when i bought the car with 111k miles the previous owner had replaced the AOS once. at around 120k miles i replaced it again.

AOS and crappy water pump seem to be "consumables" in these cars.

replace water pump every 50-60k as preventive maintenance (you dont want that failing on you) and dont replace the AOS until it fails, it will give you time to replace it before it does any real damage.

people try to get the most out of each AOS but keep one ready for when the time comes.. because it will come

The only thing that seems to be constant with these cars is how inconstant the life of their parts are.
I bought a spare AOS to take with me last year on a 2500 mile road trip.
I took it with me on (2) 2000 mile road trips this year. I'm at 85000+ miles but I think this winter I'm finally actually going to take my spare and replace the original and keep the original as my spare
I just hope the replacement performs as long as the original. I have read here that sometime these replacement don't last very long

Good luck
