Engine Block Heater
WARNING: This page is about a different car, the 2019 Jaguar XJ and 2018 Jaguar XJ. However, it is still accessible from the selected car via links, so may be relevant.
For vehicle markets subject to very cold climatic conditions, an engine block heater is installed in place of the cylinder block drain plug. The engine block heater is either a 110 V AC (Alternating Current) or 240 V AC electric heater element, depending on the market, which can be connected to a domestic power supply via a connector in the left side grill of the front bumper.
