I went mudding in my jeep. It was really soupy and coated the entire engine bay including the rad. Didn't wash off the mud and then drove downhill into town a few days later Didn't realize temps until the return uphill trip. Temps pegged the gauge just below 260F for a solid hour. I smell a strange synthetic smell now in the engine bay near my AC components but another than that the engine runs fine. Its a straight 6 inline engine with about 190K miles on it. Does that sounds like an AC leak? Should I be worried about other components? There is no smoke coming from the engine or the tail pipe so I think my head is good.
