Dongfeng GX Metering pump assembly 1205710-T69L0

Engineered exclusively for Dongfeng GX models, this assembly matches OEM dimensions with ±0.1mm tolerance, ensuring perfect alignment with the vehicle’s fluid lines and mounting brackets. The inlet/outlet ports (10mm diameter, quick-connect type) fit exactly into the factory hoses (e.g., urea tank lines), creating a leak-tight seal without adapters. The mounting base (4 pre-drilled holes, 6mm diameter) aligns with the vehicle’s frame, eliminating vibration-induced misalignment. The electrical connector (6-pin) is identical to the factory part, plugging directly into Dongfeng GX’s wiring harness—no splicing or voltage adapters needed. Unlike generic pumps, it follows the system’s original layout, avoiding interference with nearby components (e.g., engine hoses, electrical cables). Rigorously tested on Dongfeng GX test vehicles, it passes 180+ fitment checks to guarantee consistency, ensuring hassle-free replacement

Built to endure aggressive fluids like SCR urea (urea solution) or fuel additives, the assembly uses corrosion-resistant materials. The pump’s fluid chamber is made of PPS (polyphenylene sulfide) plastic, which resists chemical degradation from urea, acids, and alkalis—tested to withstand 500 hours of immersion in 32.5% urea solution without cracking or swelling. The piston seal (FKM fluorocarbon rubber) maintains elasticity and sealing performance across -40°C to 120°C, preventing fluid leakage even under thermal stress. The inlet/outlet valves are made of ceramic (alumina), ensuring wear resistance and avoiding metal corrosion that could contaminate fluids. It also passes salt spray testing (500 hours) for external components, ensuring the housing resists rust in high-humidity environments. For owners, this durability means reliable operation for 80,000+ km, reducing maintenance costs

The 1205710-T69L0 assembly is designed for stable performance in harsh automotive environments. It features a vibration-damping mounting bracket (rubber bushings with 60 Shore A hardness) that absorbs 80% of engine vibration (tested to 50–2,000Hz), preventing internal component damage or loosening. The electrical system includes a voltage regulator (9–32V) and surge protector, ensuring stable operation even during battery voltage fluctuations (e.g., cold starts, alternator issues). The pump’s motor uses a brushless design with a copper-wound stator, reducing heat generation and ensuring continuous operation at 100% load for 2 hours without overheating. Tested under extreme conditions (temperature cycling: -40°C to 85°C; vibration: 20g peak), it maintains flow accuracy and no leakage, ensuring uninterrupted fluid delivery for critical systems like SCR

Designed for easy installation, the assembly requires no specialized tools beyond standard wrenches (10mm, 13mm) and a screwdriver. The process takes 30 minutes max: 1) Disconnect the vehicle’s battery and relieve fluid pressure (e.g., clamp urea lines); 2) Unplug the electrical connector and disconnect inlet/outlet hoses using the factory quick-release clips; 3) Remove the 4 mounting screws securing the old pump; 4) Align the new pump with the mounting bracket, secure screws (torque: 8±1 N·m), and reconnect hoses/connector; 5) Reconnect the battery and prime the pump via the vehicle’s ECU (automatic priming function). No system calibration or fluid flushing is needed— the pump operates immediately. A step-by-step instruction manual with diagrams is included, making it accessible to repair shops and DIY owners alike, minimizing vehicle downtime
