How to Deal with Steering Wheel Lock and Push-Button Start Failure to Ignite?

The solution to steering wheel lock and push-button start failure to ignite is: 1. First, press the vehicle's brake pedal and gently press the push-button start once; 2. Wiggle the steering wheel left and right, then start the vehicle. When the car is turned off, rotating the steering wheel from the centered position to one direction (usually to the left) by a certain angle will lock the steering wheel.

Methods to avoid steering wheel lock include: 1. Straighten the steering wheel before turning off the engine; 2. Do not turn the steering wheel after turning off the engine.

Where is the car antifreeze generally located?

Car antifreeze is generally located in the car's radiator. The car radiator, also known as the heat exchanger, is a key component in the car's cooling system. Its function is to dissipate heat. The coolant absorbs heat in the water jacket, flows to the radiator where the heat is dissipated, and then returns to the water jacket to circulate and regulate temperature. It is an integral part of the car engine. Antifreeze prevents the coolant from freezing during cold winter parking, which could otherwise crack the radiator or damage the engine cylinder block. Its full name is antifreeze coolant. Antifreeze is a type of coolant containing special additives, primarily used in liquid-cooled engine cooling systems. It offers excellent performance in preventing freezing in winter, boiling in summer, and protecting against scale and corrosion year-round.

Does the salvage value of a total loss vehicle belong to the owner or the insurance company?

In general, the salvage value of a total loss vehicle belongs to the insurance company; otherwise, the insurance company will deduct the salvage value when compensating. The insurer obtains ownership of the insured vehicle's salvage value under the following two circumstances: In the case of full insurance: After the insurance incident occurs, the insurer pays the full insurance amount, and the entire value of the damaged insured property belongs to the insurer. In the case of insufficient insurance amount: When the insurance amount is lower than the insurance value, the insurer obtains partial rights to the damaged insured property based on the ratio of the insurance amount to the insurance value. Therefore, it is reasonable for the insurance company to assign the salvage value to the vehicle owner. However, if the owner disputes the amount of the salvage value, they can negotiate with the insurance company.
