Well i have the radiator, it is a few inches wider than my current radiator but looks like it will fit ok, the hoses need to be modified to fit.
Overall my mechanic feels it will be fine as the later model radiator seems to have alot better cooling fins, holds more water and is bigger in size. The real test will be when i am sitting in traffic for 10 mins. The Sprinter used to overheat a bit when in stop/start traffic.
I will keep you posted.
