Spark Plug Help for ES330?
Hey there,
Trying to change spark plugs since 20mpg average went to 17mpg. Want a few tips please:
I have the hex set needed to remove the 3 hex bolts holding the engine cover on. I tried taking one off with a hex wrench and one of the bolts snapped (Given I just ran the engine). Was this just stupid of me to do since the engine was hot? Should I wait for it to cool down? Just want some advice so I don't break another one. I let the enging cool down for a day or so and I just wanna know how to take them off the right way without messing them up. Thanks!
Eric

hey there I went to Autozone to buy spark plugs and it was successful. I tried taking off the engine cover but the hex bolts broke because I don't know why...I have to take the intake manifold off to get to the back 3 spark plugs and take the last hex bolt of the engine cover off so that's gonna be a lot of work. so far 2 of the 3 hex bolts have broken and it's very frustrating because I don't know what I can do to not break the third 1. I'm considering just breaking the last 1 on purpose in leaving the engine cover off, Lexus said that's okay. do you guys have any input because it seems like a really hard job for something that's as simple is changing spark plugs. thanks.
