Cooling System - Draining and Filling

WARNING: Do not remove the cylinder block drain plugs or loosen the radiator draincock with system hot and under pressure serious burns from coolant can occur.

NOTES:
^ DO NOT WASTE reusable coolant. If the solution is clean, drain the coolant into a clean container for reuse.
^ DO NOT remove the radiator cap when draining the coolant from the reserve/overflow tank. Open the radiator drain cock and when the tank is empty, remove the radiator cap. The coolant does not have to be removed from the tank unless the system is being refilled with a fresh mixture.

DRAINING
1. Drain the coolant from the radiator by loosening the petcock.
2. Drain coolant from engine by removing drain plug at left rear side of block.

REFILLING
1. Tighten the radiator petcock and the cylinder block drain plug.
2. Fill system using a 50/50 mixture of water and antifreeze as described in the Coolant section of this group. Fill radiator to top and install radiator cap. Add sufficient coolant to reserve/overflow tank to raise level to FULL mark.
3. With heater control unit in the HEAT position, operate engine with radiator cap in place.
4. After engine has reached normal operating temperature, shut engine off and allow it to cool.
5. Add coolant to reserve/overflow tank as necessary. Only add coolant when the engine is cold. Coolant-level in a warm engine will be higher due to thermal expansion.
