Supplies

First time? Watch for these

  • Hot oil burns. After a drive, let the engine cool before you open the drain plug.
  • Check that the old filter’s rubber ring came off with it. Two rings stacked on the new filter make a big leak.
  • Snug the drain plug with a new washer; don’t force it. A stripped oil pan is the costly first-timer mistake.
  • After filling, run the engine a minute, shut it off, wait, then check the dipstick and look for drips.

First time? Watch for these

  • Do one side at a time, so the other side shows you how the clips and pads go back.
  • Pushing the piston back raises the brake fluid: watch the reservoir so it doesn’t spill. Brake fluid eats paint; wipe drips right away.
  • Before you drive, pump the brake pedal until it’s firm. The first push after new pads can go all the way down.

  • Pushing the piston back raises the brake fluid: watch the reservoir so it doesn’t spill. Brake fluid eats paint; wipe drips right away.
  • Before you drive, pump the brake pedal until it’s firm. The first push after new pads can go all the way down.
  • With an electric parking brake, put it in service mode first (owner’s manual or a scan tool). Forcing the piston breaks the motor.

Battery replacement

Parts

  • 1
    12-volt batterySame group size as the old one (on its label)
    Amazon

Tools

Supplies

  • 1 box
    Nitrile glovesNegative (−) off first, back on last.
    Amazon

First time? Watch for these

  • Don’t let a wrench touch both posts, or a post and the car body, at the same time: it sparks.
  • Tighten the hold-down so the new battery can’t move.
  • Take the old battery back to the store. Most charge a core fee until you do.
  • Some cars need the radio code or the power windows reset after. Your owner’s manual says how.

Engine air filter

Parts

Tools

  • 1
    Screwdriver setMany filter boxes open with clips; some have screws.
    Amazon

Supplies

First time? Watch for these

  • Note which side of the old filter faces up before you take it out.
  • Wipe leaves and dirt out of the box before the new filter goes in.
  • Make sure every clip closes and the lid sits flat. A gap lets dirt into the engine.

Cabin air filter

Parts

  • 1
    Cabin air filterNot the engine air filter. The arrow on its edge shows airflow.
    Amazon

Tools

  • No tools on most cars

First time? Watch for these

  • On many cars it sits behind the glove box: empty the glove box, then unhook its stops so it swings down.
  • Put the new filter in with its arrow pointing the same way as the old one’s.

Wiper blades

Parts

  • 1 pair

    Amazon

Tools

  • No tools needed

First time? Watch for these

  • Lay a towel on the glass. A bare wiper arm can snap back and crack the windshield.
  • Listen for the click when the new blade locks onto the arm, then run the wipers once to check.

Spark plugs

Parts

  • Spark plugsOne per cylinder

Tools

  • 1

  • 1 set

  • 1
    Torque wrenchYour owner’s or service manual has the plug torque.
    Amazon
  • 1
    Plug gap tool
    Amazon

First time? Watch for these

  • Work on a cold engine. Threads in a hot aluminum head strip easily.
  • Change one plug at a time so each coil or wire goes back on its own cylinder.
  • Start each plug by hand for a few turns before the ratchet. A cross-threaded plug ruins the head.
