What are the reasons for antifreeze suddenly leaking all over the ground?
2 Answers
The reasons for the decrease in antifreeze include: the auxiliary water tank being overfilled, causing the antifreeze to overflow from the reservoir due to rising water temperature during driving; natural evaporation over time; leakage of antifreeze, which may not be visible to the naked eye but can be detected through pressure testing; and antifreeze seeping into the engine and participating in combustion. The functions of antifreeze: In cold weather, it prevents parts from system failures or cracking due to cooling issues, manages rust prevention, and prevents excessive scale buildup that could clog pipes. It has functions such as anti-corrosion, anti-scaling, anti-boiling, anti-freezing, and anti-rust. Precautions: Try to use the same brand of antifreeze; most antifreeze has a validity period of two years, so ensure the product is within its validity period when adding; avoid mixing with water, as it can produce sediment and severely affect the normal functions of the antifreeze.
The most common reason for antifreeze suddenly leaking all over the ground is aging or ruptured hoses. Having driven for twenty years, I know that radiator hoses can become brittle and crack over time, especially rubber materials that tend to degrade under high temperatures. Other possible causes include cracks or corrosion holes in the radiator itself, a failed water pump seal causing coolant to leak from the drain hole, or loose connections like pipe joints leaking fluid. Once, I encountered this situation when I noticed colored water stains on the ground after parking, and later found out that the radiator had a hole from a collision. If a leak occurs while driving, pull over immediately and turn off the engine to prevent high temperatures from damaging the engine. When inspecting, look for the leak point but avoid touching hot components—it's best to call a professional tow truck for repairs. Regular maintenance, such as replacing antifreeze every two years and checking hose conditions, can prevent such accidents. Never ignore minor issues to avoid major repairs later.
