What is the maximum temperature that a car's water temperature can reach?

[McHolden]

The maximum water temperature of a car can reach 105 degrees Celsius. Below are the specific reasons for high car water temperature: Insufficient coolant: 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, add coolant to the appropriate level. Check again after a few days to see if the level has dropped significantly. If there is a significant drop, the source of the leakage must be identified. Cooling fan malfunction: When the vehicle is running at high speeds, the heat generated cannot be transferred to the coolant in time, affecting heat dissipation. This can lead to an increase in the coolant temperature and may even cause boiling.
