2N overheats

I was baling with my M the other day and it kept getting too warm and would not cool down like it should when idling.

I run the belts loose to make the water pumps last, but this one had gotten too loose, a little tightening and it is running good as new.

1) radiator over full. Only add enough fluid to just cover the top of the coils. The rest of the tank is basically a reservoir for expansion. Too much water = boil over every time.

2) Thermostat in backwards. If installed, the pointed end points towards the radiator and goes in the upper hose.

3) Trash in cooling fins. Take an air hose and blow the trash out from the engine side.

Hope this helps.

To help out, carefully (I don’t know if that is a pressure system or not) take the radiator cap off and run the engine and look to see if you have water flowing in the radiator after it warms up a bit. If so then chances are the water pump is working and the thermostat is opening. If you don’t have water flowing it could be either the water pump or the thermostat causing your problems.

If you have good water flow, then the radiator may be dirty either on the outside or on the inside. Back flushing might help, but if the radiator is dirty on the inside it will probably have to go to the radiator shop.

One other thing to check is the ignition timing. Late spark timing will cause an engine to run warm.
