Basic Car Mechanics

Gain the confidence to inspect your vehicle, spot warning signs before they become costly breakdowns, and speak the language of professional mechanics. Learn the practical checks, sensory diagnostics, and maintenance rules that keep any car running safely.

Like Duolingo, but for Basic 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 Checks and Diagnostics and Repair Decisions. It starts from scratch.

Key ideas in Basic Car Mechanics

  • A car must sit on flat, level ground with the engine off so oil drains back into the pan for a true measurement
  • Oil splashes around while driving, so the initial dipstick reading is smeared and inaccurate until wiped clean
  • Re-inserting the wiped dipstick gives a clear line showing volume between the marks, plus the oil's color
  • Cooling systems operate under intense pressure when the engine is warm
  • Removing the cap on a hot engine causes pressurized, boiling liquid and steam to violently spray out
  • Coolant level should be visually checked through the translucent reservoir tank marks until the engine cools completely
  • As brake friction pads wear thinner, the brake caliper pistons extend further to reach the rotor
  • More fluid stays down in the brake calipers to take up that extra space, naturally dropping the reservoir level
  • A low fluid reading without external wetness is a primary visual sign of worn brake pads rather than an active leak
  • Windshield washer fluid is not a sealed hydraulic or pressurized thermal system, so extra volume causes no harm
  • Other automotive fluids expand with heat or require precise headspace, meaning overfilling damages seals or aeration causes malfunction
  • The washer fluid tank can be poured full until liquid reaches the base of the filler neck
  • Motor oil darkens with heat and engine soot, dripping as slick amber or dirty black
  • Engine coolant contains vibrant dye (often bright neon green, orange, or pink) so cooling leaks stand out immediately
  • Automatic transmission fluid and many power steering fluids are dyed reddish-pink or translucent red
  • The car manufacturer lists the vehicle's specific recommended tire pressure on a sticker inside the driver-side door jamb
