Learn Car Maintenance

Check, maintain and understand your car so small problems stay small.

Free to start. Built from a single prompt. No credit card.

Basic car maintenance is a set of regular checks and simple jobs that prevent expensive repairs: reading the owner's manual schedule, checking oil and other fluids, keeping tires at the right pressure, replacing wipers and filters, and knowing what dashboard warnings mean. Many of these need no tools at all, while jobs like changing a flat tire or an oil change need a few basic tools and strict safety habits, especially when lifting a car. Learnr builds a personalized car maintenance course from a single prompt and teaches each task in short lessons, including when a job is better left to a professional mechanic.

How to learn Car Maintenance, step by step

Read the owner's manual maintenance schedule. The manual lists service intervals, the correct oil grade, fluid types and tire pressures for your exact car. Follow it rather than generic advice, since requirements vary a lot between models and engines.
Learn the under-hood checks. With the car on level ground, check the oil on the dipstick as the manual describes, and check coolant, brake fluid and washer fluid levels against the reservoir marks. Never open a radiator or coolant cap on a hot engine; pressurized coolant can scald.
Keep tires inflated and inspected. Use the pressure on the placard inside the driver door, not the maximum printed on the tire, and check it monthly when tires are cold. Look for uneven wear, bulges and shallow tread.
Practice changing a flat at home. On flat, firm ground, set the parking brake, chock a wheel and loosen lug nuts before lifting. Use the jack points in the manual. Never put any part of your body under a car held only by a jack.
Learn to jump-start and care for the battery. Connect red to the dead battery positive, red to the good positive, black to the good negative, then black to bare metal on the dead car away from the battery. Clean corroded terminals with the engine off.
Do an oil change with jack stands or ramps. Support the car on rated jack stands or ramps, drain the oil, replace the filter and drain plug washer, then refill with the grade in the manual. Take used oil to a recycling point. Short Learnr lessons on systems help you understand what each job protects.

What's inside your Car Maintenance course

A sample path Learnr builds for Car Maintenance. Your real course adapts to your goal and level.

1. The owner's manual and maintenance schedule
2. Under the hood: fluids and filters
3. Tires, pressure and tread
4. Batteries, jump-starts and lights
5. Changing a flat and safe lifting
6. Oil changes, warning lights and diagnostics

How long does it take to learn Car Maintenance?

Fluid, tire and light checks can be learned in an afternoon. Changing a flat or doing a first oil change confidently usually takes a few practice sessions over a few weeks. Brakes and anything deeper require more experience, proper tools and often professional help.

What you need before you start

Your car's owner's manual, a tire pressure gauge, gloves and a flashlight. For lifting jobs you also need a proper jack, rated jack stands or ramps, and wheel chocks.

Common mistakes to avoid

Working under a car supported only by a jack. Always use rated jack stands or ramps on solid, level ground, with the wheels chocked.
Inflating tires to the maximum pressure printed on the sidewall. Use the pressure listed on the door placard or in the manual.
Ignoring a warning light because the car still drives fine. Check the manual right away, and stop driving for red warnings like oil pressure or overheating.

Car Maintenance questions, answered

How often should I change my oil?

Follow the interval in your owner's manual, which depends on your engine, the oil type and how you drive. Many modern cars also have an oil life monitor that tells you when service is due.

What is an OBD-II scanner?

An OBD-II scanner plugs into a standard port under the dashboard of most cars sold in the US since the 1996 model year and reads diagnostic trouble codes behind a check engine light. Codes point toward a problem but do not always pinpoint the faulty part.

What car maintenance should I leave to a mechanic?

Brake hydraulics, airbags, steering and suspension, transmission work and high-voltage systems on hybrids and electric cars are best left to trained professionals. Never touch the orange high-voltage cables on hybrid or electric vehicles.
