Hello. I thank you in advance for your time. Here is the dilemma: The beautiful lady-friend has an '88 GL wagon. As of late, the temperature gauge is floating just below or just inside the much feared "orange zone". Facts as I see them that might be relevant: 1. About two months ago there were drops of coolant on our driveway. I searched all over--hoses, radiator, etc--but was unable to locate the leak. There has been no evidence of this leak since that time, though the issue with the engine temperature started soon afterward. 2. When the vehicle is run with the heat on full-bore, the temperature gauge tends to go down. 3. We live in Alaska and the car is kept outside in very cold temperatures. (I am not sure how relevant this fact is.) Recommendations I have already received and am looking to narrow down: 1. change the thermostat 2. change the water pump 3. change the head gasket 4. flush the radiator 5. pull the car in a garage, allow it to warm-up, and any ice in the radiator will melt 6. replace/flush the radiator 7. any combination of the afore-mentioned recommendations. Any light that can be shed upon the situation would be greatly appreciated. Again, thank you for your time. Josh
