What are the signs of aging engine mounts?

The signs of aging engine mounts include: occupants feeling vibrations in the vehicle, hydraulic fluid leakage, jerky gear shifts, shaking when accelerating hard, and increased body resonance noise. Engine mounts are cushions that connect the engine to the vehicle body, primarily serving to absorb shocks and vibrations. Most are made of rubber, while high-end vehicles may use hydraulic versions. Located between the engine and the vehicle frame, engine mounts prevent engine vibrations from being directly transmitted to the body. Being rubber components, they harden and deteriorate over time. When engine mounts age, the vibrations caused by engine operation transfer directly to the vehicle body, making the shaking clearly noticeable inside the cabin.

Is the vehicle certificate no longer given to the owner after the car is registered?

After the car is registered, the vehicle certificate is indeed no longer given to the owner, as the original certificate is kept by the vehicle management office. Other materials retained by the vehicle management office for new car registration include: the fourth copy of the purchase invoice, the duplicate of the vehicle purchase tax, the duplicate of the compulsory traffic insurance, and a copy of the ID card. Materials required for new car registration: The fourth copy of the new car license fee invoice, the original and a copy of the owner's ID card (non-local residents also need to bring the original and a copy of their residence permit), the fourth copy of the new car purchase invoice (registration copy), the original duplicate of the vehicle purchase tax, the original duplicate of the compulsory traffic insurance, the original vehicle certificate, a photo of the new car, and the stamped vehicle identification number. Precautions for registration: Before paying the full amount, you should ask the car dealer to present the vehicle certificate and carefully compare whether the information on the certificate matches the car to avoid infringement of your legal rights. If the car dealer delays or refuses to deliver the vehicle certificate, consumers can file a complaint with the Market Supervision Administration or the Consumer Association. When entrusting a 4S store to handle the registration on your behalf, be sure to ask about all the conditions for registration to see if they are met to avoid wasting time and effort. When signing relevant contracts, read all the terms carefully and ask questions on the spot if anything is unclear. Non-local residents must have a residence permit to buy a car and register it in their place of residence.

What is the principle of antifreeze?

Antifreeze principle is: engine coolant is added with some substances that can lower the freezing point of water as antifreeze agents, to keep the cooling system from freezing in cold weather. Automotive antifreeze is also called antifreeze or non-freezing liquid, and its full name should be automotive antifreeze coolant, meaning coolant with antifreeze function, to enable the car to continue to be used in low winter temperatures. There are many types of automotive antifreeze agents, such as calcium chloride in inorganic substances, methanol, ethanol, ethylene glycol, glycerin, lubricating oil in organic substances, and common sugar, honey in daily life, etc., which can all be used as the mother liquor of antifreeze. After adding an appropriate amount of pure soft water, it can become antifreeze in the general sense.

Can I Correct the Wrong Turn Signal Immediately in Subject 3 Driving Test?

No, correcting the wrong turn signal immediately in the Subject 3 driving test is not allowed, and you will still be penalized 10 points. According to the scoring criteria of the Subject 3 test, failing to use or incorrectly using the turn signal before starting, turning, changing lanes, overtaking, or parking, or turning within less than 3 seconds after activating the turn signal, will result in a 10-point deduction. Scenarios involving turn signals in the Subject 3 test include: activating the left turn signal when starting, turning on the right turn signal at intersections for right turns, using the left turn signal for U-turns, activating the left turn signal at intersections for left turns, first turning on the left turn signal and then the right turn signal when overtaking, using the left turn signal when changing lanes, and activating the right turn signal when pulling over to park. During the vehicle preparation phase of the Subject 3 test, follow the correct sequence: first report to the examiner, then request a vehicle inspection. When starting, follow the order of lights, gear, horn, and brake. Maintain proper control of the steering during straight-line driving. When passing through crosswalks, bus stops, and school zones, reduce speed and shift down in advance. During oncoming traffic, slow down early and yield to other vehicles, avoiding crossing the non-motor vehicle lane line. When overtaking, observe the traffic conditions ahead and behind beforehand. If overtaking conditions are not met, wait until it is safe to complete the maneuver, and never overtake from the right. When pulling over to park, position the vehicle (on the right side) parallel and within 30 cm of the curb (or solid road edge line).

Can Frozen Windshield Washer Fluid Damage Car Components?

Frozen windshield washer fluid can indeed damage car components. Once the fluid freezes, it may cause the reservoir and hoses to crack. Continuously operating the washer pump to spray the frozen fluid could also lead to motor burnout. To better protect your vehicle during winter, it's advisable to use appropriate antifreeze washer fluid. Solutions for frozen washer fluid: 1. Use hot water to rinse the hoses and nozzles, then let the car sit in sunlight for thawing. Spray every 3-4 minutes afterward to prevent refreezing; 2. Start the engine and let it idle to generate heat for thawing assistance; 3. Add warm water to the washer reservoir. After thawing, completely drain the old fluid and replace it with new antifreeze washer fluid to prevent re-freezing.

Does the Volkswagen Lavida Plus have a particulate filter?

Volkswagen Lavida Plus does not come with a particulate filter across all its models. There are 11 variants of the Volkswagen Lavida Plus, none of which are equipped with a particulate filter, yet they still comply with the China VI emission standards. A particulate filter is a ceramic filter installed in the exhaust system of diesel engines, designed to capture particulate emissions before they are released into the atmosphere. It can reduce soot emissions from diesel engines by more than 90%, and the captured particulate matter is subsequently burned off during vehicle operation. How the particulate filter works: The diesel particulate filter is coated with platinum, rhodium, and palladium. The black smoke containing carbon particles emitted by the diesel engine enters the exhaust particulate trap through a dedicated pipeline. The densely arranged bag filters inside capture the carbon particles on a filter made of metal fiber felt. When the accumulated particles reach a certain level, the burner at the end automatically ignites, burning off the captured carbon particles and converting them into harmless carbon dioxide. To check if the Volkswagen Lavida Plus has a particulate filter, you can use the following three methods: Check the and to see if there is a particulate filter function. Additionally, you can carefully review the fault codes in the manual to see if there is a "particulate filter" warning light indicator; Look at the label on the oil cap. If the oil cap clearly indicates the use of 0W-20 grade oil, it means the vehicle is equipped with a particulate filter; Check if there is a cylindrical section on the exhaust pipe behind the three-way catalytic converter. If present, that is the particulate filter.
