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

I\u2019m 43 and only have had 3 cars in my life only Corollas and Camry. I get a new one around 250k miles. They are great reliable cars that run well with basic maintenance. Only wear and tear items have I ever replaced with the exception of an alternateer on one of my corollas at around 200k miles. As long as I can keep going to 250k I will keep buying them.

Pros: great reliable cars

Vehicle: Toyota Corolla

Mileage: 402336 km

The large frame alternator from a 1997-2001 Camry with the 2.2L(5S) will fit the Celica with minimal modifications. I had to grind the staked washer on the alternator a bit on the pivot side, and unbolt the bottom of the adjuster bracket to let it slightly swing out. Result is a 220A alternator in my 6th Gen to power the upgraded sound system without my lights flickering.

Pros: powers sound system, no flickering

Cons: minimal modifications needed

Vehicle: Toyota Celica

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

I have one with 44k miles sitting in the garage right now with a bad TPS and an oil leak.

The last drive down the street saw me with a dead alternator and blown alternator fuse. Replacing those two resulted in the above surprises afterwards.

Even replacing the alternator is a half day knuckle busting job assuming you know what you are doing.

Cons: bad TPS, oil leak

My alternator in my 2007 V6 RAV4 died just under 2 years ago (Dec 2023), and I got it replaced at a local Toyota dealership. Now, about 20k miles later, I needed a jump start 2 days in a row, and O'Reilly Auto Parts battery tester said the alternator is dead again. Most sources say replacement alternators should last 5-10 years.

Cons: premature failure, short lifespan

Vehicle: Toyota

Mileage: 32187 km
