Iseki TE3210F overheating

[tobac]

I have a friends Iseki TE3210F tractor which is about 10 years old. Since new it has been overheating after around 1 hours work. Dealers have looked at everything but have been unable to resolve it. We suspect radiator may be too small for the use. Has anyone had any experience with this?

The Japanese radiators do not have any excess capacity. Has the radiator been flushed? It may need to be boiled out which may lead to some leaks. At this age it is probably pretty thin.

I have an FB 31 tractor made by Iseki and it did the same thing since it was new. Dealer could not find anything wrong so I put up with it. After 5 or 6 years the water pump started leaking and I replace it and it has never overheated since

The engine has been boiling since new and the dealers could not find any fault. What engine is in the FB31 as I don't know of it. Maybe the problem is similar.

Might sound crazy but, is the fan belt tight? I had a TS2205 and it was obverheating. I replaced the gasket from the engine to the water pump stopped overheating. Is thev engine lugging? Is the air breather clean? Do you keep the trash out of the raditor fins?

Thanks for the tips but they are all OK. It is an internal problem I believe.

Does this tractor have a thermostat? If it does, that would be the first to go for me...

[tobac]

Yes it does have thermostat and it has been changed.

Do you have a temp gun? When the tractor's high temp light comes on (if it has one) or when you think it's getting too hot, check the temperature of the inlet (top) and outlet (bottom) hoses to radiator and see what the differential is across it. Some people might try to feel hoses with their hand, but I'd recommend against this for a number of reasons.

If your tractor's temp light is on, it's probably pushing at least 230 deg F on the water to the radiator and if the radiator is working as it should, I would anticipate the outlet hose temp to be no higher than 180 deg F. Now I don't know what the actual design conditions call for, but if the temp is 215+ deg F coming out the bottom hose to the pump, then I'd have to say the radiator is the culprit.

This is an easy check and temp guns are getting fairly cheap these days and quite handy on all sorts of projects.
