If you follow the lower radiator hose from the radiator, to where it connects to the engine- this is the thermostat housing. The thermostat is inside:

 

  • Raise vehicle on hoist.
  • Disconnect the lower radiator hose from the water inlet connection.
  • Remove the two water inlet connection retaining bolts. Remove the water inlet connection.
  • Remove the O-ring seal and water thermostat from the water thermostat housing. Inspect O-ring for damage and replace if necessary.
