AC LS Swap C10 Part 2 + Brake Master Upgrade, Console & Tires 

jeremy hunt haha it is addicting. I use to play with LT1s a lot before LSs became affordable. Those are what I started swapping first. Congrats and good luck on the 6.0 build!

The Beige Wonder Thanks man! I'm pretty excited to have a good cup holder finally and that power inverter will be handy.

***** Thanks Harry!

+Guillermo Simental Awesome! Thanks man! Glad to hear it. Good luck! See you at LS Fest next year.

ChevyShawn I may do that! Thanks for the heads upF! I didnt realize that it was coming up already.

No problem. I'm gonna try to have the spare parts truck ready to drive out there. Maybe we will see you there.

+godcarsmoney so is he using just the reservoir from the s10 or the whole master cylinder?

+smilinjoe23 I'm using just the reservoir from the s10 because its lower profile.

+smilinjoe23 Master cylinder came from a full size truck, around 2001.

+AGearHead4Life so the 1988-2000 mc from full-size truck won't work?I misunderstood it and grab one from that model year.

+smilinjoe23 I doubt it'd work. It was a 2000's rounded S10. I dont know the year. I went by the look of it.

Wanderin' Moose Hey John! Thanks man! I often wish I added more detail. Hopefully I include enough of it for most.

***** Yessssir! Too hot and humid here in Alabama! Well, I have been driving without AC for ~11 years now. The reason for AC now is that the last time I took my daughter to catch the Hot Rod Power Tour, she got sick from the heat. That pushed me to get the AC installed before she rides along with me this year on the Power Tour. I hope all has been well for you Jafromobile!

Derrick Wilson Thank you Derrick!

Jorge Almaguer Thank you Jorge! I know how project funds can get tight and affect progress, for sure! That problem is what got me started on RU-vid and my whole channel is based off of. Buck stretching, low budget building! Good luck on you '73 C10 man. I hope you can get back to wrench'n on it again soon.

AGearhead4Life Thanks man, it's good to see you take the time to read comments;) And I sure will get back to work in my truck as soon as I get some money. I got the engine and transmision working nice and smooth, I'm thinking on focusing on the suspension now, but only time will decide that. (I might put some airbags on that badass truck)

Jorge Almaguer Yea buddy! I read and respond to every post on my videos, always have. But as the channel grows its getting harder and harder to keep up with it. I've also got a full time job and 3 kids that require most of my time.Glad to year you've got it running smooth. Thats a good comfortable feeling. Yea, suspension is an important one for the appearance of the ride. I want to bag a truck some day, but it wont be my current truck. I want this truck as dependable as possible and a static drop is more dependable.

Cool! Thanks for sharing. Good info. I'll have to check them out.

ah yea! Just check them out and left a couple comments. Good stuff. I think I like their idea and how their mounts work. Not only does it allow you to easily fit the compressor, but you can also keep the truck oil pan. Good stuff. It looks like you'd have to make a custom driveshaft, but it'd be worth it.

Yep. Only had to notch my motor mount clam shell to clear the square piece that sticks out on the block

Very nice! Thanks again for sharing. I'll pass on the info.

+Domingo Perez The master cylinder is from a full size truck. The reservoir is from a S10. Both came out of the junk yard.

10-4 ok I will have to go and check that out this weekend thanks again bro.

+d Ramirez Thank you Ramirez! I appreciate your support!

I used the factory C10 controls, but need to redo it to allow the PCM to control the AC so that it shuts it off at WOT.

Yessssir! I'll put it on the list. You'd be surprised how easy it is.

@AGearHead4Life did you ever get around to making this video? I'd like to know how you wired it also. There are 2 plugs on the truck compressors, I think the green one is a power signal, and the black one a ground. Also, does any wires from the pcm get integrated into the plugs? Thanks.

BADAZZ93STANG Thank you BADAZZ93STANG!

txchevyrida that's progress! Could you plug it into the climate controls? That should be where it goes, I believe.

Short answer is yes, it'd work fine. Long answer is the only binefit of the LS1 heads is the 2" intake vavle. Those heads flow the same as 5.3 heads though. That is why I like to keep 5.3 heads and put the 2" valve in them. That give a great compression ratio.

