    I noticed that my temp guage was heading into the red zone going up a steep hill. I was able to get the car to a Mc Donalds and had it towed to my Jag dealer. The problem was a stuck, partialley closed, theromstat which they replaced. I also had them replace the water pump with the new metal style. I am now seeing the ABS error light come on intermittently. Not sure what to do about that. The dealer checked the car and cleaned the ABS sensor plug contacts on the right rear wheel, which seemed to cure the problem for a few months,but the problem is back.
