The thermostat is located at the end of the 1 1/2 " radiator hose on the left side of the car at the engine block where the hose connects. It is not easy to get at and you need open ended wrenches. It is tight and the bottom bolt ( there are 2 holding the thermostat housing on) is difficult with only partial turns using an open end wrench.
Follow the hose to from the rad to the block and there it is at the base of the housing where the hose connects. You need to disconect the air filter housing case and remove it. You will also need to disconnect the wire harnesses and a couple of hoses.
Make sure you look at which way the thermostat fits in the block so you do not put in the thermostat backwards.
Pull the fan relay censor out ( located in the intake manifold to the left of the housing with a2 wires going to it) to eliminate an air lock. Do this when the engine is running
and just back it out far enough to have a fluid flow out of it , then retighten the sensor. You can also get a Haynes Manual at the library for a step by step approach to repair problems.
