I have not heard of that. My 1997 N* alternator does not have any hoses attatched to it. I am sure that if it did, it would have been leaking by now.
If there ever was one, will someone fill me in please.

I am not 100% sure but I think that the water cooled alternator was on the 99 model year only.

Not liquid cooled for Aurora. I believe 98 and 99 were the only years for that spectacular piece of engineering but was on another thread where the OP had a 98 he swore was not liquid cooled. However Rockauto lists 98 Seville alternator as being liquid cooled as well. :hmm: No matter, your Olds is safe. Cadillacs tend to spit out aftermarket alternators so I'd spend the few extra bucks to go OEM if you can. The Aurora probably sucks as bad as Cadillac for replacement labor time and tight maneuvering quarters.

WOW what a job for a alternator. It is not coolent cooled but still a hell of a lot of work. you have to pull the radiator to get it out. my old GMC truck was 2 bolts and a plug.....done.
now my wife has a aurora 4.0 and i have a STS what was i thinking!

I have a '99, and it does have a water-cooled alternator, with a small hose coming from low on the passenger-side radiator tank.

98 and 99 Sevilles have the liquid cooled alternator. Auroras, Eldorados, Devilles never did. I think I've seen the odd 2000/2001 STS have a liquid cooled, I can't remember for sure. Never seen a DTS with it.
