What are the considerations when purchasing a car?

Why does the engine make abnormal noises when starting the car?

The reasons for abnormal noises from the engine when starting the car are as follows: 1. Valve noise: After starting the car, the engine makes a "click-click-click" sound, which is the sound of the valves, especially after a cold start when the oil pressure has not yet built up and the valves are not properly lubricated. 2. Excessive valve clearance or oil leakage at the camshaft: The valve clearance needs to be adjusted or the relevant oil seals need to be replaced. 3. Use of unqualified engine oil: For example, using thinner oil in high-mileage cars, etc. Replacing the oil can eliminate the abnormal noise. 4. Sound of shock waves and piston collisions: Diesel engines, due to direct fuel injection, produce a large explosive force. These explosive forces form shock waves that push against the pistons, creating the sound of shock waves and piston collisions, which causes abnormal engine noises.

Which is better, the Prado VX or TX?

Introduction to the Prado VX and TX is as follows: 1. The Prado TX version can be simply understood as the base model, which comes without additional configurations, making it popular among modification enthusiasts. This model is mainly found in the Middle East version, specifically the Kuwait version, and the spare tire can be either under-mounted or rear-mounted. 2. The Prado VX is the high-end version. Firstly, it features the classic rear-mounted spare tire in terms of appearance, and the interior is upgraded with wood grain trim. Secondly, it is equipped with a liquid crystal instrument panel that includes a trip computer, which is a distinguishing advantage over other versions. The VX model uses a four-link suspension system, offering slightly better handling and off-road capability compared to other versions. Through comparison, the Prado VX is better than the TX.

What can be used to clean the throttle body?

The throttle body should be cleaned using professional throttle body cleaner. The following are precautions when cleaning the throttle body: 1. The throttle body is a control device that regulates the amount of air entering the engine: it is connected to the air filter on one side and the engine block on the other, making it prone to carbon buildup. Its cleanliness directly affects the responsiveness of the car's acceleration. 2. When cleaning the throttle body: it should be removed for cleaning, and the cleaning solution should not be sprayed in only one direction, as this could spray onto the electrical components of the throttle body, potentially causing damage. 3. The throttle body cleaner should be sprayed onto areas with heavy carbon buildup: wait 5-10 minutes for the carbon to dissolve, then use a clean brush to scrub and a clean towel to wipe it off. Before reinstalling, ensure the throttle body is completely dry to avoid damaging the position sensor. To speed up the drying process, use an oil-absorbing paper to remove excess oil from the connecting parts of the throttle body.

What are New Energy Vehicles?

New energy vehicles refer to automobiles that utilize unconventional vehicle fuels as power sources, integrating advanced technologies in vehicle power control and driving systems to form vehicles with advanced technical principles, new technologies, and novel structures. The types of new energy vehicles are as follows: 1. Battery Electric Vehicles (BEVs): A type of vehicle that uses a single battery as the energy storage power source. It employs the battery to store energy and supplies electricity to the motor, which drives the vehicle. 2. Hybrid Electric Vehicles (HEVs): Vehicles whose driving systems are powered by two or more individual systems that can operate simultaneously. The driving power is calculated based on the actual driving conditions of the vehicle. 3. Other new energy vehicles: Include those using high-efficiency energy storage devices such as supercapacitors and flywheels. Currently, in China, new energy vehicles mainly refer to battery electric vehicles, extended-range electric vehicles, plug-in hybrid electric vehicles, and fuel cell electric vehicles. Conventional hybrid vehicles are classified as energy-saving vehicles.

How Often Should the Coolant Be Changed in a Honda Car?

For Honda cars that run for extended periods, high-quality coolant should generally be changed once a year, while those with shorter running times can have it changed every two years or every 30,000 kilometers. How to Change the Coolant: Before completely replacing the coolant, conduct a thorough inspection to check for any signs of leakage or cracks in the pipes, with particular attention to the five-way water pipe. The coolant flows through the five-way pipe and is then distributed to different parts of the car to function. If there is any leakage of coolant in this section, the water pipe should be replaced or the connection re-secured as needed. Drain the old coolant, then flush the fluid channels with clean water. Add clean water to the coolant reservoir, then continue filling the reservoir with water so that it continuously flows through the engine cooling system. Start the engine and let it idle for 3 to 5 minutes to circulate the water. The water initially flowing out of the reservoir will be slightly pinkish; continue adding clean water until the outflow is clear. Note: Don’t forget to remove the heater hose and drain the water from the heater core. About an hour after draining, add the new coolant through the radiator hose. Then, pour another container of coolant into the reservoir until it is nearly full. Start the engine and let it run for about 10 minutes. During this time, the coolant level will drop slightly as air is purged from the cooling system. Top up the coolant to the "MAXT" mark on the reservoir.
