The method for adding coolant and its operational steps are as follows: 1. Tighten the radiator drain switch and fill the radiator with coolant until it overflows. 2. Tighten the radiator filler cap. 3. Fill the engine coolant into the reservoir until the liquid level reaches the full level line. 4. Warm up the engine until the thermostat valve opens. 5. Wait for the coolant to cool down. 6. Remove the radiator filler cap and check the coolant level. Relevant information about coolant is as follows: 1. The full name of coolant is antifreeze coolant. It prevents the engine from freezing in winter and cools the engine when it generates high temperatures during operation, ensuring the vehicle can work normally in various environments. 2. The powerful effects of coolant are composed of various chemical components. Coolant is poured from the reservoir. Front-engine family cars generally require about 3-4 liters of coolant, while for mid-engine or rear-engine cars, since they still need a radiator located at the front of the car to dissipate heat for the cooling system, due to the overall layout, these cars require at least twice the amount of coolant compared to front-engine cars.

I'm quite familiar with the coolant refill method because my car often has this issue. First, ensure the engine is completely cooled—never operate when the car is hot; wait overnight or after the car has been cold for several hours. Open the engine hood and locate the coolant expansion tank, usually a transparent plastic container, and clearly identify the maximum and minimum level marks. If the fluid level is below the minimum, prepare the same type of coolant—avoid mixing different brands as it can cause sedimentation or corrosion issues. Slowly unscrew the cap and pour the coolant into the expansion tank gently to prevent air bubbles. After filling, tighten the cap, start the engine, and let it idle for a few minutes. Then turn it off and check if the fluid level stabilizes. If it's low, top it up until it stays in the middle range. Remember to clean any spilled liquid and check for leaks, as leaks could indicate a faulty water pump or hose. Regularly check the antifreeze every six months—don't wait for a warning light. Pay extra attention to the replacement ratio during seasonal changes.

I'm a safety-conscious person, so I always take extra care when adding coolant. Make sure the car has been turned off for several hours to cool down, avoiding burns from high temperatures. Wear gloves and protective goggles, locate the expansion tank, usually positioned in the middle or side of the front engine bay. Use a cloth to clean the dust around the cap to prevent impurities from entering the system. Choose the correct coolant color and type—don’t mix green, red, or blue to avoid chemical reactions that could damage the engine. Pour the coolant steadily into the expansion tank without overfilling; the level should stay between the maximum marks. After completing the task, start the engine and let it idle for three to five minutes to allow the coolant to circulate. Then, turn off the engine and recheck the coolant level. Finally, inspect the hoses and connections to ensure they are secure and leak-free, preventing future malfunctions. Regular checks are a good habit, especially before long trips—safety comes first.

What Causes the Resonance Hum in the Cab?

The possible causes of resonance hum in the cab are as follows: 1. Whole vehicle resonance caused by the front axle: Excessive unbalance in brake drums or wheel hubs; Out-of-round brake drums. 2. Whole vehicle resonance caused by the rear (middle) axle: Out-of-round brake drums. 3. Whole vehicle resonance caused by engine mounts: Low bracket stiffness with significant elastic deformation; High hardness of mount cushions with large dynamic and static stiffness. 4. Whole vehicle resonance caused by the engine itself: Uneven fuel injection among engine cylinders, leading to incomplete combustion or non-operation in some cylinders; Large manufacturing tolerances of parts, with excessive unbalance in pistons, connecting rods, crankshaft flywheels, etc. 5. Whole vehicle resonance caused by the suspension system: Unreasonable matching of vibration frequencies between front and rear suspensions; Coupling of front spring natural frequency with the frame's inherent frequency.

What to Do When the Car Still Rolls After Engaging the Handbrake?

Solutions for when the car still rolls after engaging the handbrake: Tighten the handbrake cable. For manual transmission vehicles, you can press the clutch with your left foot, press the brake with your right foot, engage any forward gear, pull the handbrake, and then turn off the engine, using the gear's traction to prevent rolling. For automatic transmission vehicles, press the brake, shift to P (Park), engage the handbrake, and turn off the engine, utilizing the automatic transmission's P gear lock to prevent further rolling. More details are as follows: 1. If the handbrake suddenly fails or doesn't hold during normal use, it can be very dangerous, especially on steep slopes where sudden failure poses a greater risk. 2. Automatic transmission models are easier to operate; when in a forward gear, pressing the brake prevents rolling, and releasing the brake while quickly applying the throttle ensures the power is sufficient to move the vehicle forward.

Does the C2 have a clutch?

C2 does not have a clutch. Here is some extended information: 1. The difference between C1 and C2: A C2 driver's license only allows driving small and micro automatic passenger vehicles, as well as light and micro automatic cargo vehicles; A C1 driver's license permits driving small and micro passenger vehicles, light and micro cargo vehicles, light and micro special operation vehicles, low-speed cargo vehicles, and three-wheeled vehicles. Moreover, the cost of obtaining a C1 license is cheaper. In summary, holders of a C1 license can drive automatic vehicles covered by a C2 license, but C2 license holders cannot drive manual vehicles covered by a C1 license. The C1 license allows driving a wider range of vehicle types. 2. The benefits of C2: Although the test subjects and procedures remain the same whether you are obtaining a C1 or C2 license, there are certain advantages due to the structural differences in the vehicles driven. Since automatic vehicles do not have a clutch pedal and do not require gear shifting, there is no need to worry about stalling the engine.

What is the difference between AT and CVT

AT and CVT differ in the following aspects: 1. Principle: AT works by using a torque converter whose automatic shifting and torque variation range is insufficient, so several rows of planetary gears are connected in series behind the turbine to improve efficiency. The hydraulic control system automatically operates the planetary gears according to the engine's working changes, achieving automatic shifting and torque variation. CVT's transmission pulley structure is quite unique, divided into movable left and right halves that can move closer or apart. The conical discs can tighten or expand under hydraulic thrust, squeezing the steel belt chain to adjust the width of the V-shaped groove. When the conical discs move inward to tighten, the steel belt chain is pushed outward from the center, and vice versa. This changes the diameter of the disc driven by the steel belt chain, altering the transmission ratio. 2. Usage: AT does not require clutch shifting, has fewer gears but significant changes, and connects smoothly, making it easy to operate. It provides convenience for the driver and comfort for passengers. CVT, lacking the transmission gears of a typical automatic transmission, eliminates the shifting process and the associated jerky sensation. Therefore, CVT transmissions deliver linear power output, offering a very smooth driving experience.

What is the normal high pressure for a car air conditioner?

The normal high pressure for a car air conditioner should be 1.3-1.7MPa (13-17kg/cm2 or 190-250Lbf/in2); the normal low pressure should be between 0.15-0.25MPa (1.5-2.5kg/cm2 or 20-35Lbf/in2). 1. Car air conditioning system: The car air conditioning system is a device that cools, heats, ventilates, and purifies the air inside the vehicle. It provides a comfortable environment for passengers, reduces driver fatigue, and improves driving safety. The air conditioning system has become one of the indicators of a car's functionality. 2. Disadvantages of car air conditioning: When the air conditioner is turned on, it is best for passengers not to smoke in the car. Since the air inside the vehicle circulates in a relatively enclosed environment when the air conditioner is on, first, the smoke is not easily dispersed, and second, the tiny particles in the smoke can adhere to the air intake filter of the air conditioner, causing long-lasting odors in the car. Regular professional cleaning and deodorizing maintenance of the air conditioning system is recommended.
