How to handle when a car engine is too hot

There are several causes of car engine overheating such as lack of cooling water, leaks … that you should know to fix quickly, avoid causing serious damage to the car.

1. What to do when stopping the car

Step 1: Stop the car. As soon as detecting that the engine temperature pointer turns to the letter H (short for Hot: hot), the driver should find a way to immediately hit the curb to safely stop the car, turn off the engine to cool the engine. For hot days should pay more attention to the temperature mark. If you see steam rising from the bonnet, stop immediately.

Step 2: Open the hood. Open the hood to allow room for engine heat to escape more quickly. Some cars have bonnet latches near the radiator, so drivers need to be careful, lining their hands before opening the lid to ensure safety.

Step 3: Do not open the radiator cover. It is a taboo that all drivers need to pay attention not to open the radiator cap right now because high temperature makes the pressure of the water in the tank very large, when opening the lid, water can erupt and cause burns.

Step 4: Check the cooling water level.

  • After you wait for the engine and cooling system to cool down, open the radiator cover to check it. Most vehicles have a water tank to lead into the water tank, which can be seen with the naked eye whether the water level is full or not.

  • If the vehicle has a tank, fill the amount of coolant, if in emergency there is no coolant, replace it with clean water.

  • If the vehicle does not have a tank, it is imperative to wait for the cooling system to cool completely before opening the lid to add solution or water.

Step 5: Look for leaks. There are many cases where the car overheats because the cooling system leaks in the pipes, the cylinder head or the foil in the radiator due to the kick … If it is impossible to check or take the car to a repair shop nearest to a technician.

Step 6: If the vehicle simply lacks cooling water and refills it, you can go on, but if the car is dry, the cool water is empty for unknown cause, it’s best to call for rescue.

2. How to handle when forced to continue driving

Step 1: Turn off harmonic. Air-conditioning system works, causing the engine to overload, leading to rapid heat.

Step 2: Switch to hot mode. Turn heating on fully, turn on the fan to maximum. If it is hot, turn the vents out to the windows, and lower the glass so that the hot air can escape. Because this system uses engine heat to heat the air in the car, the more it escapes, the faster the engine cools.

Step 3: Doesn’t move much. Once in a hot engine state, do not move for as long as a normal vehicle. Instead, the frequency of resting will be more.

Step 4: Turn off the engine but do not turn off the power. Turning the key to turn off the engine but not turning off the electrical system completely, so that the heater continues to work, will release hot air from the engine faster.

Step 5: Go at a moderate speed. Don’t go fast, stop, fast, stop, but go slowly at a moderate speed. Acceleration increases the load, making the engine hotter faster.

Step 6: Use tips.

  • If your vehicle uses a belt-driven radiator fan (usually rear-wheel drive or 4-wheel drive), take the following method after stopping at a red light. Push the gear lever to N or P (automatic transmission), lightly depress the gas pedal to go up to about 2,000 rpm, keep the accelerator at that threshold for about a minute. This way the fan rotates faster, releasing less hot air.

  • But for cars with electronic radiator fans (usually front-wheel drive vehicles), this approach doesn’t work.

Step 7: If possible, wait for the road to clear up. The car is hot and moving into the crowded road only makes things worse because the travel time is longer and the cool breeze cannot be used. So, if possible, pull over and wait until the traffic stops.
