What are the causes of the high temperature issues in the Besturn B50?
1 Answers
The following are the reasons for the high temperature in the Besturn B50: 1. Electrical circuit failure: The electronic cooling fan does not rotate, reducing the radiator's heat dissipation capacity. At this time, check the operation of the electronic fan. Unplug the electronic fan's wire connector and directly power it with a power line. If the electronic fan rotates, it indicates that it is working properly; if it does not rotate, it indicates damage. 2. Mechanical failure: The fan coupling lacks oil, is damaged, or stuck, causing the cooling fan not to rotate. When the engine runs for a long time, the water temperature is high or even boils. This is generally caused by the thermostat failing, resulting in poor water circulation. After the water temperature rises, the thermostat valve does not open, and the cooling water does not circulate in a large loop, thus failing to dissipate heat and regulate the water temperature. In tropical regions of southern China or in emergencies, the thermostat valve can be removed. 3. Improper assembly: For engines that have undergone major repairs or are newly assembled, during the installation process, high water temperature often occurs due to mismatched dimensions or fitting clearances. For a newly overhauled and assembled engine, running at medium speed for about half an hour may result in high water temperature. This is generally due to the gap between the piston or piston ring and the cylinder being too small. Prolonged operation can also cause issues such as stuck rings, broken rings, and cylinder scoring.
