YEA, ITS A TOUGHY. ITS GOING TO BE IN THE BACK. RIGHT UNDER THE THROTTLE BODY. MOVE THE AIR CLEANER OUT THE WAY AND THERES POSSIBLY ONE OR 2 HEATER HOSES WITH A BRACKET ON THEM ALONG THE THERMOSTAT HOUSING.
 
There's were two engines available.

On the 3.8 litre, it's a straight forward procedure to replace the thermostat. Just remover the upper rad hose, stat housing & stat.

He must have the 3.1 litre engine. To remove the thermostat, you have to first remove the exhaust crossover pipe to gain access to the thermostat housing. Then, it's as above with the 3.8 litre.
