On my 350, the original fan belt size was 45013/10A1145.

Because the crank pulley was making contact with the oem crossmember in the truck, I had to go with a smaller crank pulley. I basically need the next belt size down from 45013. Can anyone help me to determine what replacement belt that would be? It's a V belt.

Thanks!

Here's a trick I've been using for the past 60-something years to figure out non-standard belt sizes. Find a junk belt that's too long, and cut it. Wrap the belt around the pulleys with the adjustment slot almost, but not quite at its minimum point. Cut the excess belt off so the ends will butt at that point, drill a couple of holes and splice it together with a piece of mechanic's wire. (Baling wire to you farm boys!) Now, go to the local parts store, find the gray haired old guy who knows how to use a belt measuring tool (not the keyboard commando kid who's too busy texting and picking his nose to notice you're standing there) and buy the same size belt as your patched-together one.

I don't think that guy exists in our local shops anymore. Every time I go in now for something for a 350, I have to tell the doof behind the counter what year car it's from (even though it's not in that car anymore), and whether or not the car that it's not in anymore has AC and cruise control :laughs:

I always thought someone had played an April Fool's joke on them and super glued their elbows to the counter...
