How Long Does It Generally Take to Repair a Rear-End Collision?

In cases where the rear-end collision is not severe, bodywork and painting typically take 2-5 working days. If the main frame is damaged, the repair may require 10-30 working days.

Below are the steps for handling a vehicle rear-end collision: Visually Assess the Damage: After a collision, you can first visually assess the extent of the damage.

Inspection and Damage Assessment: After a collision, you should contact your vehicle insurance provider. An insurance assessor will then conduct an on-site inspection, taking photographs of the exterior damage. It is crucial to preserve the accident scene during this process.

What Causes High Water Temperature When Heavy Vehicles Climb Slopes?

There are several main reasons for high water temperature when a vehicle climbs slopes: High temperature gauge reading: When traffic is congested or the vehicle idles for a long time, the engine temperature gauge shows a high reading, the electronic fan operates at high speed for too long, engine noise increases, and the issue is most noticeable when using the air conditioning in hot weather. Unstable idling: When using the air conditioning in hot weather, the idling is unstable with significant RPM fluctuations, the vehicle lacks power during sudden acceleration, and the engine produces abnormal noises. Engine stalling while driving: The vehicle may be difficult to start again after stalling for more than ten minutes. Sometimes, the engine may stall automatically while driving when the vehicle is hot. Poor cooling performance: The air conditioning cools effectively when the engine is cold, but the cooling performance deteriorates when the engine is hot. Additionally, there is noticeable resonance and humming noise in the air conditioning system.

What is the reason why the key can keep turning but cannot unlock?

The reasons why the key can keep turning but cannot unlock include: wrong direction, rusted lock cylinder, or key issues. Wrong direction: When the mechanical key is rotated in the wrong direction, the car door will not unlock. In most cases, the rotation direction to unlock the car door is clockwise, while the opposite direction locks it. If you are unsure about the unlocking direction, you can refer to the car's user manual for guidance. Rusted lock cylinder: Most car owners use remote keys to unlock or lock the car door and rarely use mechanical keys. As a result, the lock hole may rust due to prolonged disuse. In such cases, you can try lubricating it with engine oil. If it still doesn't work, the lock cylinder may need to be replaced. Key issues: In most cases, mechanical keys do not have significant problems. If there is an issue, it is usually with a later-made duplicate key that is incomplete. Sometimes, in the early morning during winter, the mechanical key may not turn when trying to unlock the car door. This is caused by residual water from car washing entering the keyhole. When the key is inserted, the locking mechanism inside fails to pop up, preventing the key from turning. In such situations, avoid applying excessive force to turn the key, as it may cause damage or deformation, rendering the key unusable.
