The reasons include insufficient coolant; slippage, breakage of the fan drive belt, or incorrect fan blade angle. Here are the solutions for excessively high coolant temperature: 1. Check the coolant level in the radiator. If the coolant is insufficient, replenish it promptly. 2. Inspect the tension of the fan drive belt and the angle of the blades. Rotate the fan blades by hand—if they turn easily, it indicates the fan drive belt is too loose. If the cooling effect improves after adjusting the fan drive belt to the specified tension, then the poor cooling is due to the loose fan drive belt. If the coolant temperature remains high after adjustment, further check for any deformation in the fan blades and whether the blade angle is appropriate, correcting the blade angle if necessary.

What are the reasons for difficult car ignition?

There are several reasons for difficult car ignition: 1. Severe carbon buildup on engine valves. In this case, the throttle body, intake manifold, and carbon deposits on the valves should be cleaned; 2. Weak spark plug energy; 3. Insufficient fuel pressure. Low fuel pressure in the low-pressure fuel circuit can cause the engine to require a second ignition attempt, as the first attempt fails while the low-pressure fuel circuit builds up pressure, allowing the second attempt to succeed; 4. Battery depletion. The solution is to replace the battery or jump-start the car using another vehicle. When encountering abnormal engine ignition, it is essential to promptly inspect and repair the issue to prevent subsequent faults caused by delayed treatment. Moreover, the majority of car starting difficulties stem from the owner's failure to perform regular and quantitative vehicle maintenance, leading to unnecessary losses.

How to Shift into First Gear in a Manual Transmission?

Manual transmission shifting into first gear method: When in neutral, push the gear lever inward with your right hand, then push upward to engage first gear; hold the gear lever and pull it downward to shift into second gear; push the gear lever upward with your hand to engage third gear; lightly cup the gear lever with your palm, spread your fingers to grip it, pull downward into fourth gear while still keeping your palm wrapped around the lever; push the gear lever outward with a backhand motion, then push upward to engage fifth gear. Manual transmission, also known as manual gearbox, is a type of transmission device and the most basic form in automotive transmissions. Its function is to change the gear ratio, also known as the gear ratio, which utilizes the principle of leverage torque by employing larger diameter low-speed gears with longer radii to amplify engine torque, assisting the vehicle in initiating forward movement.

Where is the coolant temperature sensor located on the new Jetta?

The new Jetta 1.4T has two coolant temperature sensors, while the 1.6L model has one G62 sensor located near the water pump on the rear side of the engine. The water level sensor transmits the detected water level signal to the controller. The computer inside the controller compares the actual water level signal with the preset signal to determine any deviation, then issues "open" or "close" commands to the water supply electric valve based on the nature of the deviation, ensuring the container maintains the set water level. The new Jetta is a compact car produced by FAW-Volkswagen, equipped with a 1.4L L4 engine and 5-speed manual transmission, delivering maximum power of 90KW and maximum torque of 132NM.

What Does the Engine Oil Code Mean?

The meaning of the engine oil code is as follows: Taking SAE20W50 as an example, it represents the viscosity of the oil. SAE is the abbreviation for the Society of Automotive Engineers, which currently sets the viscosity grades for engine oils. 20W indicates the oil's low-temperature performance, while 50 represents its high-temperature performance. Introduction to Engine Oil: 1. Low-temperature grades are divided into six levels: 0W, 5W, 10W, 15W, 20W, and 25W. The smaller the number, the better the oil performs in low temperatures. 2. High-temperature grades are divided into five levels: 20, 30, 40, 50, and 60. The larger the number, the higher the oil's viscosity at high temperatures.

What does fuel consumption credit mean?

Fuel consumption credit = (Standard value - Actual value) * Actual production volume. If an enterprise meets the standard, it will generate positive fuel consumption credits; if it fails to meet the standard, it will generate negative fuel consumption credits. Positive fuel consumption credits can be carried forward and transferred among affiliated enterprises. Positive new energy vehicle credits can be freely traded but cannot be carried forward. Negative fuel consumption credits and negative new energy credits must be offset and balanced within the year the report is issued, meaning negative credits generated in the previous year must be offset to zero in the current year. Below is an introduction to the credits: 1. Obtaining fuel consumption credits: Only with an excellent engine + top-tier dual-clutch transmission + widespread mild hybrid system can fuel consumption credits be achieved. 2. Dual credits: A 4% share of new energy vehicles can meet the new energy credit requirement, while an 80% share of mild hybrids is needed to meet the fuel consumption credit requirement.
