A water pump is one of the many components on your car that you don’t think about until it stops working. Replacing the water pump can be a complicated process; don’t wanna do it yourself without some mechanical expertise.

STEP ONE – GET A NEW PUMP

Know the year and model number of the vehicle as well as the engine size when you look for your new water pump. You may often find them in local auto parts stores as well as online.

STEP TWO – PREPARE THE CAR

Let the engine to cool completely and disconnect the battery. Put a drain pan under the engine and drain the entire cooling unit.

STEP THREE – TAKE OUT BELTS, HOSES, AND THE PUMP

To replace the water pump, you’ll need to remove the drive belts and perhaps the engine pulley. Remove any parts that block your access to the water pump (there may be several) and detach any hoses from the pump. Unbolt and remove the pump.
