What size belt to bypass A/C


MAC

Recommended Posts

My a/c hub bearing (94 Eldorado) is about to give out and before it does I want to bypass the compressor to avoid damaging it. Does anyone know what size belt I can buy to temporarily avoid the compressor? I have the Northstar. The only thing that is obvious is that the belt will be quite a bit shorter. I searched the archives of the old forum but there was no information about what size belt can be used.

I would appreciate any assistance.

Not sure as to the size you could always take a tape measure or string and route it through the pullys and get a length for the belt you need.Then go to an auto parts and match one up The auto parts should have them listed by length.

Good Luck

Hey - did this same thing on my '93 4.9

Take a piece of string and go through the maze, bypassing the AC

It doesn't have to be EXACT - as the belt tensioner will pick up the slack, if there is any. Good luck

ACDelco 6K739 - 6 ribs, 73.9 inches in length - worked perfectly on a 1996 Concours last summer until the compressor could be fixed.

Thanks for the info. I used the number you gave me (ACDelco 6K739) to cross reference the same belt made by CarQuest (No. K060739). I put the belt on today and its works fine. Now, I can take my time replacing the hub bearing and I don't have to worry about the possibility of damaging my a/c compressor.

For some reason I am NOT able to post a link to a thread that discusses the by pass belt. A good thread on the by pass is this one, search for this in the subject line "AC Compressor, Did bearing kill seal"

I've been using a 73.9" belt for over two years. I need to get off my arse and get that compressor replaced.

Hey Ken,

Make a little trip down here to Texas in July or August..... 100 to 105 in the daytime (or more) and if you are really lucky... it "MAY" cool off to 80 at night.

You will get it fixed REAL QUICK. :D:D:D
