The high speed radiator fan comes on before I expect it when I am stopped in traffic. This can occur well before the needle hits the LED. The system will run with needle in the middle of the LED on warm days, so I think the gauge is good. I have replaced the fan switch and it acts the same.
I have a bleeder valve on the radiator, with a tube into a jug of water. The system doesn't push air out, just coolant.
So I am asking if the radiator itself can go bad in some way where the fan switch sees hotter temps than the circulating coolant? I didn't think the radiator would trap air any place except at the top. And then. it doesn't happen all the time.
Thanks for any help.
