Have replaced this compresors more than twice. It would be a good idea if you take off the heater plug conector and put it back before you install the compressor . Its way more easy to work on that wire lock
Good info to know. I'm going to change out the ac compressor in my 2002 Chevy Silverado. The auto shop wanted to charge me $550 for parts & labor. I said I'll just TH-cam it and do it myself. Thanks for the video.
No problem! Just make sure you get the system purged very well before hand. Recharging can be done at home but I do recommend if you have a local shop that can do it to have them do it, they got the fancy machine that’ll pull vacuum and purge any pollutants that may have been introduced in the swap. Glad it helped!
You can change the low and high fitting without buying new lines. I did it to my 95. Old style like that have a check ball the newer valves have a shrader valve
Now I gotta get mine going before Springtime starts! Thanks for confirming how to do it all! ONE QUESTION: What about pulling a vacuum on the system - isn't that required?
So technically yes it is. It’s the best way to do it because with a new pump it is good to put the system under vacuum to get all the old stuff out and any debris that might be in there. Also when charging it’s better to first put it under vacuum it just helps absorb more refrigerant into the system. Take it to any body shop or somewhere that has one of the fancy AC machines and it’ll do all of that with a few clicks of some buttons. Shouldn’t be too expensive at all to just charge it up and what not, as long as you do are the one who puts the pump on.
this helped so much! I've been running a little USB fan an riding with the windows down but that's not gonna help when August comes🤣 but great video I will be using the video when installing my ac compressor
Good! I’ll also suggest if it’s leaking to spray the high pressure fitting and low pressure fitting. My compressor was leaking and I also had a leak at my high pressure fitting! Good luck, hopefully you’ll get some coke AC.
I agree but tell people they need to rinse the Condenser is properly right if you have a burned out compressor however you’re not gonna find any are 11 around to flush the system with so my point is the dryers and filters and all that should’ve been changed at the same time the compressor was changed the condenser if it didn’t have no leaks I doubt that it would have anything left in it now if it was a burn out I’d be replacing the condenser also which is more likely got a leak in it to
I'm sorry, but this video drives me nuts. While I don't believe it was intentional, there is a lot of wrong or unmentioned info here. 1. When changing out a compressor you should always always always pull the orifice tube from the condenser and flush the condenser with some type of solvent and then compressed air 2.Also always replace your receiver/drier 3. Flush ALL LINES AND EVAPORATOR with some solvent and then compressed air 4. Before ever adding refrigerant to the system ALWAYS vacuum for at least 30 minutes or you risk damage to your new compressor(you can check if it holds pressure while your gauges are hooked up to it and it's under vacuum by watching to see if the needle on the gauges moves back up towards 0) 5. The Schrader valve in both the high and low pressure ports can 100% be swapped out, it's just not the typical Schrader valve that is most common. I have a 1995 K1500 and have repaired or replace just about everything possible on it. But that asidr, the video was well put together and I would definitely come back to learn more when I needed to provided I was confident the information I was being given was solid. I'm not trying to be mean or rude by any means here, just trying to give a newer channel some honest feedback
thanks that worked I thought somebody must have put them in backwards, ha. also I saw once they were out, that u can spin it with ur finger just right and the flange on the bolt actually has a flat cut side where it leaves just enough to clear it..
I subscribed, and hope you post video of the new a/c lines. My compressor is noisy and leaks along the edges of the frame, so I'm just riding it out, and adding a can every 4ish months. I see you've had your channel for years like me. It's tough to get to monetization and to get the watch time hours and subscribers all in one. Good luck.
Thank you I appreciate it! My ac crapped out a while ago again but it’s been winter time so I haven’t bothered to do anything with it yet, now that it’s getting warmer I gotta get on figuring it out lol.
How about putting oil in the system. Did you already put the amount of oil in the new compressor that it should have for the system. Normally for a complete syatem would be 3 to 6 ounces total?
You should yes, I just did the cheap bottle as a method to see if it still leaked. Definitely tho before heavy use vacuum it out and have it charged properly
@@nickconnors8515 and I will tell you that stuff STINKS! and IF you don't wear gloves or I recommend a mask because you will smell that stuff on you and in your nose for a couple days.
Yes you are supposed to, I was reading apparently they ship with 3 OZ of refrigerant oil so I’d suggest getting some more from the auto parts store and they say in total the compressor holds 8 oz
Definitely should flush out the ac system, shops have special machines that’ll pump them out and then when youre ready will properly fill refrigerant and oil levels
Does anyone know what the bolt size is that connects the bracket to the engine? My compressor was going out and apparently it vibrated out the bolt that connects the bracket itself to the engine. I pulled the compressor to install a bypass and saw the bracket was only being held by a stud? and the bottom bolt. The top of the bracket is a good inch or so away from the engine and allows the belt to walk off. I want to fix it, but since I never saw the bolt I have no idea what to replace with. Searching the web hasn't helped.
I was able to tell mine was shot because that’s where all my refrigerant was leaking from, the first one I got also crapped out in a month and in that case the compressor seized up. It depends on what symptoms you’re having.
It did for a while, however I believe I may have messed up the amount of required oil along with possible faulty unit so I had to replace it once after. I double checked the unit and triple checked the oil and has been great ever since. I believe the proper oil amount for these compressors is 8 Oz of compressor oil.
Got it from autozone, remanufactured, do not recommend at all, mine is a month and a half old and it’s already seized up. Get a brand new one from somewhere besides autozone
That is because the installation wasn't done properly, not because it was a reman unit. I put a remanufactured one in my 95 3 years ago and it's still going strong. And I live in Phoenix Arizona!
I might have forgotten to mention it, I know on my truck it requires 8 OZ of oil and that compressor came filled with 3 OZ, so I bought extra and added the missing 5 Oz to make sure it was full
I would suggest taking this video down. I'm about to do mine and if I wasn't mechanically inclined I would just waste alot of time and money due to this video
I like the way you keep it real by not editing out all the little quirky things that go wrong when doing a job like this.
Just part of it lol, sometimes the things that go wrong are funny, thank you btw!!

