What to Do When the Engine Water Temperature Is Too High?

[SanFrank]

Solutions for excessively high engine water temperature are as follows: 1. Sudden water temperature rise. First, check if the radiator is overheating. If the radiator temperature is too high, it indicates a blown cylinder head gasket. At this time, pay attention to whether the mating surface between the engine block and the cylinder head is severely warped or deformed. If deformation is found, repair it promptly. If the radiator temperature is not high, it indicates poor coolant circulation. Check whether the fan belt is broken or severely slipping. 2. Non-sudden water temperature rise. For a temperature rise that does not occur suddenly, increase the engine speed and observe whether water is overflowing from the filler opening, while noting whether it is a large or small amount of overflow. If there is a large amount of overflow and the radiator temperature is uneven, it indicates that some cooling pipes are blocked, especially during severe winter conditions. When there is a small amount of overflow from the filler opening and the engine temperature is low at the front and high at the back, it indicates that the water distribution pipe is damaged or blocked and should be replaced promptly.
