A customer called today. His big Detroit had developed a coolant leak. With the warmer weather he had unplugged the coolant heater to save electricity.
Bad move.
All iron expands with heat and shrinks when cooled. This engine shrunk enough to open coolant seals. He plugged it back in and the leaks dried up by the next day. This is a problem for all big iron. This is at a wastewater pump station. Join our group for discussions about emergency power.
