Is It Necessary to Address Minor Coolant Leaks?

Engine gasket coolant leaks must be replaced. If coolant is used for an extended period, it can lead to an increase in freezing point and a decrease in boiling point. Such conditions can affect the normal operation of the engine. Meaning of Coolant: The full name of coolant should be antifreeze coolant, meaning it is a cooling liquid with antifreeze properties. Coolant prevents the cooling liquid from freezing and cracking the radiator or damaging the engine cylinder block or head during cold winter parking. Function of Coolant: Coolant is a type of cooling liquid containing special additives, mainly used in liquid-cooled engine cooling systems. It offers excellent performance in preventing freezing in winter, boiling in summer, and resisting scale and corrosion year-round. Composition of Coolant: The main components of coolant are: fifty percent purified water, forty percent methanol, and ten percent other substances. Types of Coolant: Coolant is generally divided into three types: ethanol-water type, glycerol-water type, and ethylene glycol-water type.

What is the gear speed ratio?

Generally, high-revving engines in French cars follow a shift-up pattern of 20 km/h in 2nd gear, 40 km/h in 3rd gear, 60 km/h in 4th gear, and 80 km/h in 5th gear. For low-revving engines, the pattern is 10 km/h in 1st gear, 30 km/h in 2nd gear, 40 km/h in 3rd gear, 60 km/h in 4th gear, and 80 km/h in 5th gear. Additional information: The principle for deceleration and downshifting is to reduce speed first, then downshift, and skipping gears is allowed. In automatic transmission vehicles, speed and gear should correspond to each other. When the speed matches the gear, the vehicle's performance is at its optimal state, and the thermal efficiency of fuel is the highest. If the speed and gear are mismatched, such as high speed with low gear or low speed with high gear, it will not only increase fuel consumption but also cause damage to the engine and transmission, leading to irreversible harm to the vehicle. Therefore, it is essential to maintain the proper match between gear and speed while driving.

How Long Is It Normal for the Fan to Run After the Car Is Turned Off?

It is normal for the fan to run for one minute after the car is turned off. The reasons why the radiator fan continues to run after the car is turned off are as follows: Protecting the Engine: If the engine coolant temperature at the moment of parking is higher than the acceptable soaking temperature of the engine, the onboard computer will automatically calculate the fan's operating speed and duration, thereby controlling the fan's operation. The higher the engine temperature, the longer the fan will run after parking. When the engine coolant temperature drops below the soaking temperature, the fan turns off. This protects the engine and extends its service life. Preventing Car Spontaneous Combustion: In ordinary cars, the cooling system stops working after the engine is turned off, often causing the engine temperature to rise further after shutdown, leading to damage. Therefore, high-end cars now feature an automatic cooling function. The radiator's power is directly connected to the battery, so even after the engine is turned off, if the temperature remains high, the cooling fan will continue to operate for a period until the temperature cools down, preventing high temperatures from causing the car to spontaneously combust.

How much over the speed limit is driving at 100 in a 70 zone?

Driving at 100 in a 70 zone constitutes speeding between 20% and 50% over the limit. The penalties for speeding and its hazards are introduced as follows: Speeding Penalty Standards: Speeding less than 10% results only in a warning, with no points deducted or fines imposed. Speeding between 10% and 20% incurs a 3-point penalty and a fine. Speeding between 20% and 50% results in a 6-point penalty and corresponding fines. Speeding over 50% leads to a 12-point penalty, corresponding fines, and revocation of the driver's license. Hazards of Speeding: Speeding affects the safety performance of the vehicle. It disrupts the vehicle's operational indices in specific environments, increases the vehicle's workload and stress, and accelerates the wear and tear of components. It is particularly detrimental to the tires, causing not only jump and skid wear but also raising friction temperatures, which can lead to rapid aging and deformation of the tires, increasing the risk of blowouts. Speeding also impairs the driver's ability to operate the vehicle promptly and accurately.

Can 98 and 95 gasoline be mixed?

95 and 98 gasoline cannot be mixed, as mixing them can cause engine knocking. Gasoline is a mixture, and while the chemical compositions of the two are relatively similar with strong anti-knock properties, it is recommended to use them separately to ensure vehicle safety. The difference between 98 and 95 gasoline lies in their octane ratings and quality levels. The specific details are as follows: Different octane ratings: 92 gasoline contains 92% isooctane and 8% n-heptane. 95 gasoline: consists of 95% isooctane and 3% n-heptane. Different gasoline quality levels: The gasoline grade represents the octane rating of the fuel. A higher grade indicates a higher octane rating, which means better anti-knock performance. This results in smoother engine operation, reduced vehicle wear, and better engine protection. It is suggested that using a higher-grade gasoline in a vehicle designed for a lower grade will not cause damage, but the increase in octane rating can alter the fuel's ignition point, leading to delayed combustion in the engine. This reduces the engine's power output and thermal efficiency, resulting in poorer performance. Using lower-grade gasoline in a vehicle designed for a higher grade can cause engine knocking. A significantly lower octane rating reduces the gasoline's ignition point, causing premature ignition during the compression stroke. If combustion occurs before the spark plug fires, resistance will arise during the upward stroke, making the engine run very unstably. Mild knocking may only increase noise without obvious engine damage, but noticeable knocking indicates severe engine conditions. The vibration affects not only driving stability but also causes abnormal wear on pistons and cylinders, and in severe cases, cylinder scoring.
