Common Issues with CS55 Engine?
2 Answers
Here is an introduction to the common issues with the CS55 engine: 1. Abnormal vibration: There are many reasons that can cause abnormal engine vibration, the most common being idle vibration due to dirty throttle bodies. Other causes include poor spark plug performance, damaged ignition coils, and mechanical engine failures. 2. Severe engine carbon buildup: The main reason for severe engine carbon buildup is the use of low-quality engine oil and fuel. 3. Engine oil leakage: Engine oil leaks can be divided into visible and hidden types. Visible leaks are those we can see externally, such as valve cover leaks, oil pan leaks, crankshaft front seal leaks, oil filter leaks, etc. Hidden leaks are not visible from the outside, such as valve stem seal leaks and crankshaft rear seal leaks.
I've owned my Changan CS55 for over three years now, and there's always been some abnormal noise during cold starts, like a metallic knocking sound. I've talked with other CS55 owners, and many have encountered similar issues. It's probably caused by a loose timing chain or turbo components. Additionally, fuel consumption is slightly high, reaching up to 10 liters per 100 km in city driving, though it's better on long trips. In terms of power, the acceleration is a bit sluggish at start-up, but it performs decently at high speeds. I recommend regular oil changes and checking for carbon buildup every 5,000 km. Warming up the engine for half a minute during cold starts can help reduce the noise. These minor issues don't affect safety, but it's better to detect and fix them early to avoid bigger problems. Overall, the car offers good value for money with affordable maintenance costs, so there's no need to worry too much.
