So if your luck is anything like mine, your A/C clutch goes out at the most inoppurtune time; like Thanksgiving Eve. When the clutch bearing goes out, the belt will no longer turn freely, thus rendering your Dime useless. After searching and finding no A/C bypass information on the forums, I found my own solution. Hopefully this will help some other dime drivers out there.
This was tested on a 2001 Jimmy 4.3L with the stock CS130D alternator. This should work on all 2nd Generation 4.3L motors.
You will need a 6 rib, 84 inch belt, here are some part numbers:
NAPA- NBH 25-060840 or PBH 6K840
Advance Auto- Dayco 5060840
Carquest- K060840 or K8406
This belt is fairly common, appearing on 2005 and up F150s with 4.6l & 5.4l motors; Chargers, 300's & Magnums with the 2.7l V6, and the 2.0l Focus from 05-07.
Step 1: Remove the idler pulley.
Step 2: Route the belt around the crank & water pump normally. The belt will go straight from the power steering pump to the alternator, bypassing the A/C and idler pulley. You WILL need to pull the tensioner back as far as it will go: the belt will stretch a little after a day or two.
Step 3: You're done!
Now, with the stock alternator, do NOT use an 85 inch belt. It slips and doesn't provide enough power to the accessories. I imagine you would need the 85 inch if you have done the AD244 alternator conversion however. I didn't do the conversion until after I fixed the A/C, so I can't verify that it would work. If anyone can verify, shoot me a PM, and I'll update this.
