FAQ

Q1: What truck models and fan clutch types do you supply?
A: We export truck fan clutches for ISUZU, JMC (Jiangling), Qingling, JAC (Jianghuai), Foton, and other major Chinese truck brands.

Q2: What are the symptoms of a bad fan clutch on a truck?
A: The most common signs of a failing fan clutch include: engine overheating at idle or under heavy load (especially in traffic), a constant loud fan roar that never disengages even on the highway, silicone fluid leaking (oily residue around the bearing or thermal spring), loose fan blades with excessive play, poor A/C performance, and reduced fuel economy. If the fan spins freely by hand when the engine is hot, or cannot be turned at all when cold, the clutch has failed internally.

Q3: How do I test whether my truck’s fan clutch is working properly?
A: The most reliable method is using an infrared tachometer to compare fan speed against water pump shaft speed. A properly engaged fan clutch should read approximately 80–90% of shaft speed; a disengaged clutch should read 20–30%. You can also perform a cold-engine check: right after startup, the fan should roar briefly for 1–2 minutes, then quiet down as the silicone fluid redistributes. If the roar never stops, the clutch is locked up; if the fan never engages even when the engine is fully warmed up, the clutch has slipped or leaked.

Q4: Are your fan clutches OEM quality, and should I replace the fan clutch together with the water pump?
A: We offer both genuine OEM and premium aftermarket fan clutches. Our aftermarket units use high-grade silicone fluid, sealed bearings, and calibrated bimetallic springs to match OE engagement temperatures and service life. Since the fan clutch is typically mounted on the water pump shaft, many fleet mechanics choose to replace both components together — a failed water pump bearing will quickly destroy a new fan clutch, and vice versa. We supply both parts as a matched set for convenient fleet maintenance.
