serpentine belt R/R question and PS Pump R/R
Ok so I have replaced numerous Belts on M112 and M113 n/A motors. But never a K motor. So I know the basic process and the DIY that is out there is basically the steps I was expecting. My problem is my forearms are too big to allow me to reach down to the tensioner. the Supercharger Pulley and Supercharger idler pinch my arm tightly agains the fan assembly. Can it be done from underneath?
Also what is the easiest way to reach the front bolts on the PS pump, from top or bottom? Thanks,
Thanks in Advance!

Thanks @shardul
I used a breaker bar to get the ACC belt off from the top and found if you remove reservoir first you can get to 2 front bolts on the PS pump. still a huge PITA.
Now just have to see how fun it will be to put it back on when I get it in the mail tomorrow.

So got it done!
Pro-tip... Don't put the reservoir on the new PS pump until you have the pump back in the car. Also use either e-torx ratcheting box-end wrenches or if you can't find those. A 10mm 12 point ratcheting box end will do the trick.
