MT

Just a little side note here -- if you installed antifreeze and did not premix the water & antifreeze before hand, drain it out, mix it and then reintall. The specific gravity of antifreeze is some 8 to 12% greater than water. It is HEAVIER! Thermo-siphon works on the idea that hot water is lighter than cold water, thus it will seek a higher level. As it does, cooler water is pushed out of the radiator back into the engine. If the heavier solution of mostly antifreeze is positioned in the lower part of the cooling system, THERE is where it will STAY -- blocking circulation!

These are good lessons for all who restore, refurbish or spruce up an old tractor. Hot water testing of a temp gauge is a simple affair if you do it before it is installed -- then you know!(PatB)

The guys are right on, but let me make a couple of suggestions and notes.

If it is cold where you are, you probably will not get to that high operating range 190 - 210 unless you really "load-her" for an extended timeframe. Also, the temp sending gauge us on the water manifold & under the hood, so it will read a higher heat than the actual fluids.

Since the MT does not have a water pump and it was originally spec'ed for water only, here are a couple of suggestions:

1). Only put in distilled water so you do not initiate mineral deposits in the cooling system.
2). Depending on how cold it gets where you are, do a blend of 30% anti-freeze, 70% distilled water to start; colder, increase your anti-freeze...etc.
3) Always pre-mix both your antifreeze and water before you add it to the radiator [no water pump does not mix it well]
4) Make sure your rad core is good and does not leak...

good luck,
