Introduction to power steering reservoir 0004600183
The power steering reservoir 0004600183 is a high-precision hydraulic system component designed for Mercedes-Benz CLS55, C320, ML350, CL500 and other models. As the core fluid storage device of the power steering system, it is manufactured using German original technical standards and molded through precision injection molding to ensure seamless connection with the original Mercedes-Benz vehicle pipeline system.
Functions of power steering reservoir 0004600183
Hydraulic oil storage and circulation
The capacity design accurately matches the requirements of Mercedes-Benz models (standard capacity 0.75L±5%), optimizes the layout of the storage space, and avoids oil overflow when the vehicle is bumpy. The internal guide groove design of the pot body can reduce bubble generation and maintain the hydraulic stability of the steering system.
Multi-stage filtration protection
Equipped with 80μm stainless steel primary filter and 25μm secondary nylon filter element, the double filtration system can intercept 99.3% of metal wear particles and extend the service life of the steering pump and gear components.
Pressure balance control
Integrated dynamic pressure regulating valve automatically compensates for hydraulic fluctuations under sharp steering conditions (response time < 0.2 seconds) to prevent the steering gear from “floating” or “stuck”.
Visual fluid level monitoring
The transparent observation window adopts anti-fogging treatment technology, with two-color scale mark (cold/hot liquid level partition display), supports quick visual inspection of oil status, and the error range is controlled within ±3mm.
Advantages
Original factory compatibility
- The power steering reservoir interface adopts Mercedes-Benz patented quick-release buckle design (tolerance ±0.15mm), supporting tool-free disassembly and assembly
- The sealing ring uses HNBR hydrogenated nitrile rubber, which increases oil resistance by 40% and eliminates interface leakage
- Verified by Mercedes-Benz WIS system data, perfectly adapted to ESP electronic power steering program
Long-lasting and durable design
- Anti-UV coating treatment delays aging of plastic parts (laboratory simulation of 5 years of exposure without embrittlement)
- The bottom shock-absorbing bracket adopts glass fiber reinforced structure with impact strength of 120J/m
- Supports fully synthetic PSF-IV and above steering oil specifications, compatible with Dexron III/MB 345.0 standards
Maintenance cost optimization
- The filter is modularly designed and supports separate replacement (saving 60% of the cost compared to assembly replacement)
- A reserved diagnostic interface can read oil pressure data through the XENTRY diagnostic system
- The maintenance cycle is extended to 80,000 kilometers/4 years (1.5 times the original factory recommended cycle)

FAQ
Q1: How to determine whether the power steering reservoir needs to be replaced?
- Observe whether the tank body has cracks or deformation (focus on the bottom reinforcement area)
- Check the turbidity of the oil: Normally it is transparent amber, if it is milky white or dark black, it needs to be replaced immediately
- Use the diagnostic instrument to read the steering assist pressure value, and the fluctuation range exceeds ±0.3MPa, indicating that the system is abnormal
Q2: How to deal with abnormal steering noise after installation?
- Check whether the steering fluid reservoir installation angle is offset (tolerance ±2° allowed)
- Confirm that the oil specifications used meet the MB 345.0 standard (wrong oil will cause air blockage)
- Check the possibility of air intake in the steering system: apply soapy water to the high-pressure pipe joint to detect bubbles
Q3: Can it be mixed with other brands of oil tanks?
- Mixed installation is strictly prohibited! The working pressure of the Mercedes-Benz steering system reaches 120bar, and non-original products have the risk of bursting
- Third-party products may trigger ESP/ABC system fault codes (such as C1527 hydraulic pressure abnormality)
Q4: What product warranty and after-sales support does your company have?
As a professional power steering reservoir manufacturer, we：
- Provide 18 months of quality assurance (free replacement for non-human damage)
- Support VIN code accurate query adaptability (visit the official website online verification system)
- German TÜV certification laboratory issues material test report (provided with the goods)
