GMC Sonoma Water Pump Parts Questions & Experts Answers
- Q: What are the three quick-checks to determine if the water pump is functioning properly while it is still installed on the engine for Chevrolet Blazer,S10,GMC Jimmy and Sonoma?A: Water pump failure can cause overheating and engine damage. There are three quick-checks to determine if the water pump is functioning properly. If any of these checks indicate problems, immediate replacement is necessary. One way to check is to inspect the weep hole for coolant leakage. Another way is to listen for a high-pitched squealing sound from the water pump. Excessive bearing wear can be identified by moving the water pump pulley. It is important to note that a water pump can be faulty even without howling or leaking water. To check for this, the pump must be removed.
- Q: How do I remove the water pump on Chevrolet Blazer,S10,GMC Jimmy and Sonoma?A: To remove the water pump, start by disconnecting the battery cable from the negative battery terminal. Then, drain the coolant and remove the upper radiator shroud and fan/clutch assembly. Next, take off the serpentine belt and water pump pulley. Disconnect the radiator hose and heater hose from the water pump. Unbolt the water pump, tapping it with a soft-lace hammer if necessary to break the gasket seal. Inspect the pump's impeller blades for corrosion and replace the pump if needed. To install the new water pump, clean the sealing surfaces of all gasket material on both the pump and block. Apply a thin layer of RTV sealant to both sides of the new gasket and install it on the water pump. Place the water pump in position and tighten the bolts to the specified torque. The rest of the installation procedure is the reverse of the removal. Finally, add coolant to the specified level, start the engine, and check for leaks in the water pump and hoses. Bleed the cooling system of any air.
