Please confirm your Opel model and year match this description before . Compatibility and fit Designed for Opel models Astra Zafira and Vectra, year 2006 Radiator Fan Motor Resistor with OEM part numbers 3134503108 and 94749639 This is a direct replacement compatible with the specified vehicles What it does The resistor provides resistance in the circuit to create a voltage drop that limits the current flowing to the radiator fan motor By controlling current, it helps regulate the fan operation and protect electrical components Heat management and reliability The resistor is designed to dissipate heat to maintain stable performance during operation Proper heat dissipation helps prevent overheating and ensures continued smooth running of the radiator fan Why you need it Restores or maintains correct radiator fan function, especially for low speed operation Replaces a worn or failed resistor to protect the vehicle's cooling system and electrical wiring Key attributes Function: current limiting and voltage drop to control radiator fan speed Compatibility: Opel Astra Zafira Vectra 2006 with OEM numbers 3134503108 or 94749639 Performance: supports reliable radiator cooling by ensuring proper fan operation Use scenarios Scenario 1: Replacing a faulty radiator fan resistor on a 2006 Opel Astra to restore normal lowspeed cooling when the fan would not run correctly at low speeds Scenario 2: Restoring radiator cooling in Opel Zafira or Vectra models that use the same resistor part numbers, ensuring consistent fan performance Scenario 3: Routine maintenance in hot climates or during heavy traffic where dependable radiator fan operation is critical to prevent engine overheating Notes Please verify your exact model and year match Opel Astra Zafira Vectra 2006 and the included part numbers 3134503108 or 94749639 before This description reflects the original brand, specifications, models, and intended function without adding features or specifications
