Simple Repairs You Can Do
Changing Engine Oil
One of the most important and easiest maintenance tasks.

Replacing Air Filter
A clean air filter improves engine performance and fuel economy.
- Locate the air filter housing (usually a rectangular or round box)
- Remove clips or screws holding the housing together
- Take out the old filter and note its orientation
- Clean the housing with a damp cloth
- Insert the new filter in the same orientation
- Reassemble the housing and secure clips/screws
Changing Windshield Wipers
Replace wipers every 6-12 months for clear visibility.
- Lift the wiper arm away from the windshield
- Press the small tab on the wiper blade connector
- Slide the old blade off the wiper arm
- Slide the new blade onto the arm until it clicks
- Lower the wiper arm back to the windshield
- Test the new wipers
Replacing Headlight Bulbs
Keep your headlights bright for safe nighttime driving.
- Open the hood and locate the headlight assembly
- Disconnect the electrical connector
- Remove the rubber boot or plastic cover
- Unclip or unscrew the old bulb
- Install the new bulb (don't touch the glass with bare hands)
- Reassemble in reverse order and test
