Default Low Coolant Light

My 2002 XKR low coolant light goes on everyday after around 7 miles of driving. The coolant tank is full and I changed out the coolant reservoir for brand new and tried 2 new sensors. Any ideas? Thanks

I'm going to make a guess that the expansion tank you fitted was the aftermarket one, possibly from SNG Barratt? Rather than me explain, have a read of: https://www.jaguarforums.com/forum/x...cement-212844/

It's always good practise, where possible, to test parts (especially switches) before you install in the car. The tank's float switch is probably bad. Check out Sam1174's test on Youtube.

once again you guys are right on. It’s the brand new reservoir/tank that’s at fault. The magnet is either stuck, dislodged or non existent. When the electrical expert took a magnet to the sensor it worked perfectly. The $75 electrical diagnostics saved me from an expensive ECM repair or replacement that wouldn’t have solved the problem. Thanks Guys
