Follow upper radiator hose to engine will find thermostat cover, take hose off and remove any electrical connections or hoses and remove bolts or nuts, if stuck tap easily and remove thermostat and replace making sure new thermostat is right side up do so by looking at old one when taken out, install new gasket making sure housing is cleaned of old gasket retighten nuts or bolts add new antifreeze.