Pat Maki You could just use one valve. I didn’t notice my old C10 setup to Gabe a high pressure switch, so I didn’t install a port for one. I regret that! I am now about to open the system to add the high pressure switch and to use a R134 condensor from a newer truck.

@@AGearHead4Life how did you do that? Any videos?

Robbie Niavez This old video of mine should help answer most of those questions. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-jDQbIBQoQ3k.html

Robbie Niavez Wiring info can be found on LT1swapDOTcom. But this video and the video description can give you more ideas. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-VogkaVNGkCU.html

celso guajardo villarreal Gracias Celso!

Doby Gillard No, but I have been strongly considering how I could add one to the system.

I have a stock set up I am experimenting. With I have no accumulator. In line . I also do not have a thdrmostatic on off for my fans. Its manual. Caused the last compressoer to burn the clutch up. I'm just saying. Ben following you for a while. Most of your info is the best out there. Keep on keep in on man! I admire your diligents .

Doby Gillard Thank you Doby! That is a huge complement. wow. And thanks for the continued support! Thanks for the heads up. I was wondering what will happen from too high pressure on the high side. I learned part of it the other night the hard way. I had no fan becuase they were dependent on the PCM to turn them on once the engine reached operating temp. Well the engine cooled enough, so the fan shut off and the pressure climbed extremely high on the high side from the heat in the condenser. The next thing I knew there was a loud pop and the system seemed to have purged the pressure until I cut it off. I didn't locate the relief valve yet, but that's what seemed to have happen because its working fine now. Now that I have the fan to kick on with the AC its been fine, but it would be nice to have the clutch kick out by a high side pressure switch in case that fan failed for some reason. So I'm still working on that. Any idea if the old C10 system had a high side pressure switch?

Not that I am aware of. I am searching for a 1/4''SAE female flare fitting w/valve depressor. like would fit on a R12 service fitting. Two wire cut out at about 395 and back in at 225. Binary switch. I found a 1/4'' male and ordered it then found out it needs to be the female... live and learn... always the hard way for me... Time is getting tougher to come by. as you can tell by my april 12th reply...

Doby Gillard I definitely here you on the value of time. Its gotten so rare lately that it scares me. So far my AC seems to doing well and dependable. Fans are wired to come on with the AC now and its stays blowing about 50*. Temp around here during testing has only been 82* on average though, but very humid.

+KAnthonyStrick1992 Compressor isn't wired into the electric fan. Most AC systems are pretty much self controlled. They have two switches that control it, a high pressure switch and a low pressure switch. My truck only supplies that power that turns it on when I flip the AC switch on my dash, like a light switch. Once the AC system has power it's on. The AC clutch may cycle, but that is hailed on it's own by the pressure switches.

+AGearhead4Life okay I get you. I was thinking that nd just got jumbled when you showed the relays. sorry. lol. was your truck factory a/c? and Im reading a lot you have to wire the compressor into the pcm. Did you by pass that? and if so, how?

+KAnthonyStrick1992 Yes, my truck was factory AC. I just ran the original AC compressor wire to the new compressor. I did not run it to the PCM yet. Giving a signal to the PCM will allow it to idle up when the AC is on to help it idle better. Also, the AC can interrupt power to the compressor when you floor it. For now, I just turn off the AC when I floor it.

+AGearhead4Life Okay thank you. I was racking my brain all last night when I was thinking how to wire this. Thanks for the information.

+KAnthonyStrick1992 No problem. Good luck!

yes, it's in there. I used the controls on the truck to control the compressor though. At least for now.

83-86

anthony jackson Man, I lucked out and my buddy Greg hooked me up with it. It's 3" square tubing and about 30" long.

anthony jackson You're talking about the upper radiator support from my latest video right? Not this video.

godcarsmoney The cluctch engaugement signal does usually go through the PCM, that way the PCM knows to idle the engine up too. I believe this type of compressor just switched on/off and the fancy new style was variable, around 2009?. I do wish that I had installed some type of high pressure switch on this system. I may have to go back and add that.

