The Motorad 7354-192 is designed to respond quickly to coolant temperature changes and includes features that support reliable operation in everyday driving.

Key Features

• 192°F thermostat opening temperature for OE-specified cooling control
• Fail-Safe design locks open if overheating occurs to allow coolant flow
• Copper case and wax compound for fast temperature response
• Offset design with air relief valve where applicable
• OEM-style seals included where applicable
• Jiggle pin weep hole for air bleeding during service
• Motorad Fail-Safe line for OE-style thermal management

Detailed Product Overview

Motorad part number 7354-192 is an engine coolant thermostat engineered to match OEM specifications and manufacturing processes. It is built with a copper case and wax compound to react quickly as coolant temperature changes, helping the engine reach and maintain the proper operating range. The Fail-Safe design is intended to lock in the open position if the thermostat is exposed to overheating, allowing coolant circulation to continue.

This thermostat is used across a wide range of vehicles, including 2006-2008 Ford Fusion, 2003-2008 Mazda 6, 2006-2011 Mercury Milan, and 2001-2007 Ford Escape. This part cross-references Four Seasons 73549 for the same application.

What It Helps Address

• Engine running too cool or too hot due to thermostat wear
• Delayed coolant flow during warm-up
• Temperature fluctuation from a sticking thermostat
• Overheating risk when the thermostat fails closed
• Air trapped in the cooling system after service

Installation Notes and Tips

Verify the 192°F temperature rating and sealing dimensions before installation. This thermostat does not include a gasket or seal, and no installation tool is included. The jiggle pin weep hole should be oriented to help purge trapped air during filling, and the cooling system should be properly bled after service. Confirm the bypass dimensions and flange measurements against the original part when servicing Ford Fusion, Mazda Tribute, Mercury Mariner, or similar listed vehicles.

Quality Assurance

Motorad manufactures this thermostat with OEM-quality materials and safety standards as an OE supplier. It is produced to OEM specifications and processes for consistent fit and thermal performance in the listed applications.
