Great video, about time a good A/C restore video without all the extra chit-chat about other issues. Just straightforward getting it done. Thank you, now on to me doing my Silverado.

[@ForceBuilt]

Thanks for the input! Good luck with your Silverado!

[@markblandford9346]

Thanks for sharing, Steve. I always look forward to any content you put out. Hopefully you have fully recovered from your surgery. It looks like it anyway!

[@ForceBuilt]

Thank you Mark! I always look forward to hearing from you! Yes I have recovered almost 100%. Thanks!

[@kennethcox9688]

I just did this to my truck and now I see your video! I love it. Perfect! 😂

[@ForceBuilt]

Thanks Kenneth!

Thank you for the video. This helped a lot. 👍🏾👍🏾

You are welcome! Thanks for watching!

[@fredhelmecke6073]

Glad I found this best one I found....Thanks.

[@long-jeep]

At my age cold A/C isn't a luxury is a necessity. 😆 I appreciate the fact that you'll take on just about any repair. Nice work!

[@ForceBuilt]

Thanks Long Jeep! Sometimes I don't know when to quit haha..

[@geovannimurillorodriguez4186]

Sir thanks for the video now I’m going to put my hands to work on my ac. I am in Florida and I need that ac. Really bad. Thanks for the video. 💯💯💯

[@ForceBuilt]

Thanks for watching and good luck!

[@armandomiranda7244]

Thanks a bunch! Nice truck

[@SuperDave21]

I'm getting ready to do the same thing to my 91 C1500 SWB. It's been growling for a couple of years so I'm changing the line sets, condenser , drier and compressor.

[@ForceBuilt]

Good luck SuperDave!

[@jaydee9630]

Great video Steve! My 94 c1500 just had a new crate motor transplant and haven't had ac working in the truck for 15-20 years now and ready. Summer in Texas is difficult to survive in and your video has me excited to get her cold again.

[@ForceBuilt]

Thanks for that Jay! Glad you found it useful. Good luck with the A/C Project!

Great video! I've got a '92 K1500 that I need to replace the entire A/C system in and this definitely helps.

[@ForceBuilt]

Thanks ducktapepilot! Love your KZbin name. Good luck with the A/C!

[@ducktapepilot]

@@ForceBuilt Thanks! Quick question; did you need any special tools for fittings or anything? I was thinking there was a fitting in the A/C system that required some kind of special tool but I may have dreamed that lol.

[@ForceBuilt]

@@ducktapepilot just wrenches is all you will need.

[@ducktapepilot]

@@ForceBuilt Awesome, thanks!

[@FrmA.Townnn]

@@ducktapepiloti got the same truck but i seen that some compressors have 2 wiring connectors on it but the one that came with the truck had just the clutch connector is that all it is to it?

[@mitchharrison435]

It looked like you were charging thru both the high and low side with the engine running. Only use the low side with the engine running. Good job getting the AC fixed.

[@ForceBuilt]

You are right Mitch! Thanks for pointing that out. Thanks for watching!

[@williamb454]

Only charge thru the suction side and leave the other side closed? Cuz I'm going to do it myself and I gotta get it right!!

[@kylesmith75323]

Yeh only the line that is going to the dryer is going to be open for those watching. Thanks for the oil measurements!

[@reggaeshark9854]

Brother you sound like a character from brickleberry 😂

I love your grill! Where did you get it. My truck is a 93, but I want to replace the grill with a 98 looking grill.

[@ForceBuilt]

We got it on Amazon. It is not a bolt right up conversion like I thought is was for our 91 truck. We had to make 2 brackets and modify the filler panel between the grill and the bumper. Here is where I talk about the grille more. Start at the 6 min mark, kzbin.info/www/bejne/hHS6npxsopyDhKM

[@letaloudone]

You lucky the xan did not blow up in your hand. You opened the high side valve while charging. Never ever open the high side while running.

[@ForceBuilt]

Yeah, I realized that later and don't know what I was thinking. I did get confused. I for sure did that part wrong. Thanks for watching!

[@sntruck]

Yep just replace everything so you don't waist time wondering if you can use the same old parts.

[@roymedina4729]

Did you convert it from R-12 to R134A refrigerant? I have a 1990 Chevy C1500 and it’s low on refrigerant just wondering what can to buy.

