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.
