Where/What to buy? A/C compressor for 95 TAhoe GM 1134343

A/C compressor for 95 TAhoe 6.5 TD GM part number 1134343

Where is the best place to buy a replacement?

What is the best to buy for a replacement?

We will probably have this vehicle til it rots away to nothing. We are on our 3rd compressor. The previous replacements were new AC Delco's.

All the recomended procedures were taken when changing the parts.

Are these compressors more prone to failure than others?

This compressor is leaking around the seals fron & back.

The Tahoe now has about 245,000 miles. The OEM compressor lasted over 100,000 miles. So we've gone through 3 in 140,000 miles or so.

maybe Delphi? otherwise ACDelco is the way togo

It's time to step back and look at more than just the compressor. For example, was the system thoroughly flushed and was the proper amount of oil added? Were other things replaced or tended to like they should for example the receiver/dryer or the orifice tube?

When a wired device burns up, it introduces acid into the system. If this acid is not dealt with properly, it will severely shorten the life of the replacement.

What about those items that at first glance don't appear to have an influence on the AC but do. Take for example the serpentine belt and it's tensioner. I've seen many a tensioner that was not smooth, make little jerky motions on the belt that over time wiped out the compressor. While it does put a lot of stress on the clutch. Once the clutch is engaged, it transmits into the compressor shaft. I always suggest changing the tensioner and idler pulley when changing the belt for just that reason. Not to mention the squeal that they make.

A bad tensioner will incidentally wipe out alternator bearings pretty quickly. Just FYI not related to the AC issue.

We by chance did change the tensioner last fall. So that could have been a problem

Thanks

Of all the items I listed that need attention, you're focusing on the one that you did?????? What's the catch?????

What about testing for the presence of acid and dealing with it if you found it?

Flushing? Which doesn't completely deal with acid BTW.

A replaced filter/dryer?

Proper amount of oil?

Refer to post #1
"All the recomended procedures were taken when changing the parts."

Which in my mind would include:
Flushing? Which doesn't completely deal with acid BTW. Didn't know that. I need to learn more about this.

A replaced filter/dryer?

Proper amount of oil?

I guess I should have spelled that out. The tensioner was the only item we did that was not covered by the first statement.

I have a card for it, but it's been years since I did any A/C work. I don't even know where my gauges are. Consequently I have to hire everything done.

What does one do to correct the level of acidity. I thought pulling a vaccum and reloading the system properly would set the acidity level.
