I watched a few tutorials and they all had the 2 piece cover when you pull the core out. Finally found a one piece tutorial. I was stuck on the rod n didnt know. Keep up the great work

Glad I could help

@heatherjane74 4 года назад

Glad you got that fixed! Now I don't have to refuse to ride along when the weather is cold.

Great video. Nice to see just the way a working guy keeps our old square bodies on the road. Not restoring, just a driver. Good job.

Thanks.

Thank You Bro. The air box can be a little overwhelming at first.

Well done 👍 it’s almost impossible to take it apart without braking the brittle plastic 😂😂

LMC makes a great catalog you can get every little piece you can think of for that truck specific catalog LMC my favorite for my old buddy 79c20

@mr.badluck8004 3 года назад

Thank you for the vid. I have a 73 that needs a new heater core and want to do myself.

@SquarebodyStuff 3 года назад

Good luck with it. Take your time and enjoy it.

@mr.badluck8004 3 года назад

Thank you. Since I have you on the horn. My 73 stalls after the rebuilt. I had the Rochester and transmission done too. I like how you explain easy to understand.

@SquarebodyStuff 3 года назад

That could be any number of reasons. Check for vacuum leaks, verify ignition timing, adjust idle speed.

@joeh2085 2 года назад

No need to remove the rod for the blend door. You can just spread out the sides of the box enough to clear the rod ends and the box slides right out to get to the heater core.

Good stuff... love the bluegrass.. I got in my 84 last week and a mouse or mice had eaten a whole bag of cough drops.. funny stuff . Wonder if their breath smelled good lololol!!

Lol

@Austinadcock 3 года назад

If you are in a pinch and just need the heat and you have the A/C disconnected as you do on this particular truck you can run hoses to the evaporator core AKA heater core 2.0 lol my 74 crew cab ramp truck is like that currently has been that way for about 8 years....

@SquarebodyStuff 3 года назад

Heck yeah. That's some good stuff.

@briang4470 3 года назад

I bet you get amazing heat that way,lol the evap has alot more surface area than the heater core so if your willing to loose the ac then it will definitely work but if you live in the south like me there is now way I would ever give up my ac, I spent so much time and money putting my ac back together that theres no way I will ever get rid of it.

@zachariasbrink9540 3 года назад

lol Dead Mouse I like it !!!

@pontiac6978 3 года назад

This is even easier if your truck doesn't have A/C like my 81.

@SquarebodyStuff 3 года назад

Yes sir, non AC cabs are much easier.

@gentilejoshsaved1646 3 года назад

Hello, great vids. I got one with absolutely no heat. Could it be water pump? I mean no heat at all ice cold air. Thanks

@SquarebodyStuff 3 года назад

I'd guess the heater core is blocked. If it was the pump, you're engine would overheat.

Any about doing plate lights

@l.holland9968 Год назад

My 83 is blowing cold air. I manually opened the doors but it's like ice air 🥶 what you think, thermostat or core? Help 🥺

@budmoore8144 3 года назад

Kinda ironic i watch about all of your videos and this popped up today. This morning i got in my blazer and no blow out the defroster i tore into it and the plastic piece was broke so i put a used one i had in it. My question is does that back tang on that thing need to go down in that slot ? My blow is better but still not great

@SquarebodyStuff 3 года назад

The end with the hole stays on the outside. The other end should have a tab that hooks through the hole in the door.

@briang4470 3 года назад

If your careful, this is not a hard job, the hardest part is getting the inner fender out. When I did mine I thought it was going to be a nightmare but it only took a couple of hours and was not a bad job at all.

@markbly7062 2 года назад

no one sell brand new copper brass heater cores for squarebodys without air conditioning

@bullardfarms Год назад

I had to replace the heater core on my c10. Now, and probably before too, the air conditioner leaks condensation in the cab and wets the carpet. I know its not the heater core because I disconnected it to see. When you stop driving, condensation pours out outside. I don't know if it drains while driving or not. Do you know how to fix this? Thanks!

@SquarebodyStuff Год назад

You might have to pull it back apart and see if the drain Is plugged from inside.

@bullardfarms Год назад

@@SquarebodyStuff it's possible, but I stuck something in from the outside and it didn't seem like it was stopped up. Thanks for the help!

@martinolivas319 3 месяца назад

Hey brother I’m just wondering if it’s possible to stop my 76 c10 blower motor from pulling in outside air. My exhaust doesn’t leak but at lights it still pulls in the surrounding exhaust smells is there anyway to prevent the blower from pulling that in or closing that off

@SquarebodyStuff 3 месяца назад

Disconnect the fan is the only way I know of. Or run your exhaust further out the back.

@martinolivas319 3 месяца назад

My exhaust dumps behind the back tires, but at the traffic lights it will pull in exhaust from the vehicles around me , I don’t want to disconnect it as I’m usually running the ac

@SquarebodyStuff 3 месяца назад

If you run the ac on max ac, it should recirculate the air inside the cab and not pull from the outside

LMC has heater cores. Not sure what material they're made from.

@SquarebodyStuff Год назад

I'm not sure either, but I think they're aluminum.

@SquarebodyStuff Where did you buy the plastic piece for the vent door you said you bought several of? Got to replace my heater core in my 86 K2500 and would like to try and get some in case mine is broke.

@SquarebodyStuff Год назад

If I remember correctly, it was classic industries.

@SOU6900 Год назад

@@SquarebodyStuff I looked but I couldn't find them though I guess I should be glad since mine was still good. 2 questions though. What is the factory core made of, and is there supposed to be a gap between the box and the duct that goes to the defrost vents?

@SquarebodyStuff Год назад

Factory core is brass, and there shouldn't be a gap between the duct work.
