FAQ - A1Yes. ACDelco Professional Water Pump Kits and Water Pumps are for both GM and non-GM vehicle applications.
FAQ - A2Yes. ACDelco Professional Water Pump Kits and Water Pumps are packaged with the gaskets, seals, and O-rings needed for installation.
FAQ - A3No. Water pumps can vary greatly in size and appearance depending on the vehicle they are designed for.
FAQ - A4Yes. 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 - A5Yes. 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 - A6No. 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 - Q2Do ACDelco Professional Water Pump Kits and Water Pumps come with installation components?
FAQ - Q3Do all water pumps look the same?
FAQ - Q4Can a malfunctioning water pump harm my engine?
FAQ - Q5Does the water pump affect the temperature inside the passenger compartment of my vehicle?
FAQ - Q6Does the water pump work when my vehicle is turned off?
Good Maintenance Practices - S1 B1Clean all excess dirt and debris from the water pump housing.
Good Maintenance Practices - S1 B2Run your vehicle to increase engine temperature, and ensure the system is pressurized.
Good Maintenance Practices - S1 B3Inspect 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 - S1 B4A 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.
Good Maintenance Practices - S1 HTips for Water Pump Inspection:
Good Maintenance Practices - S2 B1Determine the root cause of failure, particularly if the water pump failed prematurely.
Good Maintenance Practices - S2 B10After installation, pressure-test the system for leaks and check for sufficient fan blade clearance between the blade and radiator shroud.
Good Maintenance Practices - S2 B11Inspect related components in the cooling system, including your fan blades, fan clutch, engine mounts, radiator, belts and hoses, and reservoir.
Good Maintenance Practices - S2 B2Clean and reinstall the coolant recovery reservoir before flushing the cooling system.
Good Maintenance Practices - S2 B3Flush 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 - S2 B4Do not use any non-approved flush agents, and replace the coolant according to manufacturer's specifications.
Good Maintenance Practices - S2 B5Clean all sealing surfaces, and make sure all old gasket material is removed before installing your replacement component.
Good Maintenance Practices - S2 B6Never strike the water pump shaft, since this will damage the new water pump.
Good Maintenance Practices - S2 B7Torque all bolts according to the manufacturer's specifications, and adjust belts to proper tension (if applicable) to manufacturer's specifications.
Good Maintenance Practices - S2 B8Use sealant tabs only if recommended. Some sealant tabs or similar compounds may restrict coolant flow through the passages of some cooling systems.
Good Maintenance Practices - S2 B9With the new water pump installed, turn the hub by hand and check for rotation.
Good Maintenance Practices - S2 HTips for Water Pump Servicing & Installation:
Good Maintenance Practices - S3 B1Flush your cooling system whenever the water pump or other system components are replaced. This will help prevent contamination from entering the system, which may result in repeated failure.
Good Maintenance Practices - S3 B2Utilize quality coolant when refilling your cooling system with the recommended 50/50 coolant/water mix. Distilled water should be used, as hard tap water can leave mineral deposits in the cooling system and reduce coolant flow, or result in corrosion and seal damage. Contaminated or depleted coolant can also result in corrosion and seal damage, and lead to pump failure. Take care to select the correct coolant for your vehicle by consulting the vehicle manufacturer's service information.
Good Maintenance Practices - S3 B3Never overtighten your drive belts. Belts that are too tight may cause an overload on pump bearings, greatly reducing the life of the water pump.
Good Maintenance Practices - S3 B4Inspect the fan blade. If damage is not detected, bent blades, loose rivets, and cracks may result in premature bearing failure. If damage is found, do not try to repair the fan-the part should be replaced.
Good Maintenance Practices - S3 B5Ensure that your engine fan pulley (or clutch, if used) is seated properly on the pump's shaft. If the fan wobbles during rotation, vibration resulting in premature bearing wear may occur. Also check the fan clutch for wear and replace as necessary.
Good Maintenance Practices - S3 B6Inspect the thermostat and radiator cap. Examine your thermostat and radiator cap, and replace if they show signs of sticking or leaking.

Signs of Wear & Troubleshooting - S1 B1Leaking 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 & Troubleshooting - S1 B2Engine 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.
Signs of Wear & Troubleshooting - S1 B3Rumbling 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 & Troubleshooting - S1 B4Visible 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 pump failure, and should be addressed.
