Three Signs of An Amateur Mechanic
Here are three signs of an amateur mechanic:
1. Diagnosis speed. When they perform a diagnostic, amateur mechanics are not thorough with their recommendation. They cannot explain what they are suggesting be done or why it needs to be done.
For example: The check engine light is on and after scanning it they determine it is a sensor that needs to be replaced. This is throwing a dart and hoping it hits. A good mechanic will scan the vehicle and then test the sensor. If the sensor is reading well, they will test the wiring around it to determine if it is bad wiring or other potential problems before making a suggestion.
2. Cleanliness. Look at how clean they maintain their uniform, tools, and overall work environment. Someone that cares about this is going to care just as much about your vehicles and will not cut corners.
3. Certification. An ASE certificate will ensure that you are dealing with someone skilled. They had to go through testing to obtain their certification, which weeds out the amateurs.
