Adding Additional Coolant

Figure 13-Coolant Bottle Cold Fill Level:

When additional coolant is needed, it should be added to the coolant pressure bottle. Use only 50/50 concentration of Mopar(R) Extended Life Coolant (orange in color) or the equivalent and distilled water. The Mopar(R) Extended Life Coolant must not be mixed with other (green in color) coolants. If this occurs, a reduction in the extended service interval will result.

WARNING: Do not open cooling system when hot and under pressure because personal injury and serious burns from coolant can occur. Allow engine to cool before servicing cooling system.


1. Try squeezing the upper radiator hose to determine if the system is still pressurized.
2. Place a shop towel over the pressure cap and turn to the first stop. Wait to see if any pressure is released. When no pressure is released, press down on the cap and turn to the second stop. Remove cap.

NOTE: If the coolant pressure is bottle completely empty, refer to Filling Cooling System.

3. If there is some coolant in coolant pressure bottle, slowly fill coolant pressure bottle.

CAUTION: Do not use well water, or suspect water supply in cooling system. A 50/50 ethylene glycol and distilled water mix is recommended.
