Signs of a Failing or Bad Water Pump

If you want to ensure your vehicle stays cool on the hottest summer days, you need to ensure your engine has a constant supply of coolant coming from the radiator and being sent through the entire engine. When the water-cooled engine (other than the air-cooled option) was first introduced, some experts believed the water pump circulating the coolant through the engine block was just as crucial to engine protection as the oil. This is true, even as technology has changed over the years.

The water pump is a crucial component in making sure the engine works properly. This is an impeller pump and is typically found under your engine’s timing belt cover. The pump moves along with the engine’s drive belt – as the belt keeps turning, the pump rotates.

 Like any other mechanical device, there are a few warning signs that the water pump may be wearing. Getting to know these signs will help ensure you know when it is time to go to the mechanic.

Coolant Leak Near the Front of Your Vehicle

Your water pump is made up of several seals and gaskets that keep the coolant contained and made sure there is a consistent flow of coolant coming from the radiator and to the engine. Eventually, these seals and gaskets will crack, dry up, wear out, or completely break. If this happens, coolant may begin to leak and will be seen on the ground.

Whining Sounds

Eventually, you may begin to hear a high-pitched sound coming from the front portion of your motor. The most common cause of this is a loose belt. This is usually caused by pulleys that are loose or that the bearings that are operating the water pump assembly are beginning to wear out. When this happens, repairs may not be possible, and replacement will be needed.

The Engine Is Overheating

If your water pump fails completely, then it won’t be able to properly circulate the needed coolant through the engine block. This can cause the engine to overheat if you do not repair or replace the part right away. If the problem persists, it may damage the cylinder heads, head gaskets, or pistons. Be sure to contact a mechanic as soon as you notice this issue.

If you believe that your water pump is on its last legs, it is time to get your car to a mechanic. While replacing the water pump may be annoying, it is much more affordable than having to get an entirely new engine. Be sure to keep this in mind and take action when necessary before more serious issues arise with the vehicle.
