Check the Basics (Fuses & Relays) ​The first step is always the engine room fuse box. ​Main Fuse: Look for the C/FAN 40A fuse. If this is blown, the fan won't work at all. ​High-Speed Relay: Swap the "Fan Hi" relay with a known good relay of the same type (like the Horn relay) to see if the fan engages. If it works with the swap, you just need a new relay. ​2. Test the Fan Resistor ​The fan resistor controls the speeds. It is usually mounted directly on the radiator fan shroud because it needs the airflow to stay cool. ​Visual Check: Inspect the connector for melting or corrosion. This is a common failure point on Kias. ​Continuity Test: Use a multimeter to check for continuity across the resistor pins. If the circuit is "open," the high speed will never engage. ​3. Test the Fan Motor Directly ​To rule out a dead motor: ​Disconnect the fan's electrical pigtail. ​Using jumper wires, connect the fan motor directly to the battery. ​Caution: Keep fingers and tools clear; if the motor is good, it will spin up immediately at full speed. ​If it doesn't spin when connected directly to 12V, the motor is burnt out and the entire fan assembly needs replacement. ​4. Coolant Temperature Sensor (ECT) ​If the fan works when you turn on the Air Conditioning (most cars trigger the fan when the A/C is on) but not when the engine gets hot, the Coolant Temperature Sensor might be sending the wrong signal to the ECU. ​If the sensor fails, the ECU doesn't "know" the engine is hot enough to trigger the high-speed mode. 0:00 Intro 1:15 What About Engine OverHeating 2:45 Tools You'll Need To Diagnose 3:30 Step By Step Troubleshooting 5:15 Common Mistakes to Avoid 6:30 How To Test Engine Fan 9:40 Finally Find Diagnose Fault Engine OverHeat Please Subscribe My YouTube Channel Mughal Auto Electrician For Better Future & Life 💕    / @mughalautoelectrician   My What'sApp Number Mughal Auto Electrician 00968 94775794 #mughalautoelectrician #engineoverheating #autoelectrician #mechanic #throttlebody #r134a
