What Causes Engine Overheating and Loss of Coolant?

Do You Need to Add Antifreeze in Summer?

You need to add antifreeze in summer. Antifreeze is a type of coolant containing special additives, mainly used in liquid-cooled engine cooling systems. It has excellent properties such as preventing freezing in winter, boiling in summer, and resisting scale and corrosion throughout the year. Composition of Antifreeze: The main components of antifreeze are: 50% pure water, 40% methanol, and 10% other substances. Types of Antifreeze: Antifreeze is generally divided into three types: ethanol-water, glycerol-water, and ethylene glycol-water. Can Different Antifreeze Brands Be Mixed? You must use the same brand of antifreeze. Different brands of antifreeze may have varying production formulas, and mixing them could cause chemical reactions between additives, rendering them ineffective. How to Choose Antifreeze: The basic indicators of antifreeze are freezing point and boiling point. The market offers antifreeze with freezing points of -15°C, -25°C, -30°C, -40°C, etc. Generally, it is advisable to choose one that is at least 10°C lower than the lowest temperature in your region.

How to Turn on the Car Defroster?

Car defroster switch: The front windshield defroster is represented by a fan-shaped pattern with three upward lines, and the rear windshield defroster is represented by a rectangular pattern with three upward lines. Press the corresponding button to activate it. Below is an introduction to the defroster: 1. The function of the defroster is to capture mist particles and slurry droplets carried by the flue gas during the spray absorption process. 2. The defroster mainly consists of plates and a support device. The plates are usually made of two types of materials: polymer materials (such as polypropylene PP, FRP, etc.) or stainless steel (such as 316L, 317L, etc.). They are generally divided into streamlined and folded types.

Why Do Turbocharged Engines Use 95 Octane Fuel?

Turbocharged engines use 95 octane fuel due to its excellent anti-knock properties. Here are the extended details: 1. High-octane fuel has a higher ignition point and better anti-knock performance, allowing for increased pressure in the engine cylinders, resulting in greater explosive recoil force and improved engine output power. 2. 95 octane fuel has a higher ignition point, slower combustion speed, and higher heat release, enabling it to meet the varying power demands of different engines. 3. The cylinder volume of a car engine remains constant. With an engine compression ratio of 11:1, meaning 11 volumes of air are compressed into 1 unit volume in the cylinder, the turbo starts working when the car is started, and the engine draws in air. 95 octane fuel can withstand higher pressure without causing knocking issues.

What is the Principle of Car Remote Door Locks?

The basic principle of car remote keys: A weak radio wave is emitted from the vicinity of the car owner, which is received by the car's antenna. The electronic control unit (ECU) then identifies the signal code, and the system's actuator (motor or electromagnetic coil) executes the lock/unlock action. Below is a detailed introduction: 1. The system mainly consists of two parts: the transmitter and the receiver. 2. Transmitter: Composed of a transmission switch, transmission antenna (keypad), integrated circuit, etc. 3. Receiver: After the transmitter sends the identification code via shortwave modulation, it is received by the car's shortwave antenna and processed through a distributor into the shortwave high-frequency amplification processor of the receiver's electronic control unit for demodulation.

What to Do When the Car Has Power but Won't Start?

When the car has power but won't start, it's usually due to a fault in the CU or control circuit. Here are some extended troubleshooting steps: 1. If the battery has sufficient charge, check the starter's fuse and relay. 2. The issue may be caused by poor contact in the starter solenoid coil - try gently tapping it with a short metal pipe. 3. If the car key won't turn and the steering wheel is locked, this prevents vehicle starting. 4. There might be poor contact in the throttle wiring - check the thin red or green wires inside the thicker black wire running from the handlebar to the controller (the thin black wire should be fine).

What Are the Impacts of a Dead Car Battery?

A dead car battery most directly affects the vehicle by preventing it from starting and rendering the anti-theft system inoperable. Here are the specific details: 1. Normal engine startup requires spark, gasoline, air, and the starter motor to turn the engine. If the battery is dead, there will be no electricity in the high-voltage coil, preventing the spark plugs from igniting properly. Additionally, the fuel pump cannot operate without power, cutting off the fuel supply. The starter motor also fails to turn when the battery is dead. Therefore, the engine cannot start at all when the battery is depleted. 2. The anti-theft system relies on power to function. Without battery power, the anti-theft system cannot operate normally.
