Detailed Description

Four Seasons 37448 is a temperature switch used in engine cooling fan control circuits. The radiator-mount design monitors coolant temperature and signals the fan system when the set temperature threshold is reached. For Jaguar XJ6 models from 1974 through 1987, this switch supports proper fan operation in a temperature-controlled cooling system. This part cross-references A03848 and C46305 for the same application.

What It Helps Solve

• Cooling fan that does not switch on at the correct temperature
• Fan operation that is inconsistent or intermittent
• Overheating caused by delayed radiator fan activation
• Faulty temperature signal to the cooling fan circuit
• Replacement needs for a worn radiator-mounted temperature switch

Installation Notes and Tips

Verify the connector shape, terminal count, and mounting location before installation. This part uses a rectangular, 2-terminal male connector and a system-mount temperature switch layout, so matching the original electrical connection and radiator mounting style is important. Confirm the vehicle is a 1974-1987 Jaguar XJ6 with the same temperature switch application before replacement.

Quality Assurance

Four Seasons identifies this part as meeting or exceeding OEM requirements for the listed application. Part number 37448 is built for temperature-switch service in the cooling system and is cataloged for direct replacement use on the specified Jaguar XJ6 fitment.
