What to Do About Small Dents on a Car?

Small dents on a car body can be addressed in two scenarios: one where the paint has chipped off, and another where it hasn't. Dealing with dents where the paint has chipped is more complex compared to those without paint damage. It requires professional repair at a specialized auto body shop, where suction cups are first used to restore the car body, followed by touch-up painting, auto body repair, and other operations. For dents without paint damage, there are two methods: 1. Prepare a pot of hot water, pour it over the surface of the small dent, then use a toilet plunger to press against the dent area, repeatedly pulling it off with force; 2. Purchase a car dent repair kit online, which includes tools like a hot glue gun and a bridge-style suction puller. Use the suction cup to adhere to the car body, then apply pulling force to suction out the small dent on the body.

Can You Drive with Underinflated Tires?

Tires with insufficient air pressure can still be driven, but it is not recommended to continue driving. Underinflated tires will cause increased movement in various parts of the tire, leading to abnormal heating, which reduces the functionality of the cords and rubber, causing delamination or cord breakage. Excessive friction with the rim can also damage the bead area and cause abnormal wear. When tire pressure is insufficient, the sidewall undergoes more deformation during driving, generating excessive heat that may lead to tread separation or a blowout. You should drive to the nearest tire repair shop for assistance. While driving, as tire pressure drops, friction between the tire and the ground increases exponentially, causing a sharp rise in tire temperature, softening the tire, and drastically reducing its strength. Under these conditions, high-speed driving may result in a blowout.

What does the wrench icon in the car mean?

The wrench icon in the car is a maintenance reminder function set by the manufacturer to remind the owner to perform maintenance according to the specified mileage, indicating that the vehicle needs maintenance. When this light remains on for a long time, the owner should go to the 4S store for maintenance. Different car models from different companies have different maintenance intervals, which should be based on the vehicle's user manual. After the maintenance is completed, there is a reset procedure that requires resetting the maintenance light to zero. If not reset, the indicator light will remain on even after maintenance is performed. The maintenance cycle of the car is set at the time of production, and the small wrench icon will appear every certain number of kilometers to remind the driver to perform timely maintenance. Typically, the maintenance cycle is every 5,000 to 8,000 kilometers, and the original factory setting is usually more than 8,000 kilometers.

What Systems Make Up a Car?

The systems that make up a car: 1. Engine system: composed of the engine block group, crankshaft and connecting rod mechanism, valve train, fuel supply system, cooling system, lubrication system, ignition system, and starting system; 2. Chassis system: composed of the transmission system, running system, steering system, and braking system; 3. Electronic equipment system: includes the electronically controlled fuel injection system and ignition system, electronically controlled automatic transmission, anti-lock braking system, electronic traction control system, brake force distribution system, vehicle stability system, and torque distribution system. Cars are divided into: 1. Passenger cars: including standard passenger cars, convertible passenger cars, luxury passenger cars, compact passenger cars, and roadsters; 2. Commercial vehicles: designed and technically configured for transporting people and goods.

How to Remove Asphalt from a Car?

Methods for cleaning asphalt from a car: 1. Repeatedly apply car wax to remove the asphalt and tar stuck on the car body; 2. After wiping it off, use a clean cotton cloth to wipe the area again, which will thoroughly remove any residual tar stains from the car body. The principle is that the oil in the wax can dissolve the tar in the asphalt. If asphalt is still adhering to the car body, you can use a "tar remover" by evenly spraying it on the areas with asphalt and wiping with a cleaning cloth. This will quickly penetrate, dissolve, and remove stubborn stains such as tar, asphalt, and bird droppings from the car. However, this cleaner also has some corrosive properties, so be sure to rinse thoroughly after use.

Is the BMW 3 Series fuel consumption high?

BMW 3 Series fuel consumption is 8.0 liters per 100 kilometers, which is not very high. Reasons for increased fuel consumption: Using higher viscosity engine oil increases resistance during engine operation; prolonged warm-up can lead to more carbon deposits and the engine injects more fuel to maintain operation at low temperatures; frequent short-distance driving; carrying heavy items in the car for extended periods; low tire pressure; switching to wider tires. Impact of temperature on fuel consumption: Fluctuations in fuel consumption due to temperature changes are normal. Generally, in winter when temperatures are low, fuel consumption increases slightly, almost comparable to fuel consumption when using air conditioning in summer. This is because lower temperatures cause the engine to dissipate more heat. If the vehicle hasn't been serviced for a long time, dirty engine oil and air filters can also lead to increased fuel consumption.
