Default Re: “Correct” fan belt doesn’t fit

With your engine exposed like this you can pretty easily figure out the belt length that you need.

- Make a mark on your crank pulley and the belt in the straight down position
- Hold the belt in place there
- Pull the belt over the generator pulley, straight up position and make another mark
- Take the belt off, measure between your marks and double the value
- Look for the next longer belt but shoot for around maybe 1" or 1-1/2" longer
