Usually when working on a car with aluminum heads, I use Anti-sieze on the spark plug threads I haven't seen any reference to doing this on the Lexus. Is it not required?
Thanks

Ive always used anti-seize when replacing spark plugs in aluminum heads, its just good sense... However, in the million sets of spark plugs ive changed, none have ever had anti-seize on them... so its a toss up really... Personally, i would use it.. but i dont think its a factory recommendation.

 

i changed my plugs to torque masters and didn't use that stuff.. seems fine so far?

 

I always use antiseize. It's just a precaution.

 

Agreed with everyone here.. Always use it.. Dont forget the lug nuts as well!

 

I use it. It's only $1 so why not? Small price to pay if your plugs ever gets seized.

 

hmm. should i pull my plugs out and put anti seize on them? what's "seize"? lol

 

I would. Its not too late actually.

seize is basically "stuck". lol.

 

what are the chances of plugs gettin' stuck? what happens if they do get stuck?

 

Well, the chances of a plug seizing isnt super high, but that doest mean its not worth putting some anti seize on the threads. Basically, what happens is the steel plug and aluminum threads expand and contract with heat and cold... over time, the two metals could form a bond and cause the plug to become stuck... anti seize provides a barrier between the two different metals so that doesnt happen... chances are, you'll probably be fine... its all peice of mind i suppose.

 

ah - i'll ask lexus lol

 

you just did...

 

The anti-seize paste is used to prevent the spark plugs steel threads from seizing to the aluminum head threads. The seized aluminum threads, being softer, break off as the steel plug is removed. This causes the plug hole to become stripped out.

It's always a good idea to use never-seize when working with dis-similar metals, or where a rust condition may exist, like exhaust fittings.
