This is about a 2008 Torrent SUV. About a week ago my self and 3 friends were sitting outside Jack in a Box eatting. The motor was going and the A/C was on. All of a sudden the overheating bell started sounding. I turned the motor off, turned the A/C off, rolled the windows down . There was a puddle of antifreeze on the ground. I filled the over flow tank with water, I always keep a gl jug of water in the back of the rig, old habit. I got the rig home. I though I just wasn't watching the antifreeze level very good. Today my self and my room mate had things to do. The A/C was on today and the overheat bell started sounding on the frwy. I pulled over to the shoulder to let it cool off. Going across town and back with the A/C off. We had to stop many times to put water in. The overflow tank looks older then Mount Rushmore. It is dirty, the inside walls are full of crude. The cooling system has run with no problems for as long as I have had the SUV, about 2 to 3 years. There is a small leak on the ground. And at the Rite Aid stop I heard a steam type hissing on the right side of the engine block. Between the engine block and the over flow tank. I have been looking into a problem with no cabin heat. To that end I had the heater core blown out and the thermostat changed. I think the temperature door in the dash is stuck in the A/C side. But now I have a bigger problem then no cabin heat. Any ideas?
