, this happens when drivers and car owners use non-compatible coolant or when the pressure cup is faulty, allowing air into the system. Ultimately, parts of the pump develop holes or cavitation due to corrosion. Within no time, the pump becomes less effective, leading to engine failure.

Noise

Do you hear annoying whining noises when you accelerate? Well, this could be an alert for a loose accessory belt. Does the sound emanate from the engine? You might want to consider dropping your car by an auto repair shop for an inspection to avoid nasty surprises from faulty water pumps.
