I am so stuck on this problem, and I am hoping one of you can help. I have a 2240 that is consistently overheating. My first suspiciion was the thermostat, so I replaced it with a brand new one from the JD Dealer. It didn't fix it however, and the radiator remains cold... The fluid from the engine is of course hot, but it seems the thermostat never opens as there is no flow through the top of the radiator. So I decided maybe it was the water pump. So I pulled everything apart (the entire cooling system including the radiator). Cleaned everything and flushed everything. The water pump was in perfect working order. So I reassembled the system, (including the thermostat) same problem. Radiator cold, engine hot. I removed thermostat, and sure enough problem was fixed (that made me consider maybe the new thermostat was bad). I put the new thermostat in boiling water, and it opened right up.
So I am lost.. water pump works.. thermostat appears to work,radiator is clean and not blocked but the flow from the thermostat never occurs when the thermostat is in.
Any thoughts?
