Because waterless coolant has a longer replacement cycle and better performance. However, its price is much higher than that of ordinary coolant, so car owners need to decide whether to replace it based on their vehicle's needs. Below is some relevant information about coolant: 1. Introduction: Coolant is a type of cooling liquid 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 protecting against scale and corrosion all year round. 2. Chemical Composition: Currently, more than 95% of coolants used domestically and internationally are glycol-based water coolants. Compared to tap water, glycol's most notable feature is its antifreeze capability, whereas water cannot prevent freezing. Additionally, glycol has a high boiling point, low volatility, moderate viscosity that changes little with temperature, and good thermal stability. Therefore, glycol-based coolant is an ideal cooling liquid.

What are the symptoms of a failed turbocharger in large vehicles?

The symptoms of a failed turbocharger in large vehicles are as follows: Engine Power: Black smoke from the exhaust pipe, burning engine oil, and low oil level. If the sealing ring is damaged, exhaust gases can enter the engine lubrication system through the sealing ring, contaminating the oil and rapidly increasing the crankcase pressure. Additionally, during low-speed engine operation, oil may escape through the sealing ring into the exhaust pipe or enter the combustion chamber to burn, leading to excessive oil consumption and the occurrence of "oil burning." Poor Exhaust Heat Dissipation: Prolonged engine operation can result in poor exhaust heat dissipation. When the engine is running, a sharp, screeching noise may occur, preventing sufficient air from entering the combustion chamber, which leads to reduced power and insufficient engine performance.

What are the symptoms of a faulty engine high-voltage line?

Automobile high-voltage line damage symptoms include spark plugs releasing dim yellow and insufficient energy electric sparks, unable to properly ignite the air-fuel mixture, preventing the spark plug electrodes from releasing sparks, leading to unburned mixture and resulting in issues like cylinder misfire. Hazards of engine cylinder misfire: Engine cylinder misfire causes reduced engine power, increased fuel consumption, with very noticeable vibration and noise. Prolonged fuel injection without ignition in engine cylinders can also lead to gasoline flooding the cylinder. Manifestations of ignition coil failure: At idle, the vehicle body shakes noticeably; during driving, when the RPM is below 2500, the body exhibits obvious vibration with weak acceleration; when the RPM exceeds 2500, the shaking sensation disappears. Opening the engine hood and observing the running engine reveals obvious engine vibration.

What causes unstable engine idle speed in the morning?

Reasons for unstable engine idle speed in the morning are as follows: Low car battery voltage: Test the battery voltage with a multimeter. If it's below 10V, replacement is recommended. If around 11V, it can be used temporarily but prepare for replacement. Above 12V is acceptable. Caused by carbon deposits: Check if caused by carbon deposits; if the vehicle has run about 20,000 KM, focus on inspecting and cleaning the throttle body. Spark plug issues: Inspect, test, and replace spark plugs. Fuel supply system: Test and inspect components related to the starting and fuel supply system, such as the starter, fuel pump, and sensors.
