21524001 22767073 Crankcase Ventilation Oil Separator Fit D13 Euro5 Engine Heavy Duty Truck Aftermarket Replacement Part

OE numbers 21524001 and 22767073 Crankcase Ventilation Oil Separator is exclusively built for heavy-duty trucks fitted with D13 Euro5 engines, incompatible with Euro4 or Euro6 engine variants.

Manufactured following strict OEM specifications, the built-in multi-stage coalescing filter efficiently separates oil mist from crankcase blow-by gas. It cuts excessive oil consumption, prevents turbocharger contamination and extends overall engine service life. All connection ports, mounting brackets and sealing surfaces match factory original units to support direct bolt-on installation without trimming or adjustments.

The high-temperature resistant housing and wear-resistant filter core withstand severe long-haul driving conditions. It serves as a perfect replacement for clogged, leaking or defective original separators during engine maintenance. Confirm your engine emission standard and model with sales before ordering.
