What Does the Car Wavy Line Symbol Mean?

It is the coolant temperature warning light. When this light illuminates, it indicates abnormal engine temperature or coolant temperature in the vehicle. Below are the reasons that may cause excessively high engine temperature: 1. Engine overload operation: After aggressive driving, the engine operates under excessive load, causing the temperature to rise too high and triggering the coolant temperature warning light. In this case, you should pull over, turn off the engine, and wait for the temperature to decrease before continuing to drive. Otherwise, it may lead to reduced vehicle power, increased fuel consumption, or even affect the engine's lifespan. 2. Insufficient coolant: When there's a lack of coolant, the engine cannot be effectively cooled, resulting in the illumination of the coolant temperature warning light. Immediate replenishment of coolant is required.
I've been driving for thirty years, and this wavy line symbol is actually called the check engine light. Every time it comes on, my heart skips a beat because there's an 80% chance it's an issue with the engine or emission system, like a faulty sensor, unstable oil pressure, or exhaust problems. Last time this light came on, my car was shaking violently while driving, and later inspection revealed the oxygen sensor was clogged with dust. You really can't take it lightly – when this light appears, you must stop and check, otherwise major engine components could be damaged. I think developing a habit of regular maintenance is particularly important – changing oil and cleaning filters can prevent many such problems.
