It’s boiling over. The light never can on. The radiator is clean. Fan runs when the machine is running. It took hour and a half to over heat at 70 degrees.
Thermostat, water pump impellor blades rusted away or broken loose from shaft, plugged radiator (rust), collapsed or kinked lower radiator hose. Good luck.
Update. I saw the radiator cap gasket was crackin. So I put a new cap on. The fan belt looked to have 6” of play. I tightened that. The amount of air flow out the back when up ten fold. In the end, it hasn’t blown out any coollent since. I’ll post agin if the problem returns. Summer is still ahead.
