    heya all. i have a 94 suburban k1500. originally it had a mechanical fan. i replaced that with a heavy duty electric fan for a f350. well after many years now on a used fan to begin with it finally went bad. i intend to set up a duel 16inch fan system. 1 slower fan for normal usage and a high flow fan for a/c, towing ext. now my question is: how much cfm is required by factory specs for the k1500 with a 185 thermostat?

    im needing the normal run time cfm specs to ensure i get a fast enough slower fan for the cooling system. any help or info with this would be greatly appreciated.

    nevermind. i just decided to get 2 16inch fans. im going to run one for normal all time use and the other for a/c and manual override for towing.

    ill have to build a shroud but thats really not hard to do.
