Allow the engine to continue idling until the lower radiator to coolant pump hose becomes hot. cycle the engine speed up to about 3,000 rpm and back to idle 5 times. after the air has been released, fill the radiator. install the surge tank cap. the arrows on the radiator pressure cap must line up with the coolant recovery tube. Install the thermostat housing to the intake manifold. tighten the thermostat housing bolts to 18 ft. lbs. (25 nm). refill the cooling system using a 50 50 mixture of water and ethylene glycol antifreeze. install the air cleaner and beauty panel, if removed. start the engine and check for coolant leaks.
