The 2004 Chrysler Sebring Convertible requires
a 50/50 mix of ethylene glycol-based coolant and distilled water. It's crucial to use a coolant that meets
Chrysler's specifications, often denoted as
MS-7170. You can find coolants specifically labeled as meeting this standard at auto parts stores.
Never use just water or other types of antifreeze. Using the correct coolant mixture protects against freezing in cold weather and overheating in hot weather, and also helps prevent corrosion in the engine's cooling system.