Doing my research you can only use a 2000 compressor because it cuts on and off with a clutch... I call one of the junk yards in my local area and I noticed it was two different kinds what year truck your compressor came off of.... I'm pretty sure its 99/2000

Deiphi? Might be the one that doesn't need to run through the ECM

godcarsmoney You know, I thought it was a 2001, but it could be older. I just knew that I was looking for one that didnt have the sensor coming out of the rear of it to give more clearance. I can get a part number on it. I do believe that it was a Delphi.

godcarsmoney I think that the 2001 schematics showed it run through the PCM but only as a clutch on/off.

anthony jackson Hey Anthony! I'm not running an engine oil cooler, but I do have a large trans cooler. I dont know the brand of it since I acuired it used. I just looks like a large one that you'd get at a local parts store or a U-Hual.

Braulio Ortiz Maybe something in the suspension? like a ball joint. I'd inspect the suspension and see if you can find any play.

+David Bush There was one plug with two terminals that was on the firewall that went to the old compressor. I used the same wire that went to the old compress to go to the swapped one. If I remember correctly, it didn't matter which of the two to use, because they were both hot when the AC was on. I think the other went to a solenoid on the throttle to idea it up for the AC.

AGearHead4Life my compressor on my 5.3l out of an 01 Tahoe has two two wire plugs on it. One in front, and one in back. Which one do I supply 12v+ to turn on the compressor?

+David Bush The one in the front, near the AC clutch. The AC clutch has an electromagnetic switch to engage the clutch. The other, on the rear, is likely a high pressure switch.

Talking about up under the motor mount? Yes, I bend them up closer to the frame, but I think that was mainly so that I could cut on the mount that I had made more.

txchevyrida Sorry man, I'm color blind. I just chase or test them all to find out what they are. Are they connected to the low pressure switch?

cleenrob Yep, I used the factory C10 drier, evap and condenser.

Rico Turk No, I havent made a video on the fuel system but I guess that would be a good idea. I ahve a '87 truck. So it was alreadi TBI fuel injected. So it had the intank pump already. All I did was swap in a higher pressure fuel pump. Then at the end that connected to the TBI unit, I cut the hard line and used high pressure hose and doubled high pressure hose clamps. If you get on my Facebook blog page from a desktop, go into the photo album of the truck and you see pics of what I did there.

Chuck Norris I got it from LMCtruckDOTcom.

Hernan Leal I cant remember at this moment, but I would expect that I either got it from LMCTruck”DOT”com or possibly RockAuto”DOT”com.

AGearHead4Life thanks. I didn’t check lmc but rockauto only had the one I was talking about. I ordered it anyway. I’ll see if I can plug it somehow

jeremy hunt Not usually, the yoke will stick out an inch further. You may be able to find a way around that though. I had to use the central mounting ones because my 80e yoke that I had had an inch thicker head on it.

I've seen some ls swaps in place of the caprice lt1's, use they're stock 4l60e trans.. so I may be on to something. .

Byron Callic I used the stock 2001 truck 5.3 AC belt. Its on a separate grove on the crank and power spins the AC. Gates # K040378

thanks man

Byron Callic The yoke would work, but probalby the yoke that you have would work too, if you have a th350. If you do have a th350, your driveshaft will be too long and I dont think the one off of the 2002 would be the right length. I've alwasy wanted to use a newer driveshaft and have it cut to fit our trucks. Theyre aluminum and the light weigth would be good for rotating mass, but theyre not as strong and with added power have been known to explode.

thank you

Byron Callic No problem. Oh, I also meant to tell you that you could get a driveshaft from a long wheel base C10 that had a 700r4 trans and it'd fit. You'll need to either use "one inch set-back" swap plates or Dirty Dingo adjustable swap plates.

anthony jackson They may be on back order. That seems to happen often. You can find them on alpermotorsportsDOTcom website too.

+Big Rone Well I wouldnt say that it was easy, but to me it was worth it. I love these seats. I made a video that gives you an idea of how to make them fit. Here's the link: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-a6HsY41BiZI.html

I do not remember at this time, but I bet that it was around two cans.

No, it's the original.

