Large decoration shops can handle it, but it's usually more expensive. There are also simpler methods, such as applying a dashboard film or using a dashboard protective mat. If your car's dashboard is warping, you can drive it to an auto repair shop or contact after-sales service to replace the dashboard for a fee. When replacing the dashboard, choose one that matches your car model and is of higher quality, ensuring the outer plastic is resistant to melting and deformation.

I just encountered a dashboard crack issue and did a DIY repair that turned out okay. A cracked plastic car dashboard is most commonly caused by sun exposure aging or impact. For the repair, first thoroughly clean the crack to ensure no dust or grease remains; then slowly fill the crack with plastic-specific adhesive, using a tool to flatten it and avoid bubbles; after the adhesive dries, sand it smooth with fine sandpaper. For larger damages, there are plastic repair patches available online—cut small pieces to stick on. Finally, apply some automotive paint to match the color. The whole process requires patience, taking about one to two hours with materials costing just a few dozen yuan. When parking, use sunshades to prevent prolonged sun exposure.

What are the main types of car insurance to purchase?

Vehicles generally require compulsory traffic insurance and commercial insurance. Commercial insurance includes vehicle damage insurance, third-party liability insurance, and no-deductible coverage. Below are the relevant details: 1. Compulsory Traffic Insurance and Vehicle Tax: This is the minimum standard insurance required for a vehicle to be legally driven on the road, and it is mandatory by the state. It is not collected by insurance companies. Its coverage includes any losses caused to a third party (excluding the insured vehicle and its passengers), regardless of fault, with a maximum compensation amount of 2,000 yuan. 2. Vehicle Damage Insurance: This is the most basic coverage to protect your own vehicle from damage. For example, accidents like hitting a utility pole or hail damaging the car, as well as losses caused by natural disasters, are covered under vehicle damage insurance. However, it is important to note that losses caused by earthquakes are not covered by insurance companies. 3. Third-Party Liability Insurance: This is arguably the most worthwhile insurance to purchase for a vehicle. If you are fully at fault, such as damaging someone else's car or accidentally hitting a pedestrian, the resulting vehicle repair costs and medical expenses for the injured party are all covered by third-party liability insurance. 4. No-Deductible Coverage: By purchasing this coverage, you can transfer the 5% to 20% of the liability that would normally be your responsibility to the insurance company in the event of an accident. However, no-deductible coverage can only be purchased as an add-on to a 'primary insurance' and cannot be bought separately.

How Many Liters of Engine Oil Does the CIIMO Need?

CIIMO requires four liters of engine oil. Around four liters is the most reasonable amount. Functions of Engine Oil: Shock absorption and cushioning: When the pressure in the engine cylinder rises sharply, it suddenly increases the load on the piston, piston pin, connecting rod, and crankshaft bearings. This load is transmitted and lubricated through the bearings, providing a cushioning effect against the impact load. Considerations When Purchasing Engine Oil: When selecting engine oil, the correct oil grade is the primary factor to consider. To choose the right oil product for your vehicle from the numerous options available, it's essential to understand the classification methods for automotive engine oil grades. Proper selection and addition of additives can improve physical and chemical properties, impart new special characteristics to the lubricant, or enhance its existing properties to meet higher demands.
