I have 1972 Ford 4000 3-Cyl gas with a cooling problem. I flushed the radiator, which seems to have decent flow (thought it's pretty old and some of the fins are bent). The tractor starts up fine, usually blows one puff of white smoke until it gets going and then the exhaust is clear. After about 600' running my 4' roto-tiller or two bottom plow I start boiling over and loosing coolant. I've replaced the thermostat, radiator cap and radiator hoses.
Is it worth replacing the radiator and water pump? When I run the tractor without the radiator cap I see slight ripples in the top of the radiator. Does this indicate full flow? How rapidly should the water be moving? Also, so far I haven't seen any bubbles in the coolant. Which I'm hoping is a good sign.
Also, I have a serious issue with pressure in my gas tank. After about 3-4 hours of running the tractor, pressure builds up in my gas tank and it starts to act like it's out of gas. I replaced the gas cap with a replacement from Napa, which claims to be vented, but there's no difference. Any ideas?
