What causes the coolant pipe leakage in the 465 engine?

[MacJessica]

There are two possible reasons for coolant pipe leakage: one is a leak in the cooling system causing external coolant leakage, and the other is poor-quality coolant. If methanol-based coolant is used, the methanol and water inside evaporate quickly in summer, leading to excessive consumption and a reduction in coolant levels. Below is relevant information about coolant: 1. Definition: Coolant prevents the freezing of the liquid in the cooling system during cold winter parking, which could otherwise crack the radiator and damage the engine cylinder block. 2. Function: It provides anti-corrosion protection for components of the cooling system, prevents scale buildup to avoid reducing the radiator's cooling efficiency, and ensures the engine operates within the normal temperature range. It must have characteristics such as anti-freeze, anti-boil, anti-corrosion, anti-scale, and no foam, unaffected by seasons or regions.
