I've found pictures, of two different possible routing of the A/C belt.
One drives off the fan hub alone, and moving the compressor adjusts tension , second drives from the fan hub and has secondary tensioner.
Important to know which one you have before tensioning/checking belt.
The picture with the short belt ( red engine A/c compressor out of frame to top right) belt defection at center between pulleys would be 1/2" , the second, on the long run of the belt would be 3/4"
Still looking for the diagram.
Easy to see why side rad is preferred.
