power steering belt - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Got a new power steering belt. Got the one for no ac since I removed mine. But it is way to short? What is the diference in belt routing? Mine goes around power steering pully crank and fan pulley. This belt looks like it would not fit around only two pulleys?

Thanks

i have a 4.3 motor which im told ( dont know for sure) is the same routing as a v8. i have no air conditioning and the powersteering belt goes from the waterpump ( or fan) and around the power steering. you adjust it by moving the power steering pump

76bonanza · 12-11-2003, 09:43 PM

Not around the crank? Looks like the belt would work that way any on whitch way would be better?

76bonanza · 12-12-2003, 09:04 AM

Can anyone else tell me how there P/S pump belt is routed?

Nvbowtie · 12-12-2003, 09:53 AM

mine is same route as yours, I thik my belt was 43" (# 1543)

(get out the wifes measuring tape from her sewing kit and measure to be sure)

you may be able to see in pic below

76bonanza · 12-12-2003, 10:01 AM

Nvbowtie yours is same as mine? Over water pump and crank?
Thanks

76bonanza · 12-12-2003, 10:07 AM

Yep same as your route,
the belt is called a TopCog by Dayo or Dayco ??
(any parts house stks them)

Are you SURE all the brackets are the ones that were on the motor? There are two Power steering set ups for A/C. The actual PS bracket can be bolted to the wrong one and then not enough swing to get it tight.

I can look at my 75 tomorrow and see if I can read the belt part number. I know it has the correct brackets.

**swervin ervin** · 12-12-2003, 01:22 PM

Are you still running the double pulley on the PS pump? I removed my AC also and bought a single pulley from the dealer. This is the pulley used when the truck didn't come with AC. This is what I was told anyway. It is smaller in diameter than the dual pulley. Anyway, the belt is routed just like yours, over waterpump, crank, and PS pump. I'm not sure on how it is supposed to be stock though.

The part number for the belt I use is a Dayco Topcog, 15450.

76bonanza · 12-12-2003, 01:47 PM

I have double pulley on P/S double on water pump and triple on crank. I think the brackets are same has little ear on P/S bracket for A.C.. I think he gave me the belt for none A.C.. But even still the only place it would fit was from crank to P/S or water pump to P/S. One othe question were did the A.C route then? Just to P.S. pulley and that is it?

76bonanza · 12-12-2003, 01:50 PM

Also I would think it would be better routed in the triangle fashion than just right to the crank or water pump dont you guys?

allthrtl · 12-12-2003, 01:58 PM

Just use a piece of string and mark the length. It's best to measure from the bottom of the groove, think of it like the inside diameter, take the string to the parts store and let them put it on their belt mearsure device....Bingo, right size belt...

**swervin ervin** · 12-12-2003, 02:00 PM

I was talking about a double pulley on the PS pump. My truck had the double PS pump pulley stock, with AC. It had one belt going from the crank around the PS pump only. Then it had one going around the water pump, crank, PS pump, and AC. When I removed the AC, I tried to run two belts on the PS pump. I kept the crank and PS pump one and added one to the WP, crank, and PS pump.

I bought a AGR PS pump and my old double PS pump pulley started slipping on the shaft. It was working it's way off and throwing belts. I went the to dealer and bought a single groove pulley. Again, since I've never owned a truck that didn't come with AC, I have no idea how it was routed stock, but I prefer to run mine like it is now. This gives me one more belt going around the crank and water pump.

76bonanza · 12-12-2003, 02:09 PM

I guess that is my thought I can do either just from crank to p.s. or from crank to water pump to p/s. I would think like you that it would be better around both the crank and water pump. One more thing with it set up like yours do you have to raise the pump to tighten the belt? Mine is a little off from striaght up and down that will not hurt it will it? Maybe an inch or two from center toward the crank? I was also thinking of running two belts do you think that is what messed up your other pulley?

**swervin ervin** · 12-12-2003, 02:25 PM

So you do have a double PS pulley. If it were me, I would replace the double groove for a single. No, I don't think two belts is what messed it up. I think just pulling it off and putting in on so many times was the cause.

My pump leans toward the water pump also. They all do. You don' have enough slack in the adjustment to have it sitting straight up.

76bonanza · 12-12-2003, 03:42 PM

The only reason I am concearned is it has been squaling alot since the cold has set in. It is a new pump. So I think the belt is slipping and I was wondering if running it just crank p/s pump would give the pump more pull? But you do think the three way belt is better than just from crank to pump?

76bonanza · 12-12-2003, 04:23 PM

One more thing I have not yet been able to find those topcog belts any where?

**swervin ervin** · 12-12-2003, 04:31 PM

I don't know if they are any better, but I just like the fact it's around the water pump too. It makes me feel better knowing if the alternator belt breaks, the water pump will still turn. I've had alternator belts break before and if you don't have another belt going around the pump, you can't drive it.

I bought my Dayco TopCog belts at Advance Auto Parts.

**swervin ervin** · 12-12-2003, 04:34 PM

Oh, and don't get sticker shock. They are 2 to 3 times as high as a cheap belt. The 15450 was $11.70.
