Is the issue of high car water temperature and coolant leakage serious?

[Erin]

Car water temperature being too high and coolant leakage is a very serious issue, with the following specific reasons: 1. Car coolant leakage: Radiator leakage directly leads to insufficient coolant, causing the engine temperature to rise excessively. This reduces the viscosity of the engine oil, preventing the formation of an oil film between friction surfaces and increasing wear. The pressure inside the engine cylinders becomes too high, impairing operation. Various matching components, especially aluminum ones, may experience thermal deformation. 2. High water temperature: Accelerates engine wear and reduces the lubricating effect of the oil, leading not only to increased fuel consumption but also accelerating the aging and damage of the car engine. Continuously high water temperature without decrease can cause the car radiator to burst due to excessive heat, exacerbating the rise in the car engine block temperature. Prolonged high temperatures can lead to cylinder head deformation. The normalcy of water temperature greatly affects the engine. The optimal water temperature for normal engine operation is around 90 degrees Celsius. Temperatures that are too high or too low can harm the engine.

When I first started driving, the temperature gauge skyrocketed and there was a coolant leak, which was really scary. The problem was definitely serious! Once the engine overheats, it can warp or even be completely ruined. A coolant leak indicates an issue with the cooling system, such as a cracked radiator or a faulty water pump. Without coolant, the engine simply can't cool down. I once experienced this on the highway and had to pull over to let the engine cool—it was even emitting white smoke. The subsequent repairs cost nearly 10,000 RMB. The key is to act immediately: stop the car, turn off the engine, shift to neutral, engage the handbrake, and wait for the temperature to drop slightly before checking for leaks. Regularly inspect the coolant level to prevent minor issues from turning into major headaches. Remember, ignoring it will only double your repair costs. Safety first—don’t push it to drive to the repair shop.

As a seasoned driver with over a decade of experience, overheating and coolant leakage are absolutely not to be taken lightly. This is a serious issue that causes the engine to operate at excessive temperatures, which can easily lead to cylinder explosion or radiator rupture with further coolant loss, directly threatening driving safety. Possible causes include aging water pump seals or radiator damage. Once the coolant is depleted, the engine temperature can skyrocket rapidly. My advice is to pull over immediately when the temperature gauge shows high readings, turn on hazard lights, and never continue driving—otherwise, engine damage repairs can be shockingly expensive. Checking is simple: look for green or red fluid dripping under the car, and don't add water until the leak source is identified. Make it a habit to regularly check coolant levels and use antifreeze to prevent such failures—safety always comes first.

High water temperature and leaking? Stop immediately! It's a serious issue, the engine can easily burn out and leaking accelerates overheating. Park the car, turn off the engine, and let it cool for half an hour—don't open the hood to avoid burns. Then check for leaks, like at hose connections. If there's a leak, quickly find tools for a temporary fix or call a tow truck. Ignoring it can lead to engine failure, expensive repairs, and dangerous driving. Regularly check the coolant level and top it up when low to prevent problems.
