What Causes the Buzzing Noise Inside the Pajero While Driving?

The reasons for the buzzing noise inside the Pajero while driving are as follows: 1. Loose items in the storage compartments or glove box, or loose wiring from aftermarket electronic devices. Disorganized items in the storage compartments or glove box, even the nose pads of sunglasses in the glasses case can rattle. You can use your fist to tap on certain areas inside the car. If a noise occurs when tapping a specific area, check the surroundings for any loose items. Remove or secure them one by one and tap again to confirm. 2. The noise persists regardless of speed, and its frequency increases with speed. This is mainly related to the drivetrain components, such as tires or CV joints. You can visit a repair shop and use a lift to identify the cause. 3. The noise is irregular and unrelated to speed, sounding like tapping from outside the car. In this case, pay attention to the door frame area, organize loose items in the trunk, and check for debris under the front windshield. Also, check if there are plastic bags or other debris hanging under the car. Regularly clean the engine compartment to keep the floor clean. 4. When idling, standing in front of the car reveals a "whooshing" noise synchronized with the engine RPM. If you have replaced the alternator pulley or if the car has over 80,000 kilometers without a pulley replacement, the cause is simple—it's the pulley. Visit a repair shop to check the alternator pulley, as it may be aging or a substandard replacement.

How many times do you need to press the one-button start to start the car?

Here is an introduction to the one-button start function: 1. Nowadays, the vehicle's computer operates at increasingly faster speeds, so you can simply press the one-button start while stepping on the brake to start the car directly. 2. The one-button start does not require pressing two or three times. The original design of a segmented function was merely to facilitate the use of multimedia or lights without starting the engine, not to complicate the starting process. 3. Regarding the operation of the one-button start, when the vehicle is turned off, pressing and holding the one-button start for 3 seconds without stepping on the brake will only power on the vehicle without starting it. Alternatively, some models require pressing the ignition switch twice consecutively. Therefore, it is not universally true that the one-button start can only power on the vehicle but not start it. 4. If the one-button start is accidentally pressed while the vehicle is in motion, it will not cause the engine to shut down. Vehicles equipped with a factory-installed one-button start feature have protective mechanisms to prevent mechanical damage and erroneous operations.

Can You Keep High Beams On All the Time on the Highway?

High beams can be kept on all the time on the highway. There are no regulations prohibiting the use of high beams on highways. When the road is too dark and affects driving, high beams can be used appropriately, but care must be taken not to interfere with other drivers. Relevant information about using high and low beams is as follows: When high beams should not be used: On roads without central barriers or center lines, drivers should switch to low beams when meeting an oncoming vehicle at a distance of more than 150 meters at night. Low beams should also be used when meeting non-motorized vehicles on narrow roads or bridges. High beams should not be used when a following vehicle is driving close to the vehicle in front. When high beams can be used: High beams can be used when the distance to the vehicle in front exceeds 150 meters. If there is a central barrier, such as grass or a median strip, using high beams will not affect oncoming vehicles.

Can I add antifreeze by myself?

Antifreeze can be added by yourself, but it is necessary to choose the same brand, same model, and same specification of antifreeze product. Add appropriately based on the remaining antifreeze content in the engine. Antifreeze replacement cycle: For vehicles that run for long periods, such as taxis, high-quality antifreeze generally needs to be replaced once a year. For vehicles with shorter running times, it can be replaced every two years or every 30,000 kilometers. To prevent excessive foam formation, which reduces the heat exchange efficiency between the antifreeze and engine components, ensure the product is within its validity period when adding. Long-lasting antifreeze can have a validity period of up to three years. If suspended matter, sediment, or signs of deterioration or discoloration are found in the antifreeze, it should be replaced promptly, and the system should be cleaned. Antifreeze replacement method: Before completely replacing the antifreeze, conduct a thorough inspection to check for any signs of leakage or cracks in the pipes, with a focus on the five-way hose. The five-way hose is named for its five connections to various parts, and the antifreeze is distributed to different sections of the car after flowing through it. If there is any leakage of antifreeze in this part, replace the hose or re-secure the connections as needed. Drain the old antifreeze, then flush the liquid channels with clean water. Add clean water to the antifreeze reservoir and continue to pour water into the reservoir, allowing it to flow continuously through the engine cooling system. Then, start the engine and let it idle for 3 to 5 minutes to circulate the water. Initially, the water flowing out of the reservoir may have a faint pink color. Continue adding clean water until the water coming out is clear. Note: Do not forget to remove the heater hose and drain the water from the heater core.

Why is the Land Rover Evoque air conditioning not cooling?

Common reasons for car air conditioning not cooling are likely due to minor refrigerant leakage or excessive refrigerant. Here are solutions for car air conditioning refrigerant issues: 1. Minor refrigerant leakage: This can be observed through the sight glass on the dryer tank. During normal operation, if continuous slow bubbles appear in the sight glass, it indicates insufficient refrigerant. If obvious bubble flipping occurs, it means severe refrigerant shortage. The solution is to add refrigerant, but note: if adding from the low-pressure side, never invert the refrigerant bottle; if adding from the high-pressure side, never start the engine. 2. Excessive refrigerant: Also observable through the sight glass on the dryer tank. If no bubbles are visible during operation and none appear after compressor shutdown, it confirms excessive refrigerant. If excessive pressurized cooling oil is present, somewhat turbid bubbles will be visible during normal operation. If refrigerant is indeed excessive, it can be slowly released from the low-pressure side maintenance port of the air conditioning system.

Why is there abnormal noise when turning on the AC button?

When the air conditioner is turned on, abnormal noise from the engine area mainly has two causes: 1. Metal friction sound emitted when the compressor electromagnetic clutch engages. 2. Squeaking sound caused by excessive force on the air conditioner belt. Note: These two situations only occur when accelerating with the air conditioner on. The specific reasons are as follows: 1. Lack of refrigerant oil: Metal friction sound is emitted when the compressor electromagnetic clutch engages, usually due to insufficient refrigerant oil for lubrication inside the compressor. When refrigerant oil is lacking, the internal piston of the compressor does not receive adequate lubrication, resulting in metal friction sounds under the high pressure of the refrigerant. 2. Electromagnetic clutch failure: The electromagnetic clutch itself is faulty, with internal bearing damage causing abnormal noise, requiring compressor replacement.
