Filling and Bleeding

1. To prevent loss of coolant when draining the radiator, attach a hose on the radiator draincock and drain the coolant from the radiator into a clean container.
2. Drain the radiator, open the draincock located at the bottom of the radiator and remove the radiator or supply tank cap. The cylinder block of the V-8 engine is drained by removing the drain plugs located on both sides of the block.
3. To fill the cooling system, install the cylinder block drain plug(s) and close the radiator draincock. Disconnect the heater outlet hose at the water pump to bleed or release trapped air in the system. When the coolant begins to escape, connect the heater outlet hose.
4. Fill the radiator until the coolant is between the cap seal in the filler neck to 38 mm (1.5 inches) below the cap seal. Install cap.

WARNING: Do not stand in line with or near radiator fan when engine is running.

5. Start engine, warm up, shut off engine. Allow engine to cool, remove cap and check coolant level. Fill as required.

WARNING: Never remove the radiator cap under any conditions while the engine is operating. Failure to follow these instructions could result in damage to the cooling system or engine and/or personal injury. To avoid having scalding hot coolant or steam blow out of the radiator, use extreme care when removing the cap from a hot radiator. Wait until the engine has cooled, then wrap a thick cloth around the radiator cap and turn it slowly to the first stop. Step back while the pressure is released from the cooling system. When you are sure all the pressure has been released, press down on the cap (still with a cloth), turn and remove it.
