Title: eletric fans
Post by: sphnyx991 on January 11, 2011, 09:39:11 pm

is any body running electric fans on their trucks? what fans would be sufficent for 1984 k20 with a 350? i was looking at dual 12in fans that flowed around 2100cfm, would this be enough for around town driving and free way driving? would it be better to get a puller or pusher style fan? thanks

I have a single 16" procomp fan, flows 2000cfm on my 350 and it will cool that thing down fast.  If you have an aluminum radiator a single 12 would do ya.  I mounted mine as a puller.

I'm running a 2row welded aluminum radiator with dual 14in electric fans and its more than enough.

thanks for the replys. as far as wiring these can i just get a couple relays and and on and off flip switch to operate instead of a thermostat controlled switch?

Advance has in stock a $20 adjustable thermostat kit, I would Highly recommend it, you never know when you'll forget to turn em on and overheat.
