NOTES:
  • Do not attempt to repair the thermostat. It should be replaced if it is not operating properly.

REMOVAL

  1. Disconnect ground cables from both batteries.
  2. Drain coolant from radiator until coolant level is below thermostat.
  3. Remove accessory drive belt.
  4. Disconnect alternator electrical connectors and remove alternator.
  5. Remove the water outlet housing attaching bolts. Bend the radiator upper hose upward and remove the thermostat and gasket.

INSTALLATION

  1. Clean the water outlet housing gasket surfaces. Coat a new outlet housing gasket with Perfect Seal Sealing Compound BA-19554-A (ESR-M18P2-A) or equivalent. Position the water outlet housing gasket on crankcase opening.

  4. Install alternator and connect electrical connectors.
  5. Install accessory drive belt.
