What to Do When Jaguar Coolant Level is Too Low?
1 Answers
If the coolant level is indeed too low, simply add coolant to the specified level; if the level is normal, then the sensor is faulty and the level sensor needs to be replaced. Below are the specific causes and solutions: 1. Instrument cluster failure: Refer to the wiring diagram based on the symptoms—the coolant level sensor is powered by the instrument cluster. Upon removing the G-1-D-13/1 grounding point, it was found that the fixing screw was corroded. Solution: Clean and reassemble, then test to confirm the fault is resolved. 2. High resistance due to rust at the grounding point causes unstable signals. Solution: Remove rust from the grounding point and replace the screw.
