Chrysler recommends using a high-quality antifreeze/coolant that meets the requirements of Chrysler Specification MS-7170.
This specification is usually printed on the antifreeze/coolant container.
This antifreeze/coolant is a mixture of ethylene glycol and water, with a corrosion inhibitor added to protect the engine from rust and other forms of corrosion.
It is important to use the correct type of antifreeze/coolant, as the wrong type can damage the engine.
