What kind of antifreeze for 2003 jeep liberty sport?

A 2003 Jeep Liberty Sport requires 50/50 mix of ethylene glycol-based antifreeze and distilled water. It's crucial to use a HOAT (Hybrid Organic Acid Technology) antifreeze. This type of antifreeze is compatible with the aluminum components in the cooling system. Do not use traditional green antifreeze (which is often IAT - Inorganic Additive Technology) as it can lead to corrosion.

To be absolutely certain, check your owner's manual. It will specify the correct type and concentration of antifreeze for your specific vehicle. The manual will also likely have information on the proper procedure for flushing and refilling your cooling system.

If you can't find your owner's manual, you can usually find a digital version online through the Jeep website or a reputable automotive parts website. You can also contact a Jeep dealership or a trusted mechanic for assistance.
