Compatible with Chevrolet Vectra, Saturn L300, Cadillac CTS, Saab 9-5, and other listed applications, this integrated housing thermostat is built with OEM-quality materials and processes. The copper case and wax compound are used to deliver quick response as coolant temperature changes.

Key Features

• OE supplier manufacturing with OEM-quality materials and safety standards
• Integrated housing thermostat design for simplified replacement
• Copper case and wax compound for fast temperature response
• Rubber seal material for sealing at the housing interface
• Two-bolt housing with one outlet port
• Starts to open at 192 degrees F

Detailed Description

Motorad 349-192 is a thermostat housing assembly for cooling systems that require precise coolant flow control and a secure housing seal. The 1.41-inch outlet diameter, 1.18-inch bypass diameter, and 0.88-inch bypass length support the specified cooling circuit layout, while the included seal material is rubber. This part cross-references Monroe Shocks & Struts (e.g., NI) for the same application.

Use this thermostat housing assembly on compatible Chevrolet Vectra, Saturn L300, and Saab 900 applications when replacing a worn or leaking housing, a thermostat that opens too late, or a seal that no longer holds pressure. The Motorad 349-192 part number is also useful when matching an OE-style replacement by catalog reference.

What It Is Used For

• Stopping coolant leaks at the thermostat housing
• Restoring proper engine warm-up and temperature regulation
• Replacing a housing with damaged sealing surfaces
• Addressing overheating caused by thermostat response issues
• Correcting pressure loss from a worn rubber seal

Installation Notes and Tips

Verify the outlet diameter, bypass dimensions, and bolt-hole count before installation. Clean the mating surfaces thoroughly and inspect the cooling system for contamination or damaged hoses before fitting the new housing. Confirm the application by part number 349-192 and vehicle listing before service.
