Hello,
I'm putting together a 1979 D200, and I'm swapping in a 318 from a truck that has factory A/C. From what research I've done, part of the A/C package included a "improved cooling" package which looks like consisted of a larger radiator, clutch fan, shroud, and different pulley ratio. My D200 does not have A/C, but I'd like to retain the improved cooling. The issue is that since the alternator and compressor are driven by belts off of the crank pulley, without the compressor I think I'd need an idler pulley where the compressor used to be to keep the current pulley arrangement. Another option would be to source non-A/C pulleys but I'd like to get more info before buying parts. The pictures attached show the 318 A/C belt drive and another 318 that appears to have an idler where the compressor would sit.
