Cooling System: Service and Repair

FILLING COOLING SYSTEM







CAUTION: Do not use well water or suspect water supply in cooling system. A 50/50 mixture of the recommended antifreeze coolant and distilled water is recommended.

NOTE: Cooling system fill procedure is critical to overall cooling system performance.

1. Close the radiator draincock.
2. Install the engine block drain plugs.
3. Attach one end of a 6.35 mm (0.250 in.) ID clear hose that is approximately 1200 mm (48 in.) long, to the bleed screw.
4. Route the hose away from the accessory drive belt, drive pulleys and cooling fan. Place the other end of hose into a clean container. The hose will prevent coolant from contacting the accessory drive belt when bleeding the system during the refilling operation.

NOTE: It is imperative that the cooling system air bleed screw be opened before any coolant is added to the cooling system. Failure to open the bleed screw first will result in an incomplete fill of the system.

5. Open the cooling system bleed screw.







6. Pour a 50/50 mix of Mopar(R) Antifreeze/Coolant, 5 Year/100,000 Mile Formula and distilled water into the coolant pressure bottle.
7. Slowly fill the cooling system until a steady stream of coolant flows from the hose attached to the bleed screw
8. Close the bleed screw and continue filling the system to the top of the COLD FILL RANGE.
9. Remove the hose from bleed screw.







10. Install the cap on the coolant pressure bottle.
11. Start and run the engine until it reaches operating temperature.
12. If removed, install front belly pan.

NOTE: The engine cooling system will push any remaining air into the coolant bottle within about an hour of normal driving. As a result, a drop in coolant level in the pressure bottle may occur.
