How to Deal with Insufficient Car Coolant?

If the coolant level is below the minimum line at normal temperature, you can add coolant. When adding, ensure the level does not exceed the maximum mark, as the coolant expands when hot due to thermal expansion. If the coolant level decreases over two years, there is no need to replace it; you can simply continue to top it up. The added coolant should have the same composition as the existing coolant. Here are some related points: 1. Note: Do not use water as a substitute unless absolutely necessary. In emergencies where coolant is unavailable, you can use soft water, such as purified water. Hard water can form scale at high temperatures, which, like in a household kettle, can clog the water jacket over time. 2. Coolant: Coolant consists of water, antifreeze, and additives. Based on the antifreeze component, it can be classified into types such as alcohol-based, glycerol-based, and ethylene glycol-based coolants.

Where is the air conditioning drain outlet of the Envision located?

The air conditioning drain outlet of the Envision is located inside the left side panel of the front passenger seat. The functions of the air conditioning drain outlet are as follows: 1. Air conditioning water: This is the water produced during normal operation of the air conditioning system, and its production process is similar to that of distilled water, both generated through condensation. 2. Function: To discharge the condensed water produced during air conditioning cooling. Information about car air conditioning is as follows: 1. Car air conditioning: Refers to the air conditioning device installed in the car, which can cool, heat, ventilate, and purify the air inside the compartment, providing a comfortable environment for passengers, reducing driver fatigue, and improving driving safety. The air conditioning device has become one of the indicators to measure whether a car is fully equipped. 2. Structure: Generally includes refrigeration devices, heating devices, and ventilation devices. This combined device makes full use of the limited space inside the car, with a simple structure and easy operation.

How to unlock a car tire lock?

Car tire locks are opened using wheel lock keys. If you don't have the key, the lock cannot be opened, and you may need to seek help from professional locksmiths. If it's a disc-type wheel lock, it's best not to force it open as these locks typically have spikes. Tire locks are made entirely of steel plates, featuring characteristics such as anti-violence, anti-technical opening, anti-tire removal, and anti-key duplication, making them effective in securely locking illegal vehicle tires and preventing offenders from evading penalties. The wheel lock operates on a mechanical linkage principle, equipped with special keys and uniquely shaped handles, providing a dual security mechanism. Made from high-quality steel and high-strength stamping, its user-friendly design ensures no damage to the locked wheel. Wheel locks are designed to be safe and reasonable, with stable quality and performance, wide locking range, and flexible and convenient operation.

Can the first maintenance of Volkswagen be done at any 4S store?

Yes. As long as it is a 4S store authorized by FAW-Volkswagen, the first maintenance can be done. For the free first maintenance, you only need to bring the vehicle's driving license and maintenance manual. The following is the extended content: 1. The first maintenance of Volkswagen cars must be done at a 4S store. All car manufacturers stipulate that only cars that have their first maintenance done at a 4S store can enjoy the car quality guarantee. 2. The first maintenance of the car does not necessarily have to be done at the 4S store where the car was purchased. It can also be done at a 4S store that is closer and more convenient to go to. All 4S stores are connected nationwide, and the car manufacturer will recognize the first maintenance done at any store. 3. Basically, all car manufacturers stipulate that the first maintenance of the car must be done within 5,000 kilometers or half a year of driving, whichever comes first. Generally, it is most suitable to do the first maintenance when the car has been driven between 4,000 and 5,000 kilometers. However, if the car has been used for more than half a year, the 4S store will not provide the first maintenance.

What Happens When Starting in Fifth Gear?

Starting a car in fifth gear is very difficult and can easily damage the transmission, often leading to immediate stalling. Cars that use manual gear-shifting mechanical transmissions to adjust speed require manually moving the gear lever to change the gear engagement inside the transmission, altering the gear ratio to achieve speed adjustment. The gear lever can only be moved when the clutch is depressed. Gear Introduction: First Gear: Starting gear, used to initiate the car's movement. It has a similar gear ratio and performance as the reverse gear, making it unsuitable for prolonged high-speed operation. Generally, the car can shift to second gear once it gains momentum. Second Gear: Passing gear, mainly used for navigating complex road conditions and handling challenging situations, such as sharp-angle (right-angle) turns without special obstacles, crowded urban areas, steep slopes, and bumpy roads. Third Gear: Transition gear, primarily used for low-speed driving in urban areas. Depending on the situation, acceleration can smoothly transition to fourth gear, while deceleration can easily shift back to second gear. Fourth Gear: Cruising gear, mainly used for extended high-speed driving and economical operation. Most vehicles achieve their most fuel-efficient speed in the low-speed range of fourth gear.

Jetta VS5: Should I Use 92 or 95 Octane Gasoline?

According to the official vehicle manual recommendation, the Jetta VS5 should use 95 octane gasoline. In addition to checking the appropriate gasoline grade in the vehicle manual, you can also find it on the fuel tank cap, which will also be marked. Generally, the gasoline grade can also be determined based on the engine's compression ratio. Vehicles with an engine compression ratio between 8.6-9.9 should use 92 octane gasoline, while those with a compression ratio between 10.0-11.5 should use 95 octane gasoline. However, with the application of some new technologies, the gasoline grade cannot be solely determined by the compression ratio. A high compression ratio can also be tuned to use lower octane gasoline because, apart from the compression ratio, other factors such as ignition timing, turbocharging technology, and Atkinson cycle technology also play a role. Generally, the higher the gasoline octane number, the higher the octane value and the better the anti-knock performance. 92 octane gasoline contains 92% isooctane and 8% n-heptane, while 95 octane gasoline contains 95% isooctane and 5% n-heptane. If you occasionally use the wrong gasoline grade in the Jetta VS5, simply switch back to the correct grade after consumption. However, long-term use of the wrong gasoline grade can have the following effects: For vehicles recommended to use lower octane gasoline, using higher octane gasoline will not cause damage, but the increase in octane value will change the fuel's ignition point, leading to delayed combustion in the engine. This means both the engine's power output and thermal efficiency will decrease, resulting in poorer performance in actual driving experience. For vehicles recommended to use higher octane gasoline, using lower octane gasoline can cause engine knocking. Because the octane value is much lower, the gasoline's ignition point decreases and may ignite prematurely during the compression stroke. If combustion occurs before the spark plug fires during the compression stroke, resistance will arise during the upward stroke. This resistance will make the engine run very unstably. If it's only mild knocking, it may just increase noise without significant damage to the engine. However, if there is noticeable knocking, it indicates severe engine conditions, affecting not only driving stability but also causing abnormal wear on pistons and cylinders, and in severe cases, cylinder scoring.
