1. Clean and reinstall the coolant recovery reservoir before flushing the cooling system.
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.
3. Do not use any non-approved flush agents, and replace the coolant according to manufacturer's specifications.
4. Clean all sealing surfaces, and make sure all old gasket material is removed before installing your replacement component.
5. Never strike the water pump shaft, since this will damage the new water pump.
6. Torque all bolts according to the manufacturer's specifications, and adjust belts to proper tension (if applicable) to manufacturer's specifications.
7. Use sealant tabs only if recommended. Some sealant tabs or similar compounds may restrict coolant flow through the passages of some cooling systems.
8. With the new pump installed, turn the hub by hand and check for rotation.
9. After installation, pressure-test the system for leaks and check for sufficient fan blade clearance between the blade and radiator shroud.
10. Inspect related components in the cooling system, including your fan blades, fan clutch, engine mounts, radiator, belts and hoses, and reservoir.
