I wish to bypass my locked-up A/C compressor in my 2003 GT by using a shorter serpentine belt in place of the OEM belt, as shown in this You Tube video: The belt needs to have an O.C. (outer circumference) of 81.5" as noted in the video. However, it fails to state a manufacturer and part number for the belt. Has anyone ever ever performed this fix who can provide the belt's manufacturer and part number? I just sent an email to Gates customer service, but don't expect a response for a day or two.

I am aware that an adapter is available that replaces the A/C compressor with a pulley that matches the compressor clutch pulley, but I don't want to go there as I need to keep the A/C system intact until I can have the compressor replaced, system flushed, new receiver/drier and orifice tube and system recharge sometime this winter when I have more time and hopefully a few more coins in my pocket.

TIA to anyone who can provide some useful info.

 

Just punch in what you need. I don't personally care for dayco but they at least have an easy to use tool...

Mustang_Don, LMR sells a A/C Bypass pulley. Part #LRS-19216B for $47.99. Most of the people I have asked have stated your belt length should be 70.5 inches. I am not certain about the belt length, but it sounds right to me. Good luck with this project.

 

He did say he got a "Daytona" belt.

He just didn't say the part number.

I did a search on, YAHOO, on: 81.5" Serpentine Belt and what do you know, all kinds
of part numbers... Duralast 815K6 was the very first result, amazing.... Effective Length (in):81.5

815K6 - K-Section Micro Rib Belt - Length: 81.5" - 6-rib

• Dayco - 5060815
• Gates - K060815
• Goodyear - 4060815
• Napa - 25060815
Search Engines are just, I mean, wow, Amazing...

 

I received the email response from Gates customer service within an hour or so after sending them my query - surprise, surprise!
Anyway, their response was a belt selection chart that included just the belt that I appear to need, PN: K060810. It is 81-5/8" O.C.,which I hope will fit just fine. My local auto parts store has it in stock, I intend to pick it up tomorrow morning and try it on for size.

Thanks to everyone for your responses.

 

Gates - K060815, which I have listed, is the 81.5"size mentioned in the video
Your part# is 81.608"

The tensioner will allow for some margin, just not a whole lot so it doesn't
flop over to the other side and the belt fly off. I would rather be on the
tighter side than looser, as the belt will stretch out when it gets hot.

 

Mustang_Don, sorry about my misinformation. This is a good reason this Forum is so helpful. There is always someone there to catch your back.

 

MustangDude, the part # K060815 is 82.105" O.C. The 81.5" you state is the Effective Length. Problem is, I'm not sure which length was actually measured in the video. Hopefully, as you suggest being a little on the tighter side may be a good thing in this case, since the tensioner will be exerting less tension on the belt due to the reduced mechanical advantage if I am envisioning the installation correctly. If the belt I'm getting doesn't fit properly, I can always take it pack to the parts store and exchange it (I hope).

 

NEWS FLASH: I attempted the fix shown in the video in my initial post, and apparently the guy who made the You Tube vid and posted it did so before attempting the mod himself. Truth be told, this mod doesn't work! I picked up the recommended belt this afternoon and when I installed it discovered that it was too long. Unfortunately, that was not the only problem = I determined that a shorter belt would not resolve the fix, since the belt tensioner would not be functional with a belt that bypasses the A/C compressor. The geometry of the completed installation, primarily the arc the tensioner moves when functioning with the OEM belt and compressor will not apply any tension to the serpentine belt when the "fix" is attempted. My solution is a relatively easy one. I already have a new compressor and OEM belt in my man cave, so I will just get some assistance to replace them without getting the A/C functional again for another two or three months, a winter project.All I will need is a new receiver/drier and orifice tube and the necessary funds in my hip pocket to have the proper fix completed and once again have A/C that works. I will see if the auto parts store will let me get the A/C system flush in exchange for the belt that I take back to the store tomorrow. That will be one step forward, wish me luck. The only good thing that I had going today was the meatloaf that I made turned out to be delicious!
