Q: How does the fan clutch differentiate between engine heat and hot ambient air temperature?
A: It doesn't, directly—and it doesn't need to. Its sole job is to keep the engine coolant at the correct temperature, regardless of the cause.
The bi-metallic spring reacts to the temperature of the air passing through the radiator.
If the air is hot because it's a 100°F (38°C) day, the radiator is less efficient, so the coolant stays hotter, which heats the air coming out of the radiator. The spring sees this hot air and engages the fan to compensate.
If the air is hot because the engine is working hard, the same thing happens.
It's a brilliantly simple feedback loop that responds to the actual cooling need of the system.

Q: Could a faulty coolant temperature sensor mimic the symptoms of a bad fan clutch?
A: Yes, absolutely. This is a great diagnostic insight. A faulty Coolant Temperature Sensor (CTS) that sends a falsely "cold" signal to the engine computer (ECU) can prevent the ECU from triggering the cooling fans (on electric fan systems) or, on some modern vehicles, can even affect the control of a solenoid-controlled fan clutch. Always verify actual coolant temperature with a reliable OBD2 scanner and data stream before condemning a mechanical fan clutch. Rule out electronic issues first.

Q: What should be noted when using a fan clutch in winter?
A: Using a fan clutch in winter requires specific attention to adapt to low-temperature conditions and prevent performance issues. For silicone oil fan clutches, low temperatures can increase the viscosity of the silicone oil, making it flow more slowly. This may cause a delay in the fan’s speed adjustment when the engine starts—so it’s recommended to let the engine idle for 2-3 minutes after starting to warm up the oil slightly, ensuring the clutch can respond normally. For electronic fan clutches, low temperatures may affect the accuracy of the temperature sensor (e.g., sensor signals may be delayed or inaccurate), leading the ECU to misjudge the engine temperature and adjust the fan speed incorrectly. Thus, it’s advisable to have the sensor’s functionality checked before winter to ensure it works properly in cold weather. Additionally, snow, ice, or frost often accumulates on the fan blades in winter—this adds extra weight to the blades, causing unbalanced rotation, increased noise, and extra load on the clutch. After snowfall or freezing weather, always clean the snow and ice from the fan blades before starting the engine. Finally, check the clutch’s seals and gaskets—winter cold can make rubber components brittle, increasing the risk of oil leakage; replace any cracked or hardened seals promptly to avoid clutch failure.
