Overheating in a 340 Utility

homebre973 · Jun 2, 2014

I have an IH 340 Utility gas tractor that overheats after 45 minutes to an hour. I know very little (nothing) about the cooling system. My guess is that it might be clogged and I would like to drain or flush it. What would be the best method? I do not know if there is an outflow valve or just a lower hose I can remove. Since the hose and radiator are quite old, I am hesitant to do anything that might need me to replace the radiator at present. What would be the safest course of action, and is the lower hose easily replaceable if it needs to be taken off? Is there a drain valve? Thanks

my 240u has a drain under the radiator. the least caustic method to flush, drain cooling system, give it a rinse with clean water and drain. get enough white vinegar to completely fill the cooling system. fill er up with vinegar, run it for 20 minutes or so, then leave it sit for a few days. then drain and flush again with clean water. then refill with antifreeze.

Thanks. If I cannot get the valve open without damaging the radiator, would you recommend taking off the bottom hose or is there anything else I could do? Thx.

On my 240U, the drain pipe is screwed into the cast elbow that's connected to the radiator on the left side. I believe the 340 is similar.

If the cap doesn't come off or the drain pipe doesn't come out, then what else can you do but remove the lower radiator hose? Other than take an axe to the radiator itself, I don't know of any other way.

However, either the cap will come off or the drain pipe will come out. It's standard pipe thread and there's probably oil all over in there, so it's not rusted up.

Any suggestions on how to loosen the plug without breaking it?
Thanks
