No, it's not okay. At this point, the engine may already be damaged, or it may not be damaged. In most cases, it is not damaged, but if you attempt to restart the engine after stalling, it will definitely cause damage to the engine. Here is the relevant explanation: Reason: Because the engine's intake system has sucked in water. The engine's intake suction is very strong, and water will be drawn into the cylinders through the intake pipes. Since water is being sucked in instead of air, the engine cannot combust properly and stalls. Water entering the cylinders cannot be compressed. When the piston moves upward, the upper space of the cylinder is occupied by water, but the piston continues to push upward, causing the connecting rod to bend. A bent connecting rod is irreversible severe damage and requires an engine overhaul. Consequences: The damage caused by attempting to restart after stalling in water is very significant, and insurance companies will not cover the losses resulting from such actions.

Where to Check the Production Date of Tires?

The production date of a tire is indicated by a four-digit number, which is marked on the sidewall of the tire. The first two digits represent the production week, and the last two digits indicate the year. For example, the number 1019 means the tire was produced in the 10th week of 2019. Here is some relevant information about tires: 1. When purchasing tires, always check the production date: Avoid buying tires with production dates that are too old. Tires are rubber products and will age even if not used. 2. Regularly inspect tire pressure and the surface for any damage during daily use: The sidewall of a tire is relatively fragile, and if it gets scratched or punctured, it cannot be repaired. It is recommended that car owners replace their tires every four years, even if the mileage driven within those four years is low.
