Re: Radiator fan help..electrical aspect

Hello friends...yes I am still alive and yes after 2 + years STILL chasing my overheat at highway speeds overheat issue. After changing ALL coolant components down to clamps, still was happening. Long story short found short lower rad hose was kinked in half, fixed that ( was due to t stat housing being in a position to kink hose since it was pushed out due to remote oil cooler lines in the way) Anyho, got it fixed, system burped, went for first test ride in 3 years, car ran perfect, temp never went over 181 ( as part of heat issue, lo speed fan on at 176, high 181). Today, went out for an hour, highway and traffic, car stayed at 179, even stopped for 15 minutes idling car stayed at 176. Out of nowhere on way home, temp started climbing, got home was 230 and fan was off. I hooked up handheld and when I reloaded tune, fan came on. With car running, turned on AC, no fan. I let the car cool to 170, started her up, at 176 lo speed came on, I turned on AC and high speed came on. Car stayed at 181 for about 15-20 minutes and out of nowhere fan cut off, temp started climbing and at 203 I shut it off.So in summary, when car is cool and started, fan will work correctly, but at a certain point just shuts off and will not work again till car cools down.Do you think resistor or fan motor overheating? Fan installed 2017 and says made in freakin Thailand. Opinions or ideas? I was so excited to be letdown AGAIN and yes for you old members, my bad luck is still around. Sorry away so long, life, cancer, retirement, you know the drill, but I'm back lol.Thanks
