1999 Cadillac Seville Water Pump Replacement Cost

If the water pump is not maintaining good coolant circulation, the engine will overheat, causing leaks, possible head gasket damage and ultimately a failed motor. If your car begins to overheat, pull off the road and shut the engine off as quickly as you safely can. You will have to have your car towed to a repair shop.

This depends on the model of car and its driving conditions. The water pump does not wear like a tire or a ball joint, but eventually the bearing or impeller can fail inside the pump.

The technician will check for leaks around the water pump area. While the engine runs, a stethoscope may also be used to check for noise from the water pump bearing. If it's not buried away, the belt driving the pump, as well as its pulley, will be visually inspected. For electric water pumps on some newer cars, the engine's computer will be checked for codes, and tests will be performed to determine the proper repair.

To replace the water pump, the cooling system is drained and the fan belt or timing belt and pulleys are removed. Depending on which belt drives the pump, that belt and other related components will be removed, followed by the pump itself. Engine surfaces are cleaned, a new water pump and gasket are installed, and the cooling system is refilled.

When replacing the water pump, the drive belts and/or timing belt may need to be removed. The belts should be replaced if they show signs of wear or coolant damage.
