What the correct type of antifreeze for a 2003 jaguar XJ8?

For a 2003 Jaguar XJ8, the recommended type of antifreeze is a phosphate-free, ethylene glycol-based coolant that meets the Jaguar specification. Look for a coolant that conforms to the ASTM D3306 standard, or specifically, a 50/50 mix of distilled water and antifreeze. It's essential to avoid using silicate-based coolants, as they can harm the engine's cooling system. Always check the owner's manual for specific recommendations.
