Description:
GM Genuine Parts Engine Water Pumps are designed, engineered, and tested to rigorous standards, and are backed by General Motors. These pumps circulate coolant through your vehicle's radiator and engine system to help maintain proper engine temperature and performance. GM Genuine Parts are the true OE parts installed during the production of or validated by General Motors for GM vehicles. Some GM Genuine Parts may have formerly appeared as ACDelco GM Original Equipment (OE). WARNING: Cancer and Reproductive Harm www.P65Warnings.ca.gov
Features and Benefits:
- Coated seals with a stainless steel spring for durability
- GM Genuine Parts are designed, engineered and tested to rigorous standards, and are backed by General Motors
- GM engineers design and validate OE parts specifically for your Chevrolet, Buick, GMC, or Cadillac vehicle
- GM regularly updates production and service part designs to integrate new materials and technologies
- Heat-treated impeller shafts supported by high-quality ball/roller bearings for smooth, reliable operation
- Some GM Genuine Parts may have formerly appeared as ACDelco GM Original Equipment (OE)
- Thoroughly tested for leak-resistant performance
- Uniform wall sections and smooth coolant-flow cavities for efficient operation
- – A stain around the weep hole is acceptable. However, if a weep occurs with the engine running and the coolant system pressurized, then the water pump should be replaced.
- – After installation, pressure-test the system for leaks and check for sufficient fan blade clearance between the blade and radiator shroud.
- – Clean all excess dirt and debris from the water pump housing.
- – Clean all sealing surfaces, and make sure all old gasket material is removed before installing your replacement component.
- – Clean and reinstall the coolant recovery reservoir before flushing the cooling system.
- – Do not use any non-approved flush agents and replace the coolant according to manufacturer's specifications.
- – Flush the cooling system completely, using power flush equipment or thermal cycling the system with clean water three times. The most effective method of system flushing is to use a coolant exchanger, following the manufacturer's operating instructions.
- – Inspect for leakage at the water pump outlet housing or the rear cover gasket, and leakage at the water pump vent or weep hole.
- – Inspect related components in the cooling system, including your fan blades, fan clutch, engine mounts, radiator, belts and hoses, and reservoir.
- – Never strike the water pump shaft, since this will damage the new water pump.
- – Run your vehicle to increase engine temperature, and ensure the system is pressurized.
- – Torque all bolts according to the manufacturer's specifications and adjust belts to proper tension (if applicable) to manufacturer's specifications.
- – Use sealant tabs only if recommended. Some sealant tabs or similar compounds may restrict coolant flow through the passages of some cooling systems.
- – With the new pump installed, turn the hub by hand and check for rotation.
