Disconnect battery negative cable. Remove air intake duct. With engine cool, drain engine coolant below thermostat level. Never open cooling system with engine hot. Failure to follow this warning may cause personal injury. Disconnect radiator hose from thermostat housing. Remove thermostat housing retaining nuts, then the housing, gasket and thermostat. Reverse procedure to install noting the following: Prior to installation, ensure thermostat gasket area is thoroughly clean. Install thermostat with new gasket. Torque thermostat housing retaining nuts to 89 inch lbs. Refill and bleed cooling system as needed.
