How to replace the spark plugs on a 2000 vitara?
If it has the 2.0 litre 4 cylinder with direct ignition remove the igniter coil packs by removing the retaining bolts and pulling the igniter upwards to remove it from the plug. Do this for all plugs. Remove the plugs as you would normally (need a long plug tool or an extension). The number three can be tricky because of the strut tower brace, depending on the tools you use. Replace the plugs. It's recommended that you grease the plug boot before replacing. Check an auto shop for suitable grease. Replace the coil packs and tighten the bolts. Don't know what the exact torque should be, but don't strong arm them!
