Noticed when I parked tonight a small hiss coming from the front end of the car and looked under to see it was dripping a bit of coolant, sounds like it's coming from the front my guess is one of the hoses at the bottom of the rad, I've recently had a new rad and gearbox oil cooler but think a pipe has split, does anyone have a cooling system diagram?, so I can remove the bottom cowling and have a good look in the morning, it's a 2003 model 4.4.
