Spark Plug changing/cleaning Options

[m0dd3d1]

I was thinking about taking out my plugs tomorrow but I was wondering, when I put them back in, do I need to torque them in?

Well I borrowed my Dad's torque wrench and I referred back to my Haynes manual, and is it just me, or does that manual suck? It's for Celicas 86-99, would that be why I don't have any real specific information on my car, like what to torque the spark plug to, and what size plugs to actually replace the old ones with? Or would it not say that anyways, and I'm just wishing there was something out there that isn't? Thanks for the help.

if your super super anal about it, you should buy a toyota manual and know every detail about your car. But the haynes manual is good enough to not destroy your engine. I also recomend using anti-seizing lubricant on the threads.


Remember, you tighten a new spark plug and a old spark plug differently because a used spark plug has its crush washer already crushed.


So my best way to torque down a spark plug is to hold the big end that lets you change the direction it turns in the middle of your palm and twist it as hard as you can. You wont be able to over tighten it and strip the head because you wont have enough leverage. I find this way its tight enough where it doesnt leak, which is good enough in my book.
