Volkswagen Tharu spark plugs should be replaced every 20,000 kilometers. The replacement method is as follows: 1. Prepare a complete set of disassembly tools, and remove the intake pipe and antifreeze storage tank; 2. After removal, pull out the ignition coil, and use a socket and wrench tools to remove the spark plug; 3. Compare the old and new spark plugs. When installing the new spark plug, slide it slowly along the inner wall to avoid affecting the ignition gap. The function of the spark plug is to discharge the pulse high voltage sent by the high voltage wire, break down the air between the two electrodes of the spark plug, and generate an electric spark to ignite the mixed gas in the cylinder. The Volkswagen Tharu has a length, width, and height of 4453mm, 1841mm, and 1632mm respectively, with a wheelbase of 2680mm, a top speed of 200 kilometers per hour, and is equipped with a 7-speed dual-clutch transmission.

As a Volkswagen Tharu owner for five years, I've learned that spark plugs should be replaced every 40,000 to 50,000 kilometers. The manual suggests 30,000 to 60,000 kilometers, but in my experience, frequent stop-and-go city driving with traffic lights accelerates spark plug wear, making replacement necessary by 40,000 kilometers. Failing to replace them promptly caused my car to vibrate noticeably at idle and fuel consumption to spike—something I deeply regret. Now, during routine maintenance, I always have the technician check the electrode color; if it turns black, I replace them immediately. Changing spark plugs only costs a few hundred yuan, and the fuel savings make it well worth it. If the road conditions are rough, replacing them a bit earlier is even better, as it extends engine life, ensures smoother driving, and provides safety and peace of mind.

I've been driving for decades, and spark plugs are something you can't be careless about. For the Volkswagen Tharu, they generally need to be replaced every 40,000 to 60,000 kilometers. If the road conditions are bad or there's a lot of dust, you should shorten the interval. If you don't replace them for a long time, the ignition will be uneven, and the engine will shake like an earthquake. The cost of towing and repairs will be even more expensive. During maintenance, pull them out to check—if the gap is too large, it's time to replace them. I recommend changing them around 50,000 kilometers for the safest bet—don't try to save a little money. Using low-quality fuel also damages spark plugs, so choose reputable gas stations. After replacement, the car will noticeably run smoother, making long trips worry-free.

What to do if the ETC device falls off by itself?

ETC tags have an anti-removal feature. Once they become loose or fall off, you need to go to the original issuing point or the provincial expressway ETC service center to reactivate and reinstall them. If the ETC device falls off, you can use the manual lane for toll payment, so there's no need to worry about this. Be sure to keep the ETC card and transmitter device waterproof, avoid demagnetization, prevent violent damage, and prohibit disassembly by non-professionals.

Where is the car radiator filler port located?

Car radiator filler port is generally located on the right side of the engine compartment. The radiator is usually positioned behind the air conditioning condenser. When opening the engine compartment, only the radiator's upper cover is visible. To clearly see the radiator's position, the front bumper cover needs to be removed. The liquid added to the radiator is antifreeze. Before adding water, it's necessary to cool down and reduce pressure: If the water temperature becomes too high or the radiator's water level is insufficient, immediately stop the car. Let the engine idle and use the fan for heat dissipation. Do not turn off the engine to prevent cylinder sticking. After the water temperature has decreased somewhat, open the radiator's drain switch to let some hot water and steam escape, reducing the steam pressure in the cooling system. This prevents hot air from spraying out and causing injury when opening the radiator cap. Additionally, cooling down avoids sudden addition of cooling water to a hot engine, which could crack the cylinder head. Be cautious when opening the radiator cap: Stand on the upwind side of the radiator. Wrap the cap with a wet cloth, tilt your head and body to one side, and open it slowly. Add water slowly: Since the water jacket and radiator are at high temperatures when the engine is hot, adding water too quickly can cause the cooling water to evaporate and vaporize rapidly, creating vapor lock. This suddenly increases the steam pressure in the system, leading to a secondary water spray accident. Therefore, when adding water, use a thin stream to add slowly. Only after no large amount of hot air is escaping from the radiator port should you gradually increase the filling speed.

How to Prevent Rear-End Collisions on Highways?

Human factors such as speeding, fatigued driving, drunk driving, failure to maintain a safe distance, illegal lane changes, overloaded trucks, overcapacity buses, and improper braking. Rearview mirrors allow you to observe whether there are vehicles behind you and roughly estimate the distance from the following vehicle. When driving at high speeds, the minimum distance between vehicles should be kept above 50 meters. Using lights can effectively reduce the risk of being rear-ended by alerting drivers and speeding up their reaction time. Use lights to warn drivers in front and behind.

Can a car be licensed in a different location?

Cars can be licensed in a different location, but a temporary residence permit is required. With the temporary residence permit, ID card, car purchase invoice, tax payment certificate, vehicle qualification certificate, and other procedures, you can go to the local vehicle management office to complete the licensing process. Process and precautions for purchasing and licensing a car in a different location: Ensure complete vehicle procedures: After purchasing a car in a different location, you need to ensure that the materials provided by the 4S store are complete, such as the car invoice, vehicle qualification certificate, maintenance manual, etc. These items are essential. If the 4S store fails to provide any of them, it will affect the subsequent licensing and maintenance of the new car. Prepare a temporary license plate: Next, you need to prepare a temporary license plate, which can be obtained from the car dealer or purchased separately. However, be sure to pay attention to the validity period of the temporary license plate. Using an expired temporary license plate may result in the insurance company refusing to cover claims after an accident. Before departure, contact the local insurance company agent in advance and provide the vehicle's chassis number. Drive the car back to the licensing location for licensing: The car owner needs to go to the local State Taxation Bureau to pay the vehicle purchase tax, and then they can proceed to the vehicle management office to license the new car. According to China's regulations on new car licensing procedures, as long as the vehicle has the four basic procedures—a formal invoice, qualification certificate, purchase tax, and compulsory traffic insurance—it can be licensed.

What to Do When White Paint Gets on the Protective Plate?

Paint thinner can be used to dilute the paint, which works very well, but banana oil is toxic, volatile, and corrosive, so extra caution is needed when using it. Gasoline can also dissolve paint with good results and without much corrosiveness. Asphalt cleaner can dissolve paint. Spray it evenly on the paint, wait for a while until the paint softens and dissolves, and then rinse it off with clean water.
