It’s important to remember that a car stalling and the check engine light coming on can be a sign of a serious problem. By following these safety tips, you can help to protect yourself and others while you’re waiting for help to arrive.
Check the Engine
Once you’re in a safe location, you can begin to check the engine for any obvious problems. Here are some things to look for⁚
– Check the oil level. A low oil level can cause your engine to stall. Check the oil dipstick to see if the oil level is low. If it is, add oil until it reaches the full mark.
– Check the coolant level. A low coolant level can also cause your engine to stall. Check the coolant reservoir to see if the coolant level is low. If it is, add coolant until it reaches the full mark.
– Check the air filter. A dirty air filter can restrict airflow to the engine, which can cause it to stall. Remove the air filter and check it for dirt and debris. If it’s dirty, replace it with a new one.
– Check the spark plugs. Worn spark plugs can cause your engine to stall. Remove the spark plugs and check them for wear. If they’re worn, replace them with new ones.
– Check the battery. A weak battery can cause your engine to stall. Check the battery terminals to see if they’re clean and tight. If they’re not, clean them and tighten them.
If you don’t see any obvious problems with the engine, you can try restarting your car. If it starts and runs нормально, then you may have been able to fix the problem yourself. However, if your car continues to stall or the check engine light remains on, you should take it to a mechanic for further diagnosis.
