What are the correct belts ?

[Danny W.]

Gentlemen,
I can't find what the correct original belt numbers are for my 69 427 / 435 .
- power steering
- fan
- alternator
Where can I find this information ? Any assistance greatly appreciated.
Thanks,
Danny

waterpump/crank (fan)= GM #3952336

waterpump/crank/ps pump (power steering pump drive) = GM #3940992

p/s pump/alternator (alternator drive)= GM #3878243


All of the above are long-since GM discontinued. However, you can get them in reproduction.

I bought belts for my 1972 from Quanta Products and I am very happy with their appearance, functionality and overall quality. On top of that, they judge well.

Quanta belts went on my '67 in Dec. 1993 and they're still running fine without cracks or much wear. Of course, I only have a little over 1000 miles on it since full restoration.

They look good, and probably judge well, too, but.
I either "threw" or broke my (new) Quanta fan belt during one particularly "spirited" driving session with my Corvette. My engine was factory equipped with the deep groove pulleys, and still wears them.
The Quanta replacement has been in use for the last 2 years with no probs.
