Thanks you!
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.
Thanks for the input! Good luck with your Silverado!
Glad I found this best one I found....Thanks.
Thanks a bunch!
Nice truck
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!
Thanks Long Jeep! Sometimes I don't know when to quit haha..
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!
Thank you Mark! I always look forward to hearing from you! Yes I have recovered almost 100%.
Thanks!
I just did this to my truck and now I see your video! I love it. Perfect! 😂
Thanks Kenneth!
Great video man I appreciate it made it look easy
Thanks a lot!
Great video!
Thanks!
Thanks for this video, its very informative.
Thanks a bunch!
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. 💯💯💯
Thanks for watching and good luck!
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.
Good luck SuperDave!
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.
You are right Mitch! Thanks for pointing that out. Thanks for watching!
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!!
Yeh only the line that is going to the dryer is going to be open for those watching. Thanks for the oil measurements!
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.
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.
Thanks ducktapepilot! Love your RUclips name. Good luck with the A/C!
@@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.
@@ducktapepilot just wrenches is all you will need.
@@ForceBuilt Awesome, thanks!
@@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?
Yep just replace everything so you don't waist time wondering if you can use the same old parts.
Brother you sound like a character from brickleberry 😂
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.
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!
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.
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, ruclips.net/video/NCWmi6m7PNA/видео.html
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.
Yes I did convert from R-12 to r134a. Thanks
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?
Did you pull a good long vaccuum before filling with 134a?
@@ForceBuilt I did I got it to 29" of mercury with a pump from oreilly
@@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.
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
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.
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.
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?
@@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.
Did you need to put a pressure switch on your compressor?
No, I reused the one that was already on the dryer accumulator. 1:47
Curious, did you use a spanner wrench to rotate the clutch?
No I didn't. That is a good idea though. Thanks for watching!
where do you add pag oil if the compressor is a bit low? haven't used my ac is 10 years lol
Just add it to the hole where the AC lines bolt to the compressor.
you could probably add it directly to the yellow line right before it sucks up the freon can
Thinking about buying this kit for my Chevy. Curious how well it's held up now?
About to replace the Compressor. Very noisy now and not cooling like it was. We have the lifetime warranty. Glad we do. Good luck!
@@ForceBuilt@ how long did it last?? The compressor
@@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.
i wish that you wash the radiator for better air flow
Yeah, but I have to change it anyway. I have a small leak I didn't know about. Air flow incoming! Thanks for watching!
@@ForceBuilt
🙏🌹
How much were all the parts total cost? thanks in advance.
$400ish to replace everything except the evaporator.
@@ForceBuilt thanks
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..
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!
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
@ezeduke2328 good deal! Good luck
Just fix my ac on my Chevy silverado 1994 and is ice cold 🧊 good video 👍
That's great! Thanks!
.How much did that job cost you? I got to do the same thing on my 75 Chevrolet K10.
between $400 and $500 after I added the condenser. Thanks
@@ForceBuilt Ty, so you can rent the gauges for vacuum pump from Auto Zone??
@@williamb454 i Think you can. Just give them a call before you go to make sure. Thanks
@@ForceBuilt I checked auto Zone and o Reilly, they both rent them out, 330 deposit thou
@@williamb454 Yeah, I always thought that was crazy but that is in case you keep the tool. Good luck!
How much did it take ?
What?
@@ForceBuilt like freon
@@untearly8212 I think 2 cans.
@@ForceBuilt i put 40 ounces in mine is that too much
As long as you didn’t put all 3 cans of Freon in you are okay it takes 32oz so that’s 2cans an 2.10 out of the third can
I guess Ill have to do that to my 91 GMC standard cab short box as well she loses pressure every year , not that bad for out side temp here in Alberta Canada ,this is my truck it looks a lot like yours. thanks for taking time to show us your work ruclips.net/video/-BDUuHcDqW4/видео.html
That truck is awesome! My roads are rough here. I was gonna do a 2-4 drop but yours looks spot on. How does the 4-6 drop handle rough roads?
@@ForceBuilt I installed helper air bags on the rear ,and just last week got rid of the drum brakes and installed little shop MFG disc brakes on the rear , rear calipers were off an 82 caddy Eldorado , much better braking the soft pedal is gone when breaking sir
@@oldbiker9739 How much was it to convert from drum brakes to disc brakes? How difficult was it to replace the old drum brakes? I have a 1996 Chevrolet Cheyenne C1500 sportside.
@@g1soundwave509 go too little shop manufacturing it was almost $ 700.00 CDN , it wasn't too hard to do just make sure the axle centers are clean and install all three brake lines ,
