My temps haven't increased. Always right where's it's supposed to be...
Oh...and I've never once had to have my A/C recharged in 16 yrs. It still blows cold air. Not trying to be a jerk, but serously...we have 2 other cars, and I don't sit there pulling the bumpers off and cleaning them off either, and they still work fine too. I mean, if you want to do it, it's fine...it's your car, but I just don't see a need. I did it once before thinking it would make a difference since people were saying it needed to be done, but nah, no thanks. Then again, people say I need to swap out my original IMS for a beefier replacement or add in an oil feed line, but nah thanks to that too. I ain't fixing what ain't broken...
