My low coolant light has been coming on when I have the a.c. on and I'm going down the highway. I have checked the coolant level many times, it is above the full line. Has anyone encountered this? The car isn't getting hot or anything, just the light comes on.

 

Yes.


If you do a google search with site:rx8club.com coolant light returns many threads discussing this very common problem.

 

Here's all about it.......all the answers are here just do a little searching....
