imgur.comWow... just wow. No wonder this marque has the reputation that it does. It is an interesting solution...it's stupid, and it works, but it's still stupid.

I feel like the pump is inside it's own casing, and uses some sort of pumping action like a well spigot.

nope, someone posted it: that cable bolts to the rim of the AC compressor pulley, and then the spinning action of that... I don't even know my head hurts just look up in the thread.

What the... Okay seriously, how does that thing work? O.o

I looked at that site and I STILL cannot fathom how the hell that works. I guess I am thinking of a driven impeller which must spin. Is that not the case here? Like is it some flap that gets swept back and forth by that cable/lever combo? Otherwise how the heck does it spin?

If you look at the second link, there is a photo of it mounted on the car. the water pump sits in front of the AC compressor, and the cable attaches to the AC compressor pulley.

I did, but what confuses me is that it looks like that cable is on the wrong side of the bellcrank and would wind around and bind.

Ac compressor spins and drives the water pump, that wire connects to the compressor wheel

This gives "anyone can design a water pump for a Rolls-Royce, but it takes a true genius to design one for a Chevy" a whole new meaning.

I need context. Got a picture of the block where it mounts?

I wish. That box you see is what it was shipped in.

new old stock ? how much ?

What happens when the compressor siezes

Disengage the clutch and you're golden.

On my Ford, the engine wouldn't start. I tried jumping it, but that didn't work. I replaced the starter, still the same deal. Took off the belt, fired right up!

Read "agitator" as "alligator" and spent about 15 seconds looking for an alligator shaped piece of metal. I am not a smart man.

That makes two of us.

Well, at least a seized water pump won't take out your timing chain/belt, I guess. (?)

No, but it might be interesting trying to explain to someone why a failed air conditioner made your engine overheat.
"Yes, I know the air conditioner cools the cabin, not the engine. The engine still overheated because the aircon failed. No, I'm not trying to make you look like an idiot in front of the apprentice, please put the wrench down."

Had to look on how this works and found it.
Link to picture of the AC compressor mounted to the water pump.
this is probably one of the most bizarre, oddly designed things ive ever seen. who the heck thought this was a good idea, or didnt think that maybe like most cars, the AC should be an afterthought, not integral to the normal functioning of the car?? crazy
Explains a lot about why Maserati and Citroen paired up later on, though.. Clearly a similar interest in idiosyncratic design.
Surely there's some room to modify a water pump that's not insane and replace it.
Surely the need for an emergency backup drive mechanism should have clued in the engineer that something was a bit off.
This is genius. Those Italian engineers knew it would eventually fail, so they included a simple backup system.
Like the guys at British Leyland - they knew the electric mirrors would break in about 7 minutes, so they fitted switches and manual joysticks.
Not that different from Alfa who in the early 80's for their GTV6 would provide a handle you fitted in slot in your door panel to wind down your windows when the electric motors inevitably failed.
Fikst for truth.
Here I was wondering why the pump needed a ground wire. this is like steampunk engineering gone wrong.
And this is why Maserati is known as the designer of the most durable and reliable cars ever built.
In fairness, I have never seen a Maserati break-down anywhere.
That's because it never left it's garage.
