5.3, 4.8, 6.0 Silverado Sierra Common Coolant Leak Area. Heater Hose Connectons Get Replaced.

[@jeradmartinez4266]

Never learned anything more in my life than this video thank you online dad

[@SChacon1988]

This video is exactly what I needed to fix mine. I had no clue how to start and remove the hoses in the firewall side. Thank you

[@nathanolson2134]

Dude this video saved me so much money and time. Saw this on break at work and went to the parts store after I got off and took care of this in about 30 minutes. Much thanks!!!

[@shemp308]

I was a mechanic and this is absolutely the best explanation and show of how these fittings I have seen. Good job!

[@mikeberry9584]

KENNY, I always learn something out of each video you share with us the water pipe fittings on the core that’s new to me. Keep wrenching.

[@ElleBrOw]

New here 🙋🏽‍♀️ Yes I learned a lot out from video. Basically learned what to show or tell my mechanicS. Yes coupla of them first said I had no leaks. 3rd guy replaced my radiator & gasket. 4th replaced damaged windshield washer reservoir. Two weeks later coolant still leaked out -mid winter- so I have no heat. After I choose which of the knuckleheads to do the job of replacing hoses I’ll return here with an update. Joke is - How many mechanics does it take to change a hose 😂

[@JesusLaperra-p3k]

I'm not sure around 20 ??😂😂😂😂😂😂😂😂😂😅😅😅😅😅

[@madrabbitt]

While my 16 is newer and seems to have different designs for the fittings (haven't cut them off yet, need to get the replacements first) this video helped me narrow down where the leak was, which was SUPER helpful, thank you.

[@salomonguzman6]

I just bought an Avalanche and that was the first problem. Good thing I found this video, it was already worrying me.

[@russjcameo]

Thank you, I just performed this repair on a 2011 Silverado WT before watching this, and you've show a better and more comprehensive tutorial for how these quick connects work than any of the shorter videos I watched beforehand. I also had to use some serious elbow grease to insert the quick connect removal tool, and it was "a bit of a pain".

[@WrenchingWithKenny]

Thanks for watching. I'm glad I could help. Keep wrenching 🔧

[@thomask4836]

I wish I had that Astro clamp tool when I did my Saturn radiator. I used a pair of channel locks and I also used a word that kinda rhymes with "Astro" a real lot. It looks like there is a set of those hose fitting release tools in my future! Thanks Kenny!

[@WrenchingWithKenny]

They make life better lol . I've had several different styles over the years and these are hands down my favorite. I actually gave away my Snap-on ones several years back . They were no where near as good as these are . I've had them for about 4 years now

[@louiestanley300]

Thank you I just replaced the heater assembly on my 2009 GMC Sierra 2500 w/ the 6.0 gas because of this video..I did not use the multi color tool set like you have and I got the cheap $5 white plastic set from HF but I highly recommend getting the tool set this man shows in this video..thank you for the video sir

[@fludrbywest3886]

Perfect awesome video thank you so much ❤🎉 I have a Chevy Silverado -4.8L -2007 and it looks the same !

[@joemiroddi9067]

Thanks Kenny, you saved a working stiff a couple of bucks...

[@leroybailey423]

Thank you Mister I just changed mine after watching your video 👍

[@WrenchingWithKenny]

Glad it helped !!

[@toenails.]

I got so mad at mine I took a big channel locks and broke the heater core tubes right off. Screw the heater.

[@WrenchingWithKenny]

Been there on other things lol

[@calebduncan1697]

My heater core hose kept blowing off on mine.And I just took the hose and looped it to itself and did a heater delete.Since the heater didn't work anyways, the next owner's gonna be real confused.When he sees the heater hose looped into itself😂

[@jiminykripes4937]

Can't do that in Wyoming it gets too cold and the windows ice up in no time

[@redefiningmyself8598]

Hey thanks for this tutorial, Kenny. You just saved us from a trip to the mechanic 🎉😊

[@thecuss6817]

We had one of those connectors break while Mrs. Cusser was towing horse with 2005 Yukon; temporary fix was to cut at the connectors and connect the two hoses together. Yes, I bought the special disconnect tool to fix properly. Not the best idea, those plastic connectors there; a computer search showed the break routinely....

[@WrenchingWithKenny]

I've done that also to get someone back on the road in a jiffy

[@Yixdy]

Hey there! I thought the inlet and outlet were aluminum bonded to the plastic, thank God they're removable fittings! It's a cold winter out here, wasn't looking forward to doing my heater core or freezing myself out!

[@TheGregWallace]

Comment.... I knew I had a leak and I finally found it tonight and mine is leaking in the same place.... I just new someone on the youtubes had a video..... Mine is a 2004 chevy silverado 5.3..... Thank you for the info.

