Alternator OEM Volvo or GENERAL MOTORS

The V8s are good. I've had 2 pulleys/bearings go bad. The second failed completely, dropping the aux belt and damaging the timing cover. If you hear any weird noises from the engine bay, check your pulleys.

They're also not as bad on fuel as you'd expect. I've regularly seen 25mpg+ on a good run.

ABS modules and siren modules always fail, but are relatively cheap & easy to replace. Alternators also seem to be a weak point and are _really_ awkward to get to.

I will always vote for a 10SI or 12SI GM alternator swap on an L-series engine. Affordable conversion bracket. 1-wire GM alternators are simple, reliable, cheap and readily available online but not easy to find in parts stores. 3 wire GM alternators are are easy enough to wire up and are absolutely everywhere in parts stores if you’re more concerned about parts availability and potential breakdowns on long adventures.

Maintenance I do oil every 10k km including all filters except fuel filter (every 2nd oil change). Basically never burns any oil, didn’t have to fill up at all. Only alternator broke down in extreme heat at 150k km but that’s expected.

The OEM alternator is only 55 amps and costs nearly $400, which is stupid expensive and wholly inadequate for off-road lighting, audio amplifiers, and other additional accessories so I decided to go with the CS130D GM alternator, purchased for under $100 new (no core charge) and has a 130 amp capacity.

I'm getting 14.8v from the upgraded alternator at 700rpm and maintaining 14.2v when every possible accessory and light is turned on at idle.

My shitbox, I replaced my alternator just for my window motor to go bad, I replaced the window motor just for the thermostat to go bad the next day, it’s inevitable.

Next and least expensive, would be to buy a new alternator from Volvo and have them install it. It could be that there is a known issue with the alternator that you put on there if it's not from Volvo.

This was a new genuine Volvo alternator I had Volvo put in, not a cheap or rebuilt part. Also, the battery is only about a year old. Could this really be a failing alternator or could something else be going on?

I got this message when the mechanic replaced my alternator with a non-OEM unit that didn't have a voltage regulator.

three alternators in a Cadillac, even "new GM" are remans, only way to get a new one (never installed, made of new parts, new for you) is to buy a new car.

Had an appetite for alternators, as they put it behind the rear cylinder head and tried to keep it cool with some little rubber/plastic air duct. Failboat. We sold the car with its third alternator, each failure attributed to failure of the rear bearings.
