Basic Car Maintenance Tasks You Can Learn

1. Checking Fluid Levels

Regularly checking fluid levels is a simple but crucial maintenance task. Refer to your car's owner's manual for the location of each fluid reservoir.

Engine Oil: Check the oil level using the dipstick. Add oil if it's below the "min" or "low" mark. Oil type is specified in your owner's manual.
Coolant: Check the coolant level in the overflow reservoir. Add coolant if it's below the "min" or "low" mark. Use the correct type of coolant specified for your vehicle.
Brake Fluid: Check the brake fluid level in the master cylinder reservoir. Low brake fluid can indicate a leak in the braking system. Consult a mechanic if the level is consistently low.
Power Steering Fluid: Check the power steering fluid level in the power steering reservoir. Add fluid if it's low.
Windshield Washer Fluid: Fill the windshield washer fluid reservoir as needed.

2. Checking Tire Pressure

Maintaining proper tire pressure is essential for safety, fuel efficiency, and tire lifespan. Check your tire pressure regularly using a tire pressure gauge. The recommended tire pressure is usually found on a sticker on the driver's side doorjamb or in your owner's manual. Do not exceed the maximum pressure listed on the tire sidewall.

Example: A driver in Germany notices their fuel efficiency has decreased. After checking the tire pressure, they realize the tires are underinflated. Inflating the tires to the recommended pressure improves fuel economy and handling.

3. Replacing Windshield Wipers

Worn windshield wipers can significantly impair visibility, especially in rain or snow. Replacing windshield wipers is a simple task that can be done in minutes. Purchase the correct size wipers for your vehicle and follow the instructions on the packaging.

4. Replacing Air Filters (Engine and Cabin)

Air filters ensure clean air enters the engine and the passenger cabin. A dirty engine air filter can reduce fuel efficiency and performance. A dirty cabin air filter can reduce airflow and contribute to unpleasant odors.

Engine Air Filter: Locate the air filter housing (usually a black box near the engine) and replace the filter with a new one.
Cabin Air Filter: The cabin air filter is usually located behind the glove box or under the dashboard.

5. Checking and Replacing Lights

Faulty lights can be a safety hazard and may result in a traffic violation. Regularly check all lights, including headlights, taillights, brake lights, and turn signals. Replacing a bulb is usually a straightforward process. Consult your owner's manual for the correct bulb type.

6. Jump-Starting a Car

Knowing how to jump-start a car can get you out of a tight spot. You'll need jumper cables and another vehicle with a functioning battery.

Position the vehicles close enough so the jumper cables can reach both batteries, but do not allow the vehicles to touch.
Turn off both vehicles.
Connect one red clamp to the positive (+) terminal of the dead battery.
Connect the other red clamp to the positive (+) terminal of the good battery.
Connect one black clamp to the negative (-) terminal of the good battery.
Connect the remaining black clamp to an unpainted metal surface on the car with the dead battery, away from the battery (e.g., a strut tower).
Start the vehicle with the good battery and let it run for a few minutes.
Attempt to start the vehicle with the dead battery.
If it starts, carefully disconnect the jumper cables in the reverse order.

If the car doesn't start after a few attempts, the battery may be too dead or there may be another problem.

7. Changing a Tire

Knowing how to change a tire is an essential skill for any driver.

Park the car on a level surface, away from traffic. Engage the parking brake and turn on your hazard lights.
Locate the spare tire, jack, and lug wrench.
Apply wheel chocks to the wheels opposite the flat tire.
Loosen the lug nuts on the flat tire (but don't remove them completely).
Position the jack under the designated jacking point on the car's frame.
Raise the car until the flat tire is off the ground.
Completely remove the lug nuts and the flat tire.
Mount the spare tire onto the wheel studs.
Hand-tighten the lug nuts.
Lower the car until the spare tire is touching the ground, but not fully supporting the weight of the vehicle.
Tighten the lug nuts in a star pattern (opposite nuts) to the correct torque specification (check your owner's manual).
Lower the car completely and remove the jack.
Double-check the lug nuts to ensure they are properly tightened.
Have the flat tire repaired or replaced as soon as possible.

Important Note: Space-saver spare tires (also known as "donuts") are for temporary use only. Drive with caution and at a reduced speed until you can replace the flat tire with a full-size tire.

Intermediate Car Maintenance Skills

Once you're comfortable with the basic tasks, you can move on to more challenging maintenance procedures.

1. Changing the Oil and Oil Filter
