04 corolla - timing belt?

whatlliwear

I've been told theres no need to do a thing as it has a chain and that never needs to be changed... Is this true?

If its a 1.4 VVTi I believe yes its a timing chain (lifetime of engine*)





*Subject to regular changing of oil

Lifetime - in theory.

250 000 km - in fact.

All "ZZ" engines are chain driven, not sure about diesels though, but I can easily check that when VIN is provided.

60k miles or 72 months, whichever is sooner.

pretty sure the Avensis with the same engine (2003-2006) had a 90,000 mile interval back then, maybe they revised it?

I wouldn't chance it anyway, 60,000 would be more sensible.

Yes, they did, but there's an info why 60k it's the frequency usually chosen as well.

If your vehicle is a 1999 model year or newer and is equipped with a timing belt, you should replace it every 90,000 miles or six years, whichever comes first.

For all other Toyota vehicles equipped with a timing belt, we recommend that the timing belt be inspected with the other drive belts at 60,000 miles or four years, whichever comes first, and every 15,000 miles thereafter and replaced as necessary. Because the costs involved with inspecting the timing belt may be similar to those of having it replaced, many customers may find it more cost effective to replace the timing belt at 60,000-mile intervals.

Should the timing belt break while you are driving the vehicle, severe engine damage could result. The higher the speed, the more extensive the damage could be. [...]
