Yes, you can drain the radiator on a 1989 Jaguar XJ6. To do this, locate the radiator drain plug, typically found at the bottom of the radiator, and place a container underneath to catch the coolant. Open the drain plug to allow the coolant to flow out, and make sure to close it once draining is complete before refilling with fresh coolant. Always ensure the engine is cool to prevent burns and handle the coolant properly, as it is toxic.