[@johanvkjr]

one of chevys brilliant ideas.

[@rogerrolfe8114]

Must be the same GM design engineer that have all the dash lights soldered in my GMC truck so the dash or instrument panels have to be sent out to have the bulbs changed. If the dash with the speedo and tach are sent out the truck won't run because the computer needs the tach signal to run. Some engineers make some good designs but that engineer went to the school of F'n stupid along with engineer that approved that idea.

[@northpoint1039]

I hate those GM hose clamps. They get old and lose their tension. Even if they are new you need to get them in the right place they where before or they leak. They seem to be really expensive too. On my lucerne I replaced the radiator and couldnt get the hoses to stop leaking coolant. So, I got rid of the GM clamps and went to the faithful screw type clamps. For added help I used some gasket sealer around the inlet and outlet of the radiator. One of the GM hose clamps the catch on it broke off. I had to cut the darn thing off with my dremel wheel cutter. Thats been about a year ago now and its doing great. Those plastic fasteners for the heater core are a pain also. The plastic gets brittle and never seem to work right for me. I have actually just planned on replacing them no matter what and just cut off the old ones. Enjoying your videos. Thank you!

[@WrenchingWithKenny]

I've always hated these style clamps too . Such a pain !! Thanks for watching !!

[@332ARA]

I've seen Aluminum quick release fittings available. Any downside to using those?

[@-jimmyjames]

If you don't have the tool. Snap a hacksaw blade in thirds or even half. Either by hand or using lock pliers you can get them off n a couple min by sawing straight along the side.

[@1Turnatatime]

I just crimped mine, the one on the left just blew off. Was gassing it. Can I just leave it crimped until I buy a new hose. Not sure what that one is for. The heat in the truck or A/c? Happy to have found this video, hope the special tool isn't too much. Looks like it won't break the bank

[@dbspecials1200]

A lot of handy people complain that they can't work on their newer cars anymore, and this is one reason. it's not always the electronics. when new fittings are invented a remedy for those is also needed. fuel lines are another great example. some people will give up on repairing it themselves, or they might break something. you might buy a tool that works only on Fords, then you might not have the Ford anymore, but a collection of specialty tools. I say save em.

[@adamboone1260]

Your a genius, thank you

[@WrenchingWithKenny]

Thanks for watching

[@BadReligionQL]

Those are fun when you are pulling the intake or generally working around the area bump it, and snap that brittle thing off.

[@WrenchingWithKenny]

I've done it before .. They do get quite brittle

[@discoverlight]

It happened to me I was going to get the fuel rail off and I barely touched it to make way and it snapped right off 😠.

[@user-fw6eg3hc8f]

@@discoverlight More convenient than on a road trip

[@glennmanchester5696]

Did a motor swap on an 08 Silverado and of course in the midst of that broke one off I'm glad its fixable and not like well got to change the heater core now whew

[@ArmandoMorales-z7v]

My truck just blew coolant everywhere out of no where my radiator looks beat as hell jb weld everywhere.. has me worried I was able to make it home I bought a new radiator for 300$ hopefully everything goes well. As soon i put coolant in it spills right on out. My temp was at 210 for under 3 min do you think I’ll be alright ? Truck starts up fine

[@altaft9587]

I dont even have a shop right now and I have rolls of all different sizes of hose fuel lines and hydraulic .take it from a 40 plus year master mechanic I built my first engine when I was 10 in 1980 1965 mustang 289 stroker

[@ProduktOfEv0lution]

great video!

[@discoverlight]

Thanks for the tips.

[@ermac9647]

Is there an o ring inside of the first old quick connect closest to the engine? I have replaced hose but still slowing leaking from connector

[@qsurface3799]

I think I’ll cut the plastic connectors and just hose clamp hose to pipe eliminate the problem of the plastic cracking

[@rickwidlund3512]

Thank you again.

[@scuba422123]

hey kenny the next time you do an oil sender dont even get close to them they turn into glass! i have the astro i think it sucks, maybe yours is updated ?? the shop has a snap on and its great

[@WrenchingWithKenny]

How weird is that . I gave my snap on away because it was just terrible lol . But that was several years ago .

[@steveleston1848]

cant we ditch the quick connects an shove the rubber tube over heater core in an out?I hate that when stuff drops down inside engine I've spent more time looking for crape than the initial job takes.

[@Jay-vj1km]

Only my right hose is leaking. The left one is fine. Do you recommend that I put new fittings on both hoses? In your video you repaired both fittings so I didn’t know if you had a leak in both hoses or if you were being proactive by repairing both.

