Coolant sensor problem.

Coolant sensor problem.
Recently I've been getting the low engine coolant light. I took off the reservoir cover and it was low so I refilled it. About an hour later or so the light came back on, I checked the reservoir cover again and it had gone down some.
The next day I removed the cover with the engine completely cold and the reservoir was empty. I'm concerned that I may have a coolant leak, but I don't know where. There were no puddles under the car and the engine bay doesn't smell sweet when it's running either. I'm still unfamiliar with these vehicles though so any help is appreciated.

Is the same problem that is in the Coolant leak thread??
Hi
The photo in this thread is the same photo that is in the Coolant Leak thread I found posted Today at 12:13 pm.
I put the diagram and parts information with the Coolant Leak thread this morning. https://www.jaguarforums.com/forum/j...at-part-53997/
The Coolant sensor problem could be that the coolant sensor float is stuck at the bottom of the coolant expansion tank (reservior tank). I had the same problem after I had the cooling system flushed and refilled with new coolant. The check engine light came on, also the low coolant warning message.
When I checked the coolant level and it was a little low. I filled the coolant reservior tank to the top. But still was getting low coolant message. I called our mechanic and he said either the coolant sensor is stuck or it went bad.
I opened the cap of the reservior tank and stirred the coolant with an oversized round long handled plastic spoon. Apparently it must of moved the float of the sensor enough to unstick it, because the low coolant message went away and the check engine light is longer on.
Try it and see if it works for you also.
