Thermostat Removal
Stop engine.Disconnect negative (-) battery cable at battery.
Do not drain engine coolant until the coolant temperature is below operating temperature. Then loosen drain cock slowly to relieve any excess pressure.
Remove coolant from cooling system.
Fig. 1-Thermostat CoverDisconnect upper radiator hose from thermostat cover (Fig. 1).Remove thermostat cover.Remove gasket.
Fig. 2-ThermostatLift thermostat (Fig. 2) out of thermostat housing.Repair
Fig. 3-Thermostat OpenIf engine is running too hot or too cold inspect thermostat for defects. Test in hot water for proper opening and closing.Installation
Some thermostats are marked "TO RAD", "THIS SIDE TOWARD RADIATOR", or "TOWARD RADIATOR" to indicate the top side. Put thermostat in housing so that top side is toward thermostat cover.
Fig. 4-Top SideIf thermostat is not marked, find the top side (Fig. 4). Put thermostat in housing so that top side is toward thermostat cover.
Fig. 5-Cap ScrewUsing a new gasket, install thermostat cover. Put cap screws (Fig. 5) through thermostat cover into thermostat housing. Tighten cap screws to 35 lb-ft (47 N m) (5 kg-m).Connect upper radiator hose to thermostat cover.Fill cooling system to proper level with proper coolant.Connect negative (-) battery cable to battery negative (-) terminal.Start engine.Check for leaks at hose connection and around gasket area.
