[QUOTE="notagt, post: 16597264, member: 176670"] I have been fighting an overheat issue for 2 + years when car is driving down the highway. FINALLY tracked it to a kinked lower rad hose. Fixed and burped. Took one test ride for 20 miles..did perfect, stayed between 179 and 181. I went out today, again car did great, traffic, no issue, stopped for 20 minutes, car stayed at 176 ( as a note, as part of my chasing issue, lo speed on at 176, high at 182), even dipping to 174 where fan turned off. Out of nowhere, temp started climbing, hit 230 and I shut it down. I noticed with handheld sct redownloaded tune and fan came on, but cranked car, fan would start to turn and stop. Once car cooled down good, started and low fan came on as it should. Turned on AC and fan went to high speed and temp stayed at 179 to 181. After about 15 to 20 minutes with car running and AC on, fan suddenly stopped and never came back on, finally at 203 and climbing, I just shut her down. So it seems once car cool, fan will work correctly in lo/hi, but after a bit of time just shuts off and fan motor seems hot but hard to tell. Do you guys think I need a whole new fan or maybe a new resistor? Sorry for length of post, wanted it to be precise of what's going on. Thanks. [/QUOTE]
