Mercedes vehicles typically reach boiling point at 140°C, with the electric fan starting to operate at 120°C. The normal temperature is around 90°C, but fans usually have high and low settings, with the low setting activating at approximately 87°C. Introduction to car coolant temperature: The normal coolant temperature for a car is between 80 and 90 degrees Celsius. Coolant temperature refers to the temperature of the antifreeze. In addition to oil passages, the engine is also equipped with antifreeze passages. Function of antifreeze: The full name of antifreeze is antifreeze coolant. Its primary functions are to cool and lower the engine's temperature, as well as to prevent freezing in winter.

Where is the drainage outlet of the Jetour X90 door?

The drainage outlet of the Jetour X90 door is located on the rubber strip at the bottom of the door. Daily inspection and unclogging of drainage holes: During daily use, you can clean the obvious leaves and debris near the drainage holes inside the car. However, fine silt or debris may be hidden in the hoses or pipes. In addition to visually inspecting the drainage holes, it is also necessary to check the drainage pipes. The drainage holes in the sunroof and engine compartment are the most prone to clogging, so inspections of these two areas will be a priority. The most effective way to check drainage is to pour clean water into the drainage holes and observe the speed and condition of the drainage. Precautions for unclogging drainage: When the vehicle's drainage is not smooth, it is necessary to determine which drainage hole or pipe is causing the problem based on the location of the accumulated water. After identifying the drainage hole, clean the debris near the drainage outlet. When cleaning the sunroof or other hidden hoses inside the car, avoid using hard objects such as iron wires to unclog them, as these hard objects may cause the hoses to break or detach.

Is Manual Transmission Fluid Lifetime-Free?

No, it should generally be replaced every 3 years or 6 years. The primary function of transmission fluid is to maintain the cleanliness of the gear system and to lubricate the transmission components, thereby extending their service life. Below is relevant information about automotive transmissions: 1. Due to different transmission designs, they are categorized into manual transmissions and automatic transmissions (further divided into CVT, AMT, etc.). Each transmission design has distinct technical requirements. Even the same model of transmission configured in different vehicle models will vary in torque, weight, rotational speed, and structure. 2. Therefore, original manufacturers specify their own dedicated transmission fluids. Manual transmission fluid is commonly referred to as gear oil. Based on its quality level, the American Petroleum Institute classifies automotive gear oils into five grades (GL-1 to GL-5). GL-1 to GL-3 have lower performance requirements and are used for lubricating general-load spur and helical gears, as well as gears in transmissions and steering systems. 3. GL-4 is used for lubrication under conditions of high-speed low-torque and low-speed high-torque, such as in automotive hypoid gear drive shafts and manual transmissions. GL-5 offers the highest performance level and is used for lubricating hypoid gear drive shafts and manual transmissions under severe operating conditions with high shock loads.

When making a U-turn at a crosswalk, should the entire car or just the front pass?

When making a U-turn at a crosswalk, the entire car must pass the crosswalk. Below are specific instructions for making a U-turn with a car: 1. Situations where U-turns are not allowed: Motor vehicles are not permitted to make U-turns at locations with no U-turn signs or no left-turn signs and markings, as well as at railway crossings, pedestrian crossings, bridges, sharp curves, steep slopes, tunnels, or other hazardous sections where accidents are likely to occur. 2. Situations where U-turns are allowed: Motor vehicles can make U-turns at locations without no U-turn signs or no left-turn signs and markings, but they must not obstruct the normal passage of other vehicles and pedestrians.

What Causes Gear Shifting Noise?

Here are the specific reasons for gear shifting noise: 1. Damaged transmission housing: Long-term wear and deformation of the transmission housing and bearing seat holes. The noise is loudest when shifting into low gears and decreases progressively when shifting into higher gears, with the direct gear being the quietest. 2. Broken gear teeth: Due to broken teeth on certain gears, impact occurs during meshing. When shifting into that gear, strong impact and vibration occur, causing resonance in the transmission housing. 3. Improper transmission assembly: Incorrect replacement of gears, needle bearings, or bushings in a certain gear, or abnormal assembly clearance, leading to poor gear meshing and noise during transmission in that gear.

What is the mix ratio for M5 mixed mortar?

cement:sand=346kg:1631kg. The following is a related introduction to mixed mortar: 1. Introduction: Mixed mortar refers to a mixture of sand, cement, and lime in a certain proportion, generally used for masonry above ground level. The mixture of sand and cement is called "cement mortar"; the mixture of sand and lime (paste) is called "lime mortar". 2. Advantages: Due to the addition of lime paste, mixed mortar improves the workability of the mortar, making it more convenient to operate and beneficial for increasing the density and efficiency of the masonry. The uses of cement mortar in construction projects include foundation and wall masonry, serving as an adhesive for block masonry materials, such as laying rubble or red bricks with cement mortar.
