I have a 06 IS350 and I am wanting to taking the engine cover off to look at the windshield wiper fluid bottle as it appears to be leaking, but I cannot figure out how to get the rivets out. I found some videos on youtube, that stated about pushing the center of the rivets in, then they pop out, but that does not seem to be doing the trick. Anyone be of assistance with this, without me just breaking them and buying new ones? :)
