Swivel Thermostat Hsng. GM & Mopar 1-1/2in Hose

The Swivel Thermostat Housing GM & Mopar 1-1/2in Hose is a critical cooling system component engineered for General Motors and Mopar vehicles requiring reliable temperature regulation. This thermostat housing assembly manages coolant flow and engine temperature control, making it essential for maintaining proper engine operating conditions. Whether you're restoring a classic muscle car, performing preventive maintenance, or addressing cooling system failures, this OEM-style replacement ensures your engine runs at peak efficiency while protecting against overheating and cold-start issues.

Built by CSR Performance, a recognized manufacturer of performance cooling components, this swivel thermostat housing features a 1-1/2 inch hose connection designed for direct fitment on compatible GM and Mopar platforms. The swivel design allows for flexible hose routing, reducing installation complexity and minimizing stress on coolant lines during engine vibration and thermal cycling. The compact footprint—measuring 4.3 x 4.3 x 4.5 inches and weighing just 0.85 pounds—makes it ideal for tight engine bay configurations without sacrificing durability or flow capacity. Cast construction provides excellent thermal conductivity and long-term reliability in high-temperature environments.

Mechanics, enthusiasts, and restoration shops rely on this housing for its straightforward installation and direct compatibility with factory cooling systems. It serves as a drop-in replacement for original equipment, eliminating the need for custom adapters or modifications. The 1-1/2 inch hose connection matches standard coolant line diameters found on most GM and Mopar applications, ensuring proper flow rates and system pressure integrity. Installation requires basic hand tools and cooling system knowledge; always drain your radiator and allow the engine to cool before beginning work for safety.
