Hi All,
I'm replacing the engine belts on my '66 Eldorado; it's an a/c non California car. The alternator drive belt had snapped so it seemed sensible to change everything else at the same time.
I ordered a replacement set from Caddy Daddy and have noticed that, in the case of the replacement belt for the a/c compressor drive, there is a significant difference in size from the belt already on the car.
My existing belt has a size code of 15560 with an outside circumference of around 56.7inches, and is routed to spool over both the water pump/fan pulley and crankcase pulleys as well as the compressor.
However the Caddy Daddy replacement (size code 7435) has an outside circumference of only 44 inches odd, and would I guess only spool over the front groove of the water pump/fan pulley, leaving the front groove of the crankcase pulley unused.
The Cadillac shop manual doesn't show belt routing or specify belt dimensions (as far as I can see), and Rock Auto list both the longer and shorter belt sizes for the '66 a/c compressor belt.
So which is the correct belt size and routing?
Also if anyone has experience with the different belt brands I'd very interested to hear.
Many thanks,
Robert Green
I spent weeks trying to find the "super special" unique extra wide A/C belt for a mid '70s Cadillac 500ci, because the typical .5" belts just isn't enough--allegedly.
Well I never found part numbers, I never found special dimensions, and as of now I'm going to run a Dayco 17625.
I think you may have a hard time finding these special "wide AC belts"
