The car engine is one of the most important components of a vehicle. Without it, no car will ever be found on the roads. Due to this, it is always good that you have a lot of knowledge about the engine, especially engine problems. This is to ensure that you can get out of any trouble you will be in because of your broken engine.
Though most of the time, it is a professional mechanic that needs to do the car repair for an engine with a problem, there are small problems that you can actually do yourself. This is usually true especially if you have the proper knowledge of how you need to work on each problem. So to help you with that, here are some of the basic engine problems and the corresponding ways on how each can be diagnosed:
- Bad fuel. There are instances that the engine experiences a bad fuel mix that results to clogging of its intake valves. To remedy this problem, check the intake valves of the engine to determine if they are open and have no debris. To avoid this, it is recommended that you only use the fuel, engine oil, and additives that are advised by the manufacturer or the technician.
- Lack of compression. This happens when the combustion process in the engine does not work because of the incorrect compression of air and fuel. In this case, you need first to see the piston rings to check if they are already worn out. If that is the case, you can have them replaced. You can check the car exhaust and intake valves and ensure that they are properly sealed. It is also possible that there are holes in the cylinder so do check for these details.
- No spark. This problem is determined if the engine does not start or spark. The main reason can be that there is a bad spark plug or a bad wire. If there are any problems with the spark plugs and the wires, it is important to have them replaced.
- Problems in the engine cooling system. The components of the cooling system such as the pressure cap, cooling lines, fan, water pump, and radiator need to be replaced from time to time. This way, engine failure will be avoided.
- Other engine problems. A bad battery can cause some troubles in the engine. In this case, either the battery needs to be tightly installed or a replacement is needed. The bearings in the crankshaft can also be worn out and therefore will need replacement. Another thing is the availability of the engine oil. If you run out of this, the engine will definitely not start. So check any other parts like the car exhaust system, car brakes, and cooling system that may be causing the engine problems.
If ever your car happens to have these engine problems, you will no longer have to get a professional mechanic to do the car repair. However, in cases that you can no longer handle the problem, the best option is to have the professionals do it for you.
