You have some good advice there....

I remember when I first adjusted mine. All but 2 were way too tight. The sound of the engine was much different after the adjustment. The engine was much smoother as well. I noticed no difference in power though and gained about 1.7 MPG afterwards running B20 (at that time).

I remember a couple of the nuts being a little tricky to tighten. Especailly towards the firewall. Having the proper wrenches finally made the difference.


Edit: I used the PS pump too with no ill effects. That was with new belts and proper tension.
