I have installed a flathead ford v8 on a 8n tractor but I have a heating problem can anyone give me some help
versized radiator installed? Good fan & shroud? Maybe electric fan?(quoted from post at 13:59:25 10/01/12) I have installed a flathead ford v8 on a 8n tractor but I have a heating problem can anyone give me some help
s that larger than N radiator? You know that the larger engine produces more heat. Retarded engine timing will put more heat into cooling system......might check static & advance mechanism(s).(quoted from post at 14:43:13 10/01/12) used ford 4 tube radiator with elec. fan
new water pumps. water moving fast in raditor
orry, but you can not demonstrate that theory.(quoted from post at 15:07:52 10/01/12) Does it have a thermostat installed in it??? If not that could well be your problem due to the fact the coolant does not have time enough to cool before it goes back into the engine so yep it runs to hot
orry, but you can not demonstrate that theory, either.(quoted from post at 15:33:27 10/01/12) Old is correct. These flatheads with two water pumps need thermostats to prevent overheating, otherwise the water flow through the radiator is too fast.
'll tell you the same thing I said before, until you have tested with, repeated without, and finally repeated with, you haven't really proven anything. A single change leaves too many other things that may influence your conclusion.....gotta have repeat, same results. If it was fine with a thermostat , then why did you take it out and make it overheat??? See what I mean. No disrespect Royce, but I just need real proof to go against a world of fact, science, physics, etc. Not to mention too many years of experience. Don't feel bad, I question everything/everybody.........that is how I have learned so much in 70 years!(quoted from post at 22:16:30 10/01/12)
Don't forget walking underneath a ladder.
I have never found an explanation, but I did have a '70 Ford van that would
overheat without a Thermostat.
It had the clutch pedal strapped to the floor since it now had an automatic
behind the 351 Windsor where the I-6 had been.
Pretty warm in the driver's seat too, since the doghouse wouldn't fit with the insulation in it!

How does it work & why? :wink:
can see the "sucked hose shut" situation and very likely something such as this occurrence is what has mis-led folks to the wrong conclusion of "removing thermostat caused too fast flow through the radiator to be able to remove the heat". A cause- effect mis-association.(quoted from post at 23:18:09 10/01/12) I've found in several instances, overheating occurs because the bottom hose sucks itself shut.. You need coil springs inside the hoses to prevent this. The fact that thermostats in the outlet hoses seem to help, is that they build up some backpressure, preventing the lower hoses from sucking shut. It probably indicates a pretty plugged up radiator core, which makes things worse.

This may very well be the explanation for what I experienced.
It was quite a while ago, but I do not recall replacing the lower radiator hose.
(quoted from post at 18:29:18 10/01/12) I have proved that with a Model A FORD powering a cord wood saw.No thermostat boil over,install a thermostat boiling stops.
(quoted from post at 18:49:30 10/01/12) Well, you haven't proven it to me yet. I'm still calling it one of those "things I've always heard & believed". Like "set battery on earth or concrete & it will such the juice out of it" or "break a mirror, 7 years bad luck", or "cross the path of a black cat & have bad luck". I've spent hundreds of hours studying thermodynamics and heat transfer & paid the tuition for it & speeding up flow through a heat exchanger (radiator) increases , NOT decreases or even remain equal, the heat transfer until you reach astronomical velocities & you won't reach those velocities by removing the thermostat! To do a decent test, you will need to test, remove & test, replace & test. Beyond the technical, I have removed many thermostats & operated without until convenient to replace & never have I seen anything but lower temperatures without one. Never! Furthermore, if a little extra flow is going to result in overheat as you claim, explain these numbers: Ford N tractors@ 16gpm, NAA@19gpm, '55Chev@48gpm, ZR1 Corvette@85gpm, GMC 305ci/[email protected] you think removing the thermostat will result in overheating!!! I'll be waiting a long time to see you demonstrate that! It is bull!
yth killing is very difficult. Some things have been repeated for so long that they become almost like fact, except no substance to back them up. For those without a completely closed mind, permanently set in concrete, facts will always rule the day.(quoted from post at 13:01:47 10/03/12)(quoted from post at 18:49:30 10/01/12) Well, you haven't proven it to me yet.
