Pourquoi le ventilateur de voiture reste en marche et ne s’arrête pas ? | SIMOAUTO

Why does my car's cooling fan stay on and won't stop? Does the radiator fan run constantly, even when the engine is cold or after you've turned off the ignition? In this video, I'll explain the most common causes and how to perform a simple diagnosis before replacing parts unnecessarily. We'll look at: ✔️ Faulty temperature sensor ✔️ Stuck fan relay ✔️ Engine control unit (ECU) fault ✔️ Air conditioning system ✔️ Engine limp mode 🎯 Goal: to understand the source of the problem and avoid engine overheating or costly repairs. 👉 A fan that stays on isn't always a serious problem, but it's important to check it quickly. #EngineFan #Cooling #Overheating #SIMOAUTO
