300SDL radiator is NLA.

You filled the old radiator? I thought it is damaged by the clutch fan. If you did fill the damaged radiator then probably the coolant compartment and the transmission fluid compartment, below the radiator, is breached. Coolant drain out from the rear of tranny. I feel for you, the SDL changed from a daily driver to crap in a few days.
