Detailed Fluid Specifications

Engine Oil

The Changan CS55 requires high-quality synthetic engine oil to protect its turbocharged engines. Always use the recommended viscosity grade and API classification for your specific model year and engine.

First Generation (2017-2021)

• 1.5L Turbo: 5W-30, API SN or higher
• 2.0L Turbo: 0W-40, API SN PLUS or higher

Second Generation (2021-Present)

• 1.5L Turbo: 0W-30, API SP or higher

It’s crucial to maintain the correct oil level and change the oil and filter at the recommended intervals to ensure optimal engine performance and longevity.

Transmission Fluid

Proper transmission fluid is essential for smooth gear shifts and protecting transmission components from wear.

Manual Transmission

The 6-speed manual transmission used in first-generation CS55 models does not require regular fluid changes under normal operating conditions. However, it’s recommended to check the fluid level and condition during routine maintenance.

Automatic Transmission

First-generation CS55 models equipped with the 6-speed automatic transmission use ATF AW-1 fluid. This specialized fluid is designed to provide excellent protection and shift quality for Aisin Warner transmissions.

Dual-Clutch Transmission (DCT)

The 7-speed DCT used in second-generation CS55 Plus II models requires a specific Changan DCT fluid. This fluid is formulated to meet the unique demands of dual-clutch transmissions, ensuring smooth operation and long-term reliability.

Coolant

Changan recommends using an ethylene glycol-based coolant for all CS55 models. The coolant protects the engine from freezing in cold temperatures and prevents corrosion within the cooling system.

• Coolant Capacity: 7.5L
• Type: Ethylene glycol-based, meeting Changan specifications

Always use a 50/50 mixture of coolant and distilled water to achieve the optimal balance of freeze protection and heat transfer properties.

Brake Fluid

All Changan CS55 models use DOT 4 brake fluid. This high-performance fluid has a high boiling point to maintain braking effectiveness under demanding conditions.

• Capacity: 0.8L
• Type: DOT 4

Brake fluid is hygroscopic, meaning it absorbs moisture from the air over time. This can lower its boiling point and compromise braking performance. Regular replacement every 2 years or 40,000 km is essential for safety.

Power Steering Fluid

CS55 models equipped with hydraulic power steering use ATF III fluid. This multi-purpose fluid provides smooth steering operation and protects power steering components from wear.

• Capacity: 1.0L
• Type: ATF III

Note that some newer CS55 models may use electric power steering, which does not require fluid.

Windshield Washer Fluid

The windshield washer reservoir has a capacity of 4.0L. Use a high-quality washer fluid appropriate for your climate to ensure clear visibility in all conditions.

Maintenance Tips for Changan CS55 Owners

1. Follow the recommended maintenance schedule in your owner’s manual.
2. Use only high-quality fluids that meet Changan specifications.
3. Check fluid levels regularly, especially before long trips.
4. Address any leaks or unusual fluid consumption promptly.
5. Keep records of all fluid changes and maintenance performed.
6. Consider more frequent fluid changes if operating in severe conditions (extreme temperatures, dusty environments, frequent short trips).
7. Have your CS55 serviced by qualified technicians familiar with Changan vehicles.

Conclusion

Proper fluid maintenance is crucial for the performance, reliability, and longevity of your Changan CS55. By using the correct fluids and following the recommended maintenance intervals, you can ensure your CS55 continues to provide dependable transportation for years to come.

Always consult your owner’s manual or a Changan dealer for the most up-to-date and model-specific fluid recommendations, as specifications may vary slightly between production years and markets.
