Toothpaste can corrode car paint when used for washing, and the reason is: toothpaste contains abrasives. Using toothpaste to wash a car can wear down the paint to some extent, but it can also be used to repair minor scratches and dents on the car's paint surface. The method for removing car scratches with toothpaste is: 1. Wet a cloth and wipe off the dust on the scratched area; 2. Squeeze toothpaste onto a napkin; 3. Gently rub the scratched area with the toothpaste until the scratch is no longer visible; 4. Wet a cloth and wipe off the toothpaste from the car body. Methods for maintaining car paint include: 1. Promptly remove dust from the car body to minimize the adsorption of dust due to static electricity; 2. Rinse off rain stains with clean water as soon as possible after rain to avoid damaging the paint surface; 3. Avoid washing the car under direct sunlight or high temperatures; 4. Use clean, soft cloths or sponges when scrubbing the car to prevent metal shavings and sand particles from causing scratches.

How to Check for Clutch Slippage?

Methods to check for clutch slippage include: 1. Rapidly pressing the accelerator results in a quick increase in RPM but difficulty in acceleration; 2. When starting, even after fully releasing the clutch pedal, you still feel insufficient power or difficulty in starting; 3. The slippage is more noticeable when the car is heavily loaded going uphill or driving on muddy and soft roads, and in severe cases, a burning smell may emanate from the clutch; 4. During driving, pressing the brake does not cause the engine to stall but it continues to run normally. If clutch slippage occurs, timely maintenance is required, including appropriate lubrication, repair, or replacement based on the situation to ensure driving safety. The clutch is located inside the flywheel housing between the engine and the transmission. The clutch assembly is fixed to the rear plane of the flywheel with screws, and the output shaft of the clutch is the input shaft of the transmission.

What Happens If Engine Oil Is Not Changed for a Long Time?

The effects of not changing engine oil for a long time are: 1. The oil becomes ineffective and deteriorates, failing to provide lubrication and protection, which increases wear on mechanical components; 2. The oil becomes watery, losing its sealing function and leading to gas leakage; 3. Reduced cooling effect; 4. Deposited impurities corrode internal components; 5. Increased sludge formation makes it difficult for the oil pump to maintain pressure, resulting in engine failure. The functions of engine oil are: 1. To cushion the impact load on pistons, piston rings, connecting rods, and crankshaft bearings; 2. To form a sealing ring between the piston rings and pistons, reducing gas leakage and preventing external contaminants from entering.

What is the standard tire pressure for cars in winter?

The standard tire pressure for cars in winter is between 2.5 and 2.7 bar. Precautions for adjusting tire pressure during inflation include: 1. Check the pressure multiple times during inflation to avoid over-inflation, which may cause tire bursts; 2. After stopping the vehicle, wait for the tires to cool down before inflating; 3. Inspect the valve stem before inflating; 4. Ensure that the air being pumped in does not contain moisture or oil to prevent deterioration and damage to the inner tube rubber; 5. Avoid exceeding the standard tire pressure value, as it may cause excessive stretching of the cords, leading to reduced strength; 6. After inflation, check for any leaks at the valve stem and tighten it to prevent dirt from entering. Tire pressure refers to the air pressure inside the tire, which affects the comfort and handling stability of the vehicle.

How Often Should the Spark Plugs Be Replaced on a Volkswagen Tiguan?

Volkswagen Tiguan spark plugs should be replaced approximately every 25,000 kilometers. The function of spark plugs is to introduce high-voltage electricity into the combustion chamber, causing it to jump across the electrode gap and generate a spark, thereby igniting the combustible air-fuel mixture in the cylinder. Taking the 2019 Volkswagen Tiguan 2WD Elite model as an example, it belongs to the compact SUV category, with body dimensions of 4,486mm in length, 1,839mm in width, and 1,646mm in height, a wheelbase of 2,681mm, and a fuel tank capacity of 60 liters. The 2019 Volkswagen Tiguan 2WD Elite is equipped with a 1.4L turbocharged engine, delivering a maximum horsepower of 150PS and a maximum power speed range of 5,000 to 6,000 rpm.

What is a Clutch?

A clutch is a device that transmits the power of a car engine to the axle in an on-off manner. It is installed between the engine and the transmission and is the assembly component in the car's drivetrain that is directly connected to the engine. The functions of the clutch are: 1. To ensure smooth starting of the car; 2. To achieve smooth gear shifting. The maintenance methods for the clutch are: 1. Clean thoroughly before installation to remove anti-rust grease and debris; 2. For wet electromagnetic clutches, lubricating oil needs to be added between the friction plates during operation; 3. During coaxial installation, axial fixation is required to prevent axial movement between the driving part and the driven part; 4. For split-shaft installation, the coaxiality between the driving part and the driven part shafts should not exceed 0.1mm.
