I have had my 2005 XK8 for about 6 weeks now. This morning the Low Engine Coolant light came on for about 10 - 15 seconds and then went off. I watched the temperature guage and it is solid at the halfway mark and hasn't changed a bit.
Was that a warning that I need to add some coolant, or that it may be getting low? Or would the warning have stayed on if more coolant is needed?
Any recommendations on which type to use? Do you know what they use at the dealerships?
Without being silly, I'd say have a look in the expansion tank!
The temperature gauge is non linear and by the time it's got into the red so has your bank balance.
If the level is low check the hoses
There are two problems with the expansion tank- the tank can split and the level sensor can stick.
Both are covered in either this forum or XK8/XKR.
Don't do nothing, it needs sorting.

The sensor is very high in the neck, so if you are just a little bit low and the sensor is exposed, it will signal coolant low warning. Then warning will disappear when submerged. Usually adding a very liitle bit of coolant, like a cup or two will eliminate warning. You shoild, however, have pressure test to make sure there is no real leak. I am having one done today as i can smell a leak even though there is no dripping under the car. I am losing about a cup of coolant every couple of weeks triggering warning light.
