Default Alternator?
Average life of an alternator in a GX? Replaced the timing belt water pump and thermostat at 100K, at 111K now. Wondering the time left on the alternator. Serpentine belt also changed.

Thx

There is no average life. Some fail at 60k, some fail at 200k. I’m at 167k on my original. If you’re worried about it, change it.

60K is crazy! I'm leaving it now but probably will plan for a Nov 2018 replacement.

Even if Alternator dies, battery will keep the car running quite a bit specially in summer. Sudden failure is rare. Don't worry too much.
