I'm sitting in the drive through at Checkers and there's a weird clicking coming from up front. I shake my head go to my buddy's and he's like "dude? wtf?" I have no idea and figure I'll look into it later. Well 45 later we get a call that there's a huge puddle of "something" in his driveway from where I sat for 5 minutes.

Turns out it was antifreeze/coolant. The clicking is worse and the leak is constant. I took a video so hopefully you guys can help me figure out what it might be before I go to the shop and they're like "that's a bad flux capacitor and you need a new motor".

 

A response I got on my gun forum:

I think the clutch on your supercharger pulley is worn out. Sounds the same as a A/C clutch when they wear out. As for the coolant leak, the best thing you can do is get a pressure tester with the correct coolant tan/rad. cap adaptor and pressurize the system. Look for coolant to be leaking and just follow it back to the source. You should be able to source the part online. Try RockAuto Parts Catalog.

 

Looks like the flat springs that hold the friction plate to the SC clutch have let go. It is possible one swug out and nicked the oil cooler hence the coolant leak.

 

Is that something I can fix myself?

 

It's tough to tell not being at the car itself. Doesnt sound good though! I use an automotive stethoscope to narrow down noises. That video sounds like you'd see an obvious culprit.

If indeed your oil cooler is leaking, I just found them for dirt cheap ($15 shipped) on oediscountparts.com

 

Sounds like the SC bearing or the idler pully

 

Turn the car off and inspect the pulley. You should be able to tell if it's become a lawn edger.

 

Holy ****. I'll look tomorrow.

Any idea what it's going to cost if it's the bearing/clutch?

 

Well the dealership was useless. They had no idea what i was talking about. Can anyone link me to the bearing and clutch? The service manager's best guess was a $1700 assembly.

Also, it is not a lawn edger lol.

 

To test for the click see if you can rotate the rear part of the pulley, that's the clutch plate back and forth.

 

Posting from phone. The part behind the clicking part I assume is the pulley and it did not make any noise when turned.

 

Video is private.

 

needswings.com sells the bearing which I think is about 60.00, you will need to press out the old one from the pulley and press the new one in.

If it is indeed the pressure plate on the pully then you need a new pully at which point you can consider a new oem one (check MB as they typically have lower part costs) or move into a pully from some of the tuners, I think they are in the range of about 700.00.

If the clutch is going then you need to replace the nose section of the SC...big $$$ but you might find a rebuilt SC for less than 3k

 

Thanks. I'll fix the video when i get home. Ugh...this sucks

 

And it should be good now. Let me know your thoughts

 

Looks like you might need a new pulley. It appears the springs are fatigued, and aren't holding the pulley away from the clutch.

The pulley is the part in contact with the belt and also the part you were moving. Behind the moving part is the supercharger magnet. The magnet engages and draws the pulley to it.

 

Pulley would be a good time to upgrade to a performance part? Will it come with a new magnet?

 

The large black magnet is part of the supercharger, and I doubt you need a new one. If you're going to upgrade the pulley, make sure you do your homework and don't run lean. I don't think anyone's had lean issues with a 65mm pulley. If you go smaller (more fun), make sure you confirm the air/fuel before beating on it.

 

So the part that has the belt is the "pulley" the black part i was tapping against is the "magnet" and the thing I was moving was the also the "pulley"?

 

The part that moved is also the pulley. The heavy part that turns by hand is the magnet.
