Alternator Bosch or OEM Volvo

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.

Check alternator voltage should be above 14V at 1500 RPM. Bosch alternators are crap anymore, I bought a new WAI global alternator, it has strong output so far. Only time will tell if it holds up.

I installed a Bosch re-manufactured unit. Under $200. It has a 24 month warranty and roadside assistance included.

Aftermarket units from Bosch and other are about $300.

The most expensive one at Rock is a Bosch for $186.79+ core.

Mine went out at like 105k swapped out a Bosch immediately but if not always go with denso.

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.

Bought a new bosch alternator and installed it.

Everything went well, or so we thought, as he turned on the car it started to slowly smoke. I assume that the ac compressor plug got shorted or was loosely plug bc it was the hardest thing to replug and the fact the ac isn’t blowing cold air anymore. We recharged the battery to 12.4-12.5 v. The alternator was only pulling 13.3-13.7 v with load and without load. Mind you this was a new OES Bosch alternator.

supplier willing to give me a Bosch remanufactured alternator (as good faith) to compare. after installation on Bosch, the result is worse than the Denso (output at alternator at 12.5V)
