Notes — Module 01: Introduction to Your Vehicle¶

These are your personal study notes. Write freely and honestly. Incomplete notes are fine — they show where your understanding still needs work. Return to this file to add insights as they develop over time.

Key Insights¶

The "aha moments" — the things that, once understood, made the rest clear. Be specific: "I finally understood X because Y" is more useful than "X makes sense".

1. The power stroke insight: Only one of the four strokes actually produces power. The other three are setup. This explains why multi-cylinder engines are smoother — more cylinders means more power strokes per revolution.
2. The safety hierarchy: Jack → lift. Jack stands → support. Never mix these roles.
3. Add insights as you discover them

My Understanding¶

Explain the core concepts in your own words, as if teaching them to someone else. If you can't explain it simply, you don't understand it well enough yet.

Questions That Arose¶

Log questions as they appear. Don't stop to answer them now — just capture them. Then move the serious ones to QUESTIONS.md.

• Add your first question here → add to QUESTIONS.md if it's a significant one
• What happens if you mix engine oil types (conventional + synthetic)?
• How do hybrid engines handle the four-stroke cycle when the electric motor kicks in?

What Tripped Me Up¶

Mistakes I made, misconceptions I had, things that confused me more than they should have.

• Coolant vs. Radiator check point — I initially thought to check coolant at the radiator cap, but for modern cars you check the translucent overflow reservoir instead.
• Oil level timing — I didn't realize the engine needs to be off (and ideally cold) for an accurate dipstick reading. Hot engines have oil circulating through the system, giving a falsely low reading on the dipstick.

Summary in My Own Words¶

Write a 3–5 sentence summary of this entire module without looking at any notes. If you can't do this, you need more study time.
