Water Pump Installation:

  1. When mounting the new pump, be sure the new gasket matches the surfaces to be sealed. Lightly coat both sides of the gasket with gasket sealer and position it on the engine. Also, lightly coat the threads of any bolts threading into a coolant passage with a non-hardening sealer. Install the new pump and attaching bolts (hand tight) in their original positions. Give the pump shaft a quick spin to check for free operation. Tighten the pump mounting bolts, using care not to over tighten, as possible pump damage may result.

  2. Reconnect all hoses replacing those that feel brittle, mushy or are cracked. Be especially critical of bypass hoses, or others that may be difficult to replace after assembly is complete. Use new clamps and apply sealant on any corroded hose connections. Verify that hoses are positioned to clear all moving parts and that the clamps will not contact pulleys, brackets or the fan.

  3. Remount other components that were removed earlier, referring cars repair manual if needed. Reinstall the belts for each component as you go, using new ones if the old ones are cracked, glazed or frayed. To tighten the belts, put tension on them by using a soft piece of wood as a lever, prying the component outward until the belt is tight. In most cases, applying hand pressure is the best method for tightening. Whatever method you choose, be careful to avoid damage to other engine components.

  4. Check all of the hose connections for tightness, then close the radiator drain, and add your coolant in the proper mixture.

  5. Reconnect the negative battery cable. Start the engine and check for leaks and the proper operation of all components disturbed during the process. The heater valve must be open, (heat on, temp on hot) to assure complete circulation of coolant. Run the engine without radiator cap until it reaches normal operating temperature to purge the system of air. Top off the radiator and reinstall the radiator cap. Any further coolant level checks should be done at the coolant reservoir only.
