Normal Freon Level: When the air conditioning is running normally and continuously, there are no bubbles in the sight glass. When the air conditioning stops, brief bubbles appear. 2. Insufficient Freon: When the air conditioning is running normally and continuously, there are continuous bubbles in the sight glass, indicating insufficient Freon, which needs to be replenished. 3.

When starting a car, should you release the handbrake first or shift into gear first?

When starting a car, you should first shift into gear and then release the handbrake, mainly for safety reasons. This is because when starting, you may not know if the ground is level. If the ground is sloped and you release the handbrake first, the car will be in a neutral coasting state, causing the vehicle to roll in the direction of the slope without any braking, which can easily lead to a safety accident. The sequence when parking is the opposite of starting. When parking, you should first engage the handbrake and then shift into neutral. This ensures the vehicle does not move to the greatest extent possible. This is because many people are accustomed to releasing the clutch and brake after shifting into neutral. If the gear is not correctly shifted into neutral or the parking spot is on a slope, the vehicle may move. However, for automatic transmission cars, when parking, you can directly shift into P (Park) and then engage the handbrake.

What is the normal tire pressure for cars?

There are specified values for car tire pressure. For passenger cars, the standard tire pressure is within the range of 2.3-2.5 bar, with a maximum not exceeding 3.0 bar and a minimum not below 2.1 bar. According to the international GBT2978-2008 standard, the tire pressure for different types of tires is as follows: Standard tires: 2.4-2.5 bar; Reinforced tires: 2.8-2.9 bar; The maximum pressure should not exceed 3.5 bar. Normal tire pressure in winter: In winter, the tire pressure should be based on the standard tire pressure of the car tires, with an appropriate increase of about 0.2 bar. Normal tire pressure in summer: Generally, the lower limit of the standard tire pressure for car tires is sufficient. For example, the lower limit for standard tires is 2.4 bar. If the car is often parked outdoors, the tire pressure can generally be about 0.1 bar lower than the standard to avoid tire blowouts due to high temperatures.
