Re: Radiator question

.

Last summer I solved my idle temp creep. In my case it was an airflow problem.

The solution for me was to replace my dual electric fans with spal fans that actually move air. The two 14" fans I had been running were cheap generic 40 dollar fans off eBay that I purchased from Champion radiator with them saying it would cool up to 500 HP or whatever. Those fans were a ripoff.

I had my Copper/Brass 4 core original radiator rodded/repaired and with it all back together with the spal fans and a 190 degree thermostat, all is well in summer idling. At speed the temps hover below the the threshold of fan activation (190). At idle the fans will cycle on/off keeping the temps below 200. I have the system wired to activate one of the dual 14" spals and a pusher fan on my condenser whenever the A/C clutch is engaged. Otherwise, one fan activates at 190 and the second activates at 195.

Before these changes, I had to turn off the A/C at stop lights sometimes to stop the heat creep.


Hth,
