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?

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.

How do I remove the water pump on Chevrolet Blazer,S10,GMC Jimmy and Sonoma?

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.

Chevrolet Blazer Water Pump

Chevrolet Blazer's Water Pump is an essential attribute that pumps coolant from the radiator to the engine to be soaked by heat created by the combustion process. The majority of today's Water Pumps contain aluminum; fitted with a shaft that has bearings; belt driven pulley; and an impeller to channel the coolant. Sign of a faulty Water Pump is leaking of the coolant, noisy bearings due to wear and tear, and finally overheating of the engine. While Performance Water Pumps are made for high-performance engines, they increase the coolant flow rate and decrease the power consumption. Another type of water pumps is the Electric Water Pumps which have benefits like separate coolants from the engine revolutions per minute and, cool the engine after it has been turned off.

Each OEM Chevrolet Blazer Water Pump we offer is competitively priced and comes with the assurance of the manufacturer's warranty for the part. Furthermore, we guarantee the speedy delivery of your orders right to your doorstep. Our hassle-free return policy is also in place for your peace of mind.
