That is something that you can try and experiment with, but I don't know if I would want to rely on the aux as my only cooling option. With your new switch it may work out just fine. I don't recall if those motors on that fan were designed to run at a more continuous operation, and I would imagine that the relay "gwank" suggested would help protect it......

I'm running a single 16'' Spal with the stock shroud. it works fine 90% of the time. However, if it is extremely hot out and I'm using the A/C, the temp creeps up at idle. I'm eventually going to go to the dual 11'' spal setup

no, I used brackets to mount it onto the radiator itself, but it sits in the same exact spot as the original AUX fan. I was going to try using just the AUX fan on a relay, but since it was so old I didn't trust it as my only cooling option

BTW, how much were they creeping up, I'm assuming you still have the CC aux fan temp switch in, did you reconnect it?

Glad you put it back in, or go to an electric unit as suggested by other members. Is your system working properly? Are your temps at the levels you expect them to be?
