How to Replace Coolant for the New Excelle?

The steps to replace the coolant for the New Excelle are as follows: 1. First, open the engine hood of the vehicle, and you can see the coolant reservoir in the upper right corner. 2. Open the coolant drain plug at the bottom of the radiator to drain the old coolant, then reinsert the plug after the coolant is completely drained. 3. Then, add the new coolant of the same type, and make sure to tighten the coolant cap after filling. Below is a brief introduction to coolant: (1) The full name of coolant should be antifreeze coolant, meaning it has antifreeze properties. (2) Coolant prevents the cooling liquid from freezing and cracking the radiator or damaging the engine block or cylinder head during cold winter parking. Many people think coolant is only used in winter, but in fact, it should be used all year round. (3) Coolant is a special additive-containing liquid primarily used in liquid-cooled engine cooling systems. It offers excellent performance in preventing freezing in winter, boiling in summer, and resisting scale and corrosion throughout the year.

What Causes Excessive Water from a Car's Exhaust Pipe?

Water dripping from the exhaust pipe indicates that your fuel supply system is in excellent condition. Here are the three necessary conditions for water dripping from the exhaust pipe: 1. The air-fuel mixture ratio is correct. 2. The engine compression pressure is high. 3. The exhaust temperature is low. Below is detailed information about water dripping from the exhaust pipe: 1. Whether it's fuel injection or carburetor supply, the mixed air-fuel ratio is just right (indicating fuel efficiency). High engine compression pressure signifies good engine condition, with no signs of cylinder wear. 2. If the engine shows slight signs of burning oil, the cylinder pressure will decrease, leading to incomplete combustion. Incomplete combustion prevents water dripping, as the exhaust temperature won't be low. 3. A low exhaust temperature indicates correct ignition timing. The combustion gases are concentrated within the cylinder, with little or none escaping into the exhaust pipe (indicating strong engine horsepower output). For water to drip from the exhaust pipe, the engine itself must meet these conditions.

What Causes Volkswagen Window Failure to Roll Up/Down?

The reasons for window glass failing to roll up or down include deformation or damage to the window channel, loosening of the regulator mounting screws, or damage to the window regulator. Below are solutions for window glass failure to roll up/down and classifications of automotive glass: Solutions for Window Glass Failure to Roll Up/Down: Turn on the ignition switch, pull and hold the switch in the upward position. After the glass reaches the top, continue holding for more than 3 seconds. Release the switch and immediately press and hold it down to lower the glass completely, waiting for more than 3 seconds. Repeat the upward movement once more to complete the initialization procedure, restoring the window roll-up/down function. This method is effective for most vehicle models. If restoration is unsuccessful, it is necessary to visit a professional repair shop for inspection. Classifications of Automotive Glass: Mainly divided into laminated glass, tempered glass, and regional tempered glass, which can withstand strong impacts. Automotive glass is categorized by location into four types: front windshield, side window glass, rear windshield, and sunroof glass.

What is the reason for the Sundiro Honda Century Dream only reaching 40 km/h at full throttle?

Sundiro Honda Century Dream only reaching 40 km/h at full throttle may be due to reasons such as not being in gear or the motorcycle speed limiter. The specific reasons are as follows: Not being in gear: The speed ranges for motorcycle gears 1 to 5 are: 1st gear (climbing speed) between 10 to 20 km/h, 2nd gear between 20 to 30 km/h, 3rd gear between 30 to 50 km/h, 4th gear between 50 to 60 km/h, and 5th gear above 60 to 100 km/h. You can try shifting gears again. Motorcycle speed limiter: It is generally installed on the carburetor assembly. Its most basic principle is to limit the throttle opening, thereby restricting the maximum speed. You can visit a professional shop to remove the speed limiter.

Why Isn't New Car Engine Oil Life at 100%?

Due to the fact that new cars cannot be transported entirely by flatbed trucks during transit, they accumulate mileage, which is why the engine oil life of a new car is not at 100%. Engine Oil Life: Engine oil life refers to the usable duration of the oil. When the oil exceeds the specified time or mileage, it must be replaced. Engine oil also has a shelf life. If it exceeds this period, the lubricity and adhesion of the oil will degrade, leading to unnecessary wear on the engine. Calculating Engine Oil Life: The lifespan of engine oil is not calculated based on mileage but rather on engine operating hours. Conventional oil typically lasts between 100 to 150 hours, while synthetic oil can last 200 to 300 hours. When manufacturers recommend oil change intervals, they use the following calculation method: assuming an average speed of 80 km/h, 100 hours of operation would equate to 8,000 to 12,000 km. For conventional oil, it's advisable for owners to change the oil approximately every 5,000 km.

What grade of gasoline does the Volkswagen T-Roc use?

The Volkswagen T-Roc uses 95-octane gasoline. The vehicle's manual specifies the recommended fuel grade for the engine, and there is also a fuel grade label on the inside of the fuel tank cap. The gasoline octane rating refers to the octane number, which indicates its anti-knock properties. The higher the octane number, the better the anti-knock performance of the gasoline. The required gasoline grade for a car is determined by the engine's compression ratio. A higher compression ratio requires gasoline with better anti-knock properties. In terms of dimensions, the Volkswagen T-Roc measures 4318mm in length, 1819mm in width, and 1582mm in height, with a wheelbase of 2680mm. The overseas version of the Volkswagen T-Roc is positioned as a compact SUV, but after being introduced to the domestic market, the FAW-Volkswagen T-Roc underwent a wheelbase extension, elevating it to the entry-level compact SUV segment.
