Built to meet the latest manufacturer-specified designs, ACDelco Water pumps, in both cast-iron and aluminum, are thoroughly pressure-tested to prevent leaks, and feature uniform wall sections and smooth coolant-flow cavities for efficient operation and superior engine protection. High-quality bearings, heat-treated impellers and coated seals mean long life and trouble-free ownership.
Tips to Help Prevent Water Pump Failure:
- Flush 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.
- Utilize 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.
- Never over-tighten your drive belts. Belts that are too tight may cause an overload on pump bearings, greatly reducing the life of the water pump.
- Inspect 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.
- Ensure 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.
- Inspect the thermostat and radiator cap. Examine your thermostat and radiator cap, and replace if they show signs of sticking or leaking.
