Does Adding Water to Coolant Have Any Impact?
1 Answers
Adding water to the coolant has no impact if the amount of water does not exceed one-quarter of the coolant volume. However, exceeding one-quarter will significantly affect the coolant's performance and may cause the engine to overheat. Additionally, adding water disrupts the proportion of anti-corrosion additives in the coolant, reducing its rust-prevention capability and leading to scale formation. The functions of coolant include: 1. Preventing the coolant from freezing and cracking the radiator or damaging the engine cylinder block during cold weather; 2. Protecting metal parts from corrosion and preventing rubber components from aging; 3. Minimizing scale formation to avoid clogging the circulation pipes and impairing the cooling system's heat dissipation; 4. Preventing the engine from overheating and ensuring it operates within the normal temperature range; 5. Providing lubrication for the water pump, thermostat, and other components.
