Aveo 1.4LT 2009 Timing chain or belt?

Hi all.

I'm new here having just bought an Aveo 1.4LT 2009

I just want to be sure I don't make any expensive mistakes, so I want to determine if this engine has a timing belt, in which case what's the service interval for belt and tensioner replacement, or does it have a timing chain?

The maintenance book for it does not mention the timing belt for an Aveo, but the same book seems to also cover the Matiz where it gives a 60,000 mile replacement interval.

On the top engine cover it says "Eco Tec" if that helps identify what engine I have. Anything else I should look at to check further what engine variant I have?

Thanks.

EDIT

Looking at some of the service history with the car it says "Engine code G14D" if that helps?

Wow based on searching engine code I found something cool
