Detailed Description

The Motorad 328-180 is an engine coolant thermostat engineered to match OE temperature control requirements. Its 180F opening point is appropriate for vehicles that call for a standard 180F OEM engine coolant thermostat, including select Honda Civic, Honda HR-V, Acura ILX, and Acura EL applications. The thermostat’s copper case and wax element are built to react quickly as coolant temperature rises and falls, helping maintain proper engine warm-up and operating temperature.

This Standard line thermostat is manufactured to OEM specifications and processes, with an offset design and air relief feature where applicable. The sealing flange outside diameter measures 2.05 in, height between flanges is 1.54 in, overall height is 2.2 in, and flange thickness is 0.05 in.
