Chevy Truck Heater Hose Quick Disconnect Removal DIY

Disconnect Tool: goo.gl/8aBwvf (Affiliate link)
dorman connector: goo.gl/yWPFGF (Affiliate link)
OEM GM Connector: goo.gl/ipEJwi (Affiliate link)
Removing the heater hose connector is simple with the right tool. Installing the new disconnect does not require the tool.

[@meestameestaaaaaa]

IF YOU DONT HAVE TIME OR MONEY TO BUY THE TOOL: cut an old credit card in half hotdog style. put 1/4 in. cuts at a 1/4 in. apart all the way down the spine of the card. proceed to flex the card into a tube shape. the cuts allow the card to bend easier. then put the card behind the connector into the space between the male and female connection. cut the card to length to have a good circumfrence. push the card deeper into the connection and pull the hose at the same time.

[@huseman21]

why cant you ditch the connector and just hose clamp the hose on the heater core?

[@markpasieka]

Im an OEM type of guy but this quick connect heater hose shit is the worst engineering I have ever seen... Chevy trying to incorporate proprietary crap

[@huseman21]

@@markpasieka It was really easy to connect, just about impossible to disconnect.

[@ever4437]

You can remove the broken connectors and just put the rubber hose back on the aluminum outlet and use a screw clamp and not use that gm pos connector and it will not leak nor come off. Make sure you get the hose and clamp past the step on the aluminum tube. Done tons of them.

[@hectordeanda9133]

What do you use for the “T”? I’m guessing a brass barb T would work best but would it fit?

Buy the better dorman 800-409hp,its stainless steel and shouldn't break again. It more money obviously but will definitely be worth it. I also have an 8.1 vortec with 398,000 on it and it runs great,no knocks or smoke. Great motors!Thanks!

[@mex9199]

What if you just connect the hose without the plastic piece you just replaced. I have a friend that says you dont need to replace the plastic just break it off clamp your hose back down ??

[@JOEJOJOJOEY]

Awesome video...why would chevy use this brittle plastic piece instead of putting the heater hose directly on the heater core pipe like they have done for 50 years???...SMH

[@chuy86]

Awesome video...I had no clue how to remove that quick connector in my Escalade. Man it helped me a lot and save me a lots of money. Thanks so much for such of valuable information. (I don't have any experience in auto mechanic but this video saved me)

[@xaviergalindo567]

Does this Dorman connector work for both white and black connectors?

[@johnrice1943]

Yes.

[@frmnjem86]

Great tip. But if you have to do the other hose right beside it, use the 3/4" orange release tool. Green might work, but it's hard to get to, I used the orange and it worked well. Just had to really get up in there to get it to release.

If your hose breaks off at the connector then just run a small flat head inside it and lift up to break it off

[@MollyBrown8]

Here’s how I did it: I tried those aftermarket off the shelf disconnect tool sets but I couldn’t get it to go inside the connector. I surmised that the part that needs to go between the pipe and the connector was too thick. The correct tool for this is a J 43181. Dorman makes this tool as 800-450. I ordered it from AutoZone and got it the next day. I tried it and it worked, but here are some tips. 1. Don’t insert it all the way. If you do it won’t work. You will need to insert it about half way. 2. After you remove the broken connector and before you install the new one rub some antifreeze/coolant inside it or you won’t be able to get it to go on the pipe. 3. As to why there is even a connector between the hose and the pipe, I can only guess that maybe due to vibration the connector is a kind of a sacrificial part so that it breaks instead of the heater pipe itself, but this is only a guess.

[@petecoots]

Amazing video, thanks for the part numbers!! Just saved me a ton of time, frozen fingers and a huge headache. My connector broke when it was 15 degrees outside. Picked up the parts and had it swapped out in less than 10 minutes.

[@huoshewu]

What is the part number of the actual hose? Having a hard time finding that. Thanks.

[@erospawn]

I got all ya'll beat.. My heater hose connector broke after travelling 40 miles to the middle of nowhere... And it broke off, just when I parked my truck in the parking lot..at an rc flying field. We used an old RC engine muffler, cut the pipe off... and turned it into a bypass connector.. Just bypassed the heater altogether.. It was around 95 degrees then...So now it's getting cold and I guess I better get to fixin it if I want heat this winter.

[@unliknoone]

OMG the fustration 😡 until i saw this video! THANK YOU THANK YOU! 😁👍🌹✨

[@micjam1986]

After watching this video I had an idea. I cut a 1" strip from a yogurt container wrapped it around the pipe a few times and slid it in to release the broken fitting. It worked. This video was so helpful..ty edit: it was a total of 11" of yogurt container strip

[@markd.williams5488]

No one said ANYTHING about a tool needed for this job. NAPA should have known this.

[@silentbravo]

Beware the Dorman part, I went to install one and the locking tabs slid right off the body of the connector. The whole connector is 2 parts, the little locking tabs are a small piece that slide into the larger part of the body. Looks like they forgot to put some glue in one of my 2 connectors and the locking part slid right off after I connected it to the heater core... The GM part's were around $30 each, vs the $10 for Dorman part. If your cheap Dorman part fails, there goes at least $40 in dexcool, not to mention breakdown time and any other issues that may be caused by losing all your coolant while on the road.

Anyone having issues pushing the new connectors on instead of using lubricants just pour a little antifreeze through the connector once the hose is attached the antifreeze is already a lubricant it will slide right on the heater core

I had to do just that to 2004 Silverado. But, what I don't see, is how to do a quick repair of a heater hose connector that breaks on you while you while you are on the road. It happened to me on a Sunday afternoon several months ago. What I did, was disconnect the hose going to the core ( wall panel ), and disconnected the return hose to the block. I made a "U" and reconnected the heater hose into the return engine block connector. I had bottled water in my truck, so I was able to replace most of the water and coolant mix and was able to get me and my wife home. Did my repairs the next day.

[@leighpotter8735]

You sir saved me from further frustration. I bought the same set that you used. I thought the orange tool was the proper one. I had purchased the aluminum 3/4" hinged tool from Amazane and gave up on it after 40 minutes. When you selected the green 5/8" tool I paused the video, went back into the engine bay, and three minutes later I had the dang thing off. I'm still trying to get the connector on the left off but that will wait until tomorrow. These two hose connectors have taken more time to removed than all the other hoses, the water pump, and idler pulley and tensioners COMBINED. I am seriously considering putting the hoses directly on the heater core nipples and clamping them down like every other water hose since Henry Ford. In short, thank you. EDIT: Today I went back to get the left connector off. I tried and was having difficulty. I decided that the tool needed a bit of lubrication. I used plumbers grease to lightly lube the inside and outside of the tool. Viola, the connector is off and I am putting my Silverado back together. I'm 76 years old so it takes me much longer to get things done. Thanks again Zent Rose for leading m to a successful end to my problem.

[@pedroleos2287]

Than again please advise how to put the new connector in just push it in twist it or what? I'm confused. Thanks anyway.:(

[@ZentRose]

yes just push it on there. If it is being stubborn, you can lubricate the o-ring in the connector with some coolant and it will slide right on!
