normal operating temperature for a H

Anonymous-0 · Mar 6, 2011

I have a 1951 H. What would be the normal or safe operating temperature for it.

If it is a pressurized system with a 7 or 7-1/2 pound cap, it can use a 180 degree stat. It has a pretty large bypass around the thermostat, and might never get that warm unless on tillage equipment, or a feed mill, pulling 20+ hp for an hour or so. They need to run hotter when operating on distillate (if that model) so they used shutters on the radiator, and high heat manifolds to vaporize the fuel. Almost all spark ignition engines engines run more efficiently at 200 degrees than they do at 160. Jim

With a new temperature gauge you will have to work your H pretty hard (disking on a hot day) to get the needle up into the Run area. Most of the time plowing snow or just puttering around it will be in the white Cold area.

So run a hot tstat if you don't work your tractor?

I replaced my temp gauge on my H because I thought it didn't work. Well the new one never moved either, until one day last year when I was working it hard brush hogging some 4ft tall weeds/grass on a 98-100 degree day, and it finally moved ALMOST up to the run area. I was shocked.

What temperature is the thermostat that IH dealers sell for an H? Do you have other temperature options?

I saw a 160 and 180 when I bought mine for the MD. Every letter series and the early numbers run the same tstat from what I saw.
Maybe you run the 160 in a nonpressureized radiator?
