What is the indicator for insufficient car antifreeze?
1 Answers
The indicator for insufficient car antifreeze is a small sailboat-like symbol displayed on the dashboard. When the engine coolant is low, this sailboat-like symbol will appear on the car's dashboard. This means you need to add coolant (antifreeze) to the engine, which can be poured directly in. The method for replacing car coolant is as follows: 1. Loosen the screw at the bottom drain port of the radiator, being careful to loosen it rather than remove it entirely to prevent it from being too tight after the engine heats up; open the pressure seal cap of the main radiator. 2. Warm up the engine until the water temperature is normal, approximately 5-10 minutes, by which time the thermostat should be in or transitioning to the open state, and the engine's water circulation begins; loosen the radiator drain screw to start draining the antifreeze, observing the flow rate, and once it decreases, turn off the engine. 3. After completely draining the antifreeze, tighten the drain screw and refill the main radiator with new antifreeze until the liquid level is visible at the fill port. 4. Replace and tighten the pressure seal cap, remove the overflow tank and pour out the old antifreeze, then add new antifreeze up to the upper fill line; warm up the engine to purge air, then wait for it to cool, observe the liquid level in the overflow tank, and top up the antifreeze to the upper fill line.
