Frank, you're either an engineer by trade or a retired cert mechanic. Your repair classes are first class. Communication on instruction is pro level, Thank you buddy and God bless. I'll return with an update.
You're welcome. I love it when I can help people in some way.
Lord help the ones out there with the twin turbo 4matic.. like the one I just did. Intercooler in the way of the belt, charge pipe in front of compressor, front diff below haha man its not fun at all but thank you for this video very professional and intuitive.
You just described the job I'm about to do with mine 😆
Any tips?
@@kbh8181 take note of the belt routing, try not to disturb it too much after you release the tension off the compressor pully.. it's a PITA if you have to remove the intercooler. The charge pipe has to come off and note how the bracket is attached. I pulled the compressor out of the bottom with no issues. It's all just so tight.. I'd say the hardest thing was the valve under the windshield wipers.. the little Allen head bolts are sunk down.. just take your time and make sure they are both tight.
@@kbh8181 after I replaced all components, put a vacuum on and checked for leaks... The system would not take the freon.. I brought it up to a oil change place and had them charge through the high side... Works perfectly now.. there is no low pressure switch to "trick" to turn on the compressor.. the high side does both.
@@dustinhodgkinson6377 That's good to know that the compressor can be extracted from the bottom. That charge pipe had me worried but I saw someone else's video on how easy it comes off. You're right, the expansion valve appears to be the most difficult to get to. With this video, we owe Frank a debt of gratitude. I feel super confident this can be knocked out at minimal cost. Dealer wanted $4,400 to do this.
@@kbh8181 I did everything for around $825 including the refill
Simple, concise walkthrough that really saved me a lot of time, great job! I have a 2016 GL 450 but the steps were exactly the same.
Absolutely amazing video series on the ac system change. I have the exact same vehicle and same issue. Just fyi....I think you may have the part numbers mixed up in the description. I initially ordered the 168379 compressor and noticed I had 3 wires on my connector. I sent it back and got the 198322 and noticed it was completely different on the top where the low side is connected. That rectangular box with the 2 screws in it was not there. I ended up sending it back and getting the 168379 again, which looks exactly like the oem factory compressor that I took out.
I double checked. The 168379 is for compressors that do NOT have the start/stop feature (2 wire) The 198322 is for compressors with the start/stop feature (3-wire) the two do look completely different but the connector itself is the same and the connector from the car will fit both models. But if you use a 2-wire compressor on a 3-wire system, it won't function properly, if at all.
@@Drimplant right. Same thing I see at RockAuto when ordering these. If you look at the original compressor that was taken out though, there are 3 wires going into the connector. This GLE just like mine doesn't have auto stop/start though. At any rate, I'm now returning the 198322 and getting the 168379 once again to put in as the replacement. Unless there's something I'm missing when it comes to the number of wires being counted in the equation? It's all good either way. This series of videos was a complete life save!
same problem here, dont have the start/stop feature but the original compressor has 3 wires, so im assuming that i need to return my 2 wire compressor without the Start/Stop feature for a 3 wire compressor with Start/Stop feature even if i dont have it.
yes@@cristianbalan9187
I have the same year and model. It's a shame these compressors seem to all go out around the same time in this model.
Several things: Your compressor is a variable displacement compressor (no clutch, and a crankcase) so, if the system is empty (flushed of old oil throughout and dried) the entire total volume oil charge can, and should be put in the compressor crankcase (either as you did on the low side port, or thru that hex-head plug next to the low side port. If the system has not been flushed, you don't know how much compressor oil is still in the system in the evaporator, condenser, TXV, and lines, so a full oil charge is over-filling the system. Also, since you replaced the compressor, it is sufficient to say that the compressor failed. meaning that it wore out. The reality is that there are metallic particles distributed throughout the system and suspended in the oil and not flushing the system, which IS a hassle to do, means you have an abrasive fluid (compressor oil and metallic particles) circulating in your system. As you comment, your system is working. Ultimately though the longevity of your system will be reduced and the cooling performance will be compromised because of metallic particles plugging at least some of the condenser tubes and fouling the TXV seat. . . Saving $5,000 is of course "priceless" or $5,000. . . The concept that your 7 year old Mercedes already wore out the A/C compressor is unfortunately indicative of our current state of manufacturing. . . Not to make this a this verses that discussion, but my 1999 and 2006 Toyota Camrys still have freezingly cold A/C and have never had anything (anything!) done to them. . . I'm here because I'm repairing my neighbor's 2008 GL550, and he didn't want to spend $6,000 at a shop to have his compressor replaced. . . I wonder if the shop estimate included flushing the system and replacing the condenser, receiver/dryer, and TXV, all of which cannot be flushed. . . Thank you for taking the time to make these videos. I found your TXV video most helpful. . . Mercedes-Benz is MOST DEFINITELY NOT interested in facilitating DIYers in any way. . . Where the heck is the TXV? . . . I've got an idea (said some MB engineer) lets hide EVERYTHING under plastic covers.
If you look at all the videos in this compressor series, you’ll see that I replaced the TSV, compressor and dryer. The system was cleaned. The new compressor was drained of all oil. Half the oil required was placed in the compressor and the other half in the low pressure port.
