Features and Benefits:

• – 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.
• – After installation, pressure-test the system for leaks and check for sufficient fan blade clearance between the blade and radiator shroud.
• – Clean all excess dirt and debris from the water pump housing.
• – Clean all sealing surfaces, and make sure all old gasket material is removed before installing your replacement component.
• – Clean and reinstall the coolant recovery reservoir before flushing the cooling system.
• – Do not use any non-approved flush agents and replace the coolant according to manufacturer's specifications.
• – 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.
• – Inspect for leakage at the water pump outlet housing or the rear cover gasket, and leakage at the water pump vent or weep hole.
• – Inspect related components in the cooling system, including your fan blades, fan clutch, engine mounts, radiator, belts and hoses, and reservoir.
• – Never strike the water pump shaft, since this will damage the new water pump.
• – Run your vehicle to increase engine temperature, and ensure the system is pressurized.
• – Torque all bolts according to the manufacturer's specifications and adjust belts to proper tension (if applicable) to manufacturer's specifications.
• – Use sealant tabs only if recommended. Some sealant tabs or similar compounds may restrict coolant flow through the passages of some cooling systems.
• – With the new pump installed, turn the hub by hand and check for rotation.
• Before purchasing and installing an engine water pump cover gasket, make sure it is the correct fit for your vehicle.
