Old GM Cars 🚗 really gold 👍👍👍👍👌👌💪💪💪💪💪

[@Anth4044]

THAT WAS FREAKING CRAZY HOW DIRTY THAT OLD ONE WAS 😨😨😨😨 Thanks for great video wow I really learned alot from this awesome video 👍

[@BROTHERSTruckPartsTV]

Yeah it's nuts to imagine how inefficient these systems can become after this many years.

[@marquis2428]

Post a link where I can get that box because I have a 80 Malibu that the AC was completely deleted and I want to reinstall everything

[@vulgarhyena9616]

Wow that thing was dirty! I need to do my heater core in my 70 (inside box) and also my blower motor sounds like a child screaming, looks like I better clean that evaporator out while I got it apart!

[@BROTHERSTruckPartsTV]

You'll be amazed at how much better it blows inside the cab once you clean it out!

[@GenX_-um2ct]

Im doing an LS swap on 83 S10. The right side of the fiberglass housing was crack. But my plan was an AC Delete anyway. I have removed the damaged panel and the evaporator, would like to maintain factory heat if possible. Do they make a bypass without deleting the heat too? Even if I had a replacement panel with AC, I could probably seal it up to make it work. Any tips? 3D printing maybe?

[@EQtown]

How did you get the bottom hidden screw out? I can't see down there so can't get a tool on it

[@garyhardee2720]

Just watched the video. Excellent. Can you clean the dirty evaporator with freon still in system?

[@BROTHERSTruckPartsTV]

Sure, as long as you don't disconnect the lines

[@rayjohnson7886]

Do yall still sell the gasket kit and one question can you give me the vacuum information to the black round canister on the left side of the cover of the evaporator thank you.

[@HLM-music]

where do i find the gasket kit

[@rayserobinson622]

where is the expansion valve located?

[@darkwar12345]

Wondering why you have fuel hose wrapped around the drier? Is it to keep the fuel cooler since the drier does get cold?

[@BROTHERSTruckPartsTV]

Yep, old school trick to keep fuel from boiling on hot days

[@1bad69xss4]

What’s the putty like stuff on the outside of the box where the tubes come through? I don’t know if this one had it but it’s like a sealant but more so a putty.

[@BROTHERSTruckPartsTV]

It's actually a thick tar-like tape, but eventually just melts into a putty of sorts. You can find it at the local auto parts store normally.

[@1bad69xss4]

BROTHERS Truck Parts Ah, exactly!! What’s the name of it?

[@BROTHERSTruckPartsTV]

@@1bad69xss4 We found it for sale on Ebay, here's a link: www.ebay.com/itm/Black-Cork-Insulating-Tape-or-Prestite-Tacky-Tape-for-A-C-Expansion-Valve-AC-36-/122658942584

[@clearedhot6146]

I'm replacing condenser on 67 impala with universal condenser, can I use any newer compressor with this model evaporator?

[@BROTHERSTruckPartsTV]

You should check with the manufacturer of the compressor you plan to use to confirm compatibility.

[@tylerd.5541]

Great video! Do you guys sell any conversation kits. I have a 1984 C10 that's a non AC truck that I want to convert over, thanks!

[@BROTHERSTruckPartsTV]

Yessir, check out your options here: www.brotherstrucks.com/Complete-A_C-Conversions/products/2330/

[@tylerd.5541]

Thank you! I will be checking it out!

[@mjkempf14]

Newbie here. Will this be under pressure when it's removed, and will I have to recharge the system with freon once I have it all back together?

[@BROTHERSTruckPartsTV]

As soon as you disconnect any of the fittings it will need to be recharged, and it will be under a small amount of pressure if it still has refrigerant left in the system.

[@delfinogarcia6169]

Cuánto tiempo lleva para auitarlo

[@BROTHERSTruckPartsTV]

@@delfinogarcia6169 Se trata de un trabajo de 5-7 horas.

[@jpearson311]

Can these old systems be converted to R-134A/R1234yf without removing the entire AC system?

[@BROTHERSTruckPartsTV]

Definitely easy to convert to 134-A, not certain about the other standard you mentioned. The truck in this video is a 134-A conversion.

[@jpearson311]

@@BROTHERSTruckPartsTV Awesome thank you!

[@BROTHERSTruckPartsTV]

@@jpearson311 Our pleasure!

[@9andrethegiant1]

So I ended breaking a piece of the evaporator core case where a bolt goes through, where can I buy a replacement core case? It’s been difficult to find

[@BROTHERSTruckPartsTV]

You'll likely have to pick one off a donor truck. They just aren't available as a reproduction at the moment.

[@daviddixon7613]

If you have all the pieces, check with your local body repair person. I had someone to repair the fiberglass on mines.

[@rodneys9805]

when does the heater core video come out......keep me posted lololololol

[@BROTHERSTruckPartsTV]

Actually it's coming very soon. This same trucks heater core just started leaking. We've already got it on the schedule for a video.
