How do you refill the coolant on a 2003 jaguar x type?

To refill the coolant on a 2003 Jaguar X-Type, first ensure the engine is cool. Open the hood and locate the coolant reservoir, which is typically a translucent plastic tank. Remove the cap and add the appropriate coolant mixture (usually a 50/50 mix of antifreeze and distilled water) until it reaches the "FULL" mark. Replace the cap securely and check for any leaks before starting the engine.
