Detailed Description

The Motorad 233-160JV is an engine coolant thermostat engineered for OE supplier quality standards and manufactured to OEM specifications. Its copper case and wax element are selected for quick reaction to coolant temperature changes, helping the thermostat open and regulate flow at the specified 160°F set point. The offset design and air relief feature support proper installation and system bleeding in applications that require this configuration. This part cross-references Gates 23361 for the same application.

Compatible With 1971-1996 Jaguar XJ12, 1972-1977 Jaguar XJ6, 1979-1982 Jaguar XJ6, 1976-1992 Jaguar XJS, 1994-1995 Jaguar XJS, 1993 Jaguar XJRS, 1984-1986 Mazda RX-7, 1994 Saab 900, 1989-1993 Dodge D250, 1989-1993 Dodge D350, 1989-1993 Dodge W250, 1989-1993 Dodge W350, 1982 Nissan Maxima, and 1981 Nissan 720, depending on engine and cooling system configuration.

What It Helps Address

• Coolant temperature that runs higher than expected
• Delayed thermostat opening during warm-up
• Air trapped in the cooling system after service
• Inconsistent heater performance caused by poor coolant regulation
• Thermostat replacement needs on OE-style cooling systems

Installation Notes and Tips

Verify the thermostat housing style, bypass dimensions, and 160°F temperature specification before installation. The jiggle pin weep hole should be oriented to assist air bleeding where the housing design allows it. Because no gasket or seal is included, use the correct sealing component specified for the vehicle application. Confirm fitment against the exact engine and cooling system on Jaguar XJ12, Jaguar XJS, Dodge D250, and related listed vehicles before assembly.
