Volkswagen coolant should be replaced every two years or 40,000 kilometers. Methods to determine when to replace coolant: 1. Check the coolant's instructions for use. Generally, coolant added to the radiator has a service life of two years. Not replacing the coolant for a long time will reduce the anti-rust quality inside the radiator, leading to damage to the radiator, pipes, etc. It will also affect the boiling and freezing point parameters, impairing cooling efficiency and causing harm to the engine. 2. Open the radiator and inspect the turbidity of the liquid inside. If it appears very cloudy and contains floating particles from corroded metal parts of the radiator, replacement is recommended.

How to Deal with Carbon Monoxide Exhaust?

There are three methods to deal with carbon monoxide exhaust: 1. Clean the three-way catalytic converter: Use a drip bottle to inject cleaning solution into the vacuum tube of a running engine, similar to an IV drip. The solution burns off carbon deposits in the combustion chamber, enhancing engine power. It then cleans the contaminated three-way catalytic converter in the exhaust pipe, restoring its original function of energy saving and emission reduction. 2. Spray nano-precious metal platinum-rhodium-palladium liquid into the aged three-way catalytic converter: If the rare metals platinum, rhodium, and palladium inside have deteriorated and cleaning fails to restore the exhaust purification effect, spraying nano-precious metal platinum-rhodium-palladium liquid into the removed three-way catalytic converter can effectively treat carbon monoxide exhaust. 3. Use a Fire Lotus three-way catalytic metal soft carrier: If the three-way catalytic converter is empty, insert the Fire Lotus three-way catalytic metal soft carrier into the exhaust pipe to act as the original converter's carrier, purifying carbon monoxide exhaust.

How to Tighten a Loose Steering Wheel?

Steering wheel too loose adjustment steps are as follows: 1. First, check if there is any gap in the steering ball joint, and tighten the ball joint screw slightly. 2. If there is no gap, then adjust the steering gear. 3. If it still doesn't work, it may be that the steering system is broken. It is best to go to a repair shop for professional inspection and repair by a mechanic. The following are possible causes of a loose steering wheel: (1) Severe wear of the steering gear and tie rod ball joint, the steering universal joint wear produces a gap, there is a gear-shaped shaft where the steering wheel horn is pressed, it is estimated that the teeth on the gear-shaped shaft are worn off. (2) The steering gear is without power assistance, the actual failure caused by damage to the steering system.

Does the Transmission Filter Need to Be Replaced?

The transmission filter needs to be replaced, typically when the transmission fluid is changed. Common types of automatic transmission filters include those for dual-clutch transmissions (DCT), automatic transmissions (AT), and continuously variable transmissions (CVT). Here is a brief introduction to the three types of transmissions: (1) Dual-clutch transmissions (DCT) are currently very popular due to their fast gear-shifting speed and high transmission efficiency. The structure of a DCT is similar to that of a manual transmission, but it features two sets of clutches—one for odd-numbered gears and the other for even-numbered gears. (2) Automatic transmissions (AT) are the most widely used, technologically mature, and have the highest production and R&D costs. They offer excellent gear-shifting smoothness and durability. (3) Continuously variable transmissions (CVT) have a simple structure, compact size, and lightweight design. Their production cost is relatively low, making them a common choice for many affordable family cars.

Is a Roof Rack Illegal?

Installing a roof rack on a car is not illegal, but it depends on the situation. Here are the details: 1. For passenger vehicles, the height of cargo loaded on the roof rack must not exceed 0.5 meters from the roof or 4 meters from the ground. 2. If either of these limits is exceeded, the vehicle may be stopped by traffic police. Therefore, before purchasing a roof rack, you should measure the space to ensure compliance. Here are some considerations regarding whether to install a roof rack: (1) If you frequently need the functionality, such as for outdoor trips, road trips, or traveling home for holidays, installing a roof rack can significantly increase your vehicle's carrying capacity. (2) If your vehicle is primarily used for daily commuting within the city and you don’t find a roof rack particularly appealing, you may not need to install one. Additionally, roof racks require crossbars, which not only add weight and increase fuel consumption but also create some wind noise while driving.
