Are Antifreeze and Coolant the Same Thing?

Antifreeze and coolant are not exactly the same. Below are the differences between coolant and antifreeze: 1. Antifreeze is not entirely equivalent to coolant. Coolant is equal to water plus antifreeze. Water is a very low-grade coolant and is also subject to seasonal limitations, meaning antifreeze includes coolant, but coolant does not include antifreeze. 2. Typically, engine coolant (antifreeze) needs to be replaced every two to three years. If you choose a higher-quality coolant and there are no leaks in the engine cooling system, the replacement interval can be extended. When you notice a shortage of coolant, take it to a professional shop to test with a refractometer. If the freezing point of the coolant remains below -30°C, replacement is unnecessary. When replacing antifreeze, ensure it is completely drained, and avoid mixing it with water or other brands of antifreeze. 3. The boiling point of pure water under normal temperature and pressure is 100°C. Once the engine temperature becomes too high, the cooling water will boil and turn into steam. The heat convection coefficient of water in a gaseous state is much lower than in a liquid state, so gaseous steam can hardly dissipate the engine's heat. The components in antifreeze help cool the engine, thereby preventing issues like overheating to a certain extent.

Can Halogen Lights Be Directly Replaced with LED?

Halogen lights can be directly replaced with LED. To replace halogen lights with LED lights, the entire LED light assembly needs to be replaced. Simply changing the bulb alone is not effective. If the original vehicle does not have a lens, it is not recommended to modify the lights. After modification, not only will the effect be minimal, but it may also cause glare for the driver, impairing visibility and posing significant safety hazards. The following precautions should be noted when replacing halogen lights with LED lights: 1. After changing the headlights, it is necessary to apply for motor vehicle modification registration at the vehicle management office in accordance with regulations. 2. When modifying the lights, pay attention to the various parameters of the lights, which should strictly comply with relevant national regulations. 3. LED lights are not focused, so a lens needs to be installed for focusing.

Can the Exhaust Brake Be Used for a Long Time?

Exhaust brake cannot be used for a long time. Below is detailed information about exhaust braking: Exhaust braking is also a braking method for large trucks when going down long slopes, but it should not be used for extended periods, as it can cause significant damage to the engine, especially affecting the valves. It is recommended to use it with intervals of about 5 seconds each time. Its working principle involves using a shut-off valve to close the exhaust, creating a rapid increase in local air pressure within a small space, thereby reducing the engine speed to achieve the braking effect. For vehicles equipped with a hydraulic retarder, which offers excellent performance at both low and high speeds, it can handle the vast majority of long gentle slopes without needing to be used in parallel with the main braking system, except for extremely steep slopes. It can also be used in conjunction with the exhaust brake. On ordinary gentle slopes, intermittent braking can be used to protect the brake pads from overheating, which could lead to reduced braking efficiency or even failure.