[@Trip1443]

Hell. Yes. Plastics are like lightbulbs but more expensive when on the cooling system. You can "save" 12 bucks buying one side but have to pay for a tow because the other side decided to die a month after in the middle of nowhere. Like a turn signal bulb if one has gone out, the other one isn't far behind.

[@rollymignacca4821]

When changing that hose ,must you lower the coolant in the radiator. Thank you Sir for your time and the video.

[@Blue_Collar_Hunter]

How will you know if you have a leak here? Will I see coolant? I’ve replaced the whole cooling system. Water pump, radiator, all hoses, thermostat, overflow tank w/ new cap. And yet I still have a leak I’ve checked all hoses and connection points. I even did a block check and oil change to check for a head gasket leak, nothing, oil is clean and the block test turned up nothing. It’s also a 2005 Silverado with a 5.3. If it’s leaking at the heater core hoses can I see the leak if the motor is up to normal temp 220° roughly? Will I only see this leak if it’s cold? The only experience I have with this issue is when they get brittle and completely break dumping all fluid. Please help I’m at wits end. I have to add coolant after every drive, if the AC is on I can smell coolant. I do not have any visible signs of coolant dripping, just that my tank is down 1-2” after every time I drive the truck.

[@williecosgrove]

No lies with you Kenneth , straight as daylight

[@WrenchingWithKenny]

Thanks man !! I try to be completely sincere and honest showing what I go thru

[@dannydossett9057]

Kenny you didn't say which place to get a 5/8 to 3/4 heater hose. I am about to do that same job on my 2008 sierra.

[@heidirudnik3416]

What if the leak is behind that fitting on the right hose?

[@Spentbrass42]

just had my right connector finally fail on me while taking a buddy to get a car which drowned my #8 ignition coil. for now till i get paid and get the tools got the coil replaced and shoved some shop towels under it to catch the coolant for now. honestly was stumped till i looked it up and then it hit me that this was the problem.

[@leonelreyna48]

Mine is over heating because of this leak. Going to fix it asap .

[@dens9057]

That very same fitting cost me over 200 bucks cause it broke 5 miles from home so a tow snd shop time for a 10 dollar part.

[@FelNoobs]

Hello father How are you father Why not connect the hose directly to the heater instead of this piece of plastic that often breaks ?

[@do7hemath937]

Great video, but my leak is down low, centerline of the truck.

[@paulferrara9079]

Way to “Rube Goldberg” a heater core assy Chevy!! 😮

[@Beanszo]

the left hose connector broke while I was trying to get the right end off, crazy, now its gonna be a pain

[@jessejames7140]

I took all the plastic shhh off and the cut the hose a little and then got metal hose clamps and slipped it over the metal of the heater core after all that plastic was removed. $2 fix

[@UccelloLibero86]

Can you just connect the bare hose right to the firewall with a clamp instead of using the fitting?

[@WrenchingWithKenny]

I have seen people do that, but there is nothing for it to grab hold. There is a good chance that it will blow off eventually. Keep wrenching 🔧

[@user-fw6eg3hc8f]

@@WrenchingWithKenny Nah it's only like 15-20psi, you can almost hold that with you finger. Just tighten a clamp down it will be fine. If it was an oil/trans line then yes flare the line double clamp it

[@TheRaystevenson]

Can you do a video of how to wash an engine. Power washer or just a hose or what

Bro spliced a coolant line for a CUSTOMER 🤦🏼🤦🏼🤦🏼 young fellas don’t do that unless it’s your vehicle and you don’t care. Never halfway do something for a customer. If it takes more time then it takes more time but atleast it’s done correctly.

[@altaft9587]

Just a fyi the plastic ones are shit I spent a whole 15 bucks got the aluminum one instead of plastic garbage .and there is way better tools for that than that harbor freight crap you bought I have nice metal anodized ones

[@KennethCavins-w2t]

😂😅😂

[@hummingbirdoasis6260]

Do yourself a favor and do away with these quick release fittings altogether. There is no benefit to having them on your vehicle, they will only wear out later. Install standard T's and or clamp hoses directly without quick release fittings.

[@levicallis459]

Yep , did exactly that . The special tool was terrible , so I took some mini snips to it , then just directly connected a hose to the heater core . Idk why none of these videos are saying this. The store wanted 61 for the setup , and I paid 8 for the hose

[@garyrife5313]

Gm engineers go out of their way to make. Auto oownershiippp suck !

[@rexsmith9176]

Anybody who says it's a 30-minute fix is b******* I bought two sets of tools and I still took me a half a day they've got the heater core too close to the top because of the way the motor sits back you can't hardly get your fingers in there to compress the tool inside don't think you're going to do it 345 minutes took me a half a day

[@dustinclark8107]

Bro just break them off and use hose clamps😂
