It wasn't worrying me much till yesterday. I got caught on the I-10 at 3o'clock and bumper to bumper traffic because of an accident. It didn't overheat but the temp got right up to the white line before the red area. The a/c shut itself down untill the engine temp came down far enough to cycle back on. It did that the whole 1.5 hrs of stop and go. The motor didn't bubble over though.
