Simple job went south. Any tips on how to get the crappy pot metal heater hose fitting out of intake manifold after it's already sheared off?

This is how I did it , stuff a piece of rag in the hole to keep junk out . Use a short section of hacksaw blade held in vicegrips to saw thru the pot metal piece in thirds . Use a pick or sharp nail to tap the piece free from the threaded hole . You should feel the difference in cutting when you rake the steel threads verses the pot metal . Easy does it . Good luck .

They make a simple remover tool for just that job i think around here it was like 9 bucks all you do is tap it into the hole then put your socket on there and out it comes.

There is no "simple" removal tool when you have to dig each thread out with a pic. I believe there is a link up in the "searching for info" regarding this fitting.

This happened to my dads. We took the manifold off to make it easier and chiseled them out then completely cleaned the manifold while it was out. Then we went with a regular heater hose and a standard typee of fitting,no more quick connect!.

OK Choaf, you're answer is intriguing. Have you personally done this and where would you get such a gem?

He's right, they sell a tool made specifically for taking out this fitting at O'reilly's for about $9. It has very deep straight flutes that you drive in with a hammer and then screw the fitting out with a socket. I bought one and it removed the fitting with ease. They also sell the new quick connect fitting to go back with, it looks to be made better than the factory one, and it cost around $10.

Good news. Too bad I was antsy last night and already have the manifold ready to remove. That tool was hard to locate but I did find one. Dorman 800-408 sold Here

Thanks for all the useful info.

The special tool is a pipe thread easy out. Some times they work well, other times they don't and just grind shavings into the hole. Worth a shot though as it can save a few hours. I see them in the red HELP items section at AutoZone and O'Riellys.

This turned out to be some sort of molecular bond. 15" wrench and 2 lb sledge would not budge it. I turned to the air chisel. This got me close but there's still a lot of clean up. I need either a large tap or a NEW manifold.

You need a 1/2" pipe tap, it's tapered so do just as much as you have to as it is possible to enlarge it too much. Turn it a little bit at a time then back out to clean the threads/tap. You can grease the tap and it will catch most of the filings.

Sounds time consuming but really isn't. If the threads are full of material near the outside of the boss, use an ice pic or awl to clean out those first.

yes I broke mine off and did the hacksaw blade trick. Worked great, and I used a shop vac to help retrieve chunks of pewter. It actually sucked up quite a bit of coolant with it, so I assumed it got all the metal. I picked big chunks out by hand (grabber-thingys, etc). But using your finger or something with grease on it will also grab a lot of metal crud out of the threads. I used a small awl and 90 degree pick to clean the threads too.

here is my ubiquitious cut and paste:

_________________________ ______

Yep, that pewter fitting is another GM piece of junk design that maybe saved them a few pennies in manufacturing/sourcing but makes life down the road for the user (us) a PITA.

The new GM steel fitting is 24503681

I bought mine from gmpartsdirect and the package came with two (one parts bag) Each were $6 but both came out to $12. So I gave my other one to a friend.

My old pewter fitting snapped off IMMEDIATELY when I put a wrench on it. I used a deep well 29mm socket (I think it was 29... anyways it was big), and I had soaked it a few times with PB Blaster, but it didn't matter.

Since it snapped off like so many do, I had to use a hacksaw blade by hand to cut 4 grooves into the broken pieces to get all the threaded parts out. It wasn't too bad really. I was careful to grab the chunks of pewter so they didn't fall into the intake manifold. I cleaned the threads by hand well (didn't run a tap through there since I couldn't find that big of a size - but that would be ideal). Used a shop-vac to suck pieces out, truthfully I sucked a lot of coolant out from the intake LOL!

The heater hose just snaps right out with the little plastic clips. The new steel GM fitting comes with female plastic clips so once you get the new fitting screwed in there tight (it comes with sealant on its threads but I still used a little black high-temp RTV because I did saw a tiny bit into the threads in one place), you just snap the hose back in and you're done! You will lose some coolant along the way so, have some on hand to fill it back up. I waited a day to let the RTV seal and dry completely. Then I ran it up to temp and played the coolant level game.

