- Q:How to check and replace a water pump in an engine for Chevrolet Trailblazer? Posted by Customer
- A:The main water pump is a crucial component of the engine and its failure can lead to overheating and severe damage. There are several ways to check if the water pump is functioning properly, such as inspecting for coolant leakage from the weep hole or listening for a high-pitched squealing sound indicating bearing failure. Excessive bearing wear can be identified by attempting to move the water pump pulley vertically or horizontally. If the impeller fins on the back of the pump are corroded, the pump may need to be replaced. To replace the water pump, the battery cable should be disconnected, coolant drained, and various components such as the air intake duct, radiator shroud, and fan clutch assembly removed. The water pump pulley and bolts can then be removed, and the sealing surfaces cleaned. During installation, a new gasket should be applied with RTV sealant, and the pulley and other components reinstalled. The cooling system should be refilled and bled, and the engine checked for coolant leaks. The procedure for replacing the auxiliary water pump is similar, involving the removal of various components and disconnecting the heater hoses and connector. The installation process is then reversed, and the cooling system refilled and checked for leaks.Posted by GMPartsGiant Specialist
