Toyota Repair: Spark Plug change in Sienna 1998, independent repair, toyota sienna

Question
Hi Ted,
I needed some information on how to change the spark plug on the Toyota sienna V6, 3.0l engine from 1998 100,000 Kms. The outer 3 spark plugs have good access but the inner 3 plugs are very difficult to access. Can you please advice by a diagram how to get to this. Also advice at what milage the spark plugs need to be changed.

Thanking you in advance for your advice.

Sam

Answer
These spark plugs are platinum tipped and need to be changed at 60,000 miles, the rear plugs are very difficult to remove and I recommend that you have a toyta dealer or an independent repair shop perform this operation unless you have lots of tools to do this.
