Need Help - F24 Overheating

[normde2001]

Overheating is basically a common sense repair. The overflow system bottle has no bearing on it and only began appearing on watercooled engines in the mid '60's. before that they just dumped a few ounces of coolant on the ground to create room for expansion I don't see where you ever back-flushed the cooling system or blew out the fins of the radiator. If no sign of a HG leak, you have either a clog in the system or lack of airflow through the radiator.

I flushed the radiator, but not sure that's the same as "backflushing." The front of the radiator appears to be clean and dirt-free, but I can hit it with compressed air to make sure.

I thought I had this problem licked, but yesterday we overheated again. We weren't doing anything, really - mostly idling while we loaded some stuff into the bucket to put up on some high shelves in the barn - but it was over 90 degrees outside at the time it happened, if that matters. Looks like the tube connecting the radiator to the overflow came off a the radiator.

Is that connection supposed to be a press-fit, or is there supposed to be a hose clamp on it? Mine doesn't have a clamp; wondering if the solution is as simple as installing one.

A clamp wont stop anything. It just catches your coolant and alows it to return to the radiator once cooled through the siphon effect. If it blows off that means there is too much pressure it should easily flow as the radiator cap pops open a bit it sounds as if yours is blowing off and sending pressure. If you dont have the hose it will just flow onto the ground as cars and trucks did 30-40 years ago and no big deal, you will just be a little low on coolant once it cools. But this willnot cause you to over heat.

The temp does not help but your tractor should be able to work hard all day long at 90F not just idle around.

I would replace radiator cap after you have a shop test your radiator and they say its good. (just so you dont spend money on something that is not the problem). A bad radiator cap will pop to early not allowing the tank to pressurise and boiling to early. But i really dont think thats your problem. I think you have a bad head gasket or bad radiator!!!! quit driving it and trouble shoot it.

I think several of us may have said it IS NOT BECAUSE you were missing a thermostat, i am not discounting what the other guy said about that and its good to return it back to the way it was designed. But your tractor and a race car have very little in common, nothing about the way there operated is the same.

If it looks clear and you can see through it, its clean. Were talking seeds and grass and build up. When bushogging the radiators clog very easy on these tractors and can cause you to overheat very easily. I have done it once myself. Since then i stop every 45mins to an hour to check and clean my radiator to make sure there is no buildup on it. I once had a piece of window screen zip tied to the front grill. That hellped a lot but the briars and sticks ripped it off and i have not replaced it yet.

Wait 1 min.. His tractor and my drag car (as well as others I know) Have something in common... His tractor doesn't have a T.stat.. I don't know of anyone that runs a T. stat in their race car...

LOL... You Pro's Still don't have this tractor fixed? You guys are slipping...:thumbsup::laughing::laughing:

"Get the missing parts and the overheating should be fixed..":thumbsup:
Not much you can do if the man won't follow competent suggestions:confused3:

There are no missing parts. Go back and read the thread. All parts have been installed.

But you still havent pulled the radiator and taken it to a professional shop? Have you even pressure tested the Radiator with one of those pressure testers Carey was talking about? They loan them at places like Orielys or Advance auto parts. This will tell you if the radiator holds pressure and show you leaks. If it holds it could point you to a suspect cap. But i really think you have a blown head gasket and or a plugged radiator.

I dont remember and dont feel like wadeing through 45 posts or so on two different threads but did you confirm there is no bubbles in the radiator at initial startup to signify blown head?

I have done the pressure testing. Have not removed radiator. Radiator and cap both hold pressure (unless I was using the tester wrong). Not clear on checking for bubbles at startup... Bubbles where? In the overflow? Or do I remove the radiator cap and watch there?
