Ok on the OBS chevy's for whom is doing like an lq4 swap. I understand the problem with the a/c bracket, it brings the compressor too low and have to notch frame. But why do you need a special compressor, why not just use the one that came with the truck? Like mine is a 98 c1500 but my harness is a 01 silverado and an 04 lq4. So why can't I use the 01 silverado a/c comprssor and a reworked bracket, or can I?
Are you using the truck water pump? Are you using a drive by wire throttle body? I believe, but am not positive, that both of these will interfere with most passenger side high mounted a/c brackets, no matter what compressor you use. Someone else might know better than I do though.
Also, since the truck A/C compressor uses a narrower belt & pulley, your going to have to buy & install a wider ribbed pulley. Have no idea where you would buy one, or how much it would cost, or even "if" one exists. Never seen it done.
It is the truck water pump, and the drive by cable. So why can't I just use the full setup out of the donor truck?
You can if you clearance the frame enough for the compressor and fittings & lines. You can bolt in a complete truck engine as-is, after you do that. I misunderstood you. I thought you wanted to use the truck compressor up high on the passenger side. Or if you want to try and make brackets that will hold your trucks original compressor down low, you can try and figure that out. But I don't know of anyone thats done that. It might also need to be mounted upright, in its original orientation, due to lubrication needs...I don't know.Originally Posted by Pavetim
