Cylinder Block Drain Plug/Heater Unit
WARNING: This page is about a different car, the 2002 Jaguar XKR and 2002 Jaguar XK8. However, it is still accessible from the selected car via links, so may be relevant.
The coolant drain plug is located on the rear left side of the cylinder block.
On vehicles supplied with a cold climate package (i.e. vehicles operating in conditions regularly below -30 °C) a cylinder block heater unit is fitted instead of the drain plug.
