What Causes Engine Coolant Leakage?
2 Answers
Reasons for engine coolant leakage: 1. Possible loose sealing at the connection between the coolant reservoir and the radiator. 2. Aging and cracking of rubber hoses. 3. If the car is old and the radiator is frequently filled with water, it may be due to rust perforation in the radiator. Introduction to coolant: 1. The full name of coolant should be antifreeze coolant, meaning it has antifreeze properties. 2. Coolant is a type of cooling liquid with special additives, mainly used in liquid-cooled engine cooling systems. It offers excellent performance in preventing freezing in winter, boiling in summer, and protecting against scale and corrosion all year round.
Engine coolant leakage is something I have plenty of hands-on experience to share. The most common issue is aging hoses—those rubber tubes become stiff and brittle over time, especially in winter when temperature fluctuations are significant. A slight contraction can cause cracks or loose connections, leading to coolant seepage. The radiator is another major culprit. If you frequently drive on gravel roads, the radiator may develop cracks from impacts or rust-induced leaks. The water pump's sealing ring is prone to wear, and over time, coolant can escape through the gaps. The thermostat's pipe connections may also loosen. Ignoring these minor issues can result in gradually decreasing coolant levels, causing the engine temperature to skyrocket—leading to reduced power at best or engine damage at worst. So, if you notice any damp spots, immediately pull over to a safe spot to check the fluid level and head to a repair shop without delay. Regular maintenance checks on hoses and the radiator can save you a lot of trouble.
