You will need a 1/2" socket with ratchet, and a 1/2" wrench for the actual removal of the thermostat housing. First, remove the air duct from the air filter housing and the air intake connection to the engine. Set aside. Next, remove the upper radiator hose from where it connects to the engine by loosening the hose clamp. At the other end of this part where the hose was removed from is the "L" shape that houses the thermostat and bolts to the engine. This part (housing) has two bolts. The top bolt will require the use of an extension on your ratchet which you will need to insert between the water bypass pipe and the exhaust heat shield before coupling with the 1/2" socket. Loosen the top bolt. The bottom bolt will require the use of the 1/2" wrench, as the socket will not fit due to the location of the heat shield. NOTE: the bottom bolt only needs to be LOOSENED and not removed, as the housing has an open "C" at the lower bolt location allowing the housing to pivot upward from that bolt. After removing the top bolt and loosening the lower bolt, you can pivot the "pipe" end of the housing downward and carefully maneuver the housing out of its location. You should now see the thermostat. Clean surfaces of the engine and housing well. Insert the new thermostat with the "spring" into the engine and the "bell" outward. Be sure the seal is seated properly into its socket in the engine. Position the housing carefully, making sure not to move the thermostat out of position. Reassembly is the reverse of removal. In my case, I did not use any gasket seal. The thermostat has a rubber seal on it which works well on its own. Adding gasket seal may make removing the housing in the future more difficult

Do the radiator fans come on? Turn on the A/C which should start the fans automatically. Does that stop the overheating? Replace the temperature sensor if engine heat doesn't turn on the fans (A/C off). The water pump can be checked by removing the thermostat and lowering the water level in the radiator until the tubes are exposed at the top. With the engine cold, start it and watch for water being pumped into the radiator (it should be a fair quantity), which points to an effective water pump. Shut off the engine, replace the thermostat, and refill with coolant.
