Alternator VALEO or OEM Volvo

Had the same in reverse. Bosch factory, Valeo worked fine though.

Remember the old Bosch and Valeo alternators where the brushes were built into the regulator, which cost $15 and came off the back with two screws? Pepperidge Farm remembers.

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.

Bought a used Valeo alternator, and sure enough, the charging problems went away, and it starts charging as soon as I start the car.

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.

Cheapest for me was a new Valeo unit from Rockauto. Cheaper than Turner too.

I had Valeo in my other car, very common for Bosche to overcharge.

I did see something recently where an aftermarket alternator made by Valeo had the same part number as the Original Toyota part, but in fact had another software part number that made it through an error and not work properly.

Mesmo um Valeo novo está caríssimo, pede mais orçamentos.

Alternator is my wild guess: Valeo alternators have long sucked, kinda like their starter motors.
