Engine Lights on Cars: A Complete Guide
Introduction
Engine lights are a common sight on cars these days. They can be confusing and frustrating, but they are also very important. An engine light is a warning that there is something wrong with your car, and it needs to be addressed as soon as possible.
There are many different types of engine lights, and each one indicates a different problem. Some of the most common engine lights include:
* **Check Engine Light:** This is the most common engine light, and it can indicate a variety of problems.
* **Service Engine Soon Light:** This light indicates that your car needs to be serviced soon.
* **Low Oil Pressure Light:** This light indicates that your car’s oil pressure is low.
* **High Coolant Temperature Light:** This light indicates that your car’s coolant temperature is too high.
* **Battery Light:** This light indicates that your car’s battery is not charging properly.
What to Do When You See an Engine Light
If you see an engine light on your car, the first thing you should do is pull over and stop the car. If you can, park in a safe place. Once you have stopped the car, turn off the engine and wait a few minutes for it to cool down.
Once the engine has cooled down, you can open the hood and check the fluid levels. Make sure that the oil, coolant, and brake fluid levels are all at the correct levels. If any of the fluid levels are low, add more fluid as needed.
After you have checked the fluid levels, you can start the car again. If the engine light is still on, you should take your car to a mechanic as soon as possible. The mechanic will be able to diagnose the problem and fix it.
