'07 V6 - Timing chain or belt?

[geoff5093]

Im not sure whether the Gen6 V6 has a chain or belt. Some people on the forum have said it's a chain, while people at the Toyota dealership said it's a belt. Does anyone have actual proof that it's a chain/belt, like a Haynes manual?

My dealership told me it is timing chain!!!

Chain.

CHAIN SUB-ASSEMBLY (2GR-FE)

Ok, so I wouldnt need to make sure the timing belt (since there isnt one) gets chagned at around 90K miles, which is good since it's pretty expensive, lol.

And the chain should last the life of the car?

Exactly, Timing Chain will never have to be serviced. Unless something terrible goes wrong and it breaks... Very unlikely, Maybe at 500k

Thanks alot JSM, that saves me from worrying about it when ~90K comes around

hmmm, I wonder what the I4 has?

Thats why I was confused, because they said the I4 was a belt, but people here said it was a chain. And since it has the same engine as the Gen5 I4, I thought it was a belt, but now that I saw some proof, im happy

Another good reason to take what salesmen say with a grain of salt. Carmy I4's USED to have a belt, but changed some time ago.

The tensioner can go bad a lot sooner than that, necessitating a full timing chain service to correct the problem. Chains are a lot harder to change than belts since they are lubricated by motor oil.

How often would that happen? Hopefully not within the same range as a timing belt...

A timing belt service on most cars are expensive only on the labor. Parts are cheap. I think you'd still need to change the waterpump.
