radiator cooling cfm requirement
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.94 sub 6inch lift 34inch bfg mt. massive rework project soon. the audio system hit 150.3db so now its time to rebuild and try for 155db. mudpuppy is also getting a new engine, rebuilt ifs, dual 500amp 15.1vdc alts, 5 5,000amp batts, ant the combined wattage with the new system should be close to 15,000watts. this is going to be a wild ride boy and girls.
