That was great information. Thanks. Yes, the clutch pulley started with the Generation 4, has been used by lots of European manufacturers for years, Mitsubishi since 1999(I think) and supposedly saves wear and tear on the serpentine belt and items driven by the belt.
Prices can be all over the place for alternators depending on warranty, clutch pulley or not AND per your Post a "quality" clutch pulley or not.
When I had my alternator replaced over a year ago (October 2007), the prices for the alternator were:
Sangsters Automotive Supplies (local): $260; two year warranty; no clutch pulley.
Dealership (trade price): $220; one year warranty; no clutch pulley.
Carquest: $320; one year warranty; clutch pulley included.
Sangster's was just up the road from the repair shop (much more convenient) so I used that one and had them use my old clutch pulley.
Funny thing, the Mechanic said "I'm a bit worried, I want to show you what I have done (took me to the vehicle), your alternator has a clutch pulley and it may have been the source of the noise, I'm worried I didn't fix the problem although it sounds like it's fixed. If not, the part will likely have to be purchased from the Dealership. Keep an eye on it and let me know."
The job was a success and all is well to this point in time.
I have been trying to find out, in numerous Posts on here, as to what tool is used to remove / install the clutch pulley. From research on the web, there appears to be a special tool required. Can you enlighten me on that? It would be much appreciated and close out a "cold case" file.
