The TFS138 fan switch plays a critical role in regulating the temperature of the engine. It monitors the coolant temperature and, when the temperature rises to a certain threshold, it sends a signal to activate the radiator fan. This helps in cooling the engine by dissipating heat from the radiator.

Key Features:

• Temperature Sensing: Fan switches like TFS138 are designed to be temperature-sensitive. They activate the radiator fan when the coolant temperature reaches a predetermined level, and they deactivate it when the temperature decreases below that threshold.
• Compatibility: Automotive components like the TFS138 are typically designed to be compatible with specific vehicle makes and models. It's essential to ensure that this fan switch matches the requirements of your vehicle's cooling system. Refer to the Tridon Part Finder or consult your vehicle's manual to select the correct part number.
• Tridon Brand: Tridon is a reputable manufacturer known for producing automotive components, including fan switches. Their products are designed to meet the demands of various vehicle applications.
• Installation: Proper installation of the fan switch is crucial for its correct operation. The switch is typically installed in the cooling system, often near the radiator, and is connected to the electrical circuit that controls the radiator fan.
• Maintenance: Fan switches do not require regular maintenance but should be checked if you experience issues with engine overheating or coolant temperature warnings.
• Cooling System Control: The operation of the radiator fan is vital for controlling engine temperature and preventing overheating. Fan switches are an integral part of the cooling system's control mechanism.
• Safety: Overheating can cause engine damage and reduce vehicle performance. Fan switches help prevent overheating and ensure the engine operates within a safe temperature range.

Please note that specific details about the temperature threshold and compatibility of the TFS138 may vary based on the manufacturer's specifications and the intended vehicle models. To ensure the correct operation of your vehicle's cooling system, consult the Tridon Part Finder or contact a certified mechanic or parts specialist to select the right fan switch for your specific automotive needs.
