AB-505 Directions:

1. Remove radiator cap (never remove a radiator cap while engine is hot) and pour entire contents into a full cool radiator. Replace the cap.
2. After engine has reached normal operating temperature, idle for 10-20 minutes with heater on.

DO NOT DRIVE.

3. Stop engine and allow to cool.
4. Remove radiator cap and open drain cocks. For best results, run water from a hose into the radiator just fast enough to overflow slightly. DO NOT ADD COLD WATER TO A HOT, EMPTY SYSTEM.
5. With engine idling, flush until liquid runs clear. Shut off engine and allow the system to drain completely. Close drain cocks.
6. Refill radiator with recommended concentration of Antifreeze/Coolant and water mixture. Replace radiator cap to fully closed position.
