I am looking at a used 2006 GS300 for my next car. I know it has a unique 3.0 V6 engine (discontinued after 2007 with the introduction of GS350). Toyota doesn't seem to be using this engine in any other cars in the U.S.

Does it run on timing belt or timing chain?

When I bought my 2006 GS300 AWD, the salesman told me it ran on a chain.

AllData service manual says it is a chain.

Its a chain, chains lasts alot longer, and not that much louder....

boaclub923

well, it "sounds" like a chain to me...
i'm not sure if it's the reason,
the sound of gs's engine is very different than camry...
so, i guess it's caused by the chain

are you referring to the direct injection click sounds?

I think the Camry V6 has a timing chain too.

TLPLEXUS

The current Camry 3.5L V6 runs on a chain. The model(s) before runs on a belt (3.3L and 3.0L MZ-FE type engine).

Thanks guys for clarifying the engine chain question. I will start looking for my GS300 soon.

Also the direct injection makes a different noise...lol, does the GS300 hav direct injection, im not sure..any wayz the GS is a great car no matter the number after it....

Regardless of being a timing chain, it too needs servicing as well.
