Every motorist has experienced car problems. Some of these problems require professional diagnosis and repair, which can be time consuming and expensive. There are many engine problems that you can diagnose yourself without taking your car to a mechanic. This article focuses on the most common problems you can solve yourself.
engine does not start
This is perhaps the most stressful car engine problem. When you run into problems, you may wonder if the problem is just a problem or if you need professional help. The most common cause of this problem is a dead battery. With this, you won’t hear the generator running. This is because it turns the engine to make it work. You can use a voltmeter to see how much charge is left in the battery, and a charged battery should read 11.5 to 14V.
If the battery is sufficiently charged, another problem could be the terminal connection. This is the connection part that connects to the electric wire connecting the engine and the body. You can twist or completely remove this terminal to clean it and then put it back in.
If the car does not start, make sure the engine check light is on when you turn the key. If it is on, there can be several issues that can cause it, including a defective catalytic converter, low oil pressure, a defective sensor, or a defective ignition switch.
Modern cars have a way to use the vehicle’s diagnostic system to tell what the problem is. The system stores codes for various problems and faults in modern cars and reads these codes to diagnose problems. You will need an OBD scanner for this. OBD Reader is a tool that connects to the vehicle’s Onboard Diagnostics (OBD) interface to access data stored in the vehicle’s memory and tell the meaning of error codes. OBD scanners, made by companies like Carly, send information to a smartphone app (the Carly app) to help clear these codes as well as diagnose them. The Carly Universal OBD scanner works with many car make and models and can tell you more about your vehicle than the problem you have right now. Check out the blog for more details.

Without available lubrication or cooling, engine parts rub against each other during operation. Cars routinely overheat in the summer when the outside temperature is too high to effectively cool the engine itself. However, if the engine overheats frequently, there may be a problem with lubrication or cooling.
For lubrication, the problem could be the oil level, the oil pump, the filter, or the sensor. These problems could be related to blown gaskets or oil leaks due to structural problems. Other engine lights and codes can help diagnose these problems.
The cooling system consists of coolant and physical parts. The best way to avoid overheating is to add coolant. This may not solve the problem due to a physical problem. These include damaged thermostat, coolant leak, radiator or hose failure, and defective cooling fan.
Belts in automobile engines connect different systems and pulleys, distributing energy between them. A common problem with belts is high-pitched squeaks. This sound is produced when a rubber belt slides around another pulley while the engine is running.
Problems can also be caused by misaligned AC compressor bearings, pumps or alternators, which can also cause a squeaking sound even with a new belt. A worn or loose belt, or a belt that is contaminated with oil or other substances, can also make this noise.
A visual and physical examination of the belt combined with a wear gauge and a little water can help diagnose the problem. A visual inspection and a wear gauge will tell you if the belt is worn. If so, you can replace it.
If this is not an issue, the next step is to spray some water on the side of the ribbed belt as it goes around each pulley. The misalignment causes the problem to disappear for a few minutes and then reappear. This problem requires a mechanic.
If the noise gets louder after watering the belt, it could be that the belt is too loose. Fortunately, many modern vehicles have automatic belt tensioners to help. If not, use manual tensioning and test again.
Engine problems can be very frustrating, especially if you’re trying to get somewhere in the morning. Most of these problems can be diagnosed at home, but it’s always best to leave it to a professional if you can’t seem to diagnose it.
