GM AC compressor identification and reseal?
 

'97 Suburban 6.5 turbodiesel - AC system has leaks so it was charged with dye. Months later dye is collecting on the case of the compressor -

The clutch and tail ends and hose fittings show no dye.

Questions:

1) What compressor is this? It has an OE looking Delphi label and an uneducated internet search suggests it's an H6 compressor rather than a Sanden.

2) Where could it be leaking from? Although there's a step in the case casting, I don't see information on separating the forward and aft sections of the case.

3) Is it worth resealing the compressor or is $200-250 for a rebuilt compressor money well spent?

Thanks,

My advise is to replace it with a NEW unit. Had nothing but bad luck with remans.

I've sold thousands of reman ac pumps, and hundreds of new ac pumps. I seemed to remember the new pumps coming back more often then the reman ones, due to a lower volume of new ones being made, and them sitting on the shelf longer.

Biggest thing I can say as a former parts guy, flush the condenser, then replace the orriface tube and drier. Lube the o-rings with pag oil (should be pag 150 iirc) when you re-assemble it.

biggest reason i can see is due to improper lubrication procedures. BTW parallel flow condensors are nearly impossible to properly flush. some manufacturers will not honor warranties unless the condensor is replaced along with the orfice tube and accumulator/ receiver dryer. its possible the housing is cracked. its recommended to torque that style compressor with a torque wrench when installing it.

heres the o-tube out of one i did recently. you would never get that stuff flushed out of a parallel flow condensor. the older tube and fin are easily flushed.
