Hi,

I'm not sure of the exact length needed, but you can measure it to make that determination. The easiest thing to use is a cloth tape measurer. The kind people use when sewing.

Take the tape measurer and route it through all of the components being used and bypass the AC compressor.

Since there will be no tension on the belt tensioner when you do this, subtract an inch from the total you measured.

If you take the measurement to a parts store, they can get one for you. Take your old one as well so they see how many ribs it has.

Is the compressor clutch locked at all times?

let me know.

PS: I looked up belt routing for this vehicle. The alternator and compressor are the only two things shown, other than the belt tensioner and crankshaft pulley.

I copied what I found and highlighted where I think it would work for you. It's not going to be a very long belt. LOL
