Operation - Engine Cooling System Requirements

WARNING: This page is about a different car, the 2003 Dodge Intrepid, 2003 Chrysler Intrepid, 2003 Chrysler Concorde, and 2003 Chrysler 300M. However, it is still accessible from the selected car via links, so may be relevant.

The engine cooling system is designed to develop internal pressure of 97 to 123 kPa (14 to 18 psi). Wait 15 minutes (after the engine is shut off), or until safe temperature and pressure is attained, before opening the cooling system. Refer to Cooling (Refer to COOLING ). Coolant temperature can be checked using the scan tool (DRBIII®).

When additional coolant is needed, it should be added to the coolant pressure bottle. Use only 50/50 mix of Mopar® Antifreeze/Coolant, 5 Year/100,000 Mile Formula (orange in color), or the equivalent and distilled water. This coolant must not be mixed with other (green in color) coolants. If this occurs, a reduction in the extended service interval will result. Refer to SERVICE & ADJUSTMENT SPECIFICATIONS for service schedule information).

CAUTION: Do not add additional inhibitors, anti-rust products, or soluble oil (sold as "water pump lubricants"). These products may not be compatible with the engine coolant.

Refer to Cooling for cooling system procedures (Refer to COOLING ).
