- how to fix or repair the compressor. This is a 1993 Cadillac Eldorado. Most 4.9L, 4.5L, and 4.1L front wheel drive engines should be about the same job from about 1985-1995 I do believe. Ac compressor is an exact fit for 1994-1999 DeVille, 1993-2002 Eldorado, and 1993-1997 Seville. This is not a Northstar engine!

A pretty good summary of what a mechanic goes through, tricky access, problematic bolts, rust etc. Nice walk through.
The Eldorado air conditioning came out great. Thank you for your help.
I thank you for taking the time and effort to post this excellent tutorial. Your hard work and willingness to share your knowledge is very generous. Thank you a million! I hope my 94 DeVille with the 4.9 goes smoothly and having watched this video twice, I think I can do it!
Welcome
Man i been trying to get those rear bolts off all day.... unsuccessfully...
3 foot extension and swivel socket is what i needed the whole time. Who woulda knew? 😂
Thanks!!!! 🙏
The show goes down at 12 noon today. My friend is going to recover the old R134A in system and put on the new ac compressor and accumulator Orifice tube and seals and recharge it. I will let you know how it all goes. Thank you for your help and guidance
I like this guy...wish he was my neighbor and we could tinker on cars together
Thank you
Thanks!
thank you so much man
90's Cadillacs were so horrible to work on.
Any "east west" engine is horrible to work on lol
I've got a 1990 Eldorado I'm restoring. I need to charge the ac compressor. When I bought the car last week I tuned on the ac and it blew not hot nor cold In between. It is low on R134A previous owner had it converted. It displays Low Refrigerant and the compressor cycled off. Do you know the Color of the Power wire so I can jump it on. Thank you
Unplug the compressor coil. If it has one wire, That will require + power. If it has 2, it will require a +, and -. On a two wire system, it doesn't matter which ones you use, because it is just a pull in winding, making an electromagnet.
Unplug it, and jump with power, and ground. Coil winding can go either way.
@@RustBeltAuto Thank you for your help I greatly appreciate it. I replaced the air conditioning compressor and accumulator along with the Orifice tube and seals. I vacuumed the the system down 3 times and charged the system to the original specification for 90 Eldorado 38.5 R12 8 ounces of mineral oil which I used R134A and Ester. It blows so cold I've got to turn it down. Thanks again
@@stevecarlson6462 went great. Blows ice cold. I replaced the air compressor accumulator and Orifice tube and pulled a vacuum. 38.5 ounces of R134A and 4 ounces of ester oil.
@@stevecarlson6462 Yes it'll be getting hot in Kentucky really soon plus my mom is 73 and I didn't want her riding in the hot car. Their is a guy on Ebay that I buy remanufactured air conditioning compressors from hes really reasonable. 100 for my 90 Eldorado plus 30 for the accularator 4 for the Orifice tube 20 for R134A 9 for ester oil. 200 for labor from a great friend.
I'm doing a 1993 Seville 4.9 right now. GREAT video, thanks so much. Got a new Four Seasons 58963 compressor (supposedly correct fit) and the orientation is off. Its requiring me to twist the lines quite a bit to connect them. No joy so far. Also the old, original compressor used two thin washers and the new one looks like it's meant for a medium and thick washers. Should I keep messing with this to see if I can get the lines on there? Or buy another brand?
It's the wrong compressor. Also, there are separate seals you can buy from Napa, if they do not supply the right ones.
Thanks so much for the response. Exactly....wrong compressor. Ugh. I spoke with Four Seasons and they've confirmed that I need their 58956 even though the 58963 is listed to fit. I hope this helps someone who might be in my situation. Definitely check the orientation when you get a replacement compressor. It should be exactly the same. One more question, Rust, if I may....are there o rings under the switches/sensors that are on the freon line that runs across above the firewall? Or are they crush washers? I would like to change all of the o rings I can while the system is evacuated. Never delt with these. Are they easy? Thanks!
The alternator is right beside the ac compressor.
possible to pull the clutch and pulley off without removing the whole compressor? 94 deville 4.9l my pulley bearing is shot
Yes. There is a puller kit you can buy. Probably have to get it off of Amazon or eBay or something. I don't like replacing just the clutch, because when they get old, their is usually not much life left in the rest of it.
You able to show me a link to a set? I noticed it's the plate between the clutch and pulley that failed.

I lost the center nut that holds the clutch in place, anyone able to find the size specs?
Ah jeez I think I may be in over my head
I need help with my 93 Cadillac a.c fan don’t work I check fuse relays there all good an change the motor control module what can it be
You need a flow chart dude.
Hello I was wondering if you could help me out I need to replace the front passenger motor mount by the air conditioner compressor, I have a 1992 Cadillac sedan DeVille. Do I have to move the compressor out of the way to get at one of the rear nuts on the top of the motor mount?
I have done those a long time ago, but can't remember.
'94 is completely different. Northstar V8
Interesting. That has a 4.9.
How to remove the power Stern pressure line
That's not the Overheatstar is it? Ugh I mean north no overheat no northstar.
No.
I have a 1999 CADILLAC Eldorado
Rust belt auto can you help out please. 1990 Cadillac Eldorado 4.5 Do you have a part number for the color coded manifold seals. How much oil should I put in the new compressor. I'm replacing the Accularator as well will I be safe adding 2 ounces as the gm system calls for 38oz R12 and 8oz oil. It's a R134A system. Thank you
Depends. I would do at least 4 ounces. See if any comes out of the old compressor. If no, go six oz. At least. If yes, add that amount plus 4 more to be safe. It usually depends on how big a leak it is, how it failed, and where, so you need to guess. A slow leak on the cold side will loose less oil. There is a universal o ring kit you can buy at any parts store. It is a pack with a bunch in there.
@@RustBeltAuto The low pressure switch on the low side line failed and leaked all the R134a out. As I manually engaged the compressor I seen it leak and replaced it with new. As I manually engage the compressor it kept popping fuses that is when I discovered the bad clutch so I ordered a remanufactured unit. I believe the coil is touching the plate shorting it out.
Far as the o-ring kit I bought the hr6 GM complete washer seal and o-ring kit
@@Tom-wq2mz They like to melt sometimes.
@@RustBeltAuto brittle from age it was a original part. I'm replacing the Accularator today I'm putting a new low side charge port to insure no leaks. Since the system has been retrofitted to R134A what pag oil do you recommend. Pag-150 ?
So do I add 4oz of oil to the compressor or 8
4oz. For a compressor change. Plus 1 extra for a small leak. 3 extra for a large leak. That sounds like a good guess if it is an 8 oz. System.
Thanks for the feedback, was also wondering if I need to add oil to the new receiver/dryer
It's on a 95 DeVille 4.9l
@@ronnielanderos5984 you can put the oil wherever. It all runs through the system.
@@RustBeltAuto I was referring to adding oil back in to make up for what was in the old accumulator, I took about 1.5 ounces out so I added 1.5 to the new accumulator
Hey man-
