Minor cylinder scoring is easy to repair. Just replace the piston and piston rings, and lightly hone the cylinder walls. However, if the grooves reach 0.15mm, repair becomes impossible. For diesel engines, the cylinder liner can be replaced for repair. For gasoline engines, boring the cylinder and replacing the liner can be done for repair. After repair, there will be a break-in period, but the performance will be as good as new.

Will the insurance company compensate for water damage to the car?

To determine whether the insurance company will compensate for water damage to the car, you must first confirm if the vehicle has purchased comprehensive insurance (also known as collision insurance). Only then can you file a claim with the insurance company. The insurance company's staff will roughly assess the compensation situation based on the water level inside the car. The specific conditions are as follows: 1. The car is submerged to the highest level: If water reaches the central control screen, rendering the car unusable, it will be treated as a total loss. The insurance company will compensate based on the insured amount minus the residual value. 2. The car is submerged to the middle level: If left submerged for too long, the car may be declared a total loss as the electrical circuits will be damaged. If towed out promptly, it can be cleaned and repaired, and the insurance company will cover the repair costs. 3. The car is submerged to the lowest level: If water only reaches this level, cleaning and repairs are sufficient. It is best to have the repairs done at a 4S shop.

Can You Still Drive with Low Engine Coolant?

It is not advisable to continue driving when the engine coolant level is too low; it should be replenished promptly. The primary function of engine coolant is to maintain the operating engine within a normal temperature range. It cools the engine when it overheats and also provides antifreeze, anticorrosion, and anti-scaling effects. If the engine coolant level is low but still above the minimum mark, with some remaining in the reservoir, you can still drive. Although the coolant level is low, there is still enough coolant circulating in the cooling system, which won't significantly affect engine cooling. However, it should still be replenished as soon as possible. If the coolant level is so low that the reservoir is nearly empty, you must not drive. Continuing to operate the vehicle will cause the engine temperature to rise rapidly without adequate cooling, leading to potential engine damage. Regularly inspect the vehicle's cooling system and the remaining engine coolant level. If the coolant is found to be insufficient, it should be replenished immediately.
