Draining and Refilling Cooling System
DRAINING COOLING SYSTEM - ALL GAS ENGINESWARNING: DO NOT REMOVE CYLINDER BLOCK DRAIN PLUGS OR LOOSEN RADIATOR DRAINCOCK WITH SYSTEM HOT AND UNDER PRESSURE. SERIOUS BURNS FROM COOLANT CAN OCCUR.
DO NOT WASTE reusable coolant. If solution is clean, drain coolant into a clean container for reuse.
1. Attach one end of a hose to the draincock. Put the other end into a clean container.
2. DO NOT REMOVE THE RADIATOR CAP when draining the coolant from the reservoir/overflow tank. Open radiator draincock and when the tank is empty, remove the radiator cap and continue draining the cooling system.
3. If draining the entire engine, remove the cylinder block drain plugs (1).
REFILLING COOLING SYSTEM - ALL GAS ENGINES
The use of aluminum cylinder blocks, cylinder heads and water pumps requires special corrosion protection. In order to maintain the required protection for these components and cooling system performance, only use the appropriate fluid when servicing the vehicle. This coolant offers the best engine cooling without corrosion when mixed with 50% distilled water to obtain a freeze point of -37°C (-35°F). If it loses color or becomes contaminated, drain, flush, and replace with fresh properly mixed coolant solution.

Clean cooling system prior to refilling.
1. Install cylinder block drain plugs. Coat the threads with Mopar Thread Sealant with Teflon.
2. Close radiator petcock.
3. Fill cooling system with the antifreeze mixture.
4. Fill coolant reserve/overflow tank to MAX mark on bottle.
5. Start and operate engine until thermostat opens (upper radiator hose warm to touch).
6. If necessary, add antifreeze mixture to the coolant reserve/overflow tank. This is done to maintain coolant level between the MAX and MIN marks. The level in the reserve/overflow tank may drop below the MIN mark after three or four warm-up and cool-down cycles.
