What are the effects of car coolant leakage on the engine?

[DavidFitz]

When the coolant is completely leaked, the cooling system cannot function properly, and the heat generated by the engine cannot be exchanged, causing the engine temperature to rise continuously. This can lead to engine damage due to overheating. More extended information is as follows: 1. Reasons for coolant leakage: The seal at the connection between the coolant reservoir and the radiator may not be tight enough, or the rubber hose may have aged and cracked. Additionally, if the radiator frequently requires water refills in an older car, it might be due to rust perforation in the radiator. 2. Functions of coolant: Primarily, it dissipates heat to prevent engine damage from excessive temperatures in summer. It also prevents the cooling system from freezing and cracking during prolonged parking in extremely cold winters. Therefore, coolant leakage should be repaired immediately.
