It is a direct-fit option for applications such as Jaguar XJ6, Jaguar XJS, Jaguar XJ12, Mazda RX-7, Nissan Maxima, and Dodge D250 cooling systems that call for a 180F thermostat.

Key Features

• 180 degree F start-to-open temperature for standard engine cooling operation
• OE supplier construction using OEM-quality materials and manufacturing processes
• Copper case and wax compound for quick response to coolant temperature changes
• Offset design with air relief valve for improved system bleeding where applicable
• Jiggle pin weep hole included
• Standard type thermostat with OEM-style sealing features where applicable
• Motorad 233-180JV part number for catalog and cross-reference lookup

Detailed Description

Motorad Standard 233-180JV is engineered as an OE-spec engine coolant thermostat for vehicles that require a 180 degree F opening temperature. The copper case and wax element are selected to react quickly as coolant temperature changes, helping the engine reach and maintain its intended operating range. This thermostat is a practical replacement choice for older cooling systems in Jaguar XJ6, Jaguar XJS, Jaguar XJ12, Mazda RX-7, Nissan Maxima, Nissan 720, Saab 900, and Dodge D250, D350, W250, and W350 applications listed in the fitment data. This part cross-references Gates 23381 and Carlson 14058 for the same application.

What It Helps Address

• Engine running too cool because the thermostat opens at the wrong temperature
• Temperature fluctuation caused by a worn or slow-reacting thermostat
• Coolant flow control issues in aging OE cooling systems
• Air trapped in the cooling system during refill or service
• Replacement needs for 180F OEM engine coolant thermostat applications

Installation Notes and Tips

Verify the sealing flange dimensions, bypass dimensions, and 180 degree F temperature rating before installation. The thermostat uses a jiggle pin weep hole and an offset design, so align it according to the vehicle service procedure and coolant flow direction. No gasket or seal is included, and no installation tool is included. Always inspect the housing, sealing surfaces, and coolant condition before reassembly.

Quality Assurance

Manufactured by an OE supplier with OEM-quality materials, this thermostat is built to OEM specifications and processes for dependable cooling-system service. The copper case, wax compound, and OEM-style design details support consistent operation in demanding automotive cooling systems.
