For any other car it would be replace but it's a Camry, those items especially water pump and alternator generally needs replacing at 220k but as long as you replace them with OEM Toyota parts you'll be good for years to come.

Pros: good for years to come

Cons: cheap aftermarket parts fail

Vehicle: Toyota Camry

Mileage: 220000 km

My last OEM Toyota alternator made it to 250K miles. My future non-Toyota ones failed because they were cheap remanufactured ones and later I found a failing harmonic balancer that was putting extra pressure on bearings of the alternator

Pros: long lifespan (OEM Toyota)

Cons: failed (non-Toyota remanufactured)

Vehicle: Toyota

Mileage: 250000 km

Did this years ago in my 5th gen, not because of more Amps, but because for some dumb reason the Alternator for the Celica was $250 reman (back in 2014), but Camry's in the Junk yard with Good OEM Alternators were plentiful. That was after I had 3 reman alternators fail in less than 6 months, 2 being DOA!

Pros: good OEM alternators plentiful

Cons: reman alternators fail

Vehicle: Toyota Celica

Wouldn\u2019t recommend unless you like spending your time on the side of the road or at the dealer. Mine just went back to my local dealer today for its 4th alternator in 32k total miles, 3rd one in the last 6 months. Literally just got the car back 5 days ago for the same issue.

Pros: Fun to drive

Cons: unreliable, frequent alternator issues

Vehicle: Audi

Mileage: 51500 km

Die neueren Generatoren sind heute noch Müll (Haltbarkeit). Musste ich erst in meinem A6 erleben (der zu meinem Glück noch auf Garantie ging). Im RS6 gehen die Dinger auch am laufenden Band flöten.

Cons: schlechte Haltbarkeit, häufige Ausfälle

Vehicle: Audi A6
