On Changing 2000 Sienna Spark Plugs
Going to be changing the spark plugs on my 2000 Sienna with 145,000 miles using Denso SK20R11 plugs in a few days.
The front three are clearly easy, the rear two on the drivers side look doable but the one on the passenger side has me concerned. I've seen a few things looking around online:
1) the use of a rubber hose to remove and install the plugs finger tight. Of course, that's after loosening and before tightening them. This looks desirable, especially in a tight area. Is it advisable?
2) a mention of a rack of some sort on the back three that involves removing bolts to gain access to the plugs. I didn't feel anything like that doing an exploratory. Does it exist on a 2000 model?
I'd rather not remove the wipers and the whole plastic assembly unless totally necessary. Any words of experience to share before I start? Do I need to blow the holes out with compressed air before removing the plug, or does the seal protect the cavity from debris?
Thought I saw some instructions on this site awhile back, but couldn't find anything significant.
