What are the reasons for the old Mazda 6 not making any sound or responding when starting?

Is it normal for the temperature gauge to show 5 bars?

It is not normal; 2 to 4 bars are considered normal. If the car's water temperature is too high, it can lead to poor engine cooling and excessive temperature. The expansion of components will reduce the clearance between parts, and the viscosity of the engine oil will decrease at high temperatures, accelerating wear on various components. If not addressed immediately, the engine may suffer severe damage due to overheating. Additional information: 1. Car temperature gauge: The car temperature gauge is marked with the letters "C" and "H" or uses white and red zones to indicate temperature. "C" stands for "cool," while "H" stands for "hot." The water temperature refers to the coolant temperature, and after the engine warms up, a normal reading is usually between 70-90°C. 2. How the temperature gauge works: The sensor of the temperature gauge is a thermistor-type sensor, fixed with threads to the engine's cooling water passage. The thermistor determines the current flowing through the coil of the temperature gauge, which drives the needle to move accordingly.

Is it possible not to be photographed when crossing a single yellow line?

"There is a possibility that crossing a single yellow line may not be photographed. Single yellow lines are divided into solid and dashed lines. Below are different scenarios regarding whether crossing a single yellow line will be photographed and related information about crossing yellow lines: Different scenarios regarding whether crossing a single yellow line will be photographed: Solid lines will definitely be photographed: If it is a solid line, whether single or double, crossing it constitutes a traffic violation. If you cross a single yellow line or make a U-turn near a camera, you will definitely be photographed. Dashed lines: If it is a dashed line, often set on narrower roads to distinguish lanes for different directions of travel, you can borrow the lane to overtake or make a U-turn under safe conditions. Related information about crossing yellow lines: Crossing yellow lines is a violation of traffic rules. Yellow lines are divided into single and double yellow lines, and neither type allows vehicles to cross or straddle the line. If violated and recorded by traffic police or cameras, traffic penalties will be imposed, usually involving a fine and a deduction of 3 points. When encountering a dashed yellow line during driving, you may cross the line or make a U-turn without affecting vehicles in the opposite lane."

Why Are Second-hand Alto Cars So Expensive?

The high value retention rate of the Alto is attributed to factors such as brand reputation, quality reliability, and market circulation volume. In the microcar segment, the Alto has undergone 100 years of development, making it the world's tenth-largest automaker by 2008. Its models are renowned for being economical, fuel-efficient, reliable, and durable. In the small-displacement vehicle category, the Alto is widely recognized as the 'King of Compact Cars' due to its extensive R&D and manufacturing expertise. Additional details about the Suzuki Alto are as follows: 1. Value Retention Rate: Over the past five years in the used car market, the Suzuki Alto's average value retention rates were 68.64%, 60.54%, 54.80%, 48.70%, and 44.73%, respectively. According to statistics from the China Automobile Dealers Association, the average first-year value retention rate for domestic used cars is 70%, and the third-year average is 60%. The Alto's third-year rate is slightly below the average, classifying it as a moderately value-retaining model. 2. Engine: The Alto is equipped with the Suzuki K10B all-aluminum engine, praised in the industry for its high power and low fuel consumption. Significant improvements have been made in its exterior, interior, engine, and configurations, making it at least five years ahead of its peers. With its robust body and affordable price, the Alto has achieved a sales milestone of 500,000 units in China, a trend that continued even after the launch of the new Alto. Given its reputation as the 'King of Microcars,' the phenomenon of high prices for older models in the used car market is hardly surprising.

How to Break in a Manual-Automatic Transmission Car?

Here are the methods for breaking in a manual-automatic transmission car: 1. Warm up the car before starting: After the car has been parked overnight, the engine oil flows back into the oil pan. After starting the car, it takes some time for the oil to fully lubricate all components of the engine from the oil pan. If you drive immediately after starting, the internal components of the engine may not be fully lubricated, leading to abnormal wear. Simply warm up the car before driving, and wait until the idle speed stabilizes before moving off. 2. Speed control during the break-in period: The speed during the break-in period should be increased gradually. For the first 500 kilometers, try to maintain a speed of 60-70 km/h, with the engine speed not exceeding 2,200 rpm. From 500 to 1,000 kilometers, the speed can be increased to 90-100 km/h, with the engine speed generally kept below 2,500 rpm. After 1,000 kilometers, the speed can be increased to below 120 km/h, with the engine speed not exceeding 3,000 rpm. 3. Gear control: During the break-in period, it is important to control the gear shifts properly in a manual-automatic transmission. Avoid suddenly shifting into P or R gear while driving, as this can cause severe impact on the transmission and may even damage it. When shifting into reverse, ensure the car is completely stopped before doing so. Additionally, practice using the manual mode in areas with good road conditions. 4. Avoid coasting in N gear: Do not coast in N gear while driving. When in N gear, the transmission's power pump stops working, leading to abnormal wear due to lack of coolant and lubrication, which shortens the transmission's lifespan and increases fuel consumption. 5. Avoid emergency braking: Try to avoid emergency braking during the break-in period. Emergency braking can cause impact on the car's braking system. Since the car's components are not fully broken in during this period, frequent emergency braking is detrimental to the break-in process and can also damage the car's chassis. 6. Generally, do not change the engine oil prematurely: The oil used during the break-in period is usually a specialized lubricant with low viscosity, excellent heat dissipation, cleaning, and antioxidant properties. Some oils even contain grinding agents that aid in the break-in process. Changing the oil too early can hinder the break-in process.

What Are the Reasons Why the Radiator Temperature Cannot Rise?

Car coolant temperature cannot rise may be due to insufficient coolant in the car, or a malfunctioning cooling fan, or it could be caused by a faulty circulation water pump. Solutions for the coolant temperature not rising: It is necessary to check the coolant level and also to inspect for any oil leaks. If there are no oil leaks, simply adding coolant will suffice. The role of the cooling fan is to transfer the heat generated by the car to the coolant. If the cooling fan malfunctions, it can lead to a failure in the cooling system, and in severe cases, it may even cause the engine to overheat. If this situation occurs while driving, it is important to stop and inspect the vehicle promptly. Additionally, attention should be paid to whether the water pump is malfunctioning, as this can disrupt the engine's water circulation, directly causing the water cooling system to fail, which in turn leads to abnormal water temperature. Generally, water pump abnormalities are caused by seized bearings or damaged shutters, and these issues require immediate repair to avoid affecting the engine's normal operation. It is important to note that under no circumstances should tap water be used as a substitute for antifreeze, nor should different types of antifreeze be mixed, as this could lead to dilution or sedimentation of the antifreeze, ultimately causing it to lose its effectiveness. Any malfunctions should be inspected and repaired promptly, as vehicle safety is not something to be taken lightly. Hazards of the coolant temperature not rising: The temperature of the mixture (or air) entering the cylinder is too low, resulting in poor quality combustible mixture, making ignition difficult or combustion slow, leading to decreased engine power and increased fuel consumption; water vapor in the combustion products is prone to condense into water and combine with acidic gases to form acids, exacerbating corrosion on the engine body and parts; unvaporized fuel can wash away and dilute the oil film on the surfaces of parts (cylinder walls, pistons, piston rings, etc.), accelerating wear on these components.
