This OEM VG1500060402 integrated silicone cooling fan assembly is original cooling spare part matched for Sinotruk WD615 and WT615 series engines, widely installed on HOWO heavy-duty trucks and HOKA models. It combines high-strength fan blade and temperature-sensitive silicone fan clutch as one complete unit.
The fan blade adopts high-toughness reinforced nylon material, featuring impact resistance, low deformation and long service life under high-speed rotation. Built-in silicone viscous clutch automatically adjusts fan rotation speed according to coolant temperature: slow rotation at low temperature to cut power loss, full-speed operation at high temperature for efficient heat dissipation, effectively solving engine overheating during heavy load and uphill driving.
Manufactured strictly following OEM size standard (φ640 overall diameter), mounting hole positions and interface fully consistent with original engine, supporting direct bolt-on replacement without modification. All finished fans pass dynamic balance test, high-temperature aging test and vibration test before delivery, stable operation and low failure rate.
It is the perfect replacement for cracked fan blades, failed silicone clutches and overheating faulty original cooling fans, widely supplied to engine overhaul workshops, logistics fleet maintenance stations and global Sinotruk heavy truck cooling spare parts wholesalers. Sufficient spot inventory and competitive factory direct price available.
