Temperature Switch, radiator fan

The Temperature Switch, radiator fan (400 703) activates the radiator fan based on coolant temperature. Replacing it restores proper cooling system operation and prevents overheating.

FAQ

A temperature switch for a radiator fan is a sensor-controlled switch that activates the cooling fan when a specific temperature is reached. Its function is to ensure the fan turns on and off at the correct times to maintain proper engine temperature.

Key specifications include switching temperature range, thread size, connector type, number of pins, and compatibility with the vehicle. It must operate accurately under varying temperature conditions.

Replacement is necessary when the switch fails or becomes inaccurate. Common symptoms include the fan not turning on, running continuously, or engine overheating.

Porza offers a fit guarantee option where your vehicle details are checked against product specifications to ensure correct compatibility.

Porza provides high-quality cooling system components with fast delivery across Europe and options for online ordering or in-store pickup.

If the fit guarantee is selected, compatibility is verified before shipping. If the product does not fit, it can be returned according to the return policy.
