Keep coolant flowing at the right temperature with the AISIN Engine Coolant Thermostat & Housing Assembly (THH-012). It drops in as a direct-fit replacement for the 2016-2017 Honda Accord equipped with the L4-2.4L engine, combining the thermostat and its housing in one ready-to-install unit.

A coolant thermostat regulates the flow of coolant between the engine and radiator — staying closed to help the engine warm up quickly, then opening to let coolant circulate as operating temperature is reached. The integrated housing locates and seals the assembly at its mounting point.

  • Thermostat & housing in one: supplied as a combined assembly for the listed application.
  • OE-manufactured for form, fit and function: built to match the original for temperature control and cooling-system performance.
  • Temperature regulation: designed to help keep coolant within its intended operating range.
  • Country of origin: Japan.

Signs the original thermostat may need replacing include engine overheating, running colder than normal, erratic temperature-gauge readings, or coolant seepage at the housing. Diagnose the cause before replacing.
