We have a 97 Jeep Wrangler that I have serviced regularly since I purchased new. It only has 97,000 mile since my wife and children drove it locally. During winter, the Jeep drives fine. As the weather warms up and especially when using the air conditioning system, the engine heats up within 10 to 15 minutes of driving. Once, when my daughter was driving in warm Spring weather, the Jeep engine seized up on a highway. We had it towed and the dealership flushed the coolant and it drove OK for a few days. We have noticed that the coolant is burning up in Spring and Summer needing replenishment frequently. We also had the thermostat, water pump, belts, and hoses replaced. The overheating problem (needle moves to red zone) still persists in Spring and Summer. If we switch off the A/C, the vehicle drives OK for about a 1/2 hour but Atlanta summer can be brutal without A/C.
Except for this issue, the vehicle is well maintained and in fact every time I get the oil changed, the mechanics ask if I would sell the vehicle as it is in such great shape.
Please help. Thanks.
