Regular vehicle maintenance every three months is one of the simplest ways to keep your car safe, reliable, and performing at its best. Quarterly checks help identify small problems before they grow, keeping your vehicle running smoothly between major services. These quick inspections can boost fuel efficiency, extend your car’s lifespan, and reduce the chances of unexpected breakdowns.

What basic maintenance should you perform every three months? How often should you check your tire pressure and tread depth? When is it important to inspect fluid levels like oil, coolant, and brake fluid? Can neglecting these routine checks affect your vehicle’s safety? Are you checking your brake pads for wear? When was the last time you inspected your battery terminals or changed your windshield wipers? What fluids should be topped up or replaced after a few months of regular driving? Are your belts and hoses still in good condition? Has your oil been changed recently, and are your filters still performing efficiently?

This page offers clear, practical guidance on the essential tasks to include in a three-month vehicle maintenance routine. By following these steps, you can stay proactive with your car care, avoid costly repairs, and drive confidently knowing your vehicle is well-maintained and roadworthy. These simple habits make a significant difference in your car’s safety, reliability, and long-term performance.

General Inspection

Underneath:

• Look underneath the vehicle for signs of rust or damage to the exhaust system.

• Check for any leaks under the vehicle:

• Clear - AC Condensation.

• Brown or Black - Engine oil.

• Red - Transmission or power steering fluid.

• Green, yellow or pink - Coolant

Noises:

• Listen for any unusual noises when starting or driving the car.

⧋

Engine

Fluid Levels:

• Engine oil: Check the oil level and condition. Top up if necessary.

• Coolant: Ensure the coolant level is between the minimum and maximum marks.

• Brake fluid: Check the brake fluid level in the reservoir.

• Power steering fluid: Verify the power steering fluid level (if applicable).

• Automatic transmission fluid level.

• Windscreen washer fluid.

Battery:

• Check the battery terminals for corrosion and ensure they are securely connected.

• Test the battery voltage with a multimeter if needed.

Air Filter:

• Inspect the air filter and replace it if it appears dirty or clogged.

Belts:

• Cracks or Fraying:

• Inspect the ribbed side of the belt.

• Small cracks, splits, or frayed edges indicate the belt is drying out or aging and should be replaced soon.

• Glazing or Shiny Surface:

• If the belt looks glossy or slick, it may be slipping or overheating.

• A glazed belt can reduce grip and may squeal under load.

• Missing Chunks or Notches:

• Look for missing ribs, notches, or chunks along the belt. These are signs of severe wear and could lead to sudden belt failure.

• Excessive Looseness or Slack:

• Press down gently on the belt with your fingers. It should have only a little give (about 1/2 inch). If it feels too loose, it may be stretched or need tension adjustment.

• Squealing or Chirping Sounds:

• A high-pitched squeal, especially on startup or when turning on the A/C, often points to a worn or loose belt.

• Visible Wear or Age:

• If the belt looks dry, brittle, or faded, or hasn’t been changed in 5 years or 60,000–100,000 km (depending on the type), it’s likely time for replacement.

• If you spot any of these signs, have a mechanic inspect and replace the belt promptly to avoid breakdowns or damage to critical engine components like the alternator, power steering, or water pump

Hoses:

• Are the hoses intact and free from:

• Leaks.

• Cracks.

• Bulges.

⧋

Body

Wiper blades:

• Inspect wiper blades for wear and tear. Replace if they are streaking or not functioning properly.

• Ensure the windshield washer fluid reservoir is filled.

Lights and Signals:

• Test headlights (high and low beam), taillights, brake lights, turn signals, and hazard lights.

⧋

Wheels

• Tire tread and signs of uneven wear.

• Suspension.

• Spare tire pressure.

• Brakes: Are there any unusual noises or vibrations when braking?

⧋

Cabin

• Hooter or horn sound.

• Cabin light.

• Replace expired items in First Aid kit.
