coolant mixture, up to the base of the filler
neck. See Engine Coolant on page 375

air bleed valve, close the valve. Otherwise,
close the valves after the radiator is filled.
5. Rinse or wipe any spilled coolant from the
engine and the compartment.
6. Start the engine and let it run until you can

®
coolant mixture through the filler neck until the
level reaches the base of the filler neck.
