The OE: 1111402AED15 fuel filter assembly is the primary fine filtration module for Haval H6 diesel models, supporting the precision needs of modern common-rail injection systems.
It removes fine contaminants and moisture before fuel reaches the high-pressure pump and injectors.
This assembly helps maintain smooth combustion, predictable torque delivery, and stable performance during daily driving and long-distance travel.
Its design supports reliability across diverse climates and varied fuel-quality conditions.
Compatibility
The assembly fits Haval H6 diesel vehicles powered by the following engines:
-
GW4D20 diesel engine
-
GW4D20D upgraded version
-
GW4D20M enhanced variant
These engines rely on clean and stable fuel to maintain accurate injection control.
The filter integrates with the H6’s two-stage diesel filtration system and serves as the final stage before the high-pressure pump.
Its housing and connector geometry follow OE standards for direct and accurate installation.
The assembly performs reliably in export markets where diesel quality may vary.
Filtration / Material / Mechanical Design
The filter uses a multi-layer synthetic medium engineered to capture fine particles while maintaining steady flow.
Its metal housing handles pressure changes and temperature cycles common in diesel operation.
Internal water-separation channels help manage moisture within the system.
OE-grade seals support stable pressure and prevent air intrusion.
The assembly operates effectively in dusty, warm, and high-humidity environments often encountered in H6 markets.
Flow Stability & Engine Protection
Clean fuel supports accurate injector spray patterns and smooth combustion.
This assembly helps maintain reliable cold-start behavior and stable idling.
Consistent filtration reduces strain on the high-pressure pump during heavy load conditions.
By removing fine contaminants, the unit supports long-term reliability and steady performance for the H6 diesel platform.

Maintenance Replacement (Official Interval)
The recommended replacement interval for H6 diesel fine filters is 20,000 km.
A shorter interval of 10,000–15,000 km is advised when operating in regions with inconsistent diesel quality.
Routine inspection for moisture or debris is recommended during scheduled service.
