Lol. You’re gonna love when that leaks or takes out your heater core. It’s a restriction for a reason. And it’s a quick connect so it takes 3 seconds to disconnect it while pulling the intake off.

Well done, one of your best. I don't know what GM was thinking, mixing aluminum and steel fittings in the presence of continuous water. Of course it was a long term disaster, done to make the task for assembly robots very slightly easier.

Nice update. Manufacturers have been trying to do away with clamps and rubber hoses because it takes time to fit them correctly the factory. Also hoses need to be routed correctly so they do not rub or leak. I remember in the old days having to fix up problems with hoses on new cars.

Sometimes the restriction is to lower the volume/ pressure before components as not to over pressurize it

The best reason to use a restriction in the heater hose is to protect the heater core. On engines that can rev quickly, they can generate pressure surges that can over stress the heater core.

@@leewon4572 I've never had any trouble with it. Don't have to worry about it leaking either. My fitting was leaking and snapped off in my intake way back then. I was trying to get the broke piece out and damaged the intake unfortunately, so I replaced intake and put in the barb fitting. I wish I had known and could have changed it prior to that to the issue. That's why I try to warn others. I still drive my 98 everyday, even though I got a newer truck. Thanks for your service as well 👍

Love the fact that you are all about that Suburban. Had been couple years now and always loved your content.

the purpose for the quick connect from the factory was: 1. faster vehicle assembly at the factory 2. more profit for manufacture due to time saved. 3. cheaper vehicle for the customer due to time saved. that quick disconnect made sense at the time and only needed to last as long as the vehicle warranty.

I had a 1992 gmc truck that had the same factory fitting go bad.... I agree the quick disconnect is flimsy, I have a 1994 gmc now , that I want to do this conversion to. This video is a great self help tip. I would hate to be stuck on the highway in a storm , trying to fix the old set up, lol. 😂

It is a water restrictor limiting the amount of water for cooling. Barbed fitting works great also. Not that your is a diesel but Leroy Diesel sells an aftermarket brass connector with the restrictor that he makes.

This video came out at the PERFECT time! I was putting seadoo in my suburban and noticed a leak coming from this exact location!! Well i know for sure what im doing now!

I did the exact same thing on my 1998 GMC Suburban a few years ago. mine was in the front next to the thermostat housing. It was also much less expensive to do it like you did, rather than replace the crappy quick connect.

The brass nipple is likely 7/8" Not 23mm. I noticed that heater hose QD when you did the intake gasket video. It does seem to cute by half. When you replace those nipples, always use brass, not steel. Brass is more noble than iron/steel, it won't corrode in that application. Steel will always end up corroded no matter how nice the zinc plating looks. The zinc is scraped right of the threads on 1st install. If all you can find is steel, install it with copper anti-seize. Also, do not over torque them, they are tapered pipe threads. That's a big reason why you shouldn't be using 1/2" drive ratchet/sockets up there, they will help you over torque. Save the 1/2" drive stuff for chassis work. 3/8"drive up there is all you need, and it is easier to work with in confined spaces.

I've been there. The threads on those intake manifolds will be half worn out/corroded. You need to clean them up AND use silicone sealant. Torquing a brass fitting in alone will likely not seal it. I put steel Dorman 56237 fittings on my last two with silicone sealant and they worked great.

I had the same exact situation with a 1998 Chevy 3.1 Malibu. They had a lot of plastic fittings that one day your driving and you then find your engine overheating because that fitting snapped off. Got rid of the quick disconnect with a brass fitting and hose.🎉

That is an extremely common problem with the tbi motors. The fitting is made from a low alloy and crumbles like you said. I'm actually surprised that you chose to eliminate that joint.. since I feel you are very hesitant to change anything from the factory. It should give you years of service life like that now.

