I've noticed that my cooling fan kicks in excessively - like when the gauge reads that the engine is at 'normal' temperatures. It only stays on for a few moments, usually when I'm idling (like in a drive thru) and shuts off - and it doesn't appear to lower engine temp like with my SC2. I can imagine that the engine is warm after driving on the highway, and having it kick in that long should cool it down sufficiently - but I'm not seeing any change in the gauge and it does it when the engine reads cool too.
Also I'm hearing a clicking noise from 'under' the car when at stop lights - I think I saw someone else once post something about it and everyone blew it off as exhaust system contraction - but it definitely doesn't sound like that and will come on when the car is idling on my lunch break in 25'F weather - definitely not cooling down from a long drive as it shouldn't be changing temp at all (unless the fan is causing it?) - also the lights dim momentarily with the click noise. It happens about once a minute to once every few minutes.
