Q: How to check for silicone fluid leakage in a fan clutch?
A: Several methods can check for fluid leakage. Visual inspection: check clutch housing surface for oil stains, especially at shaft seals and joint seams. Dust accumulation: leaked fluid attracts dust, forming obvious sludge traces. Performance testing: if clutch engagement is weak or completely failed without external abnormalities, internal leakage may be suspected. Weight comparison: significant weight difference between new and old parts may indicate fluid loss. However, professional disassembly inspection is most reliable, though replacement of the entire assembly is usually recommended over repair.

Q: How should a fan clutch operate during high-speed driving?
A: During high-speed driving (usually above 70-80 km/h), due to strong ram air effect, sufficient airflow passes through the radiator front surface, meeting cooling needs even under high engine load. At this time, the fan clutch should be disengaged or in low coupling state with reduced fan speed. This reduces unnecessary power consumption and noise, following energy optimization principles. If the fan continues running at full speed during highway driving, it may indicate a permanently engaged clutch fault.

Q: What impact does wear on the "drive belt" pulley groove of a truck fan clutch have?
A: Worn pulley grooves cause belt slipping (insufficient fan speed), uneven belt wear (shortened service life), and abnormal noise (friction vibration). Replace the worn pulley and use it with a new belt to avoid cooling failures caused by pulley groove issues. A smooth, intact pulley groove ensures effective power transmission between the belt and clutch.