Did you use original push tube from your old master cylinder or did u use the push tube from new master cylinder??

nandoGdog Possibly but I don’t know for sure. You could also change out the booster. Better yet, convert to hydroboost. I’ll be converting to hydroboost soon.

txchevyrida GM truck and suburbans around 2000 and up. the 6.0s arent near as common as the 5.3s though. Thats why the 6.0s cost twice as much as a 5.3. 5.3s are everywhere and can be picked up complete with all accessories, harness and all ready to run with about 150k miles for around $700 on average.

I bought a new one from a local parts store for two reasons. Mainly for the warranty and I bought new instead of the cheaper reman version, because I've seen way too many reman compressors warranty returned when I sold parts for four years. It could have been installer error, but I didn't want to take a chance.

If you wanted the cheapest but good, I'd bet that rockautoDOTcom would have the best price.

+AGearHead4Life Yeah sounds about right i was gonna order one but i was also thinking about warranty issues if the issue comes around... Hows the a/c been performing I know those ls style a/c compressors last a while...

I don't know much about the life of the LS compressors, but I've read something about a "deslugger" kit for them. To help them start up slower to keep from trying to compress the liquid refrigerant since the compressor is down at the bottom of the system. IDK just something I read. Anyway, it's been working great man. I'm loving it. Stays blowing around 50* in the cab. Of course I want to improve it as much as possible, like any gearhead. So I want to put the foam in between the condenser and radiator to help air flow. Im also not currently using the high speed function on my fan, because I need a larger relay/fuse setup. Finally I'l like to add a fan to the condenser to help it even more at idle. These are all not necessary things, just me trying to make it the best it can be. I want it to sit in a parking lot for hours in 105* heat outside and have no issue staying cool inside. lol

+AGearHead4Life I understand I bet when you get the cooling fans wired on high that gonna be just what your looking for... what did you electric fans come off of?

anthony jackson For the EGR port on the intake?

Motor mount

7s in the front and 8s in the rear.

David Santillan The hard line that I had to replace, from the condensor to the evap high side? I got it from LMCtruckDOTcom.

David Santillan At 4:00 in this video it shows and explains what I did for the fan to come on with the AC.

AGearhead4Life so it's from the pressure switch to the relay but what plug on the relay?

David Santillan A relay will have a trigger side of it, that wire will be what triggers the relay. Are you following my Facebook blog page or our group FB page? If so, I can share a diagram that I have on there of how a relay works. It's also a diagram of how to wire in a radiator fan relay.

AGearhead4Life well I wired it directly to the fans and that made my whole system shut off and will only come on when the fans come on when the temp is at its point but I cut off the wires I point that I hooked on the fans and still no power to the ac system

David Santillan Yea, that power wire coming from the trucks AC harness cant supply enough power to run the fans. That's why it is used to control a relay. All a relay is basically a switch. It allows a small amout of amerage to trigger a switch to allow a large about a amperage to pass. So you'd use that wire from the AC harness to trigger the realy to allow power through the thicker power cable to the fans. It is difficult to explain in words, but is very simple. That is why I offered to show you the diagram. Its way more simple then it sounds. You probably blew a fuse trying to run the fans on that wire. Check your fuses.

victor chavelas Victor, I'm not sure how to take your comment. You know a lot of people leave sarcastic rude comments and when they do, they use all caps and lots of punctuation like you have. I can easily misunderstand your comment as sarcasm and not respond to it, but I'm thinking that in this case this might actually be a serious question. If so, all you have to do is type it normally.

SORRY BRO THATS HOW I TYPE .. BUT MY IS QUESTION IS SERIOUS HOW CAN I INSTALL N A RELAY I GOT A 82 CAMARO Z28 I SWAP THE MOTOR THIS YEAR TO A 5.7 VORTEC IN I TOOK THE FAN CLUTCH OFF N IN PUT TWO ELECTRICAL FAN N A ELECTRICAL FUEL PUMP THE PROBLEM IS I GOT TO SWITCH ONE THE FUEL IN ONE FOR THE TWO FAN BE THAT SWITCH BLOWING UP TWICE A MONTH SO WAT CAN I DO..........

Ah, ok. Are you on Facebook? On my FB blog page, I have a picture of how to set up a relay for a fan. It seems to help simplify the process a lot. When you go to my blog page "AGearHead4Life" on FB, you can find the picture in the photo album named "LSx Swap Parts and Related".

You may not need an account to view the page either.
