The 16v is a NON "interference" engine.
X2!
Both the G13 (Samurai) and G16 (Tracker/Sidekick) engines are
NON-INTERFERENCE ENGINES.
While full of interesting twists and turns, changing the timing belt is not a difficult task. It takes a lot of careful disassembling and reassembly of stuff but it is not beyond the abilites of the typical shade-tree mechanic.
Follow the instructions found in various available Haynes, Chilton or downloadable FSMs and make sure that you set the distributor timing so that the rotor points to #1 cylinder with the #1 cylinder at TDC
AND the #1 valves in the closed or ignition position.
No matter how you follow the cam to crank orientation procedure (the point of major confusion in setting timing), as long as you get it set so that #1 is TDC with valves closed every other revolution you'll be okay. I always position my camshaft/crank marks so they point up.
Hope that this helps!
