the thermostat is very easy to replace.first u need to locate the radiator hoses.there is two.one lower and one upper.the upper is on top of the engine..the lower is at the back of the engine.locate the lower hose...trace it all the way to the back of the engine.u will see it hook up to a small triangular shape thing.and that has 2 screws.that is where the thermostat go.first loosing up the hose.then unscrew the screws.carefullyp ply out the housing.take out the thermolstat and put the new one in.clean the housing if it need cleaning.u also to replace the gasket.good luck.
