| 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. |