Hi jimmy First of all ptf tape comes in 2 types, there is liquid and there is gas ptf tape. Plummers tape is the liquid ptf tape veriant. Gas engineer tape is the gas ptf tape. Liquid ptf tape for water, coolent and suchlike that do not use tapered fittings. Gas ptf tape for all gas applications that do not use tapered fittings. Something else brass and aluminium do not form electrolysis, corrode, they are none ferrous metals so are good with each other. Any metal with iron in it as a base element will cause electrolysis as iron reacts with water. The quick connection are for easy disconnection and reconnection in manufacturing and for the dealerships to charge more for labour as if they have to fit pipes the old way with barb connectors and clamps, plus to have the owner change the hoses more frequently than needed. Good work on the replacement and it is far better flow of the coolent with no restrictions.

I did something like that on a 1968 Oldsmobile back in the middle 70’s. It had a plastic heater control valve from the factory. The plastic valve had a restriction in it. My replacement fitting didn’t. Every time I accelerated around the corner from a stop I could hear water rushing through the heater core because water was rushing through the core too fast. I did it as a temporary fix but drove the car 6 years like that. Plastic heater valve, $ 18.00. Brass fitting $ 2.00.

these stock hoses are highly known to suddenly break off ontop of the motor leaving only the threads. rough stuff. super great upgrade

That’s the first thing I do to my 5.7 vortec motors in my trucks 👍except I use a threaded nipple and a street 90 then hose clamp the heater hose to the 90. Never have to mess with it again until the heater hose busts because you installed headers and it was too close to them 😅

Excelente Maestro!!! 😊

Alum. and brass = electrolysis? I suspect the orifice size is to reduce flow from the engine back to radiator via heater core, thereby decreasing the engine warm up time which enhances ring life and block dimension stabilization.

My only question did the heater blow hotter? any noticeable difference with the larger inside diameter.

Did all this years ago on my ‘88 350 Chevy. Dug out the broken threads with a pick. Was a pain.

Mine goes right back to the heater core wall is that cool? Gonna attempt this today

Can you let me know what size hose you went back with I appreciate your time the black rubber hose attached to the new brass fitting

Hi Jimmy great video, it's been 7 months have you had any problems with the new part.

You can actually get the part for a 96+ blazer, which has the proper flow restriction to replace that instead of pipe fittings. Did it to my truck about 10 years ago, still holding up. Not sure if you can buy them new anymore, but I'm sure there are loads of them in dead blazers at the junk yards.

You can tell it's a real problem when Lisle makes a tool that can sometimes get the NPT fitting out of the manifold. I changed my grandmother's manifold fitting years ago. I got the Lisle tool and it didn't work and had to pull the intake.

I felt that pain and anguish through my phone

There is a reason why most plumbing fittings are brass. It is self lubricating semi soft metal that wants to move apart. I removed a 40 year old dishwasher that was installed with brass pipe and fittings. It all came apart like new pipe.

The quick release are for you to use on track day😜

Hi, Rudy, Listen to Dale. The proper ( not cheap chinneesium) constant load clamps are far superior and reliable. Even if you fold over the tail end of the screw clamp, you sort of prevent one issue. The temp changes in an engine, plus, the even pressure all around, plus, no damage to the outer skin of the hose... Never on a critical system.

Yes you always have to keep tightening the screw clamps every year. Constant pressure clamp is the way to go.

My 96 has 440,000 miles, i live in cleveland with winter and salt. I have never had a problem with this piece. I replaced both the hose and fitting at over 250,000 miles just as maintenance from the hose rubber getting weak. Yours was so corroded, i would look at not flushing the coolant when the anti corrosion properties weaken. Most people dont even look at antifreeze condition, unless themselves are a mechanic.

Quick release was for faster factory installation purpose only...not the first company to do so...

I replaced the fitting and the clips on my 97, and it weeps coolant in the frigid Canadian winter weather. Thanks for illustrating the fix!

wish someone would make a AN solution for it

lol anyone who has any vehical with this engine has had that heater hose quick disconnect break. It will break on all of them eventually. If anyone has one that isnt broken best to take it off now and replace it with something different.

it's not so much a matter of it being poor quality metal; just that its dissimilar metal. brass a much better choice. aluminum would be ideal ofc i like the pex fitting. looks like it should "grab" a little nicer than a standard barb

brass and aluminum will make corrosion there
