Oh man, I'd hit the like button 1000 times if I could. You just saved me a lot learnin curve hassle. My blower motor was pretty easy to figure out on my 2016' 579. Turns out heater core is almost as easy. Thanks a million.
Thank you Big Jon for your service to this country, and thanks for this video.that quickly showed me this is a job I can do myself. I'm just a steering wheel holder for a dump truck outfit.
Big John!! Thanks for this video man, very helpful and straight to the point 👍🏻 had coolant coming out of the ac drain hose today 6-16-21 started doing my research and came across your video and was able to troubleshoot the problem and fixed it, Thanks man!!
Hi Jon. What year is your truck ? I have a 2016 peterbilt 579. I keep having leaks from the radiator hoses and I’ve had them replaced but still the same thing keeps happening. I tried going to peterbilt to get a diagram of what the hoses should look like but they can’t find anything. Anyway you can help me ? I just need pictures of what the radiator hoses are supposed to look like on the truck. Thank you.
Hello I just busted mine and it’s slowly spewing antifreeze. I can’t replace until next week, can I temporarily connect both hoses together so I’m not smelling antifreeze inside cab. Just long enough to get it replaced. I then can take it out and get a new one without paying a mechanic.
Wassup Big John. Just found you. Good video and great info. To you and anyone on here, I have a 2016 t680. Its wintertime. Defrost and heat are blowing out cold air while im driving, but warmer while im sitting still. If I put it in recirc, it comes out warmer, but won't recirculate on defrost. I guess that's from the factory that way. Not looking forward to North Dakota this year. Also,, I smell coolant sometimes but I see no leaks. I know thats a lot of info.. Just wondering what you think it might be. Sleeper heat is working properly. Thanks.
@@BigJon is that something I can fix without replacing the whole unit? Where is it located? I'm gonna take off the blower motor and change the filter behind it. Im unfamiliar with the area. Im also gonna replace the core.
Its located in the main ac unit behind the dash. When I had to fix mine I did it myself it was a pain and you need an extra set of hands to help cause you have to pull the dash out
Im pretty sure I bought a 579 and I drive the same 579 every day but I did have a 680 and yes they are the same and just to be clear the 579 is the one in the video

Thanks for your support and I'm glad the video helped
Awesome video!
Strait to the point!
Most guy's would make this a 45 minute video, when your 5 minute video is plenty good!
Never ending.. Working on these trucks
Man thanks for the video. Saved me $220 on labor.

Mine was a 2014 but I no longer have it. Sorry I can't help.
By any chance you have the part number. Great video my friend, blessings

Yes you can connect them together, but obviously you wont have any heat if you do
I live in Texas and it’s warm. Should be fixed by Tuesday/weds thanks for the support
Dude love the vid keep it up

Most likely you blend door isn't working properly

Its mainly the labor your paying for at a shop the blend door is $20 and the actuator is $60 on amazon but gonna take 10hrs of labor to complete
Thank you for the information. I sure appreciate it.
Sweet. Thanks
Great video
Thanks!
No problem
I made an attempt to do this myself and put my grips on pulled inlet line off and coolant still came flying out.. Wtf.. 😆😆😂
Some will come out but you got to make sure to clamp the lines tight
This is not peterbuilt 579 you are working on kenworth t680 lol but thanks for video I needed to changed that
Im pretty sure I bought a 579 and I drive the same 579 every day but I did have a 680 and yes they are the same and just to be clear the 579 is the one in the video
They are same
That’s too new of a truck to change parts like that already..unlike my 359..is expected
It was leaking and fogging my windows... it was bad
Don't vice grip your hoses. You just bought a heater core and created a reason to buy new hoses.
What would you suggest then ?
Thank man
