What are the effects of running out of coolant?
3 Answers
The effects of running out of coolant are: 1. It can cause the engine to overheat, and in severe cases, lead to engine damage; 2. It may result in the engine or radiator freezing, causing engine failure. The functions of automotive coolant are: 1. To provide anti-corrosion protection for the engine's cooling system; 2. To prevent the engine water from boiling when the temperature reaches 100 degrees Celsius; 3. To prevent the formation of scale, which could reduce the radiator's cooling efficiency; 4. To ensure the engine operates properly under low-temperature conditions. The method for replacing coolant is: 1. Open the vehicle's engine hood, and locate the coolant reservoir in the upper right corner; 2. Open the coolant drain plug under the radiator to drain the old coolant; 3. Add new coolant, tighten the cap, and the coolant replacement is complete.
Last time the antifreeze leaked out and I didn't notice. After driving a few hundred kilometers, the engine started humming, and the temperature gauge went all the way to red. When I stopped to check, I found the cylinder head was deformed, and the repair cost me thousands. Antifreeze doesn't just prevent freezing in winter; it also lubricates the water pump and reduces corrosion. Without it, the system is prone to rust and leaks. If neglected for a long time, the engine's lifespan can be halved. When driving, always take a glance at the coolant level in the radiator. If it's too low, top it up immediately with the same type of antifreeze—don't mix brands. Regularly replacing it can save you a lot of money in the long run.
Insufficient antifreeze can easily cause engine overheating. During high-speed driving, the temperature may rise sharply, potentially burning out cylinders or gaskets. In winter, lower temperatures can freeze and crack the radiator pipes, leading to major disasters. When I was young, I saw cars stranded on the road simply because they didn't check the antifreeze level in time. Too low a level can also affect the heater, leaving passengers cold due to inadequate heating. Safety comes first—make it a habit to check the coolant every month. If the color turns cloudy or shows sediment, it indicates a problem. Before replacing, drain the old fluid to avoid residue damage.
