Re: Tightening Power Steering Belt?

Some GM models had a 1/2" square slot for a breaker bar to pull the pump tight, but we got left behind.
I think it's part of a conspiracy to make us damage our pumps and have to buy new ones.
I would suggest giving the belt a good spray of belt dressing and see if that helps.
Or, find a way to pry on the pump housing and not damage it.

Re: Tightening Power Steering Belt?

If you have a/c you need to loosen that first, then tighten the power steering, then tighten the a/c again.

Re: Tightening Power Steering Belt?

I just use a pry bar between the water pump and power steering pump.

Re: Tightening Power Steering Belt?

Oh yeah, how to pry. I use a wrench on the welded nut of the bracket. The one the bolt from the rear threads into.

Re: Tightening Power Steering Belt?

You could use a v-belt tensioner.

Re: Tightening Power Steering Belt?

I use the 90 degree end of my "Wonder Bar" pry bar against the frame and tuck it under the driver's side of the power steering bracket to lift it up into position.

I tried a pry bar between the water pump and the power steering pump, but the power steering pump metal feels so weak I just didn't feel comfortable prying against it.

Re: Tightening Power Steering Belt?

make sure you have this in place too,it can be tricky to keep tight if this bracket is missing

Re: Tightening Power Steering Belt?

Please forget that I mentioned using that V-belt tensioner it will not fit in between the pulleys.

The gap between the crankshaft pulley and the power steering pump pulley is only about 1-1/2 to 2-1/2 inches apart.

The last time I replaced the belt I think I used a 2x4 to pry between the frame rail and the lower edge of the power steering pump bracket.

Re: Tightening Power Steering Belt?

There was a tool I bought years ago when I worked at a GM dealer, it hooked under the the bracket and had a 3/8" square hole for a breaker bar. Just pulled up on the bar and tighten the adjustment bolt. If I can get a picture of it, I'll try to post.

Re: Tightening Power Steering Belt?

I remember that tool way back when and I was still wrenching for a living.
Almost bought one.

Re: Tightening Power Steering Belt?

Don't mean to bump though perhaps this is of value, at least on the 71-72 BBC pumps there are two thread holes, I believe these are exactly for tensioning the belt, eazy peazy & no damage.

IMO do not pry on the pump housing at all, I've done it before but this time I cared

Seen what happens to the top if you let your alternator go Ha!....It's why I bought a truck for my truck I guess donor was still good. Speak of alternators, I installed a 10SI with factory valve covers, wholly smokes tightened that can't be more than 1/4" off the valve cover. Surprised to see that, my 72 has an old alt, chrome covers and different upper bracket, the alt is off the valve cover by a mile on the same belt.
