Signs of a Faulty Water Pump

repair, maintenance, car mechanic, AnnapolisAn engine requires a steady supply of coolant flowing from the radiator into the engine. The vehicle component that has the chief responsibility for this function is the water pump.  A water pump that is working well will help an auto run smoothly at a steady temperature. However, a faulty water pump will eventually result in a failing engine and breakdown. The following will discuss the typical signs of a faulty water pump.

Coolant Leak

Featuring several seals and gaskets, the water pump retains coolant flowing within itself, providing a steady supply of coolant from radiator to engine. As time passes, these seals and gaskets will deteriorate and break eventually, allowing green or red coolant to leak from the water pump and fall to the pavement below. When you notice this leak, it may be wise to tow your car to a service facility instead of driving to avoid overheating.

Loose Water Pump Pulley

Now and then a high-pitched whining will be heard from the engine. The source of this sound is usually a belt that has loosened because the water pump pulley itself has lost its tightness or bearings operating the assembly of the water pump have worn out. Failure of the bearings within the water pump makes the unit impossible to repair, requiring replacement. Once you notice this noise, bring your car in for servicing.

Overheating Engine

A failed water pump will be unable to supply coolant to the engine, causing overheating. The water pump will need to be repaired or replaced immediately. Otherwise, the engine will suffer serious damage such as a blown head gasket, burned pistons, or cracked cylinder head. When the engine temperature gauge is frequently running hot, the cause is probably a faulty water pump. Ask a certified mechanic for an inspection as soon as possible.

Radiator Steam

Steam escaping from the radiator is a sure sign of an overheated engine and perhaps a faulty water pump. Once you notice steam, pull over to the side of the road in a safe and secure area to prevent overheating and a severely damaged engine. Call a tow truck and bring your car to a trusted certified mechanic and have your car inspected.
