I know we have timing chains on the 3.5L. I was just browsing around the vividracing.com site and came accross a timing belt for the 350z? Is there a conversion to use a belt and if so, WHY? I'm not interested in making the switch, just curious.

I think that's just the regular engine belts. "timing belt" is a misnomer.
You are correct, we have a timing chain on our engines. It's under the timing cover which faces the front of the engine bay.

 

i was sure that all new Z's had timing belts.........

 

That's one heck of an expensive drive belt then. Thanks for the quick response. I can rest easy tonight now

 

alert newb post.

 

The link clearly shows those are drive belts off the crank pulley for the 350Z's a/c, power steering, etc. No details on why or how they are "super strong". The OEM belts (which should be relaced periodically) are not as expensive.

 

So since we have a timing chain, does that mean we don't have to change it ever? I don't see anything about it in the service manual.

 

No the chain does not need to be replaced.

The timing chain is considerably stronger and more durable than a textile belt. Its lifespan usually exceeds that of the engine, although I always replace them (together with the pulleys and guides) whenever I rebuild a motor.
