Like for my car. Kinabit pang PAJERO na compressor. But I feel, di na ganong kalamig as before. I think iba ang specifications and hindi talaga designed for my car's engine and ngayon, nag overheat na pag naka on ang aircon.
I don't know, but OEM Mercedes Benz compressors are so expensive, we just slap on Sandens. Only the necessary fittings and brackets are changed. They work well enough considering the variety of systems they are fitted onto. The W123 has an aftermarket a/c, the W124 has the EUDM manual system, the W126 has the USDM automatic climate control.

Not sure about specific pressure settings. A/c' generally work between not less than 40 and not more than 200. Sorry for the vague description. Not an a/c tech here.

Btw, I'm running a higher capacity DENSO compressor on my system now. Not exactly a conversion. Just picked up a later model compressor. The mounting bolts are aligned. Only had to do minor mods on the pulley. I'm not expecting it to cool like when the car was brand new (considering the other components have aged also) but I'm surprised as to how well it works.
