What faults can be caused by insufficient coolant?

[GraceAnn]

Insufficient coolant can cause the engine water temperature to rise too high, potentially leading to boiling over, which poses significant risks. The reasons for insufficient coolant include: 1. Poorly designed cooling system; 2. Leakage issues; 3. Rapid consumption due to poor circulation; 4. Coolant entering the cylinders; 5. Use of low-quality antifreeze that evaporates quickly. The functions of coolant are: 1. Providing anti-corrosion protection for cooling system components; 2. Preventing scale buildup to avoid reducing the radiator's heat dissipation efficiency; 3. Ensuring the engine operates within normal temperature ranges. Precautions for using coolant include: 1. Avoid mixing different coolants; 2. Steer clear of low-quality coolant products; 3. Do not directly pour undiluted coolant concentrate to prevent deterioration or excessive viscosity at low temperatures.
