Overfilling engine oil can cause oil splashing, which may lead to oil burning in the combustion chamber and carbon deposits. Additionally, if the engine oil is not changed for a long time, it can become watery and lose its sealing function. Here is some information about engine oil: 1. Different viscosity grades of lubricating oil should be selected based on environmental temperature and vehicle condition. Multi-grade oil is recommended for year-round use. 2. For drivers in southern regions, choosing a lower low-temperature viscosity can improve startup performance and allow the oil to reach the optimal operating temperature and viscosity faster. 3. For drivers in northern regions, the low-temperature viscosity should be selected based on the local winter minimum temperature, ensuring the oil has an appropriate pour point parameter.

How Many Kilometers Should You Replace the Belt?

A car typically has two belts: the timing belt and the accessory belt. The replacement interval for the timing belt is almost the same for all vehicles, generally around three years or 60,000 kilometers. When replacing the belt, the tensioner pulley and idler pulley should also be replaced simultaneously, as their lifespan is similar to that of the belt. Even if the tensioner pulley still functions at the moment, its remaining lifespan is uncertain. Here’s additional information: The replacement interval for the accessory belt varies significantly among different vehicle brands, ranging from 3-6 years or 60,000-100,000 kilometers. The exact replacement time should be checked in your vehicle’s maintenance manual. During replacement, the tensioner pulley and idler pulley should also be replaced, as their lifespan is comparable to the belt. If the tensioner or idler pulley fails, it may lead to belt damage or even breakage.

Where is the position light switch located?

Generally on the left side, where the headlight switch is adjusted. Turning to the first light position activates the position lights. There are two lights each at the front and rear of the vehicle. The dashboard displays two opposing small bulb-like indicators lighting up. Position lights are the outermost lights at the front and rear of the vehicle. Large trucks also have position lights on the roof and sides. Literally, 'position light' implies a warning function. Here are additional details: Position lights are installed along the edges of the vehicle's roof, indicating both height and width. Safety regulations mandate installation for vehicles exceeding 3 meters in height. Position lights must be white at the front and red at the rear. Vehicles wider than 2.10m must be equipped with them, while those between 1.80-2.10m may have them optionally. Chassis with cabs may optionally install rear position lights.
