    Q:
    What are the ways to check the operation of a water pump on an engine for Chevrolet Express and GMC Savana? Posted by Customer
    A:
    Water pump failure can lead to overheating, there are several ways to check the operation of the water pump while it is installed on the engine. Excessive bearing wear can be identified by attempting to move the water pump pulley horizontally or vertically. To replace the water pump, the coolant must be drained and various components such as the air cleaner assembly, radiator shroud, fan/clutch assembly, and drive removed. The specific steps for removal and installation vary depending on the engine type. Coolant should be added to the specified level and the coolant level checked. Also, it is important to bleed the cooling system of air and check for any coolant leaks around the water pump and hoses.
