Hi
you posted a question on your 3750 and a leak behind the dash area. I also have a 3750 (1988 vintage) and also had a leak that I traced to the same area. It turned out to be a freeze plug on the rear of the engine block that had corroded and started to weap. A 50cent plug from kubota fixed the problem but it was a real bear to get to it, lots of time, cursing ad determination.
