Detailed Product Description

The Motorad Standard 268-180 engine coolant thermostat is a standard type thermostat featuring a jiggle pin weep hole to allow air to escape from the cooling system, preventing air locks. It opens at 180 degrees Fahrenheit, which is critical for maintaining the correct engine operating temperature. The thermostat’s sealing flange outside diameter measures 2.52 inches, with a height between flanges of 1.75 inches and an overall height of 2.5 inches. The bypass diameter and length are 0.98 inches and 1.88 inches respectively, allowing proper coolant circulation during engine warm-up. The flange thickness is 0.05 inches, ensuring a secure fit within the housing. This thermostat does not include a gasket or seal, so a compatible gasket should be sourced separately during installation.
