What does Part-Time 4WD mean?

Part-Time 4WD (PartTime4WD) is a four-wheel drive system that allows the driver to choose between two-wheel drive and four-wheel drive. Depending on road conditions, the driver can switch between two-wheel drive and four-wheel drive modes by engaging or disengaging the transfer case. This is a common four-wheel drive configuration used in many "hardcore" off-road vehicles. Although it has the advantages of simple structure and high stability, its drawbacks are also obvious. The driver must stop the vehicle and manually operate the system to switch modes, and the operation steps are relatively complex. In adverse road conditions, it cannot react quickly, often missing the best opportunity to escape. Additionally, due to the lack of a central differential, the four-wheel drive system cannot be used on hard surfaces (paved roads) and cannot make smooth turns on curves. Vehicles equipped with Part-Time 4WD can switch between two-wheel drive, high-speed four-wheel drive, and low-speed four-wheel drive, which are the 2H (high-speed two-wheel drive), 4H (high-speed four-wheel drive), and 4L (low-speed four-wheel drive) gears. Do you understand what Part-Time 4WD is now?

What are the effects of adding a bottle of mineral water when the coolant is insufficient?

Adding a bottle of mineral water when the coolant is insufficient can cause the freezing point of the antifreeze to rise. The mineral water may react chemically with the components in the antifreeze, affecting its functions such as anti-boiling, anti-corrosion, anti-scaling, and lubrication of the cooling system. It is best not to add water to the coolant because the coolant will deplete due to the high temperature of the engine during use. When the coolant level drops below the tank's scale line, it should be replenished promptly. If coolant is not available, distilled water can be added—half water and half coolant is also acceptable. However, once at a repair shop, the water in the tank should be completely drained and replaced with new coolant. Coolant replacement cycle: Coolant is a consumable item in cars. Generally, it needs to be replaced every two years or 40,000 kilometers. However, if you drive frequently, the replacement cycle may need to be shortened. Precautions for replacing coolant: When replacing coolant, it is advisable to choose a high-quality product. Good coolant offers better heat dissipation and rust prevention. It is important to note that when adding coolant, it is best to use the same type. Avoid mixing two different coolants, as this may produce highly corrosive acidic substances that can damage the radiator.

Do You Know the Reasons for Car Idle Vibration?

The vibration of your beloved car during idle may be caused by these reasons. First, engine misfire. Engine misfire means that one or several cylinders of the engine are not working or producing power. In this case, the vehicle exhibits symptoms such as weak acceleration and obvious intermittent airflow from the exhaust pipe. The main reasons for engine misfire are twofold: it could be due to a faulty ignition coil or spark plug, or it might be a problem with the fuel injection system. Second, engine carbon buildup. Since gasoline cannot burn 100% in the engine, carbon deposits will form. Severe carbon buildup in many parts can lead to engine vibration, such as carbon deposits on the valves, spark plugs, piston tops, etc. Third, aging engine mounts. This is also the most common cause of idle vibration in older cars. Engine mounts are the soft connections between the engine and the car body. If they age, they can no longer absorb the engine's vibrations, leading to idle vibration. Do you now understand the reasons for car idle vibration?

How to Remove Windshield Wipers?

First, we need to place a soft cloth or cardboard beneath the wiper to prevent the wiper arm from damaging the windshield. Second, to facilitate wiper replacement, the wiper arm needs to be lifted upright. Note that exposed wipers can be directly lifted, while non-exposed wipers require activating the wiper replacement mode, adjusting the wiper to the highest position before lifting it. Third, remove the old wiper. Wiper connection structures mainly fall into two categories: U-shaped and clip-type. Different vehicle models have different specific structures. Taking the clip-type structure of our car as an example, press the clip to pull out the old wiper. Then reverse the process to install the new wiper. Fourth, return the wiper arm to its original position, remove the protective pad, test the new wiper to confirm everything is correct, and the replacement is complete! Have you learned how to remove windshield wipers?

How to Unclog a Sunroof Drain Tube, Do You Know?

The sunroof drain tube, as the name suggests, is designed to channel water from the sunroof's drainage trough to the underside of the vehicle. Since the sunroof's seal relies on rubber strip compression, it isn't completely airtight. During rainy weather, a small amount of water can seep through the gaps into the sunroof, often carrying impurities like sand and mud. Over time, this can lead to clogging of the drain tube, necessitating its unclogging. The simplest and quickest method is to use a high-pressure air gun, commonly found in repair shops, to blow through the sunroof's drain hole. The high-speed airflow helps remove debris from the tube. Alternatively, you can use a toothpick to unclog the lower outlet, though this method is less effective and slower compared to the high-pressure air gun. Now, do you know how to unclog a sunroof drain tube?

What is the M gear and how to use it, do you know?

The M gear generally refers to the manual mode in a car's automatic transmission. After engaging the M gear, the driver can freely shift up/down using paddle shifters or the gear lever. If you want to experience driving excitement or have more precise control over shifting timing, the manual mode can meet your needs. Some people wonder, in manual mode, will it stall like a manual transmission car? No! If the RPM drops below a certain level, the automatic transmission will downshift automatically. What is the M gear and how to use it, have you learned it now?
