i have a 2000 XJ with 101K mi. Ive had on and off overheating problems for the past 18 months, especially when idleing in traffic in the summer. So far the dealership has blamed the problem on and replaced the: radiator, water pump, t-stat, t-stat housing, and radiator cap. And the systems has been flushed a few times as well.
It has been running fine untill a few days ago when it got a little hotter than normal, but not into the red. I figured it was finally time to give that watter wetter a try. So i went out and bought a bottle. When i poured it in, i noticed that the overflow resivoir was filled up past the full level, and that the radiator wasnt full. I ended up pouring in 1/2 gallon of distilled water before the radiator was full. I drove it around for a day and checked the levels again. The radiator needed anohther quart or so of water and the overflow bottle was fuller than last time.
Anyone have any ideas as to what is going on. Only thing i can think of is that the coolent expands and goes into the resivoir, but then when it cools off, it doesnt make it back into the radiator for some reason. Another concusion that I have painfully come to is that the head gasket is on its way out, allowing gasses from the combustion chamber into the coolent. Any ideas on why the overflow bottle keeps filling up and the radiator keeps losing fluid?
