Pully or Pump? 04 CS

[parajed]

Hey Guys,

I am not very intuitive with cars, so please bear with me. I have an '04 cayenne S and I am having quite a bit of squeaking. Initially I thought it was the surpintine belt, but up looking closer, it looks like my top pully/pump has a bad bearing as it is having quite a bit of lateral movement. Does anyone know what this part is? It is the one closest to the top, pretty much right in the middle of the engine, right underneat the air intake.

I also have a coolant leak, Not sure where it is coming from yet, but it will drain about 2 litres from my reservoir and stop leaking, so I am guessing that the leak is coming from somewhere high? It is so tight in there I am having a real hard time locating it.

Thanks

I'm certainly not a mechanic, but a pump/pully noise with a coolant leak sounds like a failing water pump to me. Has the operating temperature of the vehicle changed?

Dennis,

Thanks for the reply, car has been running at 90 the whole time, even with some extended highway use. I have never seen it up over that. Not sure if they are linked or just a coincidence. I put the part # into a OEM supplier and came up with just a $25 pully, but maybe that is just for the cover......lol

It seems once the coolant hits a certain level, it doesn't leak nearly as much, maybe just the weight of the extra fluid pushing it out??

Cheers

Dennis,

You were right, my water pump is FF'd. The pully had about 1 1/2" of movement...........................
