Jaguar XF cooler temperature issue, operating lower than normal on Jaguar XF

Some Jaguar XF owners report experiencing lower-than-normal engine temperatures, which can be attributed to several potential causes. These include a stuck-open thermostat, low coolant levels, and a faulty coolant temperature sensor. Additionally, some users have noted that their temperature readings only reach between 80-85°C after extended driving, whereas normal operating temperatures should typically be around 81°C with minor variances. Rapid movement of the temperature gauge from cold to mid-line within 15 minutes of normal driving has also been observed. Other possible issues contributing to this problem may include a degenerating plastic coolant bottle, a radiator cap that is losing pressure, water loss through vaporization, broken water hoses, or a leaking water pump. It is advisable for owners to inspect these components to effectively diagnose and resolve any temperature-related concerns.
