I have a 51 Case LA that I recently purchased. It runs great, but when plowing with it this past weekend, steam came out of the radiator cap at a very quick pace. I realize the machine is getting hot, but what can be done to resolve this? The fan is turning, air is being pulled through the radiator. It has water/antifreeze. Does it contain a thermostat? Are the insides of the radiator clogged? Could it be a cracked head? Since it appears to be Case LA day here, maybe I can find an expert. Thanks for the help in advance!

One LA I worked on had a thermostat in the neck between the radiator and the head. Just unbolt and take a look. Also check to make sure your fanbelt is tight.

IM NOT SURE WHAT PROBLEM YOU HAVE THERE. IT IS ALWAYS IN MY EXPERIENCE TO CALL THE MANUFACTURER AND FIND OUT IF THERE IS ANY WARRANTY AVAILABLE ON YOUR UNIT. IT SOUNDS LIKE TO ME IF WARRANTY IS NOT AVAILABLE THEN YOU MAY WANT TO SWING THE ENGINE WITH A REBUILT ONE FROM AUTOZONE. THEY HAVE VERY NICE REBUILT JASPER ENGINES THERE. IF YOU HAVE ANY MORE QUESTIONS JUST LET ME KNOW. THANKS.

Funny my parts book also shows the thermostat but the drawings show no place for it to go. I have a 45 and 48 and niether have a thermostat they use the radiator shutters. I wonder if the book could be wrong.
If it was tractor and knowing what I know about the LA's I would take the head off and raditor off and and clean and check the whole system before you do any real damage to the engine.
There are many problems with the cooling system on the LA that will only show up under heavy working. Walt

The LA doesn't have a thermostat. Heat is maintained by shutters. It may have shutters closed. Check this before you do anything else... Gene

IT could be a thermostat, but my guess is a plugged core. Drain it, fill it with vinegar, yes, plain old vinegar, warm it up, let it set a day, drain it, and then back flush it through the drain pipe.

It's possible that the engine block is full of rust, in which case you are looking at a major and expensive teardown as gaskets now run over $300.00 a set.

It could also be a bad water pump and I don't know of a source for parts or rebuilt ones for the LA.

I expect the radiator core is plugged up. Rust flakes etc do this. If the vinegar treatment suggested doesn't work, take the radiator apart and clean it - or have a rad shop do it if you are not comfortable tackling it. I've had to do this a few times in my farming life with L and LA tractors.

I would try to disassemble and reassemble it myself if possible as our local radiator shop charged me $300.00 to do it. Once it's apart they shouldn't charge that much just to boil it out.
