I'm considering eliminating my A/C compressor to "clean up" my engine bay. I'm finding two(2) different Dorman part numbers for their A/C delete bypass pulley. Both "say" they fit V-8 LT1 engines, but they look VERY different in photo's???

I'm finding Dorman 34209 and Dorman 2100052 bypass pulley part numbers, both showing that they fit '97 LT1 engines?

Has anyone already done this, and, if so ........... what bypass pulley part number did you use?

TIA for all reply's.

 

This is the GM part #. See if they can cross-reference it.

10115875

That's what I used, but I think the GM part is discontinued.

 

One of those might be just the pulley, instead of the whole thing. The GM part number still looks serviced.

 

I bought mine off of the for sale section on here. That way I knew it was already the right one....

 

I just took delivery of the GM part last week from Jason Cromer of Sam Taylor Buick/Cadillac of FL. Part was on back order and took about 3 weeks to obtain. $70 shipped. The Dorman part needs to be modified (drill out the threaded mounting holes) and shimmed to properly locate it. I have one that's already been drilled out (brand new) if you're interested (PM me). It takes the standard belt size.

 

Just looked at http://www.dormanproducts.com/p-6944...ymmeid=6248401

Only showed 34209 ???

i searched injuneers part number and it cross referenced to dormans 31455

 

That number according to Dorman is for 93 thru 95... 96 and 97 uses the number I provided...

The pulleys are different...

 

First of all ....... Thanks! to all who replied. That's what makes this board GREAT ...... people willing to help other people out.

Secondly, for all those people who may find this thread sometime in the future by using the search feature ........ what a difference in price this item currently has.

Because of the information you have all supplied me from the above posts, yes, you can still get the original GM bypass pulley P/N 10115875 from Summit for $92.99 plus S/H. Or, you can get the Dorman P/N 34209 aftermarket pulley from RockAuto for $20.79 plus S/H, and the Dorman piece ........ comes with a "Lifetime" warranty!

Now the question bears asking ...... can there really be a four fold improvement in quality, (to justify the difference in price), for an item as simple as a pulley and bearing assembly???

Thanks, once again, to all who replied, I think I know which way I'm going to go with this.

 

I do know that the Chinese knock-offs of the GM part have a poor track record as far as the pulley freezing up and some require shimming to even fit correctly (been mentioned above).

 

TPIS has them..

 

I would like to delete my AC on my 96 as well. Besides installing the pulley bypass is there anything else you need to do? Anything with the PCM? TIA for any help on this

 

Nothing else to do.
