Hi. Thank you for the video. Very good explanation and easy to follow. I watched the other of How to replace the compressor belt. And watched this one after I finished replacing the compressor. My compressor won’t start. I didn’t add oil, but it won’t even engage the clutch. Looks like is not getting power to it, or if there is switch or something that needs to be reset. The old one was engaging, but not compressing. But the new one won’t even try to start.
Thank you very much. My refrigerant jar was almost empty and only put 110 psig in the system. Looks like this wasn’t enough pressure to activate the switch. I used a new jar and was able to get over 120 psig. The compressor started and it’s running like a champ. Thank again. I will subscribe to your channel.
I had a leak on the discharge line that goes from the compressor to the condenser. I when to the dealership to buy it, and they told me it was a common problem. They normally recommend to replace it with the compressor and they always have in stock.
I put a Murray compressor on mine two years ago. It made a whining noise that got louder with the rpm of the motor and it immediately failed within a few days. Took it back to O’riely’s and the replacement did the same thing. Took that one back and they replaced it again and now that one was locked up. All three made the same whining noise. Im not impressed with Murray compressors. This one at least lasted almost two years but the whining noise is too much. I’m going back to an AC Delco. It might cost a couple dollars more but if it runs more quietly, I’m ok with it.
I have a 2014 silverado and the ac compressor runs but doesn't seem to pump the freon around. Pressure on the low side is greater than high side which is odd. And... the cooling fans does not turn on when I turn the ac on inside the cabin. Fans work fine to cool the engine but not turning on for the ac. I unpluged the Pressure sensor and fans kick high speed. Any thoughts?
These Gm compressors have a plug on the case towards the front. 4seasons/Murray says they put 3 ounces in the compressor. I've measured anywhere between 1.5 and 4 ounces of oil in these things. 2014 only gets 3.4 ounces.(total oil charge) I believe 2015 is the same. These compressors self destruct fairly regular. GM knows it, doesn't care. (I install the belts kinda the same way you do.) I made a tool to get to those hoses. Quarter drive socket like yours seems to work best. Best Wishes.
Dang, I was sure fixing a freon issue was as easy as finding a leak, sealing it, and adding freon, but too many other things can be wrong and I need to add oil to compressor because I was told it would leak with freon, and then I need to create a vacuum but don't know how. Sigh.... Guess I am paying somebody to do this. I can do the leak fix but the rest is very touchy for me.
Mine was making a rattling sound and today I heard the belt squealing and shut off AC. How do you know if it's the compressor or the clutch? Can the clutch seize up and stop the belt from moving or is it most likely the compressor? Do you have to replace the drier at the same time? Searching online for the drier and not getting any results. 2015 GMC SIerra All Terrain 5.3 flex. 189K
Sometimes it can be pretty hard to tell, if you are lucky it's just the clutch because that won't contaminate the rest of the system if it goes out, to be safe I would get the compressor replaced as soon as possible with a new not rebuilt compressor.
Nice video. Do you recommend changing the condenser at the same time as the compressor? I know some people say if the compressor froze up you end up with debris in the condenser.
It's hard to say, depends on the type of compressor they used new or rebuilt, aftermarket or oem etc. Now a days it seems like everything is super expensive
Good video. Straight and to the point, I like it. Thanks man
Great video! Thank you very much. The stretch belt was kicking my butt.
I used this video so many times. Thanks Brother ✌️
Good video; thanks for the walk through very helpful.

Yeah your connection to clutch probably isn't pressed in all the way or something like that or your r134 level is too low ?
I added refrigerant, but I need to have it running in order to add more.
Or should I jump the pressure switch?
I wouldn't jump the switch maybe test the clutch to make sure its getting power with a test light.

I agree I'm not real impressed with Murray either
You need to add oil they are shipped dry
thanks man great job.

Yeah its kind of shocking they only require a little over 3 ounces .
Great video. You got my subscribe
to check the oil in the compressor I was told to remove the bolt in the front top

Did you say you put on 200 compressors per year? Come on?
No not a year if I did I misspoke in st. Louis we only see a/c work a few months a year usually. Prob 200 in my career
Did you replace the hard plastic flat seals on the lines that connect to the compressor or did you reuse them
The compressor came with new seals.

If theres to much oil in compressor will it make system not take feon or is it a pressure switch on line ??
It will take freon but it will not cool as well.
@@HooptiesGarage I'm still stumped I flushed the evaporator out re vaped for 30 min and still cant get it to take freon
@@crbrepairmotorcycles6608 won't take any at all or just some ? If it takes some and then stops you prob have a blockage like orifice tube etc.
What happens if you don't suck out the freo? Mine is pretty well drained due to a leak, not sure if I need to worry about it or not.
You don't want to change the compressor without draining the entire system and then putting it in a vacumn .
Nice video. Do you recommend changing the condenser at the same time as the compressor? I know some people say if the compressor froze up you end up with debris in the condenser.
It really depends on if you believe the compressor went bad or the clutch if the clutch went bad it shouldn't put debris inside the system.
@@HooptiesGarage Thanks for the feedback.
Where do you replace the drier filter? Is it at the firewall or on the condensor?
why did you skip putting oil in the compressor in the video??
Because he talked about it for ten minutes
Why do t you use the belt tensioner pully as a temoval of the belt?
It's a stretch belt
Just paid $1000 parts and labor for mine! Do you think it was a fair price? On a 2014 Sierra 5.3

You turned the engine backwards. Would not do that
A Chevy small block doesn't care which way you hand turn it.
