Detailed Description

This Motorad thermostat is engineered for vehicles that require stable coolant regulation under everyday driving and higher thermal loads. The copper case and wax element are selected to react quickly as coolant temperature changes, helping the engine reach and maintain its intended operating range. Motorad 726-180 is a practical replacement choice for Hyundai Elantra, Hyundai Sonata, Kia Forte, Kia Soul, and other listed applications where a 180°F thermostat with seal is specified.

The Standard product line focuses on OE-style fit and function, using OEM-quality materials and manufacturing methods. That makes this thermostat a straightforward option for routine cooling system service on Hyundai and Kia models, including long-tail applications such as a 180F thermostat with seal for 2015-2019 Hyundai Sonata or 2016-2020 Kia Optima.

This part cross-references Dayco 72680 and Four Seasons 57268 for the same application.
