Coolant warning indicates insufficient coolant level in the vehicle, or it may signal an alert for excessive radiator temperature. Continuing to drive under these conditions is not advisable. Persistent operation may cause escalating engine temperatures, potentially leading to engine damage. To prevent unnecessary losses, it's recommended to immediately pull over to the emergency lane, activate hazard lights, place warning triangles, and await roadside assistance. Below are key points about coolant: 1. The primary function of engine coolant is to maintain proper engine operation by circulating through the radiator, providing anti-freeze, anti-boil, anti-rust, and anti-corrosion protection. Most coolants appear red or green for leak detection and to distinguish them from other engine fluids. 2. Engine coolant should be replaced according to mileage or time intervals, as visual inspection cannot accurately determine its degradation. Deteriorated coolant with reduced anti-corrosion properties may damage radiators, pipes, and hoses. 3. Always measure antifreeze freezing point; prevent leaks and hot coolant spray during replacement. Ensure complete drainage of old coolant (from both radiator and engine block); maintain proper fill levels; eliminate residual leaks on components; verify system integrity post-service.

How to Tell if the Throttle Body is Dirty?

The most obvious signs of a dirty throttle body are insufficient engine power, shaking or even stalling at idle, and unresponsive acceleration when pressing the gas pedal. Regularly cleaning the throttle body can reduce fuel consumption, improve fuel efficiency, and extend the engine's lifespan. More details are as follows: 1. The throttle body is a controllable valve that regulates air intake into the engine. After entering the intake pipe, the air mixes with gasoline to form a combustible mixture, which then burns to generate power. The throttle body is one of the most critical components in modern fuel-injected engine systems. Its upper part connects to the air filter, while the lower part links to the engine block, essentially serving as the 'throat' of the car engine. 2. When the throttle body becomes dirty, it directly affects the precision and smoothness of engine air intake. The most noticeable symptoms include reduced engine power, sluggish acceleration (with the gas pedal feeling stiff or sticky), delayed RPM response when pressing the throttle at idle, and an immediate drop in speed upon releasing the pedal. In severe cases, the engine may shake violently or even stall. These signs indicate that the throttle body needs cleaning. 3. The vehicle's acceleration responsiveness and fuel consumption are closely tied to throttle body cleanliness. Cleaning the throttle body can lower fuel consumption and restore the engine's agility and power. Regular throttle body maintenance helps reduce fuel usage, enhance fuel efficiency, and prolong the engine's lifespan.

What does replacing the PCV valve mean?

PCV stands for Positive Crankcase Ventilation, which refers to the positive ventilation control system for the crankcase (or oil pan). The PCV valve consists of a valve body, valve, valve cover, and spring, and is non-disassemblable. Its main functions are: to direct gases from the crankcase into the intake manifold via the PCV valve, with a small amount of air entering the intake manifold directly from the air filter through the PCV valve. This prevents icing at the throttle, incomplete combustion, and worsening emissions. It also prevents exhaust gases from entering the atmosphere and keeps the engine oil from deteriorating. At the end of the engine's power stroke, some unburned mixture leaks into the crankcase under high pressure through the piston rings, a phenomenon known in the industry as 'blow-by.'

What Level of Wind Can Blow a Car Away?

Details are as follows: 1. The weight, shape, and wind-exposed area of the car: Generally, sedans have stronger resistance to typhoons compared to SUVs. This is because sedans have a lower center of gravity, are much shorter in height than SUVs, and have stronger grip on the road. 2. The ability to resist typhoons differs between moving and stationary cars: A moving car is in a state of motion. According to the physics relationship between moving objects and wind force, a moving car's ability to resist typhoons is much weaker than that of a stationary car. Generally, a stationary car can withstand a typhoon of level 14, while a moving car may lose control of its direction under a level 12 typhoon, especially when the typhoon blows from the side, making the car prone to rollover accidents.

How to Fix Air Leakage from the Brake Master Cylinder Vent?

Methods to repair air leakage from the brake master cylinder vent: 1. Remove the master cylinder and clean it thoroughly, then inspect the air shut-off valve for any cracks. If cracks are found, apply some grease at the cracked area and reassemble it properly; 2. Install air filters on the two branch pipes leading to the master cylinder to solve frequent air leakage issues, and purchase a repair kit for the same model of the master cylinder; 3. If the leather cup of the master cylinder is leaking, it needs to be replaced entirely. When pressing the brake pedal, if you notice the braking feel is significantly softer and the stability of continuous braking decreases, it might indicate poor sealing of the master or slave cylinder pistons, or a crack somewhere in the brake lines causing oil leakage.
