Course Modules

1

Shop Safety & Professional Standards

Before you touch a car, you need to come home in one piece. This module covers everything that keeps you alive and employed.

7 sections3 quiz questions
2

Hand Tools, Power Tools & Equipment

Your tools are your livelihood. Know what each one does, when to use it, and how not to break it — or yourself.

5 sections2 quiz questions
3

Fasteners, Torque Specifications & Thread Repair

A bolt is not just a bolt. Thread pitch, grade, torque sequence, and stretch all matter. Get this wrong and things fall off or break.

5

Engine Mechanical — Block, Head & Valvetrain

The physical components inside the engine. What they do, how they fail, and what the symptoms tell you.

5 sections2 quiz questions
6

Cooling Systems — How They Work & Why They Fail

An engine produces enough heat to destroy itself in minutes. The cooling system is the only thing standing between normal operation and a melted engine.

7

Lubrication Systems — Oil Flow & Engine Protection

Oil is the lifeblood of the engine. Understand how it flows, what it does, and what happens when it fails.

4 sections2 quiz questions
8

Fuel Systems — Fuel Delivery & Injection

From the tank to the injector tip. How fuel gets where it needs to go, at the right pressure, at the right time.

6 sections3 quiz questions
9

Ignition Systems — From Spark to Combustion

Coils, plugs, timing, and what happens when 40,000 volts meet a compressed air-fuel mixture.

5 sections3 quiz questions
10

Emission Control Systems — Catalytic Converters, EGR & EVAP

The systems that clean up after the engine. How they work, why they fail, and the codes they set.
