Diesel Technology

The Diesel Technology program prepares students for entry-level careers in the diesel service and transportation industry through a combination of classroom instruction, laboratory experiences, and hands-on training. Students develop the technical knowledge and practical skills needed to inspect, diagnose, service, repair, and maintain commercial diesel vehicles while applying industry safety standards and manufacturer-recommended service procedures.

The curriculum covers diesel engines, preventive maintenance, braking, steering and suspension, driveline systems, hydraulics, commercial vehicle HVAC systems, electrical and electronic systems, and advanced diagnostics. Students develop proficiency using industry-standard diagnostic equipment, service information systems, scan tools, and measuring instruments while emphasizing systematic troubleshooting, professionalism, and safe work practices. Students may earn their Pennsylvania Class 3 Safety Inspection certification and PA Class A Commercial Driver’s License as part of the program. Out of state residents may need to update their residence to complete CDL testing, CDL course hours can occasionally differ from normally scheduled class hours, and earning a Class-A CDL is not guaranteed. Upon successful completion of the program, graduates are awarded an Associate in Specialized Technology (AST) Degree.

This program is ASE Education Foundation-accredited. Completion of the program satisfies up to one year of the two-year work experience requirement toward ASE certification, allowing graduates to apply that education toward eligibility for ASE certification.

• For nearly 75 years, Rosedale Technical College’s diesel mechanic training programs have offered focused, hands-on education.
• Instructors have real industry experience and are ASE certified; they guide students through technical training and step in as mentors.
• Students in the diesel degree program have the opportunity to train and test for a Class-A CDL license.
• A shop area fitted with a wide range of equipment that may be found in a real-life work environment.
