I just got done installing a new aftermarket aluminum core radiator and while I did that I decided to put in a 14" hayden slim fan. I directly bolted the fan to the radiator in the same place as the stock fan. I also added some redline water wetter, flushed the cooling system and added all new 50/50 coolant mix. I bled the system and then went out and for a drive.
As I sat at a light waiting my coolant temp reached 225 degree mark and I promptly headed home. As I drove the temps dropped quickly. I thought maybe the fan wasn't kicking on. Well it was. I wired the resistor out so the fan only runs on high. I have a new thermostat too. Still have the same at idle overheat issue. To me 215 is too much. While it's overheating I can raise idle and the temp will still not lower. Water pump does only have 15k miles on it, so does the engine.
I still have A/C and a stock intercooler and piping. Prior to the radiator/fan swap I never saw over 205 at idle. I reused the same coolant switch.
Has anyone else had a similar issue?
Any ideas?
Thanks
