They show part NA for the Silverado. So then I went to Rockauto. I sure dont know why there are different numbers, it doesnt seem correct. Guess I will have to call in a favor at the local Chevy dealer to see if I can use the Tahoe compressor. One thing I didnt check is the number of grooves on the drive pulley. Think that there may be a difference? Sure hate to waste a brand new compressor, but I dont want to dig myself a hole either. Edited by george88gta on PM. Same part for either application as far as Delphi is concerned.
One with rear air and with Denso compressor, one without rear air and with Denso compressor, one with H6 HT6, etc. The physical appearance of the Denso vs. H6 style compressor is pretty significant, so that'd be a dead giveaway comparing the two you have there. Why some brands have a distinction for rear air and Delphi does not Went to Chevy this morning and gave them both vin 's. They verified that there are two different part numbers and they wouldnt recommend swapping them.
So I contacted the mfg of the compressor. So that is the plan. I am also trying to find out what type compressor I have in my truck. I need to know what type so I can buy a rebuild kit for it. It still works, but leaks from the big seals on the end. I used to rebuild transmissions, so I think I can handle this. If not, I will only be out the money for the kit. I am trying to find out what type compressor I have in my 97 Chevy diesel.
Yours originally came with a Harrison HT6, the top one in post 2. Thank you for the info, that is what mine looks like. I just wanted to be sure. Pay extra attention to the case seal, oil it up good when installing it. No doubts at all. Edited July 6, by barry G. Jsdirt 1, Posted July 6, Edited July 6, by Jsdirt. Posted July 6, Posted July 8, I made a couple of phone calls and checked The ACDelco evaporator core is manufactured in Taiwan.
The Four Seasons evaporator core is manufactured in China. Jsdirt 1, Posted July 8, I agree with you there. Can't get away from it these days. Quality is hard to find. Posted July 12, I bought all the other parts I need at O'Reilly's today. Thanks to everybody for the help. Jsdirt 1, Posted July 12, Posted July 12, edited.

If it does you will have to replace them. If you are installing a new compressor and it has oil in it already from the factory, turn the compressor up on its face for about 5 minutes — no more than that. The oil in the compressor will lube the front seal when turned up like that, but if you leave it like that, the oil will lock up the compressor because oil will leak into the cylinders past the piston rings. So, only put it on its face for 5 minutes before installing it.
You should do this for a compressor if you rebuild your own. Check the fit of the compressor onto the bracket before you install it. If the bracket is uneven two piece brackets have this tendency , the compressor will rock in place. SO, test fit it before you stick it in place for the last time. The torque settings on the bolts that hold the compressor in place are 37 ft lbs 50 nm. There are AC line flushing compounds that you can get at the parts store in an aerosol can. IF you are going to go to the trouble of replacing most of the parts, you should put a vacuum on the high and low sides of the system, to insure that there is no moisture or any other compounds in the lines.
You put a vacuum on it and draw the system down, then shut off the valves to the low and high sides and watch the gauges for at least 10 minutes. Your manifold gauges should read 0 on the high side and at least -. You can get AC manifold gauges at Harbor Freight. You can also get the vacuum pump there if you want. For the trucks, the regular cab trucks use 32oz of Ra, and the crew cab trucks use 36oz of Ra. IF you have an extended cab use the figure for a single cab.
Both systems use a TOTAL of 8 oz of oil — this is a pretty common oil requirement on most of the systems made before , so most of the oil you will find in the parts stores will come in 8 oz bottles.
