That engine is not sleeved, so the cavitation problems common to sleeved engines ala holes in the sleeves (allowing coolant to enter the combustion chamber) is minimized. But it's still not a bad idea to add an inhibitor, or if the freeze is real cruddy, just drain, flush and refill like your car. I have 40 year old tractors and after picking up on Sea Foam from a boating site, I gave my engines a bath in it; like a whole 16 oz can to a tank of diesel and did it a couple of times. Also, I have used diesel additives, and Marvel Mystery oil for years. But this stuff was amazing. It cleaned up my exhaust and has made cranking very easy cause, for one thing, it eliminates carbon in the combustion chamber and carbon clogs your injectors and rings. Try it, you won't be sorry and it is one heck of a lot cheaper than an overhaul. Biggest thing on a diesel to determine overhaul requirements, is how well does it start when the temp is 70F or above. If it kicks right off, you are in good shape. If you need ether at that temp you are dead meat....BTDT The year is correct. They started making that 3 cyl in '65 and it is one tough, fuel efficient engine. Need more, ask, Mark
