Make sure you have the proper tools:
6"-8" Extension
Nut driver/screwdriver (to remove coil packs)
Spark plug socket with retainer (rubber washer)
NGK spark plugs (bosch platnium plugs not recommended)
Do them one at a time to ensure the plugs are replaced accordingly
Spark plug gapper (ensure the plugs are gapped properly .044)
DENCO come pre gapped; do not scrap needle point plugs (ruins electrode)

Disconnect the battery, remove the spark plug covers and cable, and remove the old spark plugs. Put in the new spark plugs, replace the covers and cable, and reconnect the battery.
To change the spark plugs in a 2000 Suzuki Grand Vitara, first, ensure the engine is cool. Remove the engine cover if applicable, then disconnect the negative battery terminal. Carefully detach the ignition coil or wire from each spark plug, use a spark plug socket and ratchet to remove the old plugs, and install the new ones with the appropriate gap. Finally, reconnect the ignition coils or wires and the battery terminal, and start the engine to ensure proper function.
Diesel Grand Vitara engine problems can be caused by low-quality oil or coolant leaks. Fouled spark plugs can also cause the problems.
The type of plug that the Grand Vitara takes depends on the manufacturer of spark plug. For example the Iridium SK20PR-L11 or the Platinum TT PK20TT, with a gap of 0.044.
Could be time for a tune up, spark plugs, filters, etc.
Replace the spark plugs and plug wires. Replace the distributor cap & rotor. Replace the air & fuel filter.
I would replace the spark plugs after 50K, the wires and plugs again at 100K.
