Electronic Controlled Silicone Fan Clutch Assembly OE 1308065-XLTF490 for Dongfeng GX & KX Heavy Trucks

This OE 1308065-XLTF490 silicone fan clutch adopts electronic ECU closed-loop control logic, the built-in electromagnetic valve automatically adjusts silicone oil filling amount according to engine coolant temperature feedback, so the fan only runs at high speed when cooling demand is high, and separates at low temperature to reduce engine extra load and fuel consumption. The whole aluminum housing is equipped with dozens of radial radiating fins, greatly expanding heat exchange area to quickly take away heat generated by internal viscous friction, effectively avoiding silicone oil failure and clutch locking under long climbing high-load conditions. The internal cavity uses multi-layer composite rubber sealing gaskets at all rotating joints, completely blocking silicone oil seepage to prevent fan speed loss and cooling failure. The rear mounting flange adopts CNC precise hole position machining, perfectly matching Dongfeng GX & KX water pump shaft size without gaskets modification during replacement. The matched waterproof wiring plug avoids circuit short circuit caused by engine compartment mud and water splashing.

Heavy truck engine maintenance technicians often face many cooling system failures caused by inferior mechanical fan clutches: purely mechanical temperature sensing clutches cannot adjust speed intelligently, the fan keeps running at full speed in cold weather, increasing fuel consumption and cab wind noise; thin small-fin heat sink cannot dissipate heat effectively under heavy load, silicone oil deteriorates quickly leading to fan locking and engine overheating; low-grade single-layer sealing rings leak viscous oil easily, resulting in insufficient fan torque and high water temperature alarm. This genuine DFCV OEM electronic silicone fan clutch completely eliminates these hidden troubles: ECU intelligent variable speed saves fuel; large multi-fin aluminum shell prevents overheat; multi-ring full seal stops oil leakage, cutting engine overheat overhaul frequency and extra fuel cost for Dongfeng GX & KX fleets.

As a core intelligent cooling spare part of Dongfeng GX & KX heavy truck diesel engine system, this electronic silicone fan clutch fully complies with Dongfeng Commercial Vehicle official heavy-duty engine cooling component production quality standards. Every finished fan clutch completes three mandatory professional durability laboratory tests: 800-hour continuous high-temperature load aging test, long-term silicone oil sealing soaking anti-leakage test, 100,000 times speed switching fatigue cycle test, maintaining stable viscous transmission and electronic control performance under summer high-temperature plateau climbing, northern cold winter start and dusty construction site transportation environments. Anti-counterfeit QR code label and laser engraved OE serial number are printed on aluminum housing and original carton for genuine product traceability, all flange mounting hole spacing, wiring plug pin definition and silicone oil torque parameters strictly follow original vehicle factory engineering drawings, zero assembly mismatch after replacement for all Dongfeng GX and KX heavy truck models.

We are authorized Dongfeng  wholesale supplier of genuine DFCV OEM engine cooling spare parts for Dongfeng GX & KX heavy trucks, maintaining permanent sufficient stock of OE 1308065-XLTF490 electronic silicone fan clutch assemblies. Each whole clutch unit is wrapped with thick shockproof bubble film and reinforced hard carton packaging to prevent aluminum fin extrusion deformation and internal sealing ring damage during cross-border sea and land logistics transit. Its pre-calibrated mounting flange and matching waterproof wiring plug allow professional heavy truck maintenance technicians to finish full fan clutch replacement within 22 minutes without refitting water pump fixed supports or custom wiring adapters, drastically cutting vehicle downtime for long-haul logistics fleets and truck engine overheat fault repair garages. We provide a 24-month silicone oil anti-leakage and stable electronic speed regulation quality warranty plus free remote water pump shaft mounting matching installation guidance for all worldwide bulk wholesale buyers.
