How to Replace the Antifreeze in a Bora?

The tutorial for replacing the antifreeze in a Bora is as follows: 1. Drain the coolant: First, open the reservoir cap (ensure the radiator cap is tightly sealed), then unscrew the drain switches on the cylinder block and radiator. This should be done while the engine is running at low speed and is warm. 2. Add new coolant. Precautions for replacing the antifreeze are as follows: 1. After the coolant is completely drained, tighten the drain switches on the cylinder block and radiator. 2. Close the radiator cap, let the engine run until it reaches normal operating temperature, then turn it off and wait until it cools to room temperature. 3. Observe the liquid level in the reservoir and add coolant as needed until no air bubbles appear in the reservoir when the engine is idling. 4. Fill the radiator with the specified coolant through the filler port until the liquid level in the reservoir reaches the designated "MAX" mark.

How to Remove the Glove Box in a Magotan?

Removing the glove box in a Magotan is quite simple. There are three screws at the bottom of the glove box. After unscrewing these three screws, open the glove box to find five more screws inside. Remove them one by one to take out the glove box. Here are more details about the glove box: 1. Generally, the glove box is removed to replace the cabin air filter. The cover of the air filter box is secured with a clip. Gently push the clip aside to remove the cover and access the filter. The filter has a pull tab; a gentle tug will bring it out. Install the new cabin air filter in the same orientation as the old one, paying attention to the installation direction. 2. There are two types of glove box designs: fixed and flip-down. The fixed type features an inner compartment as part of the glove box, with the storage space located within the dashboard structure. The flip-down type, on the other hand, integrates the inner compartment with the door panel, placing the storage space on the door itself. When the door is opened, the inner compartment flips out along with it. 3. The flip-down design generally makes it easier for users to access items inside. However, because additional structures are required on the door panel, it reduces the available internal space of the glove box, which is less ideal for storing items or installing internal components like glove box lights. Conversely, the fixed type offers more space but is less convenient for front-seat occupants to access items.

Who Invented the Rotary Engine?

The German engineer Felix Wankel produced the world's first rotary engine in 1957 and obtained the patent. However, currently only the Japanese automaker Mazda is conducting research on it. Below are specific details about the rotary engine: 1. The rotor of a rotary engine performs work once per rotation. Compared to a conventional four-stroke engine, which performs work once every two rotations, it has the advantage of a high power-to-displacement ratio (the engine can output more power with a smaller displacement). 2. Due to the axial operation characteristics of the rotary engine, it can achieve higher operating speeds without requiring a precisely balanced crankshaft. The entire engine has only two rotating components, which greatly simplifies the structure compared to a conventional four-stroke engine with over twenty moving parts, such as intake and exhaust valves, significantly reducing the likelihood of failure. In addition to the above advantages, the rotary engine also features a smaller size, lighter weight, and a lower center of gravity.

Is There Water in the Exhaust Pipe in Winter?

In winter, there is water in the exhaust pipe because gasoline produces water and carbon dioxide after complete combustion. Here are the reasons why water dripping from a car's exhaust pipe is normal: 1. Correct air-fuel mixture ratio: When the vehicle's air-fuel mixture ratio is correct, water dripping from the exhaust pipe is normal. Whether it's an electronic fuel injection or carburetor engine, a correct air-fuel mixture ratio indicates that the vehicle's compression ratio is normal, and fuel consumption is within the normal range. 2. Normal engine cylinder pressure: When water drips normally from the vehicle's exhaust pipe, it indicates normal engine cylinder pressure, showing that there is no wear in the engine cylinder block and that all parts inside the engine are working properly. This method can be used to determine whether the fuel is burning normally. 3. Normal exhaust temperature: Normal water drainage from the vehicle's exhaust pipe also indicates that the exhaust temperature is normal, meaning the engine's power output is stable.

What Are Some Clever Methods for Repairing Small Dents on Car Doors?

Here are specific methods for repairing small dents on car doors: 1. Manual Repair: Prepare construction tools, including various lever tools, professional lighting, repair hammers, and specialized leveling pens. For car dent repair, tools are not the most important; what matters most is the technician's skill, attention to detail, and patience. 2. Car Dent Repair Construction: Use the visual effect of light refraction to determine the position and extent of the dent. Apply the principle of leverage to massage the internal 'skin' of the car body, gradually releasing the tension at the dented area. This maximizes the 'entropy' value on the surface of the door dent, restoring it to its original shape, achieving fast, accurate, and complete repair of the car body dent. 3. Light-Facing Repair: Check the repair effect by facing the light or sunlight. If no flaws are visible, the repair is considered successful.

What Causes Unstable Car Idling?

There are several reasons that can cause unstable car idling, including severe engine carbon buildup, excessive carbon deposits in the throttle body and intake manifold, faulty fuel pressure regulator, clogged fuel injectors, blocked fuel filter, spark plug carbon buildup, incorrect spark plug gap, and excessive resistance in high-voltage wires. Below is a detailed explanation: When there is excessive carbon buildup inside the engine, the gasoline sprayed by the cold-start injector is largely absorbed by the carbon deposits, resulting in an overly lean air-fuel mixture during cold starts and making it difficult to start the engine. In this situation, the engine will only start easily once the carbon deposits have absorbed enough gasoline to become saturated. After starting, the gasoline adsorbed on the carbon deposits is then drawn into the combustion chamber by the engine's vacuum suction, causing the air-fuel mixture to become overly rich. This alternation between lean and rich combustible mixtures leads to unstable idling after a cold start.
