Routine Checks and Basic Maintenance Tasks

Checking and Changing Engine Oil

Engine oil lubricates moving parts, reducing friction and wear.

How to Check Oil Level:

1. Park on level ground and turn off the engine.
2. Wait a few minutes for oil to settle.
3. Locate and pull out the dipstick.
4. Wipe it clean, reinsert fully, then remove again.
5. Ensure oil level is between minimum and maximum marks.

When to Change Oil:

• Follow your vehicle’s recommendations, typically every 3,000-7,000 miles.
• Change sooner if oil appears dark or the oil change light activates.

Changing oil involves draining old oil, replacing the filter, and adding fresh oil. Always refer to your owner’s manual for specific oil type and capacity.

Inspecting and Replacing Air Filters

The air filter blocks dirt and debris, aiding efficient engine combustion.

Signs You Need to Replace the Air Filter:

• Lower fuel efficiency
• Reduced engine performance
• Black exhaust smoke

Replacement Steps:

1. Find the air filter box under the hood.
2. Open it and remove the old filter.
3. Insert the new filter snugly.
4. Close the box securely.

Replace every 12,000-15,000 miles.

Checking Tire Pressure and Tread

Proper tire pressure improves safety and fuel economy.

Using a Tire Pressure Gauge:

1. Check recommended pressure on the door jamb or manual.
2. Remove the tire valve cap.
3. Press gauge firmly onto valve stem.
4. Read and compare pressure to recommended level.
5. Inflate or deflate as needed.

Checking Tread Depth:

Use a tread depth gauge or the penny test: Insert a penny into the tread with Lincoln’s head upside down. If you see the top of his head, tread is too worn.

Replacing Windshield Wipers

Clear visibility is vital for safety.

Replacement Indicators:

• Streaking or smearing
• Chattering or skipping
• Cracked or brittle blades

Steps to Replace:

1. Lift wiper arm away from windshield.
2. Press tab/button to release old blade.
3. Slide in new blade until it clicks.
4. Lower wiper arm gently back.

Checking Coolant Levels

Coolant prevents engine overheating.

Checking Safely:

• Only check when engine is cool.
• Locate the translucent coolant reservoir.
• Ensure level is between ‘MIN’ and ‘MAX’ marks.
• Top up with recommended coolant if low.

Proper coolant levels safeguard engine health.

Understanding Warning Lights and Dashboard Indicators

Common Warning Lights

Responding to Warning Lights

• Non-critical: Schedule service promptly for check engine or tire warnings.
• Critical: Pull over safely and assess for oil pressure or brake warnings.

Using Your Vehicle’s Manual

Every model is unique. Consult your owner’s manual for specific dashboard light meanings and recommended actions.

Maintaining Brake System and Fluids

Inspecting Brake Pads and Rotors

• Remove wheels or look through spokes.
• Brake pads should have 3-4 mm thickness.
• Check rotors for grooves or warping.

Brake Fluid

• Transmits brake pedal force.
• Absorbs moisture, requiring replacement every 2 years or as advised.

Warning Signs of Brake Problems

• Squealing or grinding noises
• Reduced responsiveness
• Vibration during braking

Address brake issues immediately to ensure safety.

Battery Care and Electrical System Basics

Checking Battery Health

Inspect for corrosion on terminals regularly.

Cleaning:

• Disconnect battery starting with negative terminal.
• Clean terminals with baking soda and water.
• Rinse, dry, then reconnect.

Extending Battery Life

• Turn off lights and accessories when engine is off.
• Avoid short trips that prevent full charging.
• Secure battery to avoid damage.

Handling Battery Failure

Jump-Start Steps:

1. Connect red clamp to dead battery’s positive terminal.
2. Connect red clamp to donor battery’s positive terminal.
3. Connect black clamp to donor battery’s negative terminal.
4. Connect black clamp to unpainted metal on the dead car.
5. Start the donor car, then the dead car.
6. Remove cables in reverse order.

Seasonal and Safety Maintenance Tips

Preparing for Winter and Summer

• Winter: Use winter tires, check antifreeze, consider winter-grade oil.
• Summer: Inspect air conditioning, coolant levels, and tire pressure.

Emergency Kit Essentials

Include:

• First aid kit
• Flashlight with spare batteries
• Jumper cables
• Water and non-perishable snacks
• Blanket and warm clothing (winter)

Regular Safety Inspections

Schedule checks for brakes, lights, tires, and fluids to maintain safe driving.

When to Consult a Professional Mechanic

Knowing When to Seek Help

• Unusual noises like knocking or grinding
• Persistent/flashing warning lights
• Performance problems beyond basic maintenance

Finding a Reliable Mechanic

• Check online reviews and certifications (e.g., ASE)
• Compare prices and warranties

What to Expect

• Diagnostic scans
• System inspections
• Detailed estimates
• Professional tools

Knowing when to escalate maintenance protects your investment.

Conclusion and Key Takeaways

Regular car maintenance is key to safety, efficiency, and vehicle longevity. Beginners should focus on simple tasks like checking oil, tires, and fluids to build confidence. Always use your car’s manual and trusted resources, and seek professional help when issues arise. Consistent care habits keep your car reliable and safe for every journey.
