It's crucial to use a coolant that meets Chrysler's specifications. The exact specification might be listed in your owner's manual, but a common and widely available type is a HOAT (Hybrid Organic Acid Technology) coolant. Look for a coolant that specifically states it's compatible with aluminum engines and meets the relevant Chrysler specifications. Using the wrong type of coolant can cause serious engine damage.
When in doubt, consult your owner's manual or a trusted auto parts store. They can help you choose the correct coolant for your specific vehicle.
