Automotive lubricating oil can provide lubrication, reducing friction between rubber seals and window glass, effectively eliminating mechanical noise; it can also effectively clean window stains, prevent aging and corrosion of rubber seals, prevent water leakage from seals, and has functions such as moisture-proof sealing. The following are specific introductions to lubricating oil: 1. Applicable parts: Lubricating oil is suitable for parts such as windows, sunroofs, door hinges, engine hood hinges, electric rearview mirrors, and wipers, providing excellent lubrication effects for conditions like rust, jamming, and abnormal noises. 2. Classification: It is divided into engine oil, gear oil, grease, refrigeration oil, and vacuum pump oil.

Engine oil is like the lifeblood of an engine, and I must say it's particularly crucial. Right after an oil change, the engine runs noticeably smoother. During daily driving, it reduces friction between internal components, acting like a slippery protective film between parts. The oil also cleans carbon deposits and impurities, preventing sludge buildup that could clog oil passages. A friend once had blue smoke from his exhaust, which turned out to be caused by worn piston rings burning oil - a stark reminder for me to monitor oil consumption regularly. Whether in summer traffic jams with high temperatures or during cold winter starts, only the right viscosity can maintain a stable oil film. Most importantly, engine oil carries heat away to the cooling system, preventing cylinder scoring risks. I strictly change to full synthetic oil every 8,000 kilometers - this investment is far more cost-effective than engine repairs.

Spray a dedicated heat-insulating cleaner on the residual film adhesive, which will melt it in a short time, and then wipe it clean with a cloth. The maintenance methods for the front windshield include: 1. Use dedicated or suitable wiper blades and replace them in time; 2. Keep the glass surface clean; 3. Use automotive-specific glass cleaner.

How to Switch Between D Gear and S Gear?

To switch between D gear and S gear, simply push the gear lever. Automatic transmissions do not require the driver to manually shift gears; the vehicle will automatically select the appropriate gear based on driving speed and traffic conditions. The D gear in an automatic transmission refers to the manual mode of a semi-automatic transmission, allowing manual control over gear shifting (both upshifting and downshifting). When using D gear, there is no need to press the brake or release the accelerator. The S gear is the sports mode of the car, where the transmission can shift freely, but the shifting timing is delayed. This keeps the engine at higher RPMs for a longer period, allowing the car to maintain low gear and high RPM for extended periods, resulting in greater torque output and acceleration.

What does the yellow light on Chery RVM mean?

The yellow light indicates a malfunction that requires troubleshooting and timely repair. Below is the relevant information: Principle: RVM utilizes submillimeter-wave radar installed on the rear bumper to detect adjacent lanes and the distance from vehicles behind. When a lane change poses a danger, it alerts the driver by flashing indicator lights and sounding an alarm. This system employs 24GHz submillimeter-wave radar with a wide sensing range that is less affected by adverse weather or sunlight, enabling high-precision detection of approaching vehicles from the rear even at high speeds.

Can the Old Inspection Sticker Be Removed?

The old inspection sticker can be removed and replaced with the new one. Additional Information: 1. Annual inspection, colloquially referred to as 'annual review,' involves a safety check of the vehicle conducted every year or every two years. This comprehensive inspection includes the horn, brakes, axle weight, chassis, ignition system, lighting system, exhaust system, license plate installation, and more. 2. According to the new traffic regulations introduced in 2013: Vehicles without the compulsory traffic insurance sticker will be impounded by traffic authorities and fined. Even if the vehicle is insured, failure to display the sticker in the designated location will result in a 200 yuan fine and a deduction of 1 point from the driver's license.

What Causes the Burning and Noise of the Release Bearing?

Release bearing burning and noise reasons: Burning caused by excessively high working temperatures, commonly seen when drivers habitually use the half-clutch technique, keeping the clutch in a semi-engaged and semi-disengaged state. This causes dry friction heat from the clutch to transfer to the release bearing, leading to the thinning and loss of lubricating grease until the temperature reaches a certain level, resulting in burning damage. The clutch release bearing is installed between the clutch and the transmission. The release bearing housing is loosely fitted on the tubular extension of the transmission's first shaft bearing cover. A return spring ensures that the shoulder of the release bearing always presses against the release fork and retracts to the rearmost position, maintaining a gap of approximately 3 to 4mm with the end of the release lever.

How to Check Car Glass Dimensions?

Cannot be checked, you need to measure it yourself. 1. Size introduction: The length of the front windshield is generally about 145CM, with widths ranging from the smallest mini of 40CM to the largest Peugeot 5008's 105CM. 2. Model introduction: There are black characters on the glass indicating the model, which is the name given by the manufacturer to vehicles of the same type, brand, category, series, and body style. 3. Maintenance: Use dedicated or suitable wiper blades and replace them in time (usually once a year) to avoid scratching the front windshield; always keep the front windshield clean. If there are debris stuck, try not to use the wipers to remove them. Instead, use a towel or other tools to carefully remove them.
