Vemo V15-99-2006 Temperature Switch, Radiator Fan

The Vemo V15-99-2006 is a precision-engineered temperature switch designed to control the operation of a vehicle’s radiator fan. It serves as an essential component in maintaining optimal engine temperatures by activating or deactivating the fan based on thermal thresholds.

Core Functionality

This device operates as a thermocontact, a type of temperature-sensitive switch that closes or opens its circuit when the surrounding temperature reaches predefined limits. In automotive applications, it is typically mounted near the radiator fan assembly and wired into the vehicle’s cooling system control module.

• Activation Thresholds: The switch is calibrated to trigger at specific temperatures—commonly around 95 °C for activation and 85 °C for deactivation. These values can vary slightly depending on the vehicle model and manufacturer specifications.
• Three-Poles Design: The V15-99-2006 features a three-pole configuration, allowing it to manage both power supply and signal communication simultaneously. This design ensures reliable fan operation without compromising electrical integrity.
• Compact M22x1.5 Threading: With a standard M22×1.5 screw thread, the switch fits seamlessly into most automotive chassis mounting points designed for radiator fan controls.

Compatibility Across Vehicle Brands

The Vemo V15-99-2006 is engineered to be universally compatible with a wide range of European car manufacturers. Its adaptability makes it a popular choice for:

• Audi: Models such as the A1, A3, TT, and various generation Golf and Polo vehicles.
• Volkswagen: Including the Golf IV, Bora, Polo, Touran, and newer models like the Up! and Fox.
• Seat: Models ranging from the Leon and Ibiza III to the Altea and A3.
• Skoda: From the Fabia I and Octavia I to the Rapid and Superb series.

Its universal design ensures that it can be installed in any vehicle where a standard radiator fan temperature switch is required, making it an ideal replacement for OEM parts across multiple brands.

Installation Overview

1. Locate the Existing Switch: Identify the current temperature switch on the radiator fan assembly. It typically resides near the fan housing and is connected to both the power supply and the vehicle’s cooling control module.
2. Disconnect Power: For safety, disconnect the battery or remove the relevant fuses before proceeding with any electrical work.
3. Remove Old Switch: Unscrew the mounting bolts (M22×1.5) and carefully detach the wiring harnesses from the old switch terminals.
4. Mount the V15-99-2006: Align the new switch with the mounting holes, secure it using the provided screws, and ensure a snug fit to prevent vibration damage.
5. Reconnect Wiring: Attach the wiring harnesses to the corresponding terminals on the Vemo switch. Verify correct polarity and connection integrity.
6. Test Functionality: Reconnect power, start the engine, and monitor the fan operation. The fan should engage when the coolant temperature rises above the activation threshold and disengage once it cools below the deactivation point.

Key Technical Specifications

Reliability and Durability

The Vemo V15-99-2006 is built with robust materials that withstand the harsh automotive environment. Its plastic housing resists corrosion, while the metal contacts are engineered to maintain low resistance even after prolonged use. The switch’s design includes a protective seal against coolant spray and mechanical shock, ensuring long-term reliability.

Maintenance Tips

• Regular Inspection: Periodically check the wiring connections for corrosion or loose contacts. Tighten any loose screws to prevent intermittent operation.
• Clean Surroundings: Keep the area around the switch free from debris and coolant residue, which can affect thermal conduction.
• Functional Testing: During routine service intervals, verify that the fan activates at the correct temperature by monitoring engine coolant readings.

Conclusion

The Vemo V15-99-2006 Temperature Switch, Radiator Fan is a versatile, high-quality component essential for maintaining vehicle cooling system efficiency. Its universal compatibility across major European automotive brands, precise temperature control, and durable construction make it an indispensable part for mechanics and car owners alike who seek reliable fan operation and optimal engine performance.