All in all it was not that bad of an ordeal. I was prepared with the hacksaw blades because I had read here that the pewter crap would break, although I did have to grind down the hacksaw blade because it was too wide to get in there and do the sawing.

that fitting doesn't leak a DROP now...

I remember

There may be difference in whether or not the piece goes into cast iron, or aluminum. There is certainly, a different chemical reaction between them.

I knew well, from what grief you guys were having I was going to have to pay my dues eventually and likely at the worst time like there is ever a good one.

When I first saw a total of maybe, 10 drops underneath it, I reached down to check the quick connect hose end--------gently, and the whole thing came off in my hand. But I had carried the steel replacement with me for 5 or so years, nearly 200K miles, it was time.

I have had to replace 3 of these p i a fittings so far and all of them broke off. I was being real carefull to use a box end wrench or socket but it didn't make any difference. Slight turn of the tool and snap! then crumble. I cut 4 slots in the fitting with a hacksaw blade and chipped out what I could with a narrow chisel. I couldn't find a 1/2" tap so I made one out of a 10" long piece of black pipe threaded on each end. I used my angle grinder to cut 4 slots longways through the pipe threads to resemble a tap and it worked like a charm. Cleaned the left over fitting pieces right out of there. And a lot cheaper than a tap too.

My son has a 95 with 70,000 miles & I am wondering what to do with the heater hoses. They are original & after reading the above, wonder about replacing them. He's coming tonight to change antifreeze & radiator hoses. No stores open tomorrow if we run into trouble. Any sugestions?

Mr. Reid,
I'd recommend if your worried about the fitting on the intake and no stores are open and you do not have the replacement fitting, the OEm or the pipe one, then don't mess with them at all. Sometimes they can be fine until you breathe on them and then they fall apart.
Get the parts first so you can fix it if need be when you do it.

deffinately get the part before you take the old one off.

who knows, you may get lucky and it might come right out.

i've done 2 of these fittings total on high mileage (150+) and they both came right out. it might help if the engines good and hot, who knows haha.

but on a 70K engine i would think your fitting would be a little stronger, not as many heating and cooling cycles.

Thanks for the replies. He decided not to bring it even though he has the fitting. Is only 1 of the fittings a bad one to replace? It seems that I looked at it one time & didn't see anything that looked easy.

Thanks for all the great ideas on this problem. I broke my son's last night and was at wit's end how to fix it without removing manifold. I did read another site that said someone had cracked their manifold while using an easy out so care is the big word! I'll get all he 'tools' together and give it a try tonight.

I was just wondering if it was sprayed with PB blaster ahead of time would it help to get it out. Also if the vehicle was hot and you put ice in the fitting just before trying to remove it. Anyone tried either of these?

You could try those methods, no harm in them, that's for sure...but they won't do much (if anything) for the main reason the thing breaks; the material is corroded and weak.

its easiet ive found is to remove the intake so you can clean the intake out and go ahead and check your rods and such and get a glimps of the condition your heads are in. But mainly so you can sit it on a bench in front of you and take the time to do it right without worry of droping crud in the engine. Plus not much room to move in the back of the engine bay.

I just fixed this problem on my 95' it was leaking pretty bad.

I got the truck this way....When I went to take it apart I discovered that someone bent the fitting and I couldnt get the aluminum tube out because the plastic clip had absolutely no chance of coming out...

I pulled and wiggled at the fitting...It broke off and wasnt that hard to get the tube out once the plastic was cut away with a razor knife.

I bought the Lisle tool that hammers down in the remains of the fitting....But it was too loose a fit and the fitting was too far gone so it just spun and made a mess.

I ended up sticking a 3/8-18 NPT tap into the hole and cranked it down in there....It was a size smaller but it cut out alot of junk.

Then I was able to take a pick and a hammer and chisel out away from the threads a piece of the fitting. Once I got behind it it was all over in minutes. I plucked it out with some needle nose and then I couldnt find a 1/2" NPT tap....

So I found a spare 1/2" fitting laying around the garage and cut 4 longitudinal grooves with my cuttoff wheel to act like a tap. I threaded it down into the hole to clean up the existing threads nicely and then I installed the "Dorman" steel replacement fitting. Worked like a charm.

No more leak and the truck could be driven again!
