just wondering
im not having a alternator problem but i saw this mentioned in another thread that GM only used them for like 3 years then they decided they where not so good so they washed up fast in that 3 year period

so wondering
if i ever need to replace the alternator in my 2000 Seville
does it have to be the water cooled or can i just put a regular alternator that has the proper amps and all ?

does anyone know what there purpose to using a water cooled alternator was ?

Unless there is a mounting difference it should function with out coolant. The alternators do all have a fan sucking out heat. Cooling systems integrated into the alternator is nothing new. Other manufactures do this in hi amp duty alternators. They run very hot. If you have a coolant cooled alternator & it is in good shape I would consider it a good thing to have.

I have a '98 STS that has the water cooled alternator and when it went out I had it rebuilt by a local shop for $125 and it's still running with 206,000 miles on the car now.

As LaneB said, I will second that most Alternator/starter shops rebuild them very well and you would surely save a bunch over buyng new. A rebuild at parts stores ups the price. A independent rebuilder specialist eliminates the retailer expense.

i don;'t think we have any shops around here that specialize in starters and alternators and just electrical
they are all mechanics or dealerships
i don't think there is anyone around here that would do it confidently and not try to sell me a new part

I had mine rebuilt when I had the craddle out for the hg job. I believe it was $65 to have it rebuilt. But that's me taking it out and bring it to them. Also I called my local GM dealer to try and get new hoses for mine liquid cooled alternator and they didn't show anything about them having liquid cooled alts. And they were looking the parts up by the vin number. I ended up using trans cooler hose for the lower ones and using the old ones on the top cause they weren't that bad. Luckily the one that needed two bends in it stayed when I twisted it the right way.

When my 00 DHS blew head gaskets at 280000 miles I got an 02 engine, studded it and used its alternator (non liquid cooled). I know the electrical connections from my 00 harness worked fine. Why not go to auto parts store and compare them, I believe they are the same model number and only the voltage regulator is actually water cooled.

Thumper, what do you do for a living?

It is cooled because it runs very hot, this lengthens its service life.

Why it was discintinued?

My guess is to reduce production cost.

Thumper, what do you do for a living?



what ever it is it allows me to pour over 20k including purchase price of a 2000 cadillac seville sls in the last 23 months lol

Lets just say not including the car repairs
but if i ad up all my monthy exspensis would be power water gas 50 dollars if something goes wrong iwth the house got one of those home warrantys on it so pay the 50 deductable per items so about 150 a year for that

monthly car washes and stuff

Im at around 2900-3400 a month depending on whats going on id say winter months i don't keep the heat on much i like it cold so the summer is uusaly when it jumps to 3300-3500 a month
then you add about 600 a month in auto repairs well not every month but they way it comes out in the last 23 months 14k ruffly 550-650 a month if you decided it by 23 months but 14k or right around there all together
so that goes from say an avg of 3100 to 3700 a month

then i got a phone called about 4 years ago
from EDS saying that There was an opening in my old Department GMPD at the time now i believe they jsut changed last year to GMRP if your are a GM dealer and deal with GM credit card rewards im probalby the hard ass that you spoke with on the phone when trying to figure out why the customer could not use all his points depending on what car
but you call in and have them find out from my deparment cause youd rather let them think they can use them all get them hyped about getting a new car and know you have the Customer taged for a car at a price they cant turn down to only find out they have 3000 dolalrs in points they cant use
i was also one of the 3 ppl in the program who could actually approve for all there points to be used if they had a card they couldn't but if you the dealer had been nicer i would have probably done it lol I worked until last year when they laid me off in Feburary i started ack at 30k a year first year with sighing bonus of 15k
the flowing year my contract involved a increase from 30k to 55k stayed there for 2 years the last year i re sighed my Contract for 65 a year plus bonuses it was a 2 year contract then when HP bought out EDS they came to me with an offer to buy my Contract out for the 65a year plus 10 more
i had a 5 years paid on a 25 year morgage at the time paying 3100 for a house in NorthVille Mi owed about zero down for 25 years after interests it was going to be well over a mill but if you know anything about northville Mi you know houses there avg a mill for the small ones

wow i pass there like eveyr other day i hate the trafic during rush hour on 480 so if im on the road i jump at state take brookpark up to 42 then cut across 42 wich is pearl to 82 and then im back on the highway past rush hour cuts about 1 hour of a trip


just what sucks is i have to pay the Mechanic to take it out then take it in to rebuild it then bring it back so im paying for a labor charge but no warranty on the labor unless its mechanics fualt that it would fail
yeah part would be under warranty and they would have no idea how many miles where on it so it wouldnt be stuck with a 12k warranty so that might be good thanks for the help going to call them tomorow just to see what they would charge

The water cooled alternator is a model LR-630. It mounts to the side of the engine with two bolts, one thru the top of the oval shaped flange on the front face of the alternator, the other thru the bottom. It also mounts to the front face of the engine with two bolts that fit in a hole and a slotted arm in the top face of the alternator. I don't think there is another alternator that uses the same style of mounting. A 2000 may be able to use a 2001 thru 2005 alternator but I've never compared them side by side.



Also the 98,99 water cooled alternator uses a different voltage regulator than the 2000 alternator due to the battery thermister on the 98/99 positive battery cable that the 2000 does not have. The 98/99 alternator and the 2000 alternator are not interchangeable. If you put a 2000 alternator in a 98 or 99 it won't charge, and vic versa, and if a 2001 thru 2005 alternator is a direct fit it won't work on a 98/99 because of the thermister at the battery connection.

I'm late to this thread, but if you look in a parts catalog your water cooled alt is only about $50 more than the air cooled model. There's no reason to really bother trying to change it from the original.

That said, my Eldo has the air cooled model on the same engine as your SLS, so at worst you could get mounting brackets off a car with the air cooled and it would bolt up (as others have said).

So when it bolts on to the engine does it bold onto the block or is it the uppder half case area that it bolts onto just curiouse i guess ill go and look
but just wondering if the mechanic had to do anything special to the block to get the alternator to fit since the blockw as from a 2002 hmm

good to know this
well its going strong ad all right now
are there any tall tells to look for when a alt starts going bad or does it just go bad without any sighns just wondering and all

also if the alt stops working does that stop the watter pump ?
i know the other cars i have had has had only one belt on them and all run by the alternators and if the alternator stops working then the pump stops working and then you overheate and blow somehting bad if you don't stop or untill the battery dies
but in the seville i see that are 2 belts wich one goes to the engine for the cooling and the watter pump
will if the alternator feels and over heats will it stop the water pump and then cause the Engin to over heat or will the batter die before that happens ?
