My heater became really weak, not very much heat. Flushing the heater core solved the problem. Hose pliers: tinyurl.com/yxa... Hose flush tool: tinyurl.com/y5o...
Omg. Wow. It worked. In fact, the heat is melting my face now. Didnt cost a thing. But yeah it worked after i put everything back together!!! 2001 Silverado 1500. THANK YOU🤘🤘🤘
That's what I was thinking. Then I decided the flushing the heater core was a lot easier and if it didn't work, I would only be out a few minutes work.
should i do this if my heat blows cold all the time even when the motor is at normal operating temperature ? or does it sound like i have other issues ? and can you switch the hose around and flush it flowing in the way it circulates coolant ?
Its part of the air system bank 1. The original hose cracked and that is the replacement. This video shows bank 2 of that system. czcams.com/video/ZUPwTWGtUn8/video.html

You're welcome!
I have a 2000 Silverado as well, thank you much for the help, no heat in my truck now
Great video! Easy job! Didn't cost me a penny. Just ran some water through and my heat is flowing again.
Wow, I've been without heat for years, gonna give this a shot.
Definitely doing the is before winter season comes
1999 silverado 4.8l and it worked perfect and i didnt even use any fancy hose jig
Just flushed the heater core on my 2001 Sierra, perfect.
Thank you sir! I’m gonna try it out and hopefully save $1000. Can’t believe the design on these heater cores 🙄
Thanks man , it works great now 👍
Thanks for the links as well, hopefully you receive revenue from the purchases.
Think the id is 5/8
Gonna have to try this before tearing the whole dash apart to replace a heater core hopefully it will save me alot

Yes it helps a lot where can you find those pliers?
I got them from Amazon.com
What are they called chevy hose clamp pliers?
@@austinricker5990 I think you are referring to these: tinyurl.com/yypo83rg
Why not swapped hoses so the coolant runs the coolant diffent then as it was designed it can only improve as it breaks more gunk loose
Because all that gunk will end up in the engine coolant system.
Will this work for the 2007 to 2003 silverados too?
Would the hoses be located in the same place for a 2003 GMC Yukon? Thanks.
I don't have a Yukon so I can't say for sure.
Yeah, should definitely be in the same place, pop the hood and look on the passenger side of the firewall.
Yes it would these both use the same LS motor
Would a clogged core cause the motor to overheat?
It shouldn't unless its not just the core that's clogged
Will this maybe fix the syrup smell coming from heater core or could it possibly be a heater core leak
Sounds like a leak
So right IN , left OUT... which one is the straight hose? And which one goes to the "Y" hose?
I don't understand "Y" hose. There are no Y's
They y hose goes to the cold or left outlet
@@vendter I'm sure she's talking about the cold hose. It makes a y at the engine and the bigger portion of the hose goes to the reservoir
should i do this if my heat blows cold all the time even when the motor is at normal operating temperature ? or does it sound like i have other issues ? and can you switch the hose around and flush it flowing in the way it circulates coolant ?
Flushing the core is the easiest fix. Do not switch the hoses.
Can I use air instead of water? (An air compressor or would it mess with or break something
I would use water only. And low pressure at that. Anything above 10 psi could damage the core.
You reverse flow ?
yes
In this video is it a reverse flow?
@@davidferguson9814 yes
Do you have a link for that hose adapter or a name?
I hate to post links because they break pretty quickly. Search for "heater core flush kit" and you should come up with what you are looking for.
Vincent Endter got it. Thanks
What is that line with the blue going into it?