$6000 is crazy!!!
Great video!
Thanks
Good video 👍👍👍👍
@@eltiomonkey4082 thanks
Frank, I bought the same compressor you showed in the video, but the compressor came with a 2-wire and the car has a 3-wire connection. It will fit into the harness, but the compressor will not kick on. How can I make it to work or is there something else I should check for.
@@MacleanEke you need to return it and get the three wire.
How did you know your compressor failed? I have a E350 and the AC is barely blowing cold when it is over 100F
Failure of pressures to drop as they should when the compressor kicks on.
Great video, i am about to attempt this tomorrow but was wondering if you had to extract the freon from the system before hand?
You should take it to a shop that has an extraction machine and have it removed there. If you simply open a valve, the refrigerant will be expelled into the atmosphere who’s is both harmful and illegal.
It looks like there’s no clutch on the front of the new compressor I bought a new one and also it looks like there’s no clutch, so is it an internal clutch? And it feels like it’s always engaged when turning by hand is this normal? Thanks!
yes
@@letsrolldiyauto1532 one more question when you replaced everything did you have to do a AC reset on yours? it because my AC button is flashing
No I did not. But I did run an OBD II reader and cleared any codes.
My low side pressure is like 150
..high side same.. Is that compressor?
same answer. Either the expansion valve or the compressor. Cant tell you which one.
@@letsrolldiyauto1532 I went ahead bought the compressor and drier and valve.. Leaning toward the control valve in the compressor is stuck... Imma change it out and vac and fill.
I bought both styles of the fourseason AC compressors and per my mechanic friend, both are not fitting my 2016 GLE350 Base, im really confused now. My car doesnt have the Start/Stop feature but the current AC compressor has 3 wires. The 2 wire compressor doesnt look like its coming with a clutch.
There are two compressors for the GLE350, one is a two wire and the other a three wire. I needed (and you probably do, too) the three wire. I bought it from PartsGeek.com Part Number: 137673-05933605
Brand: Four Seasons
Notes: New Compressor -- With 7SES17C Compressor; New With Clutch.
@@letsrolldiyauto1532 did you install the 2 wire no clutch compressor on your GLE? seem like the 2 wire one doesnt come with clutch. Guess i will have the technician install the 3 wire one even if he believes that wont work.
@@cristianbalan9187 3-wire I bought it from PartsGeek.com Part Number: 137673-05933605
Brand: Four Seasons
Notes: New Compressor -- With 7SES17C Compressor; New With Clutch.
How many miles were your GLE's at? Seems like there's a lot of compressor failures. Mine's at about 113,000 miles and just died so I'll be doing this repair once the parts come in.
Mine was at 104,000. My wife’s GLE was at 76,000. Definitely a manufacturing issue. They shouldn’t fail.
Mine was at 104,000. My wife’s GLE was at 76,000.
@@Drimplant Yeah, seems like it should be a recall scenario to me. Mine is kicking on, then overheating almost immediately and shutting off the compressor.
@@yadayadableh2598 Or a class action.
Hello! Great video! Do you know how much Freon should be used? I have heard that you can cause damage by overfilling so just want to be sure. Thank you.
Check the AC Recharge video I have. Basically, start with an empty system. Read the amount of freon (in weight) on the engine compartment placard. Then, using a scale, weigh the freon can before, then after. The difference will be the weight of freon you've added. Continue until you add the amount required.
I have a question do you have to reprogram the ac compressor
No. Just replace.
i have the same model car and year and my AC is blowing hot air, looks like the clutch is engaging but still hot air. I am about to replace the compressor, dryer and expansion valve myself, but lots of car technicians keep saying that the AC system needs to be flushed to avoid metal shavings contamination into the new AC compressor. Is that true and how is it done? thank you
I did not flush mine. With the dryer and compressor and value being replaced, I just have empty hoses. Could there be some metal shavings? Sure, but if the compressor dies not due to destruction of the physical components, I doubt there would be metal to cause a problem. They would probably be contained in the dryer anyway. But a shop has to warranty their work and it's probably not that much additional work for them to flush. But like I said, I didn't and don't have any issues.
thank you so much for the information , great DYI videos@@letsrolldiyauto1532
Sir, how do you drain the oil out of the compressor? Mine only came out a few drops.
You let it drain for a while and also manually turn the compressor clutch. This will open up other chambers to allow the oil to come out from there. I turned the clutch slowly until I saw additional oil starting to come ouit and then left it in that position to drain for a few minutes. Repeat.
How you doing sir how much would you charge to replace ac compressor on a 2014 mercedes c250 sport? Orlando area
I'm a DIY'er trying to help others with these videos. I do not have a shop or do work for others.
How has the compressor held up for you using an aftermarket one?
It's been great. I used a Four Seasons Compressor. Four Seasons it the largest aftermarket auto HVAC manufacturer. The compressor itself is made in Mexico with other components made in Canada. The stock compressor for Mercedes is made in Japan. So both are manufactured in good manufacturing countries. But it's been around 100 degrees all summer and it's performed flawlessly.
What kind of compressor oil does the compressor take? Is PAG 46 fine?
Yes. PAG 46 I put a link to the Compressor oil above.
