Bellam Silicone Oil Fan Clutch 1313010-DV404H ECU PWM Cooling Fan Clutch for Heavy Duty Truck Cooling System

The Bellam silicone oil fan clutch (part number 1313010-DV404H) is a replacement component for the air brake and air suspension systems of heavy-duty trucks, buses and semi-trailers. It is built to original equipment specification from quality materials, so it installs on the original mounting points and performs reliably throughout the service life of the vehicle. Key ratings include original equipment ratings.

ECU PWM control adjusts fan speed in real time, holding engine temperature steady while a built-in Hall sensor feeds back accurate speed signals to avoid fault alarms. At low temperature the fan disengages to cut engine load, save fuel and reduce noise, and the unit works from -40°C to 120°C.

Every unit is manufactured to original equipment specification and inspected before it leaves the factory, so it matches the fit, function and durability of the original part. Sealed, vibration-tested construction keeps performance stable in the heat, dust, road salt and constant vibration found on commercial vehicles, and standard interfaces make installation and maintenance straightforward. Spare parts, technical data and fitting advice are available on request.
