Product DescriptionGM Genuine Parts Engine Water Pump Gaskets are designed, engineered, and tested to rigorous standards, and are backed by General Motors. These gaskets are used between the water pump housing and the engine block or another component to seal the interface between the components. The gasket may be made of fiber or a rubberized composite material that provides a liquid-tight connection. The gasket helps keep the engine coolant in and keeps air out. 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). ⚠<b> WARNING:</b> Cancer and Reproductive Harm - www.P65Warnings.ca.gov

Good Maintenance Practices - Section 2 - Bullet 3Inspect for leakage at the water pump outlet housing or the rear cover gasket, and leakage at the water pump vent or weep hole.
Good Maintenance Practices - Section 2 - Bullet 4A 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.
Programming RequiredNo

Good Maintenance Practices - Section 2 - Bullet 2Run your vehicle to increase engine temperature, and ensure the system is pressurized.
Good Maintenance Practices - Section 2 - HeaderTips for Water Pump Inspection:
Signs Of Wear &#38; Troubleshooting - Section 1 - Bullet 1Leaking Coolant - Puddles of coolant under your vehicle, a constant drip or stream of coolant from the water pump's weep hole, or a constantly empty or low coolant reservoir are all signs of potential water pump wear, and may be caused by cracks in the pump, or seal or gasket failures.
Signs Of Wear &#38; Troubleshooting - Section 1 - HeaderSigns of wear for engine water pump seals include but are not limited to:
Faq - Answer 6No. Your vehicle's water pump keeps coolant moving as long as the engine is running and stops when the engine is turned off. If you want to be able to circulate coolant for a short time after the engine has been turned off, an auxiliary electric water pump is needed.
Faq - Answer 5Yes. As part of regular cooling system operation, the water pump sends hot coolant to the heater core of your engine, which transfers heat into the passenger cabin of your vehicle. If this hot coolant is unable to reach the heater core, then this heat transfer cannot occur, and your passenger compartment remains colder than you want.
Faq - Answer 4Yes. The water pump is responsible for moving coolant through your vehicle's cooling system, keeping the heat generated by your engine at acceptable levels, and helping prevent overheating. A malfunctioning water pump can cause your engine to overheat, which may result in severe and costly engine damage.
Faq - Answer 3No. Water pumps can vary greatly in size and appearance depending on the vehicle they are designed for.
Faq - Answer 2Yes. ACDelco GM Original Equipment parts are equivalent to your GM vehicle's original factory components.
Faq - Answer 1Yes. Always consult the Vehicle Owner’s manual or an expert technician before making any repairs or adjustments

Good Maintenance Practices - Section 3 - Bullet 7Use sealant tabs only if recommended. Some sealant tabs or similar compounds may restrict coolant flow through the passages of some cooling systems.
Faq - Question 6Does the water pump work when my vehicle is turned off?
Good Maintenance Practices - Section 3 - Bullet 6Torque all bolts according to the manufacturer's specifications and adjust belts to proper tension (if applicable) to manufacturer's specifications.
Faq - Question 5Does the water pump affect the temperature inside the passenger compartment of my vehicle?
Signs Of Wear &#38; Troubleshooting - Section 1 - Bullet 2Engine Overheating - If your vehicle's engine overheats, it may not be receiving the required coolant flow. Make sure that your vehicle's cooling system contains the proper level of coolant.
Good Maintenance Practices - Section 3 - Bullet 1Clean and reinstall the coolant recovery reservoir before flushing the cooling system.
Signs Of Wear &#38; Troubleshooting - Section 1 - Bullet 3Rumbling Noise in the Pump - A rumbling, squeaking, or screeching noise near the front of your vehicle when you start it may indicate a malfunctioning water pump bearing.
Signs Of Wear &#38; Troubleshooting - Section 1 - Bullet 4Visible Component Wear - Worn seals, corrosion, cavitation/pitting of pump components, or a loose or wobbly pump shaft are all signs of wear that may lead to water pump failure and should be addressed.
Good Maintenance Practices - Section 3 - Bullet 3Do not use any non-approved flush agents and replace the coolant according to manufacturer's specifications.
Good Maintenance Practices - Section 3 - Bullet 2Flush 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.
Good Maintenance Practices - Section 3 - Bullet 10Inspect related components in the cooling system, including your fan blades, fan clutch, engine mounts, radiator, belts and hoses, and reservoir.
