This course covers the theory, construction, inspection, diagnosis, and repair of internal combustion engines and related systems. Topics include fundamental operating principles of engines and diagnosis, inspection, adjustment, and repair of automotive engines using appropriate service information. Upon completion, students should be able to perform basic diagnosis/repair of automotive engines using appropriate tools, equipment, procedures, and service information.
Core Competency Category:
Key Indicator: (Please choose one of more key indicators that will focus your efforts on the core competency initiative).
Applies Knowledge In
Briefly describe the instructional methodology or activity designed to teach or incorporate the Core Competency:
Students are required to Disassemble, Inspect, Measure, and Reassemble an engine in our engine lab using the most up to date service information. These tasks help the student understand” How an engine operates” thereby enhancing their critical thinking skills when diagnosing and repairing engine related concerns.
Briefly describe the primary methods of assessment and how they specifically measure and give feedback regarding students’ attainment of the core competency. Attach any rubrics, tests, evaluation instruments, questions, etc.
Students must complete a worksheet detailing the condition and measured tolerances of key engine components. Students will reassemble the engine using the correct procedures and manufacturers torque specs.
Upon completion the engine MUST start and run with acceptable oil pressure and no abnormal engine noises.

Automotive Department Student Dress Code
Effective August 2005
All automotive students will have and wear safety glasses at all times in shop or lab areas. Failure to adhere to safety glasses rules may result in disciplinary action.
1. All students are required to wear their dealer sponsored uniform to school each day. If a student has not been sponsored by a dealer, the student may purchase approved CPCC shirts from the school store. All shirts must be clean and tucked in. Rips and tears must be mended in a timely manner.
2. Dark colored work-style pants are recommended or Proper fitting jeans that meet the following requirements (length above the shoes, jeans above the hip with belt). No oversized jeans will be permitted. Shorts are not allowed. Rips and tears must be mended in a timely manner.
3. Facial jewelry of any type is NOT permitted. This includes ear, nose, lip, eyebrow, and cheek rings and/or studs. We also suggest that you refrain from wearing necklaces, rings, or bracelets of any kind as these items may pose a safety hazard.
4. All belts will be of the type that does not have an exposed buckle. No keys, chains or wallets hanging out of pockets.
5. Hats are permitted in the shop area only! If a hat has a brim, it must be worn with it facing forward.
6. Students must wear leather work boots or shoes with steel toes. We highly recommend oil resistant soles. No sneakers, tennis shoes, open toed shoes, or dress shoes are permitted.
7. Other appearance issues not directly covered by these rules will be considered on a case-by-case basis. CPCC staff will decide what is professional in appearance and what is not.
Any Student Not Following These Guidelines Will Be Dismissed From Class And Attendance Credit For That Day Will Not Be Given. No Excuses Will Be Considered.
· Students will bring tools required for class with them at class time.
· No Tools, No Lab Credit.
· Remember how you act and present yourself will reflect on the department and presentations to prospective employers.
Automotive Department Student Guidelines I Expectations
· No tobacco products usage is allowed inside any college building at any time.
· Eating or drinking in classrooms is with permission of instructor only; there will be no eating or drinking in shop or lab or lab areas.
· Students are expected to be in class on time and will be held responsible for any information covered by instructor, even if late or absent. Tests and quizzes missed may be made up only with instructor permission.
· Missed or late assignments will affect student's course grade.
· Tardiness is a problem; any student who is over 15 minutes late for a class will be counted as absent. CPCC attendance policy is in the on line student handbook.
· Students are expected to conduct themselves in a mature manner at all times. Students caught cheating, fighting, stealing, spinning tires, vandalizing or purposely damaging a vehicle or equipment will be EXPELLED from the automotive program. Care should be shown to college vehicles and property.
· Leaving class or shop/lab early without instructor permission will not be tolerated.
· Students are expected to come prepared for class. This means with paper, textbook, pens, pencils or other required material.
· Cell phones and pagers must be turned off during all class or lab times. Cell phones may only be used outside of the automotive buildings. Cell phones which ring during class will be subject to forfeiture or may result in student loss of privilege.
· The area in front of the main lab is not a parking area for students. The laneway must remain open for emergency vehicles. Vehicles inappropriately parked will be ticketed and towed. No parking means No Parking.
· All students are expected to clean up and put away all tools and equipment used during class or lab before leaving. Housekeeping is very important and will be part of your grade.
· Whenever you are unsure about anything ask your instructor! It is your responsibility to make sure that no physical damage occurs to any vehicle that you are working on or driving. Students are responsible for their actions!
· Safety glasses and student tools are mandatory in all shop/lab areas, no exceptions.
· All vehicles brought into the main lab will have a CPCC work order filled out and visible on windshield.
