Good Maintenance Practices - Section 1 - Bullet 1
Clean all excess dirt and debris from the water pump housing.
Good Maintenance Practices - Section 1 - Bullet 2
Run your vehicle to increase engine temperature, and ensure the system is pressurized.
Good Maintenance Practices - Section 1 - Bullet 3
Inspect 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 1 - Bullet 4
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.
Good Maintenance Practices - Section 1 - Header
Tips for Water Pump Inspection:
Good Maintenance Practices - Section 3 - Bullet 1
Clean and reinstall the coolant recovery reservoir before flushing the cooling system.
Good Maintenance Practices - Section 3 - Bullet 10
Inspect related components in the cooling system, including your fan blades, fan clutch, engine mounts, radiator, belts and hoses, and reservoir.
Good Maintenance Practices - Section 3 - Bullet 2
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.
Good Maintenance Practices - Section 3 - Bullet 3
Do not use any non-approved flush agents and replace the coolant according to manufacturer's specifications.
Good Maintenance Practices - Section 3 - Bullet 4
Clean all sealing surfaces, and make sure all old gasket material is removed before installing your replacement component.
Good Maintenance Practices - Section 3 - Bullet 5
Never strike the water pump shaft, since this will damage the new water pump.
Good Maintenance Practices - Section 3 - Bullet 6
Torque all bolts according to the manufacturer's specifications and adjust belts to proper tension (if applicable) to manufacturer's specifications.
Good Maintenance Practices - Section 3 - Bullet 7
Use 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 - Section 3 - Bullet 8
With the new pump installed, turn the hub by hand and check for rotation.
Good Maintenance Practices - Section 3 - Bullet 9
After installation, pressure-test the system for leaks and check for sufficient fan blade clearance between the blade and radiator shroud.

Signs of Wear & Troubleshooting - Section 1 - Bullet 1
Leaking 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 - Section 1 - Bullet 2
Engine 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 - Section 1 - Bullet 3
Rumbling 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 - Section 1 - Bullet 4
Visible 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.
