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, make sure it is the correct fit for your vehicle.
