Getting ready for the header install and just pulling stuff out so when the time actually comes it wont take as long. I started ripping the smog stuff off last night. I got that little black plastic box w/ all the tubes going to it right over the passenger side cylender head off and the pipe that holds it in place. Now if im looking at my engine correctly the actual pump is drivin by the serpentine belt and is located right under my AC pump. How do you get that out of there? or do you just pull the pulley off and re-route the belt accordenly?

One more thing, the tubes comming off of the manifolds, will these come off with the manifolds or do i need to pull them off before i do the manifolds?

 

You are correct

No. You have two options here. You can leave the pump on and just leave it there until it siezes and makes funny noises or you have to remove it. There are two torx bolts that hold it in. You need to take those out and the pump will come off of the bracket. i find it easier to take the whole bracket off and remove it outside of the car. You will fight those torx bits to the death because the aluminum of the brackets swells over the bolts that hold it in. Don't worry, just sewar a lot and be patient and they will give. You cannot just remove the pulley and re-route the belt becaue the pump sticks out to far and will rub on it. You need a 96.8" belt. Check the tech article for the dayco part number.

They will come off with the air tubes on them. Just dissconnect the main hose from the top of it and leave the air tubes on them. Mine were completely frozen in place and would not budge. Not worth the effort to remove them if they are not going to be re-used.

 

can't you just gut the smog pump and have a free spinning pulley?

 

sure but it looks kinda dumb,just take it off and reroute the belt

 

it would be easier to just pull it. The pump is an enclosed unit that you wou;ld have to hack apart to gut it. Even after that I would not trust its strength over time and I could collaps because of the thin casing not being supported by the guts. Once you get it out you will see what I mean. It is like gutting your altinater, just can't be done really without destroying the whole thing.

 

A third option would be a delete pulley. Part # 10186167. I have it. It's great. Gives a nice clean, stockish look while eliminating all the garbage in the way too. Plus you get to keep all 4 bolts holding the accessory bracket on, instead of just 2 without it.

 

I don't have a serpentine belt so it will be really easy to get rid of

 

*** I hate that torx bit, I stripped it and I had to stand on the accessory bracket while Shifty put a set of vice grips on the bolt and turned it (and me) until it unfroze. Becareful you dont strip it. While you're at it you minus well kill the heater valve thingy with the 50 hoses going into and out of it.

 

torx bits are so damn useless.

 

Well i dont really know what a torx bit is but i have a feeling i'll find out in about 15 min when i go back out to work on it. That heater valve thing you were talking about, is it the small circular valve above the passenger side valve cover towards the front w/ about 3 hoses comming out of it? what does it do? second the AC, what do i do about it? can i disconnect those hoses what will i need to pull out and put back in? thanks again.

mhhh. I will also install some headers on mine. I also have an pulley deleter for the a/c. can I remove this also? what kind of belt do I need then?
greetings

Well if you have the AC delete pulley you do not need another belt. You only need another belt if you remove pulleys like would upon removal of the smog pump. Delete pulleys are in the same location and same size as the one that they are replacing. They are just free wheeling and do not create any drag by turing an acessory.

 

Go to the main page of this website - www.thirdgen.org and look in the section entitled "tech articles"

amazing what you'll find!

 

Chuck, I wish I lived closer because I would just love to watch you work. I could use a laugh, and I could teach you some good "hack tricks". Not that I'm a hack, well not most of the time any way. But some times the unconventional comes in real handy.

Later, Dave

 

belts should be replaced every 25k miles or so... I know for a fact mine was stock, since it was so entirely chewed apart.

 

i dont see why you guys had a hard time getting it out of there. the torx bolts came out pretty easy. i left the AC pump bolted in and i was able to get it out of there.

 

Stupid torx... what size are they supposed to be anyway, I have t-40 but I think that might be too small. Taking the whole bracket would mean dealing with the a/c right? I'll go look. I just don't know why those bolts weren't the standard f-body 10mm or 13 mm.

 

mine was a T-45 bit. didnt strip or anything yanked with my ratched and it broke lose and i took them out and slip the air pump out. was a tight squez but it fits without removing the AC compressor.

 

The bottom one on mine came right out and the top one fought tooth and nail. I unbolted the AC and layed it asdie and was able to get some vice grips on it and turn it. The next time I did this to someones car I took off the whole bracket. It is only 3 bolts after you have the AC layed aside. When it was out of the car it was 85973489573 times easier to get it out.

 

That's the water pump pulley.

