What is a water pump?
The water pump is an accessory that assists in keeping your motor cool, typically located on the front of the engine. Coolant needs to cycle through the engine to keep it at an optimum temperature, and the water pump is a vital component of that process. With help from the timing belt or the drive belt (like a serpentine belt), the water pump uses an impeller to push engine coolant through the engine block and cylinder head to the radiator. In the radiator, the coolant is cooled to a lower temperature in the radiator, then the pump pushes the coolant back out to the motor, and this cycle repeats as you operate your vehicle, keeping the coolant circulating through your vehicle.
When should I replace the water pump in my car?
You should take your car to a mechanic to inspect the water pump if you notice any of the following warning signs:
Coolant leaks from the weep hole: The weep hole is a small opening located at the bottom of your water pump, and coolant leaking from the weep hole could indicate a faulty water pump.
Grinding or rough noises: If you hear a low grinding noise while your engine is running, it could be coming from your water pump. These noises signal that the pump’s internal mechanisms have worn out and it’s time for a replacement.
A lit temperature warning light
: When this light goes on, the temperature of your coolant is too high and the engine is likely too hot—which could signal an issue with your water pump.
How often should a water pump be replaced?
Water pumps should generally be replaced every 60,000 to 100,000 miles. However, it’s best to check your owner’s manual or consult your mechanic since the age or mileage limit can differ depending on your vehicle.
Can I replace my water pump myself?
You can complete a water pump replacement at home if you’ve got experience with DIY auto repair, but the replacement will call for knowledge of your vehicle’s engine and the removal of various parts. In most cases, a professional is better equipped to replace your vehicle’s water pump.
