Keep your electric cooling fan responding to engine temperature with the Standard Ignition Engine Cooling Fan Switch TS-303. This coolant fan switch senses coolant temperature and makes electrical contact at its specified set point, sending the signal the fan controller uses to switch the fan on. It fits many vehicles, among them the 1995-1997 Volkswagen Passat, 1995-2001 Volkswagen Golf and 1998-2001 Volkswagen Beetle, as a direct-fit replacement for the listed applications. See the "Vehicles it fits" section for the full list.
- Quality control throughout: Standard Ignition is a global manufacturer of original equipment ignition products and keeps full quality control over the process, from components to the finished switch.
- Factory-calibrated set point: Each thermal switch is calibrated at the factory to make electrical contact at its specified lower-temperature set point.
- Tested for actuation: Units are calibrated and tested to confirm the switch actuates at its specified temperature.
- Built for the shop: A robust design and high-grade materials are intended to meet the demanding needs of today's service professional.
Signs this switch may need replacing include a cooling fan that does not come on as the engine warms up, a fan that runs all the time, or a rising temperature gauge in slow traffic. A failed fan motor, relay or wiring can cause the same symptoms, so diagnose the cooling system first. If the switch is the cause, the TS-303 replaces it. Follow the vehicle service information for installation, including any coolant draining and refilling.

Frequently Asked Questions
What does the TS-303 cooling fan switch do?
It senses coolant temperature and makes electrical contact at its specified set point. That sends the signal the fan controller uses to turn on the electric cooling fan.
Is this the right 1995-2001 Volkswagen Golf switch for my car's cooling fan?
The TS-303 is listed for the 1995-2001 Volkswagen Golf. Use the "Vehicles it fits" section to match your exact year and engine.
Does it also fit the 1995-1997 Volkswagen Passat and 1998-2001 Volkswagen Beetle?
Yes. It is listed for the 1995-1997 Volkswagen Passat and the 1998-2001 Volkswagen Beetle. Use the "Vehicles it fits" section to match your exact year and engine.
How is the switch calibrated?
Each unit is factory-calibrated to make electrical contact at its specified lower-temperature set point. It is then tested to confirm it actuates at that temperature.
What are signs the cooling fan switch may be failing?
Common signs are a fan that won't come on as the engine warms, a fan that runs constantly, or overheating in traffic. Fan motor, relay or wiring faults can cause the same signs, so diagnose first.
