This Diesel Exhaust Fluid (DEF) Tank Cap, marked with part numbers G87HE000047 and K08-1205246-02, is exclusively engineered for Yuchai diesel engines. It adheres to the original equipment (OE) dimensions and mounting standards of Yuchai’s DEF storage systems, ensuring a seamless fit with the DEF tank neck. The precise sizing eliminates cross-threading risks during installation and guarantees alignment with Yuchai’s engine assembly, making it a direct replacement part for worn or damaged original caps without the need for modifications

PRODUCT DESCRIPTION
Chemical-Resistant Material – Durability Against Urea-Based DEF
Constructed from high-grade, urea-resistant polymers, the Yuchai DEF Tank Cap (G87HE000047/K08-1205246-02) withstands long-term exposure to DEF’s corrosive properties. Unlike generic caps that may become brittle or crack due to chemical degradation, this component maintains structural integrity over time, preventing fluid leakage and material contamination of the DEF. The material also resists swelling or warping under extreme under-hood temperatures (ranging from -40°C to 80°C), ensuring consistent performance in harsh operating environments
Airtight & Liquid-Tight Sealing – Preserving DEF Purity
Equipped with a dual-layer silicone sealing gasket, this DEF Tank Cap creates an airtight and liquid-tight barrier when fastened. It effectively blocks the ingress of dust, moisture, and debris into the DEF tank, which could otherwise clog the SCR (Selective Catalytic Reduction) system or degrade DEF quality. Additionally, the seal prevents DEF evaporation – a critical feature that maintains fluid concentration (32.5% urea, the industry standard) and avoids inaccurate DEF level readings in Yuchai’s engine management system
Pressure Equalization Vent – Protecting Tank Integrity
The G87HE000047/K08-1205246-02 DEF Tank Cap integrates a precision venting mechanism to balance pressure inside the DEF tank. As DEF is consumed during engine operation or expands/contracts due to temperature changes, the vent releases excess pressure or allows air intake, preventing tank deformation, cracks, or impaired fluid flow. This design also ensures smooth DEF dispensing during refueling, eliminating slow or interrupted filling caused by vacuum buildup
Compliance with Emission Standards – Supporting Regulatory Compliance
This Yuchai DEF Tank Cap is manufactured to meet global emission regulations (such as Euro V, China VI, and EPA Tier 4) and Yuchai’s internal quality benchmarks. By maintaining the integrity of the DEF system, it indirectly supports the SCR system’s ability to reduce nitrogen oxide (NOx) emissions – a key requirement for diesel engines to comply with environmental laws. The cap’s traceable part numbers (G87HE000047/K08-1205246-02) also ensure full accountability for maintenance records, simplifying compliance audits for fleet operators
TECHNICAL SUPPORT
1. Accessories selection consultation
- Provide ** intelligent selection tools ** (such as parts matching query system), input the vehicle model VIN code or engine model to match the corresponding parts number, reducing the selection error rate.
The technical team is available online 7×12 hours to answer technical questions about accessories (such as material compatibility and installation processes).
2. Customized development support
We offer specialized R&D services for special market demands (such as heat dissipation accessories for high-temperature regions in the Middle East and dedicated suspension components for road conditions in Africa), and complete sample delivery within six weeks.
3. Training and Technical materials
Provide remote/on-site training for the customer's after-sales team (such as diagnosis of electrical control accessories and DPF regeneration operation), along with multilingual versions of the "Accessories Installation Manual" and "Troubleshooting Guide".
4. Quality Traceability and Improvement
Through the QR code traceability system (one product, one code), track the production batch of accessories and the source of raw materials, respond quickly to quality complaints and initiate improvement processes.
AFTER-SALES AND LOGISTICS SUPPORT
After-sales service
Quality Assurance Policy
-The warranty period for original factory parts is 12 months (counting from the date of signature for receipt), covering material defects, process issues, and man-made damage.
- Provide "Localized Express repair Service" : Cooperate with third-party repair networks in markets such as Southeast Asia and the Middle East, and deliver emergency parts to designated repair points within 4 hours.
Return and Exchange Process
-The customer is required to submit the test report (such as a third-party appraisal) within the warranty period. After confirmation by Dongfeng, a reissue or refund will be arranged within 5 working days.
Logistics support
Warehouse Layout
-Five major regional accessory centers have been established globally (Southeast Asia, the Middle East, Africa, South America, and Europe) to achieve "next-day delivery" for mainstream accessories (covering customers within the regions).
Emergency Logistics Plan
-Emergency parts can be directly delivered within 48 hours via the "Dongfeng Exclusive Aviation Special Line" (such as engine ECU, brake valves and other key components).
Packaging Optimization
-Use shockproof and moisture-proof packaging (such as honeycomb cartons + pearl cotton), and reinforce fragile parts (such as glass, sensors), keeping the damage rate within 0.5%.
