Changing Sparkplugs

Recommended Posts

Hello Everyone!

Please help with ADVICE!

I need to change spark plugs on my 1992 ES 300. The problem is: I can't figure out WHAT WRENCH I need to use in order to

open plastic cover ( with Lexus logo on it) above ???

Any suggestions to the process are very welcome as well!

It is still GREAT car after 14 years and 203000 K.

I forget.

It's just an allen wrench. Most likely 5-7mm. Just go buy a cheap metric set. You need a 7-8mm to get the upper intake manifold off & a 10mm to take the transmission fluid drain off anyways.
