(Baonghean.vn) - In hot weather, many car owners try to find ways to "cool down" their cars. However, if you do not take care of and do it properly, you will waste money and damage your car.

1. Wash your car immediately after a long drive.

Feeling sorry for their car after having to endure a hot day or a long drive, many car owners often wash their car as soon as they get home to cool it down and remove dirt and sand. However, car experts do not recommend this method.

The reason is that when the car has just turned off, the metal cells on the car body are still in a state of expansion due to high heat and will suddenly contract due to low heat. This situation is not good for the car because it causes brittleness, rust and easy breakage for small machine parts.

2. Turn on the air conditioner at full power immediately after starting the machine.

In fact, this is an extremely dangerous habit for both the user and the engine... When the engine is first turned on, the engine is still at a very low rpm range, turning on the air conditioner at maximum capacity will create a lot of pressure on the engine. In the long run, the engine will lose performance, wear out machine parts, generate unpleasant sounds when operating; or more seriously, the engine cannot continue to operate...

In addition, turning on the air conditioner right after getting in the car is also harmful to the driver's health. Because when the body is in a state of sweating due to heat, if suddenly exposed to cold, it will reduce blood pressure, causing heat shock and heatstroke in weak people.

Therefore, it is best to roll down the windows and turn on the fan after getting in the car to push the hot air out of the car, then turn on the air conditioning (A/C) a while later.

3. Change coolant and oil more often

In hot weather, coolant and engine oil are also consumed more; however, car owners do not need to regularly add coolant and engine oil to the car's engine system because it is wasteful and unnecessary.

According to the manufacturers' recommendations, drivers should only add coolant and change engine oil periodically based on the distance the vehicle has traveled (for example, 5,000km, 10,000km, etc.). In addition, car owners can check the coolant and oil tank every 2 months if the vehicle is driven a lot and every 3 months if it is driven less. If the coolant is low and the oil has a lot of black residue, it is necessary to add more.

4. Shorten the interval between maintenance

Many drivers believe that doing so is better for their car because on hot days the car will be under more pressure than usual. However, this is really unnecessary and wasteful.

Users do not need to shorten the vehicle maintenance intervals, just need to periodically take the vehicle for inspection according to the standard mileage as instructed by the vehicle manufacturer. In addition, maintaining the vehicle too often also has certain harmful effects because if you often remove and install the screws that fix the threaded ring, it will easily wear out, causing the vehicle to make strange noises when operating.

5. In summer, you need to use a larger battery.

With the notion that in the summer, we need to use more air conditioning, the engine's power is not enough, so we need a larger battery; car owners have inadvertently broken the voltage balance in the car's mechanical system.

In fact, the responsibility of providing electricity to start the car belongs to the generator. Therefore, the battery does not have to bear the large capacity as many people think and the car owner can completely use the original battery of the car without having to replace it with a type with a higher voltage.
