1998 Suburban K2500 6.5 td
I replaced every single part of the AC system this winter (except manifold lines on top of compressor - part unavailable).
New parts:
Delphi Ht6 compressor
Front and rear evap cores
Denson condensor (~15"x30"x1.25")
Ac Delco drier
New rear lines, (ac auto solutions off ebay -rubber lines).
New head unit, aka climate control module
Expansion valve and orifice tube.
Rebuilt havac boxes, New heater cores, fixed actuators, new blend door flappers.
Original Goal was to have ice cold AC by Summer. Right now it's 100 daytime high and AC performance is underwhelming.
Long story short, I have on order a few different larger condensers (other gmt400 c/k suburban applications), a couple different orifice tube, thermometer for vent testing, high pressure valve, low pressure schrader valve, etc., but I can't determine which upgraded four seasons 210cc compressor to go with...
1) Stock pulley size or Undersize, van application?
I AM GOING ALL IN. I want cold AC. I am ordering all the parts and preparing to have ducks in a row for ANOTHER* evacuation and refill (luckily my neighbor has a Profesional machine (robinair?) And diesnt charge much). Just learned from other recent ac threads of the larger displacement compressors.
Next on the list Compressor.
*I did the double up on orifice tube thing. Didn't pull the one out of the new condensor before installing, so that required a suck down/ refill to remedy.
2) going to have multiple condensers on hand for this next go around of cracked open systems work. Have a larger 35x18"x1.5" on the way, (OSC 4544?).
It just seams obvious that a suburban with front and rear AC should have a larger compressor and condensor, any reason why they would not have?
