Motorad 992-180 Engine Coolant Thermostat Housing Assembly

Overview

The Motorad 992-180 integrated housing thermostat is built for cooling-system service on select Cadillac applications. It combines the thermostat and housing in one assembly and uses OEM-quality materials and manufacturing processes for a direct replacement-style repair.

This Motorad 992-180 thermostat housing assembly is specified for 180°F operation and includes a bleeder hole, O-ring seal, and metal gasket material for a secure coolant seal.

Key Features

• Integrated thermostat housing assembly for streamlined cooling-system service
• 180°F thermostat specification for OE-specified temperature control
• Aluminum, steel, and copper construction with a silver finish
• Bleeder hole included for coolant system bleeding during service
• O-ring gasket design with metal seal material
• Three-bolt housing with two outlet ports

Detailed Description

Motorad designs the 992-180 with OEM specifications and processes, using a copper case and wax compound for quick response to coolant temperature changes. The integrated housing format reduces the need to service separate thermostat and housing components, while the sealed design supports consistent coolant flow management in demanding engine cooling systems. This part cross-references Dorman - OE Solutions (e.g., 902-2123) for the same application.

Compatible With Cadillac CTS and Cadillac ATS applications, this thermostat housing assembly is also listed for Cadillac CT4 coverage. Use the 992-180 when replacing a worn or leaking coolant thermostat housing assembly on these vehicles. The 992-180 part number is also useful when confirming the correct OE-style replacement during parts lookup.

What It Is Used For

• Replacing a leaking thermostat housing assembly
• Restoring proper coolant temperature regulation
• Addressing coolant seepage at the housing seal
• Correcting slow thermostat response in the cooling system
• Servicing an OE-specified 180°F thermostat application

Installation Notes and Tips

Verify the engine cooling system is cool before removal. Confirm the outlet diameters, bolt-hole count, and gasket style match the original part before installation. The included gasket or seal should be seated evenly to prevent coolant leaks, and the bleeder hole should be used during refill and air removal procedures. Fitment includes 2022-2025 Cadillac CT4, 2014-2019 Cadillac CTS, and 2016-2018 Cadillac ATS.
