The engine noise will suddenly increase when accelerating. Here is some relevant information about tensioner pulleys: 1. Working principle: The tensioner pulley is a belt drive tensioning device. When the center distance of the belt cannot be adjusted, a tensioner pulley can be used to tighten the belt. The tensioner pulley is a follower wheel that presses against the belt to change the wrap angle of the pulley or control the belt tension, serving as the tensioning device for belt drives. 2. Application: The tensioner pulley is a tensioning device for adjusting belt drive systems, so it is generally used in engines of machinery such as electric motors, automobiles, conveyors, and lifting equipment. Tensioner pulleys are mainly used in belt drive systems where the center distance cannot be adjusted, such as V-belt drive systems.

What are the precautions after applying car wrap?

Precautions after applying car wrap include avoiding car washing. Here are specific precautions after applying car wrap: 1. Avoid car washing: It is best not to wash the car within a week after applying the car wrap. If the weather is rainy, this period should be extended. Washing the car before the wrap has fully adhered to the body may cause issues such as the wrap shifting, especially when using a high-pressure water gun to flush the gaps, which can lead to edges lifting or even the wrap peeling off. 2. Avoid adding small accessories or decorations to the car body after applying the wrap: During cleaning, this can cause bubbles at best or completely detach the wrap at worst.

Does peeling paint on car rearview mirrors have any impact?

Peeling paint on car rearview mirrors does not affect their functionality. Here are specific details about rearview mirrors: 1. Reasons for looseness: Generally, the looseness of the interior rearview mirror is caused by the hanging of a dashcam or heavy decorative items. If the connection between the interior rearview mirror and the windshield becomes loose, glue can be used to secure it. If the ball joint of the rearview mirror is loose, tools can be used to tighten the screws. 2. Adjustment method: For adjusting the interior rearview mirror, first adjust the seat to a comfortable position, then align the horizon to the center of the rearview mirror, ensuring a full and clear view of the rear windshield.

Will parking a car in an underground garage be affected by a typhoon?

Parking a car in an underground garage can be affected when a typhoon comes. The reasons are as follows: 1. Risk of flooding: Typhoon weather is usually accompanied by heavy rain, which may rush into underground parking garages, causing cars to be flooded. 2. Liability for damages: If a vehicle is flooded in an underground parking garage, the owner may have to bear most of the losses themselves. During a typhoon, cars should be parked in: 1. Open parking lots: Large parking lots around office buildings and shopping centers reduce the possibility of vehicles being hit by foreign objects to some extent. Although open spaces are more susceptible to typhoon impacts, they are definitely safer than parking spaces along busy streets. 2. Secure rooftop parking spaces: If there are no open parking lots, cars can also be parked in stable rooftop parking spaces, including those located on the first floor of community buildings. These parking spaces have stable structures, eliminating worries about cars being hit by heavy objects around them, and they also provide some shelter from wind and rain.

Why Does the Transmission Get Water Inside?

Transmission can get water inside because it has ventilation holes, which may form small water droplets due to temperature changes. These droplets vaporize under high temperatures and are expelled as steam. Below is an introduction to water ingress in transmissions: 1. Precautions: When water enters the transmission, the performance of the transmission oil is severely affected—not only is its lubrication performance compromised, but its power transmission capability also declines. This can lead to clutch slippage, followed by an increase in oil temperature, which may generate steam or even cause the oil-water mixture to boil. These viscous substances can accumulate in the valve body, causing blockages and affecting the transmission control system. 2. Explanation: Severe water ingress requires replacement of related components: Rubber components such as gaskets and seals need to be replaced; friction plates must be replaced because they consist of steel plates and high-density wood materials, which swell when exposed to water, affecting friction performance. Additionally, the transmission oil and differential oil must be completely replaced.

What does NIO's first charging pile benefit mean?

NIO's first charging pile benefit: includes installation, no cost for simple wiring within 30 meters, includes 30 meters of waterproof cable, national standard galvanized steel pipe or PVC waterproof pipe, ABB leakage protector, waterproof switch box; installation is carried out by NIO's original factory construction; three-year original factory warranty from the date of installation completion. Additional information: 1. Lifetime free remote charging benefit: This benefit has a major premise, which is that the number of charging times per year cannot exceed 12. Remote charging means that beyond 200 kilometers from the city where the NIO car license is applied for, you can choose free charging or battery swapping in a remote location. If you use NIO's dedicated charging pile for charging or go to a battery swap station for swapping, the cost will be borne by NIO. If you use a public charging pile for charging, you need to pay first, but NIO will refund the equivalent cost in the form of points in the app. 2. Lifetime free battery swapping benefit: (1) If the owner needs to install a home charging pile, NIO will give the owner a charging pile for free and waive the installation fee, but the length of the charging pile cable cannot exceed 30m, and any excess will be at the owner's expense. Under this premise, the owner's monthly battery swapping times will change from six times per month to four times per month. (2) If the owner does not want a charging pile, the monthly battery swapping times will remain six times. In either of the above cases, if the owner continues to swap batteries after the monthly quota is used up, they will have to pay; if the monthly battery swapping times are not used up, they will be cleared at the end of the month and cannot be carried over to the next month.

What are the symptoms of transmission failure in a Focus?

The transmission failure symptoms in a Focus include abnormal noises when in neutral, unusual noises from low-speed gears, reduction or elimination of noise in high-speed gears, abnormal sounds from various gears in the transmission, and noise from the transmission assembly. The relevant troubleshooting methods are as follows: If there is a metallic dry friction sound while driving and the transmission housing becomes hot, this is noise caused by deteriorated lubricant. It is necessary to add oil or check the oil quality, and replace it if necessary. If there is noise in neutral, and the sound disappears when the clutch pedal is depressed, this is usually due to loose front or rear axle bearings or meshing gear sounds. Any gear can produce noise, but if the noise comes from the rear bearing of the second shaft, it indicates severe looseness or damage to the bearing, which requires repair or replacement. When the vehicle is driving at low speed, it may produce irregular noises, and as the speed increases, more chaotic gear impact sounds and filtering noises may occur. If the noise is relatively loud but the cutting force is even, the vehicle can continue to be used for break-in. If the noise is severe or uneven, it should be disassembled for inspection and break-in, and adjusted or replaced if necessary.
