I have a 2008 fleetwood Excursion with a rear radiator and a 360 hp ISC engine. There is a small leak that appears to be coming from the center of the engine below the front fly wheel or damper I thin...
I was plagued by a tiny leak in my cars cooling system on the way to New York state over Christmas. I finally filled the cooling system to the top and hooked up a cooling system pressure tester to where the radiator cap attaches and pressured the system up to 16#'s pressure. Only then did I finally find the leak!
Picture of what I found buried amidst all the mechanical engine clutter!
BTW I was able to borrow the testor from O'Reilly Auto Parts.
