    I believe that all Magnums use a Denso 10S17C A/C Compressor (but I'd check your year/trim level). I rebuilt my AC system last year and bought that whole Compressor.

    Anyway, you can use that model number or "10S series" to look up videos on removal and replacement. Century Bob has great ones like this:


    I did completely rebuild a couple Sanden compressors and basically the clutch and plate comes off after a nut, and a snap ring are removed. The Denso seems similar as described in this instruction manual:

    DMC-81,

    Thank you for that link - while I don't have a Magnum, I think it's going to be very helpful if I have to replace the AC clutch on my 300. Doesn't seem as scary as I thought it would be!

    You are welcome! Glad it is helpful.

    Yes, the A/C compressor is not that hard once you familiarize yourself with it. After learning on my DeLorean restoration, I decided to refresh the Magnum's A/C system after my compressor failed last summer. Since it wasn't a rare unit that had important date codes stamped on it, I just bought a new compressor, instead of rebuilding my old one, especially after 100,000 miles and 11 years of service. The aftermarket units were not that much cheaper than the original OEM Denso part on Amazon, so I went with it. After changing that, a new Denso expansion valve, drier, new O-ring kit and a carefully measured charge, the A/C in the Magnum works better than it ever has. I think it was not charged properly from the factory ( I'm the original owner of the car). Anyway, now I need to turn the A/C down as it gets too cold.

    All 05'-08' engines use the same compressor assembly:

    55111418AB 1 C, D, E, F 48, 49 EG0 2 CLUTCH OVERHAUL KIT, A/C Compressor

    there are differences with the pulley / hub kit that you will need to address with your VIN at the Parts Counter.

    Does anyone happen to have a source for the clutch kit? RockAuto is out of stock and my Google-fu seems to be lacking looking for the kit.

    I've used them in the past, but lately have been getting parts from Tasca. Either way, they both have the coil, but hub assembly and clutch kit are discontinued. Guess I'm looking at a new compressor or heading to a local pull a part. Thanks!

    I'm in the middle of doing that right now. Replacing the clutch/coil/pulley I removed from a wrecking yard. Not that easy while the compressor is still on the car. I don't want to lose the freon. I'm still fighting to put the spring clip back on the coil part. Magnum with 6.1 in it. I jacked up the car, removed the driver front tire, fans, air box, buggied the hoses out of the way and still a f...ing bitch to get at. I'm determined to get it back on....

    Well after turning,twisting just about every way possible, the only way I could get the clip/snap ring for the coil back in was move the steering pump out of the way. From under the car there was no way I could get the clip on because of the position of the compressor and no room to maneuver. With the pump moved, I was able to assembly the complete clutch/coil/hub with the compressor nose pointing up the best it would. After all said and done, it's a bitch to do but do-able. Now I have air cond. again.....yeah

    I just did this two weeks ago, the snap ring has a bevel on one side, maybe you had it facing the wrong way, were you using snap ring pliers? I didn’t have much trouble.

    Oh believe me I know about the bevel. I used the orig. snap ring that was still good (no rust). I have a core v8 compressor that I used to make sure all the parts would fit without any problem before I put it on the compressor. A trial run I would say...

    Send voltage straight to it and see if it engages.