[@ForceBuilt]

Yes I did convert from R-12 to r134a. Thanks

[@MarshallSmith27]

Question for you. My 1993 had propane and the original compressor. It went out 2 weeks ago and I replaced everything but the hard lines and the evaporator core in the cab and went to r134a. I'm just not getting cold air. 60º out the vents and its 82º today and 75% humidity here in alabama. my readings on the gauges is 44 low side and 212 high side which is great. I even took the blower out and cleaned the evaporator core. 60º isnt cutting it and all the money I have spent is not making me that happy what could I be missing?

[@ForceBuilt]

Did you pull a good long vaccuum before filling with 134a?

[@MarshallSmith27]

@@ForceBuilt I did I got it to 29" of mercury with a pump from oreilly

[@ForceBuilt]

@@MarshallSmith27 OK, Just asking trying to figure out what is going on. Did you let the pump run for a long time? That will remove moisture from the system. Moisture will affect cooling.

[@healedbypitbulls6995]

So I did the same and it was perfect and nice and cold. Then I drove it around the block only. Now the high side is high steadily going 350+. Can u update on this truck? Please

[@ForceBuilt]

Everything works as it should. The biggest problem I see is the compressor is noisy at anything below 1k rpm. Really annoying. I would check your orifice. If it is blocked that will cause high pressure to be too high. Thanks for watching.

[@user-nm2ib4jx2j]

Curious, did you use a spanner wrench to rotate the clutch?

[@ForceBuilt]

No I didn't. That is a good idea though. Thanks for watching!

[@bhwjrproductions]

You swapped out that old tube and fin condenser for a nice parallel flow unit, looks really good on your truck. Is your AC still running nice and cold? I just did the same AC swap on my Gbody car.

[@ForceBuilt]

Everything is good. My compressor is noisier than I would like at low rpms. If the engine drops to 800rpm the compressor is loud. Is yours like that?

[@bhwjrproductions]

@@ForceBuilt I have a 5.3 LS truck engine with a new DENSO compressor thats mounted low on the passenger side like it fit in the truck. The engine idles at 500 rpm and I can’t even hear the compressor running. My dual exhaust and flowmasters aren’t the quietest either. I replaced every ac component and like you my ac seemed to have good pressures with less than the amount of 134a than I thought I needed.

[@leoyanez8632]

Did you need to put a pressure switch on your compressor?

[@ForceBuilt]

No, I reused the one that was already on the dryer accumulator. 1:47

[@sirleadsthetroops]

where do you add pag oil if the compressor is a bit low? haven't used my ac is 10 years lol

[@ForceBuilt]

Just add it to the hole where the AC lines bolt to the compressor.

[@SeriouslyAwesome]

you could probably add it directly to the yellow line right before it sucks up the freon can

[@ducktapepilot]

Thinking about buying this kit for my Chevy. Curious how well it's held up now?

[@ForceBuilt]

About to replace the Compressor. Very noisy now and not cooling like it was. We have the lifetime warranty. Glad we do. Good luck!

[@gerardolopez5875]

@@ForceBuilt@ how long did it last?? The compressor

[@ForceBuilt]

@@gerardolopez5875 It lasted roughly a year. I am doing a video right now concerning the repair. It was still cooling but VERY loud. Metal shavings are in the orifice tube.

[@tj-hero]

i wish that you wash the radiator for better air flow

[@ForceBuilt]

Yeah, but I have to change it anyway. I have a small leak I didn't know about. Air flow incoming! Thanks for watching!

[@clinteast7476]

How much were all the parts total cost? thanks in advance.

[@ForceBuilt]

$400ish to replace everything except the evaporator.

[@clinteast7476]

@@ForceBuilt thanks

[@ezeduke101]

sO did yOu add a little more Freon like yOu suggested or yOu just left it alone satisfied with two cans?? It was blowing cold air like with just tHE two cans..

[@ForceBuilt]

Yes it was blowing cold with just 2 cans. I only did the 2 cans but I think it calls for a touch more. I bought an extra can but it was doing so good, I never added it. If you want to add a little more, it will not hurt anything. Just watch your gauges and don overcharge the system. There is no chance of overcharge with 2 cans. Thanks for watching!

[@ezeduke101]

OKay, I got mY two cans of Freon & liquid die today.. I have a new compressor & dryer with orifice tube.. gonna see if this works without getin’ ’ a condenser.. Thanks

[@ForceBuilt]

@ezeduke2328 good deal! Good luck
