Neal, when you get your Magnacharger, you might find the alternator pulley works pretty well. By using the alternator pulley, you have more room to work on the belt without touching anything else on the truck. I regularly changed my pullies this way with all the hoses in place (upper radiator and intercooler). I would also recommend doing this with the engine cold.

 

HI!... FLATSMAN : It might be useful with a MAGNACHARGER kit but I'm still N/A and that's the easiest way I have found to do belt changes. Espiecally since I'm running a 1" shorter than stock belt. I won't be running the same set up as you anyways when it comes to running a MAGNACHARGER on my truck. My alternator will be relocated to where my A/C compressor used to be.
