The Automann 575.1013.1 is a replacement sight glass for the coolant reservoir (Automann part 575.1013) used on certain Freightliner and International heavy-duty trucks. It threads into the side of the reservoir tank, letting you visually check the coolant level instantly without opening the cap—helping to prevent overheating and engine damage. Over time, the plastic lens may become cloudy, cracked, or start leaking, so replacing it restores a clear, reliable view of the coolant. This sight glass has a 1/2 inch NPT brass thread for secure, corrosion-resistant installation.
