Here are the methods to clean willow catkins from the car radiator: 1. For external cleaning, use high-pressure air from an air pump to blow out debris from the gaps instead of washing with water; 2. For internal cleaning, use chemical methods to remove scale. Professional car radiator descaler can be used to clean the inside of the radiator without disassembly; 3. It can also be cleaned while the car is running. Follow the instructions carefully, directly pour the specialized scale remover into the car's water circulation system, let it soak, idle or drive for 20-30 minutes, then drain the descaler from the radiator and the system.

When cleaning willow catkins from the radiator myself, I first use a household water hose set to shower mode to rinse the radiator surface. The water pressure shouldn't be too high, or it may bend the cooling fins. Focus on flushing the gaps and corners of the radiator where catkins tend to accumulate. If the catkins are stubbornly stuck, I gently brush them with a soft-bristled toothbrush, then use compressed air cans to blow along the direction of the fins. Remember to wear goggles during operation as debris can easily fly into your eyes. Check annually after the spring willow catkin season. I also bought a ¥80 stainless steel bug screen from Taobao to block most catkins. For emergency situations, a car vacuum can remove some surface dust, though with limited effectiveness.

Is Paintless Dent Repair Technology Good?

Paintless dent repair technology is better compared to traditional bodywork and painting. Here is some extended information about paintless dent repair: 1. Preserves the original paint: Paintless dent repair technology uses patented techniques and streamlined processes to maximize the preservation of the car's original paint, maintaining the vehicle's original value. Traditional bodywork and painting involve multiple complex steps such as disassembly, bodywork, filling, painting, and baking. Even a small dent on a door would require repainting the entire door to avoid color mismatch. 2. Shorter repair time: Paintless dent repair typically takes about 10 to 60 minutes to fix a dent. Traditional bodywork and painting can take 1 to 2 days, affecting normal vehicle use. 3. Better long-term results: After paintless dent repair, there is no discoloration or fading, keeping the car in its original condition. If the traditional bodywork and painting process is not up to standard, it may cause cracks and fading in the paint.

What is the difference between factory off-line and original factory parts?

The differences between factory off-line and original factory parts are as follows: 1. Quality difference. Factory off-line parts are defective or substandard products with certain flaws; original factory parts are manufactured by the original manufacturer, with quality and appearance identical to the original vehicle, and come with corresponding certification. 2. Price difference. Due to the defects in factory off-line products, which are non-compliant, their prices are generally lower. More information about different types of parts: 1. Genuine parts are qualified components produced by authorized manufacturers. Although they are made by qualified manufacturers, they may not meet the specifications of original factory parts, so there is still a distinction. 2. Pure dismantled parts are automotive components removed from original vehicles. Since it's unclear whether they are from new, used, or accident vehicles, the quality of these parts remains controversial.

Should the new Sylphy use 92 or 95 octane gasoline?

The new Sylphy uses 92 octane gasoline. In terms of power, this car is equipped with a 1.6L naturally aspirated engine. Compared to turbocharged engines, naturally aspirated engines have relatively lower power output, making 92 octane fuel sufficient. Relevant information about gasoline octane ratings is as follows: 1. The gasoline octane rating is the ratio of the actual gasoline's anti-knock performance to that of standard gasoline. The higher the octane rating, the stronger the anti-knock performance. 2. Standard gasoline is composed of isooctane and n-heptane. Higher octane ratings are not necessarily better; the appropriate gasoline octane rating should be selected based on the engine's compression ratio. 3. To evaluate the anti-knock performance of fuel, two methods are generally used: the Motor method and the Research method. The evaluation is usually conducted on a specially designed single-cylinder engine with variable compression ratio.
