^ From the pic above it is OBVIOUS that he needs a '92 waterpump and a corresponding harmonic balancer! Thats the real problem.....

 

I'm going to take a pic of the WP pulley. I'll be right back.

 

TAKE IT FROM THE SAME EXACT ANGLE AS HE DID....!!!!!

 

Here....;

 

see the difference?

 

^ Dude, your looking at the BACK OF THE SERPENTINE BELT flipped inside out lol, that's why the water pump pulley looks like it has grooves in his pic, it doesn't though. Look at the picture that I provided, and SEE the routing of the belt. Your looking at the grooves in the belt THINKING that his water pump pulley has grooves, it doesn't....

 

^ The water pump pulley has no grooves, so the belt wraps around it inside out....

 

WHAT?? The pulley I just posted is stepped and his os not.

How cares about belt routing?

 

The above pulley in this pic has no grooves, your looking at the belt flipped inside out....

 

Again if that is his WP pulley it not stepped like the one I post, that is from a 88-92 Serp setup.

I'm done here untill he post some wider shots of his engine compartment.

 

^ Your wrong, done yes, but still wrong....

 

You see what you started....

 

His is clearly not stepped and mine is. How am I wrong?

 

Stepped not grooved.
----------
I didn't state that

 

His is stepped, your also looking at rubber grooves from the inner side of the serpentine belt itself. It wraps around the waterpump pulley inside out, why is that so hard to understand? As for being wrong, YOU said that you seen the A/C pulley, and it's clearly not there. Also, you got the following quote wrong as well when you wrote....;

^ I was not talking to you, I was talking to Aperion. Take another looksie and see....

 

Or just the correct WP pulley. Without better pics its hard to tell. I had a HB just like that with a 88-92 serp setup and it was lined up correctly.
----------
Not the grooves or no grooves for the belt. the over all profile of the WP pulley

 

^ no no, I know what your saying, but remember, in his pic, the serpentine belt is literally hanging off of the back side of the waterpump pulley, giving the impression that it's longer than it really is. Also, look at the area shaded to the left of the pic (the part that covers the sway bar), that is part of the pulley (the center section)....

Wait until he posts a better picture of the engine in full, right now everyone is shooting they're arrows in the dark. It's all speculation at this point until he clarifies everything....

 

It looks to far of center to be part of the WP pulley.

We do need to get better pics, that's for sure.

 

And here I thought the face of the balancer was the same distance from the face of the engine across all SBCs.

 

I thought the same thing. Just like the truck engine I had with the same HB he has with a 88-92 serp setup that lined up.

 

And the L31 5700 Vortec has a totally different HB than the ones pictured and a 88-92 serp works on that also. Of course with the correct pulleys and accessories.

 

So you feel it's the crank pulley then, too short....?

 

This is what we know from what little the original poster provided....;

* All his pulleys line up except the crank pulley, belt fits fine, just not centered....
* Parts guy brought out a harmonic balancer to the car himself and said that it didn't match, OP mistakingly referred to it as the crank pulley. Question here of course is what exactly didn't match in respect to the harmonic balancer....

... and that's it.

OP needs to measure the length of his crank pulley, as it should be 3.25" tall. If it comes up 1/4" to 1/2" too short, he has a different crank pulley from another application entirely. If it does measure 3.25" tall, then it has to be the balancer, what else could it possibly be...?

Yes, it's possible he might be running a truck serpentine setup, however, if every balancer face measures the same distance as the engine's face on SBC's, then it still wouldn't matter, everthing would still line up. What matters here is the length of the crank pulley from either a car setup, and/or a truck setup, to see if one is shorter than the other. And if it does turn out to be a difference in length, he's either running a truck serpentine setup with a car crank pulley, or a car serpentine setup with a truck crank pulley.

However, if it turns out that the two crank pulleys (truck & car) share the same length, then it has to be the balancer. Can everybody agree with this now, as I hold my eyes wide open while I write this....?

 

^ Meh, you guys are such wimps, couldn't hold out ehh, fell asleep lol....?

 

From the block (not the timing chain cover, from the block, ie the mounting flanges on eitehr side) the water pump pulley should measure 6 inches out.

We can then deduce that if the water pump pulley is 6 inches out then the serpentine setup will work. If the crank pulley is 3.25 inches out, then the pulley is correct. So the only thing left is the balancer.

One of those 3 wont match, figure out which one it is.

 

well my crank pulley is a lil under 3in, its not like the pic you posted which is a lil above 3in. and my compressor is on the passenger side

 

and that is the water pump at the top of the picture and i did take the pic next to the power steering pump. the belt isnt really hangin off the water pump.... its just on the back side of it like all the other pulleys but the crank pulley.... on the crank pulley the belt is on the front of it. front being away from the motor, back being closer to the motor.... and since my crank pulley is wrong, it took off two lines of teeth so far off the belt. thats why it is on the back half of all other pulleys other than the crank where its on the front half of the pulley
----------
o, and i didnt confuse the crank pulley with the harmonic balancer, the auto tech guy did. the auto tech guy came out to look at the crank pulley and said that the harmonic balancer should be in its place.... thats why i thought i might have a diff engine.

