I had Rocco change a clutch fan back in January b/c he noticed it wasn't working.
He saw one of my threads addressing an issue with the clutch fan, and he PM'ed me telling me to bring it by (I didn't even mention his name in the thread).
Turns out it was defective and he changed it under warranty. Also noticed my belts were shot and changed em all within the blink of an eye.
I forgot to mention I didn't even have an appointment and he was still able to attend to me almost as soon as I got there despite being busy.
