  • Park car and get her on jack stands
  • Put drain pain under radiator and drain that sucker via drain plug on bottom drivers side
  • Disconnect hose that attaches to the front of housing.
  • I believe there is a sensor there too..disconnect wire to sensor. Be careful though, the heat can make that plastic brittle
  • Unbolt housing from block via 3 bolts on side of housing
  • Remove housing
  • Take front piece off the housing to remove the thermostat. **Take note of the little hole on the front/top of thermostat. When you put it back in, this hole should be on the top
  • Remove tiny clips from silver plugs in housing and swap them into the new housing. You may have to replace the o-rings, mine got perma-sealed to the housing from heat and chemicals and needed to be replaced.
  • Remove clip and sensor from housing and swap to new housing...again, be careful. Heat can make plastic brittle.
  • Put thermostat in new housing (with hole facing u)
  • Put new oring in place
  • Bolt housing to block
  • Re attach hose to front of housing
  • fill up car with new coolant/water
  • FIN!!




Extras I might recommend, o-rings for the silver plugs in housing and possibly a new sensor. You might want to take this opportunity to switch to the lower temp Thermostat, if your mods dictate.



hope this helps
