Why Should You Avoid Restarting a Flooded Car?

Restarting a stalled vehicle in water is considered a secondary ignition attempt, which can damage the engine. Here are precautions for driving through flooded road sections: 1. Assess water conditions: Pay attention to water depth. Observe other vehicles currently crossing to determine if your vehicle can pass safely based on their water levels and positions. 2. Check road surface conditions: Judge shallow areas and pothole-free zones by watching preceding vehicles. If no vehicles have crossed, always exit to personally verify conditions before proceeding. 3. Driving through water: Maintain low speed. For manual transmission vehicles, use second or third gear depending on water depth; shift to first gear in deep water with heavy traffic. 4. Avoid hard acceleration: Aggressive throttle application is highly inadvisable. Many drivers fear stalling and accelerate abruptly, often creating more serious problems.

Take out the old battery and replace it with a new one; 5. Assemble the key.

What Causes High Temperature in Cars During Summer?

High temperature in cars is caused by the radiator fan not rotating, poor radiator heat dissipation, and insufficient coolant. The details are as follows: Radiator fan not rotating: The simplest way to check if the radiator fan is functioning properly is to turn on the vehicle's air conditioning cooling system. If the air conditioning compressor is running but the fan is still not rotating, then the fan must be faulty. Poor radiator heat dissipation: This situation often occurs during April and May when there is a lot of willow catkins and cotton fluff. To check, simply open the engine hood and observe if there is excessive debris in the radiator located behind the bumper. If the radiator is severely clogged, it needs to be cleaned at a repair shop. Insufficient coolant: This is a relatively easy condition to observe. Just open the engine compartment and check if the coolant level meets the requirements. Poor water pump performance: The water pump belt may sometimes slip or idle due to prolonged use. When this problem occurs, the main characteristic is that it returns to normal after pressing the accelerator and maintaining it for a while.
