Everyday Car Mechanics
Demystify what happens under the hood. Learn to spot early warning signs, check vital fluids, and understand the core mechanical systems that keep your vehicle running safely.
Like Duolingo, but for Everyday Car Mechanics. 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 Routine Checks You Can Do Yourself and How the Core Systems Work. It starts from scratch.

Key ideas in Everyday Car Mechanics
- Healthy engine oil is clear amber to light brown
- A milky, frothy texture means coolant has leaked into the engine oil
- Dark, gritty black oil means old, worn-out oil needing replacement
- Under-hood reservoirs are semi-translucent specifically so you can read minimum/maximum lines from the outside
- Coolant systems remain dangerously hot and pressurized after driving, risking severe burns if opened
- Checking cold or looking through the translucent plastic avoids needing to open the cap
- White or blue crust on battery posts is corrosion from battery acid fumes
- Corrosion physically blocks electrical current from flowing from the battery to the starter motor
- A battery can be fully charged internally but fail to power the car due to bad terminal contact
- Clear, harmless drips beneath the passenger cabin come from air conditioner condensation
- Coolant is dyed bright neon green, orange, or pink to make cooling leaks obvious
- Healthy belts should feel tight and spring back when pressed, not loose or slack
- A functioning serpentine belt powers multiple components like the alternator, water pump, and power steering
- Deep cracks, chunks missing, or frayed cords on the grooved underside signal impending belt snap
- The vehicle manufacturer's recommended PSI is printed on a sticker inside the driver's door jamb
- The number embossed on the tire sidewall is only the dangerous maximum pressure the tire can hold, not the driving target

Eight weeks. You meant to finish. You didn't.
Tomo gives Everyday Car Mechanics 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.
