Belt diagram

does anyone have a belt diagram for a 1990 P30 chassis? I have four belts on there, and am having issues remembering where one was routed. I have the 454 carbed with air pumps:S
  • If anyone would like to know,I found the best way to tighten up the power steering belts is to use a long 1/2" torque wrench (18") with a 3" extension placed in the square hole on the bracket. Really no other way that I could see. While pulling with the big torque wrench, I used a 3/8" ratchet with a deep 3/4" socket to tighten down the bolt to secure the pump. Not very fun, would be easier with the radiator out but, that would take some time removing.
  • Oh boy, am I blind. Theres a belt diagram under the hood on the firewall

    yep, did it, the belts are on but tightening up the power steering belts is proving to be a challenge for me. Loosening was simple as I pushed down on the belts once the bolts were loosened.I can't see a place to get a pry bar in to pry.This really would be easier if one person was underneath at the same time. Wheres my grandson's when I need them? Oh, thats right, there playing video games.haha, Well almost there. Thank you, sir
