Running hot in San Antone

loss of power combined with the smoke colors are key here I think.

Fan belt tight? Sounds to me like a lack of airflow through the rad. Something blocking the airflow maybe? Problem is, if you overheated it more than once, the head gasket will be suspect. Diesels don't cotton to being overheated and will pop head gaskets among other things like cracked heads or cracked blocks in the deck area.

One thing I never do is allow my diesels to get overheated.

Today I heard someone say something about the thermostat. That to make sure it was installed and turned the correct way. I wasn’t sure what was meant by that. I opened the thermostat housing to see the position of the thermostat. It was placed straight with the engine. The thermostat spring was not centered and I was told to turn it where the spring would ace the engine, which would also be inlinebwith the housing. I also took radiator cap off to watch the glow of coolant after adding. I burped the hose some and continued poring coolant in until it finally started churning. Well lo and behold the tractor starts quickly with very little smoke at start up. I’m gonna watch it some to make sure but I think after all this that’s what it was, however, the tractor was started with all this trouble with the original thermostat and nothing wrong until all at once so I’m still not completed satisfied my trouble is over. What do you guys think?
