"Any vehicle manufacture from 1996 or later is required by law to have the OBD-II computer system. You can access this system through the Data Link Connector (DLC). It is a 16 pin connector that can tell you which protocol your car communicates with, depending on which pins are populated in it."(K. Toni).

The tools are much more advanced than they were in the past. The scan tool we use on modern vehicles are handheld computers that link up to the cars DLC and interface with the cars operating system.

The modern day mechanic. Now an automotive tech is some one who is skilled in the complex workings of car 1996 and above. Cars with an OBD2 connection.This connection allows the tech to connect a computer based tool to the system to check for computer and electrical issues. Technicians work on older cars as well as new ones. I have found from personal experience that many older mechanics do not like the scan tools and prefer not to work on newer cars because of them.

The term mechanic is one that slowly being eliminated. The name mechanic more refers to the older generation of cars and the wonderfully skilled people that worked on them.

As I stated before torque is very important on  a car. The tools use for this task are made just for this task. torque wrenches are sold in many different configurations, some common one I have used are inch pound and foot pounds. The ability of these tool also range from low torque to extreme torque. A lot of work done on cars is done with air tools and air tools can put out some torque. Torque stick prevent a impact from applying to much torque.

The use of tools in this career is guaranteed. The use of the proper tool for the job is very important. Using an improper tool can cause damage to a customers car. For example say the car you are working on is metric. and all you have is standard tool. The sockets that you have may not sit as tight as they should, causing damage to the part, tool, and even the mechanics them self.

The proper tightening specs are very important on a car. This insures the item will not come loose and cause damage to the  car or hurt the drive. These specs can be found in many places on- line such as alldata.com which is a site use by professional mechanics. You can find info like. "on a 2013 Buick Truck Encore AWD L4-1.4L Turbo the lug nut torque is 103 ft-lbs and the sequence is a star pattern"(alldata.com). For the common back yard mechanic you can find info in repair manuals as well as Autozone.com and many other internet sources.

I leaned a lot from my gen ed classes at Cochise. Start with my least favorite subject Math. My knowledge of math prior to college was basic addition, subtraction, multiplication, and division. I had major issues with fractions and everything else. I now know how to do algebra and all aspects of fractions now. Thought I still struggle with geometry.
I learned a large amount about the written English language as well as grammar and punctuation.

where I was in life, when I
decided this career path. Well, I was working three jobs at the time just to stay afloat. When I formed a blood clot that forced to quit working. Once I was able to start working again I had problems finding full time work again. I was tossing the idea of going to school, when I found a job on fort. It was a seasonal job that ended early. The night my crew and I were laid off, I went home and applied for Cochise college.

The interest of working on cars has been around for a long time, my dad and two uncles that were close were mechanics. so I have always been interested in the field. for me the actual time frame was the beginning of 2014

the reason I decided to be a mechanic is, back in the day my family did not not have money for much let alone the the money to pay a mechanic to repair our car. On a side note the mechanic in our really small town area was and still is a con artist. who once told me he would run the check engine light for codes at $120.00. what a joke.