The smog pump delete pulley is GM part # 10129569

 

.

 

The part # 10186167 shows up at GMPartsDirect.com as a water pump pulley. I guess they have their description wrong??

My friend has an '88 S-15 with the serp. belt, and his stock one looks more like the one I listed but flipped over so the pulley is closer to the a/c compressor pulley. Keep in mind that his truck never had a smog pump from the factory, but still has the space for one.

I guess I'll have to take a picture of his to show ya'll.

 

yes, their description is wrong. I have it.

 

.

 

Yeap. I got one one mainly because of you. Thanks for shedding the light on this little known piece and it's advantages that I had never really thought of before.

 

Also, I think Part #10129569 mentioned is a smong delete pulley too, but I don't like the design. It has short bolts that do not go into the block like the factory setup and it generally just doesn't look all that great to me, which is why I got the delete pulley in the first place. With 10186167 you keep the stock belt routing which means you can use the stock belt which pretty much offsets the cost of the pulley itself so the cost factor doesn't even matter, you eliminate any belt flopping some people have, and you keep all the bolts holding the bracket onto the block. It's a win/win situation for me.

 

Where would you route the belt if you removed both the Smog pump and A/C?
From lookin at the Tech Articles, it would be impossible and you would need to get an A/C delete idler pulley. I planned on doin it this weekend, glad i found this before i started rippen stuff apart...

 

Click here and there's a guy that had modified had moved his alt to the other side.

I wanta keep the a/c but try and clean the s*&% up a little on the pass side. By taking the smog pump out would through a code in the computer?

 

No it will not throw a code.

 

what is the heater valve thingy?????? im gonna remove my AIR but keep my A/C can i loose this heater valve thingy too?

 

Yes, you can get rid of it. The heater valve is the large black box directly behind the AC pulley on the passenger side. There's about 4 large hoses and 4 wires going to and from it.

 

The heater valve has three hoses with coolant and one vacuum line attached to it.

 

Oh, shoot!! My bad. I thought he asked about the smog pump diverter valve. Guess I should have thought about it for a second before posting.

 

alright guys.................now im confused. i removed everything that has to do with my AIR system except for the air tubes from the exhaust manifolds i cant get off. so that means (i guess) i took off the smog pump diverter valve (if it was the black box with two plugs in it) but what is the heater valve?? is it different and can i loose it?

pictures would be nice but a description would be great also!!!!!

Heater Valve

 

ok now that i know what the heater valve is can i get rid of it...its pretty ugly. ive heard of a Throttle Body Bypass mod but what exactly is that. i still want cold AC and hot heat but not the heater valve. is this possible????

 

I would like the answer to that one too!!! :hail:

 

.

 

i got a quick question for u guys... is there a "HOW TO" for this operation of smog deleting but keeping the AC/HEAT working.. i coulda swore i saw one written by someone then i freakin lost the link... .please help me out im plannin on doing this project this weekend... also if u can let me no (if there ISNT a "how to" on this), what parts i will need and sum basic directions.... i no i will need part # 10129567 which is the pulley of course ... will i need hoses? new belt? thanx

 

is this what you want?

 

Check out the new to TBI thread at the top. There are links to the smog pump delete in there. You can also find the same article in the technical articles page on the main page.

 

(Pablo) wow thanx for being a big tuff guy and answering me with sarcasm... it was a simple question.... i thought a forum was to relay information to others about a topic... not be a d1ck... thanx for being immature and also thanx for the help...

(ShiftyCapone) thank u for not being a punk like Pablo

 

YES you can. i have gotten rid of it, and yes, my heat still works, just fine.

you just bypass the valve, so that the coolent flows to and from the heater core correctly.

 

Dewey,

Man, I wish i'd have known that before I went out and bought a new heater valve.

So which way did you run the hoses to make it work right? Maybe lemme see a pic of it?
And what did you do with the vacumm line?

 

i know, i really needs pics of it. i'll try to get some this week, and i will make a post that the, ever so kewl, mods of this board, might just make a sticky out of

 

I havnt seen my car for a few weeks but I think this is how it went:

manifold to left (looking at heater core from front of car) nipple, right nipple to hard line which will run to the radiator. Find a t-fitting for the vacuum line and tap into something else, it will work fine.

 

do u need to take off ac to remove smog then re install ac then complete?

 

Nope you can leave it intact. If you have problems getting the top bolt out of the smog pump you can unbolt and set aside the AC compressor so that you can get some vice grips on the bolt.
