Here are the solutions for the crankshaft oil seal leakage in Wuling Hongguang: 1. The runout between the oil seal hole and the crankshaft should not exceed 0.15 (i.e., the coaxiality between the oil seal hole and the crankshaft). 2. Purchase high-quality oil seals (PTFE oil seals with good sealing, high-temperature resistance, and high linear speed tolerance). 3. When installing the oil seal (note that the rear oil seal installation usually requires a fixture), it is best to use a fixture; otherwise, the oil seal may be damaged and cause oil leakage. 4. Replace the engine in time. If the engine has been used for a long time, the rear oil seal naturally ages, and cracks may form at the lip, leading to oil leakage.

How to Make an Extra Car Key?

How to Check the Car Water Temperature Gauge?

The method to check the car water temperature gauge is: 1. The temperature scale ranges from C to H, where C represents 60 degrees. When the needle points to C, it means the water temperature has reached 60 degrees; 2. The red H zone indicates 110 degrees. If the needle enters the red zone, it means the water temperature is too high. The normal operating temperature for the water temperature gauge is between 70 to 90 degrees. Its function is to indicate the temperature of the coolant in the radiator while the engine is running, as the engine requires a certain operating temperature to function properly. The reasons for an excessively high water temperature gauge reading include: 1. Insufficient coolant due to low fluid levels or leaks; 2. Abnormal cooling caused by a malfunctioning radiator fan; 3. Poor heat dissipation due to a faulty circulation water pump; 4. Engine issues or cooling system malfunctions.
