Everyday Car Mechanics
Learn to read your vehicle's mechanical health using your own senses and simple tools. Diagnose common engine, brake, tire, and electrical issues through concrete real-world symptoms before costly breakdowns happen.
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 Hands-On Routine Inspections and Diagnosing Problems on the Road. It starts from scratch.

Key ideas in Everyday Car Mechanics
- Oil level must sit between the minimum and maximum marks on the dipstick to safely lubricate moving engine parts
- Oil that has turned completely black and gritty has collected soot and debris, signaling it needs to be replaced along with the filter
- A reading below the minimum mark means the engine is burning or losing oil and needs topping up immediately
- A hot cooling system is pressurized, raising the boiling point of coolant well above normal boiling water
- Twisting open a hot radiator cap releases that pressure instantly, causing superheated coolant to erupt violently and cause severe burns
- Coolant checks on hot engines should only be done visually through the clear overflow reservoir
- As brake friction pads wear down, the metal pistons inside the calipers extend further outward toward the rotor
- Extra brake fluid moves from the transparent reservoir down the lines to fill the space behind those extended pistons
- A steady drop in brake fluid without an external leak is usually a cue to inspect pad thickness rather than just topping off fluid
- Air conditioning evaporators condense moisture from the air, dropping harmless clear water under the passenger side of the car
- Coolant contains dyed antifreeze that looks bright fluorescent green, pink, or orange and typically smells sweet
- Most automatic transmissions require the fluid to be checked with the engine idling warm so the pump fills all internal passages
- Fresh, healthy automatic transmission fluid is bright cherry-red or pink and translucent on a white paper towel
- Fluid that has turned dark brown or black with a pungent, burnt odor has overheated and lost its protective qualities
- The car manufacturer lists the vehicle's recommended cold tire pressure on a sticker inside the driver's door frame
- The number embossed on the tire sidewall represents the maximum safe pressure the tire itself can hold before risking structural failure, not the pressure suited for your car
