[Farmall] water temperature in 48 super a

Wed Aug 11 17:47:45 PDT 2010

The sensor for the temp gage is in the return from the radiator to the engine, 
so it is sensing after being cooled. Most engines the temp sensing is in the 
head. Like Al says you have to get it pretty hot for the gage to move. If I get 
mine pretty hot I can hear the coolant bubbling in the engine when I shut it 
off, gage is still in cold area. The most important thing is to make sure that 
you have the cooling system full at all times to avoid over heating, so if you 
use it often keep an eye on it, it will "use" coolant. This system depends on 
natural convection to make it work, when the water is cooled in the rad it flows 
down, when the engine heats it up it rises, thus thermo-siphon term.

The enlarged hole sounds like a broken exhaust pipe at one time or another, 
pretty common.

In my experience you got to really get it hot to see much of a change in the 
gauge.  Your gauge's behavior sounds normal.
