Is a car's water temperature of over 90 degrees normal?

[SanOmar]

A car's water temperature of over 90 degrees is not normal. The reasons for a car's water temperature being too high are as follows: 1. Coolant issues: Coolant leakage or insufficient coolant can cause the engine's water temperature to rise. In this case, the coolant level should be checked. If it is insufficient, first add coolant to the appropriate level, then check after a few days to see if the level has dropped significantly. 2. Radiator fan failure: If the radiator fan fails, when the vehicle is running at high speed, the heat generated cannot be transferred to the coolant in time, affecting heat dissipation and leading to an increase in the coolant's temperature, which can cause boiling and other issues. 3. Water pump failure: Water pump failures can include seized bearings or damaged impellers. Seized bearings are relatively rare, while damaged impellers are more common, such as impeller cracking or the impeller becoming loose from the pump shaft, which slows down the coolant circulation speed and can easily lead to engine overheating issues.
