How do you change the three back spark plugs on a 1999 Toyota Sienna?
After posting my original to a question on a different forum, I’ve noticed how wiki.answers.com started posting this blog. So I thought I’d add comments here. Well, I had to change my plugs again… putting lots of miles on the Sienna. This time I did this in just 45 minutes! The one danger I’d advise here is the pulling of spark plug wires. I recommend that folks use plenty of spark plug lube on the heads to avoid sticking over time and easier removal the next time you gotta do this.
