Common Signs That Indicate a Failing Water PumpSome car parts don't require an immediate replacement, however, the water pump is not among them. The pump plays an integral part in the cooling process of the car's engine and because of that important role, there'll be quick consequences, if it stops working, including possible complete engine failure. It takes time to have your water pump replaced, but it's better to have this type of job on your hands than having a complete engine overhaul. It’s important to know the signs which indicate that there’s something wrong with your water pump.
The main purpose of the water pump is to move coolant through the radiator, as well as around the engine, to misspend heat buildup. Moving fast, these closely-connected metal parts cause a lot of friction, and therefore, heat. The abundance of heat would inevitably damage the structure of the components within the water pump. Usually, the water pump is pulley-driven by the drive belt. There is an impeller that keeps the system circulating, internally.
One revealing sign of a failing water pump is a detectable coolant leak toward the car’s front. If you notice a green or orange puddle on the ground, suspect the water pump.
If there’s a loose accessory belt, this will cause a whining noise, whenever you accelerate. There’s a simple solution for this issue, which includes replacement of the tensioner or tightening of the belt. However, if you hear a growling or grinding noise coming from the engine’s front, that’s a sign of a bad bearing. On the engine’s front, there are several other bearings, but just in case, bring your vehicle to your local mechanic to have a look at it and if needed, to fix it.
The engine will overheat, once the water pump has failed. You should take note of this one, in case you’ve missed all other signs of impending failure. If the “Low Coolant” light is on, add coolant as quickly as possible and look around for a major leak. If the temperature warning light comes on or the temperature gauge rises above normal, pull over and call for roadside assistance.
If you notice steam or smoke coming from your radiator or under the hood, this is an indication that your car’s engine has already suffered plenty of damage. Pull over quickly and call for help. Give the engine a bit of time to cool off before you start looking around because you’re dealing with blistering-hot coolant and other unexpected dangers.
Do yourself a favor and pay attention to the warning signs before it’s too late for your engine. If you notice any of the warning signs, listed above, bring your vehicle to your local auto repair center for a quality water pump service that will save your engine’s life and keep you on the road for as long as possible.
