Keep the engine cooling fan cycling on cue with the Standard Ignition Engine Cooling Fan Switch (P/N: TS-318), a direct-fit replacement for the 1974-1987 Jaguar XJ6. This thermal switch senses coolant temperature and signals the fan controller so the cooling fan engages at the calibrated set point.

  • Custom wax actuation: a specified wax formulation expands when heated to trigger a snap-action electrical contact that transfers the signal to the fan controller.
  • Factory-calibrated: each thermal switch is calibrated and tested to confirm switch actuation, making electrical contact at its specified lower-temperature set point.
  • Bimetallic contact arm: a formed bimetallic arm uses the different expansion rates of two fused metals as a creep-action device for precise performance.
  • Robust build: high-grade materials designed to meet the demands of today's service professional.

Signs this switch may need replacing include a cooling fan that never turns on, runs constantly, or engages at the wrong temperature. If a failed fan switch is the cause, this replaces it; diagnose the circuit first, as these symptoms can have other causes.

Frequently Asked Questions

What vehicle does the TS-318 fit?

It is a direct-fit replacement for the 1974-1987 Jaguar XJ6. Check the Buyer's Guide tab to confirm the application for your specific vehicle.

What does this cooling fan switch do?

It senses coolant temperature and signals the fan controller to engage the engine cooling fan when the coolant reaches the switch's calibrated set point.

How does the switch actuate?

A custom wax formulation expands when heated to trigger a snap-action contact, while a formed bimetallic contact arm provides a precise creep-action movement.

What are signs this switch may need replacing?

A fan that never turns on, runs constantly, or engages at the wrong temperature can point to a failed switch. Diagnose the circuit first, since other causes are possible.

What other part numbers does this switch replace?

It interchanges with TFS563, SW1828, FS221, C46305, DAC2072, and DAC3061.
