Does the 2016-2017 3.5 have a timing chain or belt?

I have not found the answer to my question whether the new 3.5 has a timing chain or timing belt. Is it an interference or non-interference engine?

 

Chain

 

* 3.5L V-6 Non-Interference

 

Internals of the 2GR-FKS engine are of superior quality. Block and heads are aluminum, of course. Both the crankshaft and connecting rods are forged. The cams are driven by a long-life chain rather than a belt, and the rocker arms ride on needle bearings. Iridium-tipped spark plugs are good for 60,000 miles, and have a deep threaded section, which allows thicker material in the head at that point, which in turn allows coolant passages to be routed closer to the combustion chambers. Externally, the exhaust manifolds and pipe are stainless steel.

That's the one^^^, sorry about that.

 

Wait... I replaced my cat back exhaust and the OEM one was rusty... how did that happen if stainless steel exhaust?

 

SS does corrode. High temps in an oxidizing atmos. Road salt (chloride ion's) also attacks SS.
