I would take the serpentine belt off and feel the pulley for play. I'm not sure if there is any openings in the alternator, but maybe something fell into it , like piece of broken belt ?

this procedure stated by your $tealer necessitating engine drop for the V8 alternator is suspicious. Hmmmmmm....:-k

I also spoke to a friend who works as a service technician at a VW dealer on the Mainland and he said that the warranty procedure says to remove the engine. He read it to me word for word. Perhaps they say this to charge more to the warranty company (or VWoA)

I'm not saying it can't be done but it's definately not a DIY job for your average joe.

And furthermore, I'm not paying a dime for the repair so it doesn't really matter to me if they remove the motor or not.

Just had my alternator replaced. I am a major DIY'er (see my write-up on replacing the timing belt), but had my buddy do this at his M-B, Audi, VW, BMW shop. He did NOT remove the engine for the job.

Napa has a replacement alternator they get from Bosch directly that is not water-cooled. It is easier to put back in. Good luck finding a cheaper replacement otherwise. The only other options I found were the 1st VW-type dealer direct suppliers and they were well over $500 plus over $100 core charge. The Bosch replacement is not much cheaper.

How did you deal with the existing water lines in and out of the original alternator?

Is the non water-cooled Napa alternator also 190A just like the water-cooled original one?

 

[MarkLWarner]

Jaxander - we fabbed up a simple bypass tube, insulated it, and mounted it out of the way.

VWdude - yes, it is 190 amps just like the water cooled original.

Thanks for replying.

I was in one of my curious moods and decided to do some reading on the advantages of liquid cooled alternators for automotive applications. Three points caught my attention, although I only came across this from one UK source thus far.

• Faster warm-up of a cold engine to the operating temperature • Additional heating of passenger compartment • Lowering the temperature in the engine compartment

From what I understand, and did not know before I stumbled on this, is that it uses the heat produced from the alternator to help ensure quicker warm up times. Wondering now if this is an emissions thing, or actual difference one would feel in a cold climate like ours?

Mark:

Thanks for the reply. It looks like you nicely thought through the conversion process. I can't wait to hear about the reaction from the first VW tech that sees what you have done.

Decided to take a look today and see if it was possible to DIY. 2 hours later alternator is out. I'm taking it to the rebuild shop on Monday. Contrary to what I thought it's not liquid cooled. Removed wheel, disconnect battery, remove wheel liner, plastic plate underneath, passenger side air box to remove. I'll be doing a DIY when I reassemble. It amazes me that a person such as myself with limited mechanical ability can do this job in 4 hours when the dealership charges 14 hrs. WTF!

Don't forget they have to pay or their lift.

Alternator spins freely, no slop but it does make a noise at one point in the 360 degree rotation when turning by hand.I assume this is amplified when rotating at full speed and tension is applied to the pulley. Found out that the Napa air cooled version is for west coast only. They had no option for me here on the East coast. The unit has a Delphi manufacturer label on it. The part number printed on it is 07C-903-021K. Isn't Delphi was owned by GM?

 

[LocoLobo]

Yes..I don't know if they still are, but at one point Delphi was owned by GM.

Excellent job man! Suddenly I again feel good about my V8 engine being friendlier than meets the eye, thanks to guys like you.

I'm slightly confused concerning the liquid cooled part of things since you observed that yours is not. The self study literature on the AXQ V8 engine writes that the alternator is a 190A liquid cooled part, so now I'm :confused2:. Can someone help clear this discrepancy up?

 

[hendershot]

Thanks for diving in and finding a way-- gives me hope that I can do it when my time comes. I look forward to your DIY.

Here is an AXQ V8 and I don't see any hose fittings for water lines on the alternator part #8

 

[V10]

I guess there was a production change at some point so someone will have to look when the water cooled alt production started. Here is a link to a thread of a guy selling a water cooled unit showing part #:

VWVortex.com - Brand New ALTERNATOR Touareg V8

There is also a VW TSB for coolant leak repair of such with new style o-rings - that TSB would likely show the year and VIN range...

BTW, the illustration I posted above is for a 2004 AXQ V8

 

[V10]

Strange that the part # you listed 07C-903-021K is the same part # listed in the link to the guy selling one which is clearly ported for liquid cooling...?

 

[Perry01]

You know V10, the alternator from the VWVortex site shows the hose fittings coming from the back of the alternator and there is no view of the back of the alternator in the illustration I posted. Maybe they are the same?

There is no part # on the one I posted. Here is the link:

Scroll down and there doesn't seem to be a part # for the alternator.
