A Saturn SL -- and every S-series Saturn -- has a 1.9 liter 4 cylinder engine. The SC2, SL2, and SW2 have a DOHC (dual overhead cam) engine; the SC1, SL, SL1, and SW1 have a SOHC (single overhead cam) engine.
All of the 4 cylinder Saturns use a timing chain. All of the 6 cylinder Saturns use a timing belt.
If it has a 4 cylinder engine, there isn't one. If it's a 6 cylinder, I'm not certain.
The 6 cylinder Saturns were equipped with the "Ecotec" engine, which used a timing belt. Timing belts fail over time, and Saturn recommends that the belt be replaced every 100,000 miles. The 4 cylinder Saturns all used timing chains. With recommended service and normal use, the timing chain should not fail. It is recommended that you replace the timing chain and sprockets whenever the engine is rebuilt, but otherwise, the timing chain is considered to be quite reliable.
The miles per gallon for the Saturn Vue varied by the model of the Vue in question. For example, the Vue 6 cylinder, 3.5 Liter engine got a combined 18 MPG, as opposed to the 4 cylinder, 2.4 Liter engine which got 28 MPG combined.

Some cars that have a 6 cylinder engine include the 2013 Toyota Camry, which comes with either a 4 or 6 cylinder engine. Another car that has a 6 cylinder engine is the 2013 Ford Mustang. The Mustang comes with either a 6 cylinder or an 8 cylinder engine.
The V6 in the Saturn VUE is sideways (FWD) vs. the version used in the Cadillac Catera (RWD). On the Saturn, the crank sensor is mounted on the front side of the engine, sort of near where the trans mounts to the engine. Pretty easy to change.
According to the Gates website ( they make timing belts etc. ) the 3.0 liter - V6 engine in a 2003 Saturn Vue has a timing BELT
