Has anyone changed spark plugs on 2001 Suzuki grand vitara? V6 4X4 if so where are they? and any other tips?

3 on the right side of the engine, 3 on the left. Between the cam covers on each bank of cylinders, almost directly beneath the edge of the big plastic housing on top of the engine. A good socket set, with a couple of U joints, and it should be an easy job.

You will have to remove the plastic cover to get to the spark plugs of both side. YOu wo not see spark plug wire, but small electrical wires coming out of each.

l would go with original NGK, Denso or Bosch platium

Remove 2 Phillips screws holding down the plastic covers on each valve cover. Under the covers will be 3 C.O.P. is ( Coil On Plug) disconnect the wires to each & remove screws using a 8 mm socket with extensions & ratchet as needed. Twist & pull to remove coils from the spark plugs. New rubber coil boots can be obtained from any parts house. Spark plug removal is now the same as any other vehicle. They r platinum plugs. If u find oil inside any of the spark plug tubes then u will also need to plan on doing valve cover gaskets, this is a MUCH bigger job!
