hi jim,open your bonnet & looking at the radiator follow the top hose back to the engine,where this hose meets the engine this is the thermostat housing their should be 3 bolts/nuts holding this together remove these bolts/nut's once you remove the top of the housing you should see the thermostat remove old one & re-fit new one then put the housing back tgether in the reverse of taking it apart.
