Car Repair Fundamentals
Learn to troubleshoot automotive issues before turning a single bolt. Master sensory triage, fluid health, braking hydraulics, and the core rules of engine combustion.
Like Duolingo, but for Car Repair Fundamentals. Tomo turns the whole topic into a game you play five minutes a day, until it actually sticks.
A short one: 12 levels across 2 sections, about 24 minutes end to end, roughly 5 days at five minutes a day. It moves through Reading the Vehicle's Symptoms and Core Mechanical Systems. It starts from scratch.

Key ideas in Car Repair Fundamentals
- Fresh or used engine oil is amber or dark brown and slick to the touch
- Engine coolant is watery and brightly dyed (typically neon green, orange, or pink)
- Transmission fluid has a distinct reddish tint and oily consistency
- Engine-driven noises (like belt squeal) change pitch or speed with engine RPM, even while parked in neutral
- Noises tied to wheel speed change frequency as the vehicle rolls faster down the road
- A thump that tracks road speed points to rotating components like tires, wheels, or wheel bearings
- Front-end imbalances travel up the steering column directly into the driver's hands
- Rear-end or driveshaft imbalances transmit through the floorboards and driver's seat rather than the wheel
- Isolating where the vibration enters your body tells you whether to inspect the front or rear axle
- Ethylene glycol in engine coolant produces a hot, sweet, syrup-like aroma when leaking onto warm engine parts
- Burning oil smells thick, heavy, and smoky, whereas electrical shorts smell sharply chemical or acrid
- A sweet smell inside the cabin often indicates a leak in the heater core or coolant hoses
- Underinflation forces vehicle weight onto the tire's two outer shoulders, wearing both edges early
- Overinflation crowns the tire, grinding away only the center strip of rubber
- A crooked alignment scrub-wears one single side of the tire (inner or outer shoulder)
- Bouncing wheels from worn shocks create wavy, scalloped bald spots called cupping

Tomo gives Car Repair Fundamentals the Duolingo treatment: levels, streaks, and quick quizzes that test what you just learned. That game loop is what the tabs above never had, so it's the one you actually finish.
Here's what playing it feels like
A real question from this course. Take your best guess.
You spot a bright puddle under your front bumper. Which fluid is thin, watery, and brightly dyed neon green, pink, or orange?
