What Causes an Increase in Car Antifreeze?
2 Answers
An increase in car antifreeze is often due to engine cylinder head gasket failure, which is a dangerous situation as engine oil enters the cooling system. Antifreeze is a crucial substance in the cooling system, circulating in the radiator and carrying away engine heat through pipes. Besides preventing freezing and cooling, it also has excellent properties such as preventing boiling in summer, rust removal, and corrosion resistance. Situations requiring antifreeze replacement include: 1. The color of the antifreeze in the reservoir has changed, showing a noticeable difference from the original; 2. Sediments or floating impurities are visible in the antifreeze; 3. The antifreeze level exceeds the designated limit; 4. Instruments detect insufficient freezing point of the antifreeze; 5. The engine temperature is too high.
The coolant level in my car suddenly increased? I definitely didn't add any, this can't be right. I regularly check my car's condition myself and know the normal coolant level wouldn't increase without reason - most likely other fluids have mixed in. For example, engine oil might be leaking from the oil pan into the radiator, or the cylinder head gasket could be damaged, allowing coolant to enter the engine compartment. I remember this happened once with my old beater car - during repairs we found internal corrosion had caused fluid displacement. Excess fluid can not only potentially clog pipes but also impair engine cooling, leading to overheating issues. Need to get to a repair shop immediately to identify the leak source and prevent long-term engine damage. I suggest fellow car owners regularly monitor the coolant reservoir level and never delay when noticing abnormalities.
