What are the reasons for coolant leakage in a car?

[McKarter]

The reasons for coolant leakage in a car are: 1. Radiator damage, poor sealing of the upper and lower water chambers; 2. Loose connections and poor sealing at the overflow tank, water pump joint surface, and cooling system pipelines; 3. Cylinder gasket damage, poor flatness between the cylinder head and cylinder block. The effects of coolant leakage on the engine include: 1. Causing the engine to overheat; 2. Leading to cylinder scuffing, wear, and irreversible damage; 3. Corrosion of components inside the engine compartment. The functions of car coolant are: 1. Providing anti-corrosion protection for cooling system components; 2. Preventing scale formation to avoid reducing the radiator's cooling efficiency; 3. Ensuring the engine operates within the normal temperature range.
