chain
It has timing chain and gears. NO BELT
The k24t motor has a chain. That is the 2.4 litre, 4 cylinder motor. From what I remember - The V6 is also a chain.
There is no timing belt in that engine. It has a timing chain.

You must change it every 60,000 miles. Warning: This is an interference engine and as such if the belt breaks you will have very expensive internal engine damage.
HOW DO I INSTALL A TIMING BELT ON A 4D56 ENGINE
there is none. fortunately you have a timing chain on your car (I also have a '99) and it lasts forever. well, almost forever. I had one on a Toyota pick-up, 1980s vintage. eventually it came through the timing chain cover -- but never broke. it had over 200,000 mies on it at that point. something else killed the tuck, not the timing chain.
I'd pick up a Haynes or Chilton manual for your truck. They generally have good pics and procedures.
