Can You Still Drive When the Coolant Level is Below Min?

You can still drive for a short period when the coolant level is below min, but prolonged driving is not recommended. A coolant level below min indicates insufficient coolant, which needs to be replenished promptly. Continuing to drive for an extended period may cause harm to the engine. If the coolant level is below min and you drive for a long time, it can affect the radiator's cooling efficiency, leading to engine overheating and, in severe cases, engine damage. The full name of coolant is antifreeze coolant, which means it is a cooling liquid with antifreeze properties. It prevents the coolant from freezing and expanding in cold winter conditions, which could otherwise crack the radiator or damage the engine cylinder block or head. Coolant is a specially formulated liquid with additives that provide excellent performance in preventing freezing in winter, boiling in summer, and protecting against scale and corrosion year-round.

What Causes the Thumping Noise When Driving on Uneven Roads?

Uneven road surfaces causing thumping noises in the vehicle may indicate a malfunction in the shock absorber or the shock absorber top mount. The connection points between shock absorbers and the vehicle body are equipped with buffer rubber mounts, which are rubber components. Over time, these rubber parts can age and harden, leading to abnormal noises when the car traverses bumpy roads. The solution is to replace the buffer rubber mounts. If the shock absorber itself is damaged, it will also produce abnormal noises when driving over uneven surfaces, requiring replacement with a new shock absorber. As the core component of the vehicle's vibration filtration system, shock absorbers primarily absorb vibrations and impacts generated by uneven road surfaces during driving, ensuring a comfortable ride for passengers.

Will the 4S shop still be responsible if problems occur after maintenance outside?

The 4S shop will continue to be responsible if the car is still under warranty. However, it should be noted that the problematic part cannot be the one that was maintained outside. For example: if the engine and transmission were maintained outside and the car battery fails, the 4S shop should be responsible for it. But if the faulty part is the one maintained at an external repair shop, the 4S shop cannot be held responsible. Below is the significance of maintenance: 1. Regular maintenance can extend the service life of the car and reduce the failure rate. Maintenance items include the vehicle's fluids and consumable parts, which need to be replaced. 2. Long-term lack of car maintenance can lead to severe carbon deposits and greatly threaten the safety of the engine. Once it occurs, it can cause the engine to fail to work properly.
