'03 Matrix / Vibe, what usually goes bad?

Hi all,

I'm thinking of purchasing a used '03 Vibe, stick, 2WD, ~100k.

From reading forums, websites, etc it seems like the most common mechanical complaint is the slipping serpentine belt, that's fixed with a Gatorback brand.

I've also heard of a few people having their clutches go out.

1. Other than that, what are some of the more common failures on the '03 Matrix/Vibe?

Since the 1ZZ-FE has a timing chain, and given the mileage, this is the best list I could come up with for inspect/replace, given the mileage. Please feel free to add to the list if you can think of anything else:

- fluids (coolant, oil, gear oil, brake fluid, hydraulic fluid, PS fluid)
- serpentine belt
- belt tensioner (thanks mikered30)
- spark plugs
- thermostat
- water pump
- air filter
- pcv valve
- tires
- battery & alternator (possibly)
- O2 sensor (thanks dasspr)
- MAF sensor (cleaning; thanks dasspr)


- inspect and clean throttle body
- inspect CV boots
- inspect brakes
- check alignment
- check clutch
- inspect CAT (emissions check; thanks dasspr)

Thanks!
