Timing belt with Mac Pulleys

[SteedSam]

What size timing belt is required for a 1994 Mustang 3.8L with A/C and Mac underdrive pulley's? I had one on before and it just blew to smitherines a few minutes ago. I guess it wasn't the right size.

Your car doe's not have a timeing belt, it has a timeing chain, and the belt your talking about is the Surp or drive belt.

Serpetine (spelling?) belt is what you need, and to find out what kind call Mac.

Yes, I meant serpentine. Anyone know what size I need?

Looks like a 96" belt for use with the 25% Reduction Crank and Alternator Pulley. I think - I'm still looking into this...
