Engine vibration when the air conditioner is turned on can be caused by the following reasons: Throttle Carbon Buildup: As the vehicle accumulates more mileage, carbon deposits can form in various parts, especially in the throttle. If the throttle is heavily soiled, it can obstruct air intake, causing the engine to struggle or barely manage to power the compressor. This results in noticeable vibration when the air conditioner is turned on. Engine Mount Damage: Even during normal operation, the engine vibrates, including when the compressor is activated. However, the engine mounts typically filter out some of this vibration, making it less noticeable. If the engine mounts are collapsed or damaged, the engine's balance is disrupted. Turning on the compressor might then reach a resonance frequency, amplifying the vibration.

What model of tires does the 10th generation Accord use?

The 10th generation Accord uses three specifications of tires: 215/60R16, 235/45R18, and 225/50R17. More related information is as follows: 1. Introduction: Tires are a crucial component of a car, directly affecting driving stability and safety. Being rubber products, tires age over time with prolonged use, hence requiring regular replacement. Under normal conditions, tires installed on a car can last for four years, so it is recommended to replace them every four years. When purchasing new tires, always check the production date, as tires generally have a shelf life. Normally, the shelf life of unused tires is three years; if they have been in storage for more than three years, they should not be purchased. 2. Notes: After installing new tires, it is essential to perform a dynamic balance test on each wheel to prevent abnormal vibrations during high-speed driving. Abnormal wheel vibrations at high speeds can adversely affect the car's handling and driving stability. During regular use, it is important to frequently check the tire pressure, as it is critical for tire performance. Tire pressure should neither be too high nor too low. If the pressure is too high, it reduces the contact area between the tire and the ground, thereby diminishing grip. If the pressure is too low, it can cause wave-like deformation of the tire during high-speed driving, accelerating the aging process of the tire.

How to Check the Tire Specifications of a Jeep Wrangler?

jeep Wrangler's original tire models come in two types: 245/75-R17 and 255/75-R17, with the specifications printed on the tires. Here, 245/255 represents the tire width in millimeters. 75 indicates the aspect ratio, meaning the tire thickness is 75% of the width, and R17 denotes the rim diameter in inches. The original tires of the Wrangler focus more on off-road traction. If owners have higher performance requirements for tires, they may consider switching to AT tires. Below is an introduction to the Jeep Wrangler: 1. The core technology of the Jeep Wrangler is the Rock-Trac part-time four-wheel-drive system. Part-time four-wheel drive means the driver manually engages or disengages the transfer case to switch between two-wheel and four-wheel drive modes. This relatively pure system requires drivers to judge road conditions and choose the drive mode based on their own experience. 2. The Wrangler Rubicon features an off-road performance integration block, which significantly enhances off-road capabilities. However, these performance features are only available in vehicles that have been modified with high-performance parts originally purchased from the aftermarket. 3. The current Wrangler model uses a five-speed automatic transmission, which offers better performance, smoother shifting, a wider rpm range, and improved fuel efficiency compared to the older four-speed transmission. Higher transmission rpm can enhance acceleration performance while maintaining the engine's torque output. Additionally, the five-speed automatic transmission is set with a lower first gear ratio to achieve greater low-gear output torque, thereby improving the Wrangler's off-road capability in extreme environments.

What does ETC mean at highway toll booths?

Highway ETC (Electronic Toll Collection) translates to electronic toll collection, which is a non-stop toll collection system. Highways are equipped with one or more ETC lanes. The ETC payment method involves: specialized short-range microwave communication between the vehicle-mounted RFID tag installed on the windshield and the microwave antenna on the ETC lane at the toll station. This is connected to the bank's backend settlement system via software networking technology, allowing vehicles to pass through bridge and highway toll stations without stopping to pay tolls. Banks that install this type of ETC express card operate on a post-payment system. ETC application requirements are as follows: Provide the original and photocopies of the vehicle owner's valid ID card and vehicle registration certificate. The photocopy of the driver's license should include the page with the most recent annual inspection stamp. Complete a postal credit card application form, which will be used to bind the ETC card. After receiving the credit card, swipe it twice and present the POS receipt to a designated postal outlet to receive and install the ETC onboard device for free, with no additional charges. Applicants must be between 18 and 60 years old. The vehicle must be registered under the applicant's name. Here are some considerations for installing ETC: Do not obstruct the driver's view. It is best to install it behind the rearview mirror. Many car models have steeply angled windshields, which can reduce the driver's field of vision. Installing the ETC device without considering this may increase blind spots. Install it on the right side behind the rearview mirror to avoid blocking the view. Avoid interfering with charging. The ETC electronic tag consumes power but generally does not require charging or battery replacement, as it has a built-in solar panel on the back for self-charging. Therefore, during installation, avoid the blackened areas on the windshield and positions that may block the solar panel. Do not remove the device once installed. The adhesive in the middle has an anti-tamper switch. Once installed, the windshield will press this switch in. If the device is removed, the switch will pop out and lock the electronic tag, rendering it unusable. You will then need to visit an ETC service point to unlock it. This mechanism prevents multiple vehicles from sharing one device. When using ETC, note the following: The ETC transaction sensing range is 8 meters. To avoid paying for the vehicle in front due to a faulty ETC device, maintain a distance of at least 10 meters from the vehicle ahead. The ETC lane recognition speed is 20 km/h. Driving too fast may prevent the system from reading the vehicle's information, leading to payment failure. If using a debit card linked to ETC, insufficient balance may also cause payment failure.

