What happens if you don't use antifreeze?

Answer 1

If you don't use antifreeze in your vehicle's cooling system, the coolant can freeze in cold temperatures, leading to potential engine damage due to ice expansion. In warmer conditions, the absence of antifreeze can cause the engine to overheat, as antifreeze helps regulate temperature and prevents boiling. Additionally, antifreeze contains corrosion inhibitors that protect the metal components of the cooling system; without it, rust and corrosion can develop, leading to costly repairs. Overall, neglecting antifreeze can significantly harm your vehicle's performance and longevity.
