You had better take a good look at it and see what is in the way. I have changed a belt on a Suzuki Aerio - they are not the same necessarily - but you may have to remove an engine mount support to get to it. in that event you need a floor jack to raise the engine off the mount. then you have to rotate the tensioner back and hold it so you can get the old belt off. (assuming it is spring loaded). If you don't have a floor jack and a pretty complete set of tools - better not attempt it. Getting the motor mount re-attached and lined up is pretty tricky.