 

I just measured the truck engine with the thick HB (like his) and a stock 91 L98 with the thinner HB. No matter where I measure it from, the face of the HB is EXACTLY the same measurement from the front of the engine on both engines.

That would make the HB, NOT the cause of his problem.

It would make it a pulley or serpentine problem.

 

Better pictures of your whole engine compartment.

Does your WP pulley look exactly like the pic I posted?

Does your serpentine look exactly like the pictures that have been posted?
----------
You do have a different engine or HB and timing tab-cover than what came stock in your car.

 

Re-read the entire thread again, and understand that we're going on a very confusing situation on your part. Already stated on the first page, that if the crank pulley that's on the engine now is shorter than 3.25", then you have the wrong crank pulley on your car and need one for a 88-92 car application. Your pulley is under 3", which makes the question of 1/4" to 1/2" difference that you were initially complaining about answered....

I know, I'm the one that said that very thing (could easily tell that)....

When I said "hanging off", I was implying it not being centered, and/or plush with the pulley....

We know this, your pulley is at fault here, all else lines up....

You need a new crank pulley, and like I said in my initial post, the auto parts guy doesn't know his @ss from his elbow....

 

Dokken, your trying to solve a problem that isn't there. If you re-inspect my posts again. I only mentioned Harmonic Balancer because the auto rep stated that he, apparently, matched it up with the one in his hands, and the one on the car wasn't the right one. I always believed that the crank pulley was at fault here, not "just" the balancer. The only thing I disagreed with you with was the serpentine belt system in a whole, that can't be at fault if all of the other pulleys line up (which they do), it had to be the crank pulley, and/or balancer (which it was, his pulley is exactly 1/2" shorter).....

Here's one of my first posts before I even started arguing with you....;

 

Also, just wanted to point out Dokken, you just wrote....;

YOUR the one that implied the opposite with your very first post already knowing that his crank pulley was too close to the engine....;

^ You see? Your pointing to the balancer here, but your argument would only be plausible if his harmonic balancer wasn't all the way on, which would make the crank pulley too far away from the engine, not too close. Your now trying to justify your argument by making it out to be a question of distance from the face of the engine w/the face of the harmonic balancer. That is completely besides the point. I personally pointed to the balancer because the OP stated that the rep went outside and tried matching it with the correct one in his hands, then proclaiming that it was a completely different engine because of the significant difference. This is the only reason why I started pointing to the balancer myself....;

 

yea, pretty much the auto rep guy made all this confusion and had me thinkin wrong stuff.... but pretty much your right its just the wrong crank pulley on it since its a lil under 3in and spose to be 3 1/4in. sorry for all the confusion and thanks for the help .

But, now i have another prob with car.... dunno if i should post this elsewhere but ill ask anyways. my dad told me i should replace thermostat since the setup looked kinda old.... so... i went and got a oem replacement and now i installed it exactly the way it was just with new thermostat. i also cleaned the surface so it would seal back up right. so now my car is like overheating badly which it didnt do that before i even touched the thermostat. what could be the prob?

 

^ By taking off the thermostat housing (the water neck) and replacing the thermo, you allowed for air to enter into the system, creating air pockets in the cooling system. What you need to do is (with the car cold, DO NOT open the radiator cap with a hot engine), remove the radiator cap and turn the engine on. Allow the system to circulate for a few minutes, you can even allow it to circulate once it starts overflowing the radiator itself. After a few minutes, all the air should be out, and you can re-cap the radiator. That's all it is....

 

Keep topping up the radiator while you're running the car with the cap off too, otherwise you'll never get all the air out. Put the cap back on after it starts to push coolant out of the open neck, and make sure you've got coolant in the reservoir.

 

actually i didnt do that yet, so i need to do it.... but i found the prob... wires from electric fan wasnt connected all the way.... people i bought it from has electric fan hooked up to a/c so if a/c off no fan so i gotta keep a/c on to have fan on... funny thing is i have no a/c either it only blows from dash and not from vents, but ty for help all i really needed it and yall were there... thx alot . ima be replacing crank pulley next week when i get paid... car been draining my money so i gotta wait for it lol. where is a good place to get a new/used pulley from? i tried lookin up on some local auto part store websites and they only have pulley sets

 

Again Street Lethal, he asked if he might have and different engine in his car. I pointed out that the HB and timing tab was not correct for stock 3rd gen F-body car.

YOU kept saying the HB was the problem so you were wrong also.

98 TA is what you have shouldn't you be on 4th gen sites and not a 3rd gen site?

 

GM has them still I think or post in the Engine/Drivetrain parts wanted on this site, I'm sure someone has one. Make sure its from a 88-92 serp setup.

 

Dokken, in case you didn't realize yet, I'm only busting your ***** bro lol....

 

the fans come on automatically when you turn the a/c on from the factory, it isn't something someone else hooked up. The reason it over heats w/o the a/c on is likely just a bad fan switch.

 

also any autoparts store should be able to get you the correct pulley.

 

well the fan is wired straight to the a/c lol, the people i bought it from told me they rigged it that way
