This tool can save you a lot of money working on your automotive air conditioning compressor clutch. Here’s how:

The compressor is making a clink-clink sound that’s even more noticeable when the compressor is disengaged and the pulley is just free wheeling. You can hear it even better with the belt removed and the motor turned off by just spinning the pulley by hand. It should spin easily and it may be obvious that the pulley bearing is worn.

An AC repair shop would like to replace the entire compressor, including the clutch. This will be expensive because between the cost of the new/rebuilt compressor, the labor to remove the old compressor and install the new, and the cost of recharging the system with new refrigerant you would probably pay between $500 and $1000. Additionally, you would likely have to replace the receiver/dryer because the system has now been opened and exposed to the air and humidity. But the only thing causing the noise is a bad pulley bearing, which really ought to be repaired because if it lets go the belt(s) may cause havoc in the engine compartment.

If your clutch plate cover has three holes arranged in a triangular pattern, the tool is used to hold it in place and keep it from turning while you remove the center bolt holding the clutch to the compressor shaft. That center bolt is not torqued down particularly tightly, or is it set with locktite, so it doesn’t come out with a struggle. With the bolt out you can pry the clutch from the compressor. Beware of any spacers and shims falling out as you remove it. Note that you are doing all this while the compressor is still on the car if you can gain access to the front of the clutch/compressor so no gas is lost.

Don't know how all these 5 star reviewers actually used this tool because you cannot fit a socket through the hole in the center. I was able to sort-of use it by drilling two holes out near the big end and using two of the pegs through those holes. If you are going to go to all that trouble might as well just use a piece of scrap metal and a couple of bolts that fit the threads on your clutch.

This A/C clutch holding tool worked fairly well for me. I only give it 4 stars since at least on my compressor (2002 Honda Civic), it was somewhat difficult getting my socket to fit through the middle hole, while also having the 3-prongs close enough together to fit in the holes on my clutch plate. However, the engineers that designed the tool probably did their best to make this a universal tool and to fit as many A/C compressors as possible. Since the tool fulfilled its purpose, I can't complain. The price was awesome and it seemed like a tool of decent quality.

If you have ever want to feel like you have been cursed in life, know this.... try replacing a very inaccessible car air conditioning clutch while its still in the car. If you think that the idea of rectal brain surgery sounds like a fun hobby than you don't even want to look at this tool and enjoy. I recommend making life easier and taking the A/C compressor out of the car, but (for me at least) I'd rather not pull the radiator and recharge the air conditioner refrigerant to remove a $0.50 washer shim.

As near useless as this tool can be, I was so happy I bought it. I previously used bolts to try and hold the clutch plate so i could get the center bolt out and remove some shims to take out the slack in the magnetic clutch and I wanted to make my life easier......AND this tool did - For the price, buy it.

Now, this tool sucks major and this is why. The set screws don't lock at all and so in tight spaces you loose your adjustment... on a bench it might perfect, but in the belly of the beast, it ain't. My fix was a combination of lock washers and finally I just made double sure with super glue (if i need to make a future change I will find a way. Once the screws stopped trying to fill my mind with insanity and blind rage, the tool was useful, but not great.

I wish there was different length posts available because as is there is a large gap between the wrench and clutch plate, which makes it hard to fit a socket in a tight space and also it makes the wrench hard to hold in place. At some point I might weld a nut onto the handle or punch out a socket wrench square so I can use another wrench to hold it steady and clear my hand from the work area for the center bolt wrench.

Again. A/C clutch job. Buy it. Its cheap junk but half the price a brick and mortar store would charge for the same tool.

The tool saves you a whole bunch of time when you need to remove the AC clutch and it's only 6 bucks... what more could you ask for?

Well constructed, when compared to the similar offerings from my local hardware store (which sells it for over $15)

The three points are adjustable. Some older clutch design, for example my wife's mustang does not have holes for the pin to stick in to, but instead I just adjusted the pin to grab on 3 bumps that's sticking out from the outer clutch plate, and it worked well as well.

For 7$ you cant beat it. You use this tool for about 2 seconds, it holds the clutch on the compressor in place so you can loosen the nut, bolt or screw holding it onto the compressor. If you do not have this, the screw/nut/bolt turns freely along with the clutch. Its usually oily and very smooth so its impossible to hold onto tight enough to work. Also, a belt or strap wrench around the pulley wont work because the outer pulley turns freely (so belt on car can turn without turning compressor). This tool has reversible pins with 2 sizes, small and larger to fit in whatever size hole is on the compressor. For the price, it cannot be beat. It does exactly what you need it to do, and maybe there are better ones, I don't know. I do know that for 7$, it does EXACTLY what it is supposed to do, and does it perfectly. I highly recommend it.