I would change my condenser as well it’s a 21 year old truck
there is a flat spot on the head of the bolt so you can pull out the long bolts .
You can change the low and high fitting without buying new lines. I did it to my 95. Old style like that have a check ball the newer valves have a shrader valve
Man😂 I done changed the lines any way. I didn’t make a video cuz it was a quick think but this would have been valuable info lol.
On most of them like my 95 you can change out the high side valve but the low side you just change the valve core
Those bolts you struggled with have a shaved off section on the head that if you align with the pulley will come right off.

Would it be easier to take out the snap ring and O ring and such parts before putting the new compressor in place? Looking at doing this for my '94
Yes it probably would, wish I would have thought of that lol.

how is it the "old O ring" on a new compressor?
If you knock the compressor back pry between compressor and bracket the bolts come right out.
thanks that worked I thought somebody must have put them in backwards, ha. also I saw once they were out, that u can spin it with ur finger just right and the flange on the bolt actually has a flat cut side where it leaves just enough to clear it..
What’s that electrical plug with a snap ring on the back of the air compressor called, I need a replacement
I believe that is the high pressure switch.

How about putting oil in the system. Did you already put the amount of oil in the new compressor that it should have for the system. Normally for a complete syatem would be 3 to 6 ounces total?
Yes sir, apparently this system takes 8 ounces total compressor cokes prefilled with 3 so I added the 5 difference.
Hello- unreal edtion, friend- 🙌
There's a flat spot on the bolts bud 👌
lol I found that after a few minutes of messing around.
Did you ad more oil or did you just leave it as is , I believe they come pre charged with 3oz of pag oil
Yes I did, I believe it’s supposed to have 8oz so I just added the difference of 5 to it.
@@nickconnors8515 thanks 👍
Where does those heater core hoses go too I don't have any on my truck trying too figure out where it goes
Should go to some ports on the water pump, then mine loop around to go through the firewall and to the heater core
I thought you had to vacuum out the system before you could charge it up?
You should yes, I just did the cheap bottle as a method to see if it still leaked. Definitely tho before heavy use vacuum it out and have it charged properly
Do you need the high pressure fitting if it is a 2 door Yukon
I am not sure
did you put compressor oil in the A/C pump pac 45 ?
I did oil the compressor, I can’t remember the oil type.
Thank you soooo much !!!!
When I tried removing my AC compressor, it started leaking/hissing air/oil through the back so I tightened it again. Is that normal?
Yes, to remove the compressor you are supposed to go get the system flushed out so you don’t release all the old refrigerant and oil.
@@nickconnors8515 thanks
@@nickconnors8515 you got a part number for that sensor?
@@nickconnors8515 and I will tell you that stuff STINKS! and IF you don't wear gloves or I recommend a mask because you will smell that stuff on you and in your nose for a couple days.
Do u need to add oil before u install the ac compressor or it wouldn’t leak
Yes you are supposed to, I was reading apparently they ship with 3 OZ of refrigerant oil so I’d suggest getting some more from the auto parts store and they say in total the compressor holds 8 oz
Do you know the length and size of the bolts and nuts
I am not entirely sure, it’s been a while lol.
How do u keep ur truck from dying out when the ac is on ?
I’m not sure lol, I’ve never had that problem, just kinda works.
Do I need to drain the ac system
Or can I just disconnect the lines
Definitely should flush out the ac system, shops have special machines that’ll pump them out and then when youre ready will properly fill refrigerant and oil levels

Not entirely sure, my guess is probably 7/16 or possibly 1/2 inch
How can I tell if my compressor is bad ?
I was able to tell mine was shot because that’s where all my refrigerant was leaking from, the first one I got also crapped out in a month and in that case the compressor seized up. It depends on what symptoms you’re having.
Is it still holding up?
It did for a while, however I believe I may have messed up the amount of required oil along with possible faulty unit so I had to replace it once after. I double checked the unit and triple checked the oil and has been great ever since. I believe the proper oil amount for these compressors is 8 Oz of compressor oil.
where did you obtain the new compressor and what is the proper name or model?
Got it from autozone, remanufactured, do not recommend at all, mine is a month and a half old and it’s already seized up. Get a brand new one from somewhere besides autozone

he didn't vacuum it down and no dryer change or filter change
Correct
What about the oil. did I miss it?
I might have forgotten to mention it, I know on my truck it requires 8 OZ of oil and that compressor came filled with 3 OZ, so I bought extra and added the missing 5 Oz to make sure it was full
Where do you add the extra 5 OZ?
Hey what kind of a/c compressor is that? Is it 4 seasons air compressor?
It’s a remanufactured unit from autozone.
Part #57948
did u delete the smog pump on your truck
I’m not sure if it had such equipment. I know all the EGR stuff is gone
How not to do it
I would suggest taking this video down. I'm about to do mine and if I wasn't mechanically inclined I would just waste alot of time and money due to this video
Imposter
We are two different people FYI, your video was very helpful