Does Cadillac require the first maintenance in 3 months?

Not necessarily within three months. Generally, since the engine, transmission, etc., of a new car are all brand new, in order to maintain the lifespan of the components, it is stipulated that the first maintenance should be done at 3 months or 5,000 kilometers. This means if you have only driven 2,000 kilometers in 3 months, you still need to go for the first maintenance. Similarly, if you reach 5,000 kilometers in 2 months, you also need to go for the first maintenance. The 3 months or 5,000 kilometers is determined by whichever comes first. After the first maintenance is done, the second maintenance or subsequent ones can be delayed by a month or two without much issue. However, the first maintenance for a new car must be done within three months. This is a mandatory requirement for new car maintenance. The first maintenance time is determined by either the mileage or the stipulated time, whichever comes first. In other words, if the mileage is reached before the time, you need to go for the first maintenance, and if the time is reached before the mileage, you also need to go for the first maintenance. Therefore, once the time is up, you must go; otherwise, it will be considered as forfeiting the warranty. The first maintenance of a car refers to the initial service, which is generally at 5,000 kilometers/6 months (with a few exceptions). Many brand 4S shops, in order to shorten the maintenance cycle for customers, have changed to remind customers to do maintenance at 3,000 kilometers/3 months, with the two values being determined by whichever comes first. The first maintenance is free, but if it is overdue, you will need to pay for the maintenance yourself, and it will be considered as forfeiting the warranty rights. In the future, if there are any quality issues with the car, they will not be covered under warranty.

What is the purpose of an air filter?

The function of an air filter: To filter out particulate impurities in the air, ensuring that a sufficient amount of clean air enters the cylinders, and preventing floating dust in the air from being sucked into the engine, which can accelerate the wear of piston assemblies and cylinders. According to the car's maintenance manual, the air filter should generally be replaced every 10,000 to 20,000 kilometers or during every other maintenance interval. However, it is recommended to clean the air filter every 5,000 kilometers to reduce the buildup of throttle sludge. The location of the car's air filter element is determined by the intake form and the engine's structure. It is usually located in the air cleaner on the engine's intake pipe. There are two types of air filters in cars: dry and wet. Dry filters are made of paper or organic materials, while wet filters are made of metal mesh. Air filter: It is a type of filter, also known as an air filter cartridge, air cleaner, or air element. It is mainly used in engineering vehicles, cars, agricultural vehicles, laboratories, sterile operating rooms, and various precision operating rooms as an air filter. During operation, the engine sucks in a large amount of air. If the air is not filtered, the suspended dust in the air will be drawn into the cylinders, accelerating the wear of piston assemblies and cylinders. Larger particles entering between the pistons and cylinders can cause severe cylinder scoring, especially in dry and sandy working environments. The air cleaner is installed in front of the carburetor or intake pipe to filter out dust and sand particles from the air, ensuring that sufficient and clean air enters the cylinders. Using an excessively dirty air filter while driving can cause insufficient engine intake, leading to incomplete fuel combustion, unstable engine operation, reduced power, and increased fuel consumption. Therefore, it is essential to keep the air filter clean. The car's air cleaner is a device that removes particulate impurities from the air, consisting of one or several components that clean the air. Its main function is to filter out harmful impurities from the air before it enters the cylinders, reducing early wear of the cylinders, pistons, piston rings, valves, and valve seats. Therefore, before air enters the cylinders, it must pass through the fine filtration of the air cleaner. An excessively dirty air cleaner can cause poor engine performance, excessive fuel consumption, and engine damage. When inspecting the air cleaner, if it is found to have minimal dust and light blockage, it can be cleaned by blowing compressed air from the inside out and reused. An overly dirty air filter should be replaced promptly.

How to Read Tire Pressure Parameters?

You can use a tire pressure gauge to check the specific values of tire pressure. Here is the correct method for using a tire pressure gauge: 1. The central line of the pressure measurement port forms a 90°-180° angle with the axis of the gauge body. The scale is a rectangular prism, with a range of 0.07Wpa-0.4Wpa. Before reading, gently tap the instrument's casing or surface glass with your finger to eliminate friction in the transmission mechanism. 2. When observing, the pointer should overlap with the mirrored pointer. The value indicated by the pointer at this time is the pressure reading, accurate to one decimal place. Read the temperature value on the pressure gauge, also precise to one decimal place. 3. Align and press the measurement end slot of the pressure gauge with the tire valve stem. The pointer on the tire pressure gauge will deflect, and the indicated value is the inflation pressure of the tire. Alternatively, the gauge's indicator rod may be pushed out by the pressure, displaying the inflation pressure. The greater the internal pressure, the more the pointer deflects. Here is additional information: 1. Inner scale values: psi (pounds per square inch); outer scale values: kgf/cm² (engineering atmosphere) = 1.033 standard atmospheres = 1.02 bar. 2. For passenger car tires, the pressure is generally between 2.0 and 2.5 bar, not exceeding 3.5 bar. 3. For light truck tires, typically 6-ply, the pressure is between 3.0 and 3.5 bar; for 8-ply tires, between 4.0 and 4.5 bar; and for 10-ply tires, not exceeding 5.5 bar. 4. For trailer tires, the pressure generally does not exceed 4.2 bar.
