1966 Ford 3000 diesel. Is there a way to tell if the coolant is circulating? I've put in a new thermostat, but the gauge still tells me the engine if overheating. I'm not sure I trust the gauge. The top radiator hose is hot when the engine is running, the lower hose is luke warm or even ambient temp. The radiator is in good shape and the water pump is also new. Fan shroud was purchased and installed with the new water pump.
The engine gives me no external signs of overheating, but I'm still concerned that the engine is too hot. I've measured the coolant while the engine was running hot, and it was lower than the 188 degrees required to open the thermostat. But if the coolant isn't circulating, then that temperature won't reflect engine heat at the sensor. Ideas?
