Yeah that is true. I normally always quote a belt with the job just to be safe. I have seen lately that some compressor will not warranty a compressor now unless you change the belt, especially if it is a stretch belt, and most require you to flush the system no matter what too. But if the belt is in good condition you are right, you can always walk them off just like you put them on.
had a mechanic do motor mounts because I had a back injury.. he left the damn plug off the back of that AC pump.. Turns out with that disconnected, the clutch will engage however no cold air.. I'm assuming that is some type of pressure switch or valve that stops the flow of freon? I got it connected however it was after I pulled the lines and discharged the system.. The guy said to bring it in and he will do the draw down and 1234yf charge for free.. this is why i have trust issues with 'mechanics'..
I fully understand that. That is one reason I started doing the videos as well to show my customers that I actually change stuff and I try to show me running the vehicles at the end as well. There is a pressure switch both high and low for this.
@ryannegrete9799 can you rotate the compressor then? If those two are good then the only thing I can think of without looking at it is the belt may have been bad.
I understand and I appreciate all the info and time sir! I was driving down the road and heard something squealing really loud and then stopped squealing. The AC got hot a few seconds later. So I will check the compressor itself first and repost so maybe my problem will help others as well.
It is a good idea and many times a compressor is not have a warranty unless you change the condenser or flush the system. Typically I flush the system if I do not change the condenser.
I’m having some AC problems with my 2017 Silverado. AC works great until it gets really hot outside (mid 90s and above), then it starts blowing warm air. Pressure in the lines is good, doesn’t appear to be leaking refrigerant anywhere. I’m wondering if it’s a bad pressure switch. Where are they on these trucks? It looked like one on the back of the compressor? Where’s the other?
@@operationoverhaul I don’t, but I could get one and try it. That said, the condenser was replaced just a few month back and the whole system recharged. I’ve only had the truck a month, so it was the previous owner that did it. The condenser looks brand new though, so I would imagine it’s not the culprit.
@DevinGrindy if it has been replaced I would check the pressure switch. There is one on the compressor and then one on the high pressure line. I believe it is near the condenser on the driver side but I cannot remember. It may also be closer to the compressor.
This should be very similar if not the exact same procedure. Normally the tahoe, silverados, suburbans, yukon and xl, and sierras are all about the same as far as engines. The are a few differences but mostly the same.
Currently having problems with my 14 Silverado ac is cold sometimes then just starts blowing warm/cool air not cold. Pressure is good high and low pressure switch is testing good replaced relay all blend doors are working correctly and no codes you can hear the clutch working but has a very slight rattling noise. But it’s always done this. Any ideas what to test next Thanks
The only info I can find for my 2015 Suburban shows that they use 6.6oz of PAG46 oil. My compressor came pre-filled with 3oz of 1234yf oil and says that if my system requires PAG46, I need to drain the oil and refill it with the PAG46 What the hell in the correct info??? Thanks
I have a 2014 Silverado. I click the link for the ac compressor it shows me a RYC compressor not a Murray like in the video. Are all Murray AC components all owned by O’Rileys auto?
Yeah that would be great. I looked all over the internet. I can not find Murray Climate Control website anywhere. But I do believe O Riley’s owns the trademark for Murray. No other parts store sells that brand.
You are correct. I looked it up and Murray was purchased by Oreilly's Auto. I also discovered that RYC and Four Seasons are sister companies as well. So a RYC and Four Seasons (I think Napa carries them) are the made in the same factory. I could not find a link to a Murray for you. The RYC is the only one I can find. Sorry about that.
No problem. I just wanted to double check some of the part numbers before I purchased and came along all of this. I do know RYC has a website but even putting all my info in. It shows a couple of kits but It doesn’t show the difference. So I have tried calling them and I emailed them waiting on a response. But your video is very helpful. I just like doing a lot of investigating before I purchase. Just so I have all the right stuff here when I go tearing it down.
I wish more people would be like you and research stuff before purchasing. Sometimes more expensive is not always the best option. If you need anything else feel free to contact me. I will help out as much as I can.
It is the same as any other compressor but here is a video of mine I explain how to do it. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-b5DL5OV6Xl0.html go to the 11 minute mark and I explain how to add and subtract the oil in ac compressors.
Sounds like the clutches are bad on them. Can you measure the air gap on the clutches and let me know what they read? It should be between .4 to .7 mm air gap on these.
