Ok guys, i was cleaning the engine yesterday of my C36 and noticed that the top hose coming off the radiator was squashed/crumpled/vacum sucked flat. The lower one is ok (nice and round). Both hoses lead into this metal thingy. I started the car and everything was cool. I then checked this against my 300E and the E class is definitely not squished. The hose is still soft but it's squished...What gives?
