Am I rememberring correctly?
A freind had a fully loaded '72 Vista Cruiser with pwr windows, etc. and a 455. I would bet money the A/C compressor had twin fan belts to it. So, I wonder why the '72 Toronado 455 A/C compressor has one belt? Does anybody here have a '72 455 with twin belts on the compressor?

I looked in my GM parts catalog pulleys and belts section and it doesn't show show dual belts for AC compressors on the Toronado or Vista Cruiser/Cutlass in '72.
Actually I didnt see any dual belt compressors for any Oldsmobile, from '70-'75 at least. Allan |

Didn't the later cars have a dual pulley on the AC compressor so they could run an additional belt for the smog pump? I thought that was in the late 70s though...

With the amount of torque needed to drive the A6 compressor, two belts should have been standard on all models to reduce belt stretching.
I have noticed that if the A/C belt is not gorilla-tight, the bottom of the belt flaps a lot and was actually cutting through the lower radiator hose. My '86 has a similar problem, but not as bad. Of course it has the R4 compressor... The cheesy cogged belts stretch even more, making the problem worse. Anyone know where i can get a non-cogged variety? All the big local chain stores only carry the cogged ones for 1972...
