Okay, I'm about at the end of the trail one way or the other now. At this point I've *very* carefully mixed my coolant. I've flushed the radiator and the block (independently) both ways (top to bottom and bottom to top). I've got a new fan belt. I've got new radiator hoses. Based on seeing the flow during flushing, it's difficult to believe there is any constriction or obstruction. I've adjusted the clutch.
After about 30-40 minutes of bush-hogging (even in *very* light grass/weeds), the temp light comes on. So I stop the machine and (with great care), open the radiator. It shows 205 deg F on my handy dandy candy thermometer. It has not boiled over.
So ... what's the best hypothesis at this point? Looks like the sensor is faulty? In that case I'm inclined to install a real thermometer to tell me what the actual temp is. Hoye seems to have one.
Has anyone reading this installed one of those? What exactly is the "overheat" temp on a 1700?
I don't want to spend money on a water pump if I don't have to, but I'm thinking that this 4' rotary cutter is probably close to limit for one of these little machines. Any thoughts?
How much of a pain is it to install the water pump?
