Hullo peeps.

g/f has a 1 litre Yaris on a 51 plate.

Service book suggests timing belt needs changing at 60,000 miles (£450 - £550 = Yikes!!).

Lady on the phone reckons it should have a timing chain and so it does not require changing.

My question is, what would make a manufacturer use a chain rather than belt (apart from that it would be more durable). Without having any reason to back it up, I assumed that a chain would be used on cars with bigger engines and did not expect the one litre Yaris to have one (like I say, I have no reason for thinking this, just my niaivity).

Does anyone know if the Yaris has a chain rather than a belt or how I might find out???

Thanks guys.

Toyota Main Dealer will have the details - give them a call or ask on the Yaris Forums.

Chains are a bit more expensive, so just the quality cars have them. I'm impressed the Yaris has one, but not that surprised as they have a good reputation for quality.

You would have thought, but when I got the quote for the change from one main dealer (I asked for timing belt change as that is what the service book suggested was required) I didn't like it so rang another.

The other one said they thought it had a chain which didn't need changing. She then said she would check with someone more technical and would call me back. Just wanted to find out from someone else before I made the decision.

My wifes old 1.0 micra used to have a chain not a belt, so probably not that unusual on jap cars

It was white too.... actually is wasn't a bad little thing, dead light and quite revvy so you could catch quite a few cars by surprise!

Timing belt cam drives are cheaper to design and build and of course easier to change than a timing chain.

A timing chain is a more mechanically efficient way to drive the camshafts and because the chain runs in oil and is in a pretty clean environment it will last for the life of the engine and is far more reliable after a biggish mileage. I would much prefer a timing chain to a belt any time.

Yep, my Saab has a chain, I hate the mild panic you get with belts as they come up to the change.
