What were your symptoms? My car is taking quite a while to warm up now , I'd say double the time it used to and I wonder if there is a problem on the way. It runs and drives perfectly and is using no more fuel than normal.

I've had coolant probs with my car. Its a 2002 1.4 8v and the temp gauge wasn't working right and the car was taking ages to heat up. Then I noticed a coolant leak on the front passenger side of the car. It turned out to be some sensor on the side of the radiator. I got it tightened up and I've been ok so far so maybe its worth checking that?
