Well, I am trying to do some things to improve the ac performace in my truck. I have read several threads that mention installing a pusher fan in front of the AC condensor. My truck's ac does okay but nor great (at 85°, duct temps will get down to about 65°) running down the highway, but as soon as I am down to 25mph in town (or sitting in traffic UGH!) the temps climb rapidly. I am thinking a pusher fan may help that situation. I know others have done this, but what is a good brand and model of fan to use? Can I just mount it directly to the condensor with the "zip tie" type kits, or would it be better to fab up some mounts to the radiator support? I know I will need a relay, and was thinking of triggering it when the system is set to MAX AC. I don't want to trigger ot off the compressor as it seems like the compressor runs all the time with the AC on. I should mention that me truck as "dealer installed" ac with a Seltec compressor and a parallel flow condensor and is not the Ford system. I had the system evac'd, leak checked and new oil and refrigerant put in (and the shop says it is as "good as it is gonna get") It has an expansion valve in front of the evaporator and a filter/drier mounted in front by the condensor. I have some aluminum faced foam insualtion ordered for the evap housing too. Thanks for any suggestions!
