How to Determine Insufficient Coolant?

Determining insufficient coolant can be done through the following steps: 1. Press the one-touch start button to initiate the vehicle, and the system will perform a self-check. 2. Check the vehicle dashboard. There will be fluid level indicators; abnormal levels will be flagged, allowing you to assess the coolant level. 3. Locate and pull the engine hood release handle from the driver's seat inside the vehicle. 4. Find the latch under the hood, open it, and secure the hood in place. 5. Inspect the coolant reservoir, which is marked with maximum and minimum level indicators. Coolant, fully known as antifreeze coolant, is a fluid with antifreeze properties designed to prevent the coolant from freezing in cold weather, which could otherwise cause the radiator to burst or damage the engine cylinder block.

The most obvious way is to check the water temperature gauge on the dashboard. If you notice the needle steadily climbing into the red zone while driving, be cautious. After parking, don't rush to turn off the engine; wait a few minutes, then open the hood and locate the transparent plastic reservoir (the overflow tank). Check if the liquid level is below the minimum mark. If there's no mark, the coolant should at least cover the pipe at the bottom of the reservoir. Check again once the engine has cooled down, as the liquid level rises when the engine is hot. If you're unsure, keep a bottle of distilled water on hand for a temporary top-up, but make sure to visit a repair shop later to test the concentration.

Last time I went on a long trip, I suffered a loss by not paying attention to the coolant, and the engine almost got ruined. Now I have to squat in front of the car every now and then, checking the fluid level in the auxiliary reservoir. It's especially prone to running low in winter because the aging seals in old cars can cause leaks. There's also a clumsy method: opening the radiator cap before a cold start to see if the fluid level is full enough, but you have to wait until the car cools down completely, or the high-temperature steam can scald your skin. If you find the fluid level is low, never mix in antifreeze of a different color randomly, as it can clog the pipes.

For beginners, remember these three steps: First, check the coolant reservoir level before cold starting the engine. Second, test the heater to see if it gets hot enough (insufficient cooling will result in weak warm air). Third, listen for how frequently the electric cooling fan operates. During regular maintenance, have them check the antifreeze's freezing point – if it's too low, it will affect circulation efficiency. If the engine overheating warning light comes on, don't push it, or you'll face cylinder scoring and a major repair costing thousands.

Don't panic if you notice abnormal water temperature. Pull over to a safe spot and let the car rest. Open the hood and touch the hoses—if they're too hot to handle, it indicates a real cooling system issue. Older car owners should watch for coolant leaks (sweet-smelling puddles under the car). Also check if the radiator fins are clogged; clean them after highway drives during seasons with heavy willow catkins. Poor AC performance may also signal cooling system problems, as their circulation systems are interconnected.

Car modification enthusiasts all understand the importance of cooling system maintenance. I check the overflow tank every 500 kilometers, using a chopstick to measure if the level markings are unclear. Those with modified powertrains need even more frequent checks, as turbochargers' high temperatures consume coolant rapidly. Keeping a bottle of OEM coolant in the trunk is safest - distilled water works for emergency long-distance use but lowers the boiling point. Coolant should be replaced annually at minimum, otherwise radiator corrosion becomes a costly consequence.
