Integrated Thermostat Housing Overview

The Motorad Integrated Housing Thermostat 954-180 is an OE-specification engine coolant thermostat housing assembly built for controlled coolant flow and stable operating temperature. It is a fitment-based replacement for select Acura cooling systems, including MDX and RDX applications.

  • OE supplier manufacturing with OEM-quality materials and processes.
  • 180°F thermostat rating for temperature control at the specified opening point.
  • Plastic, steel, and copper construction for housing durability and response.
  • Includes an O-ring seal and a bleeder hole for serviceable installation and air management.
  • Three-bolt housing design with one outlet port and one bypass passage.

Cooling System Function

This thermostat housing assembly regulates coolant circulation so the engine can reach and maintain its intended operating temperature. The copper case and wax compound are engineered for quick reaction to coolant temperature changes, while the integrated housing format simplifies replacement of the thermostat and housing as a single unit. Fits 2017-2020 Acura MDX and fits 2016-2018 Acura RDX. Part number 954-180 is the reference to verify before ordering, and 954-180 is also the Motorad identifier used for this application.

Common Issues It Can Address

  • Coolant temperature that stays too low or rises inconsistently.
  • Thermostat housing leakage at the seal interface.
  • Delayed thermostat response during warm-up.
  • Air trapped in the cooling circuit after service.

Installation Notes

Confirm the 180°F specification, outlet diameter, bypass dimensions, and bolt-hole count against the original part before installation. This assembly includes a gasket or seal, but mounting hardware is not listed as included. Use the vehicle service procedure to bleed the cooling system through the bleeder hole after installation.

Quality Assurance

Motorad manufactures this integrated housing thermostat to OEM specifications and safety standards as an OE supplier. The design uses OEM-quality materials and processes to support demanding cooling-system operation.
