a thermostat allows rapid engine warm up as it will stay shut until the engine reaches operation temperate and then it will open and allow the coolant to return to the radiator so it can be cooled and kept at a certain temp. the thermostat is on the thermostat housing on the front right side of your rocker cover.. its easy to change, unbolt the top, take old on out and put new one in..
they are fairly cheap and can be obtained at coventrys, make sure its a genuine part too.
good luck
