Removing stock intercooler

Does anyone know a step by step process on how to remove the stock intercooler. I know how to get the bumper off but not sure how the intercooler comes out any lines need to be disconnected and does it come out from top or bottom. I need to clean it out had dealer replace the whole throttle body intake at 74000 miles, due to missing orange valve under warranty of course but they never flushed intercooler told me was needed to be done and Im getting oil in the throttle body again orange valve is there and valve cover is still working correct no hiss noise. Yes valve cover was replaced at 66000 miles or so now have 85000. Any input would help. Thanks guys
