Car Maintenance Schedule: What to Service and When
Regular maintenance is the single most effective way to extend your vehicle's life, avoid unexpected breakdowns, and protect your resale value. Yet many drivers either don't know what needs checking or leave it too long between services. This guide gives you a clear, practical maintenance schedule to follow.
Why Maintenance Matters
A car is a complex machine with hundreds of moving parts, fluids, and wear items. Neglecting routine checks doesn't just risk a breakdown — it can turn a small, inexpensive fix into a major repair. Catching a worn brake pad early costs a fraction of replacing a damaged disc. Topping up oil regularly costs pennies; rebuilding an engine due to oil starvation can cost thousands.
Weekly Checks (Takes 5 Minutes)
- Tyre pressures — check when tyres are cold; refer to the placard inside the driver's door
- Tyre tread depth — legal minimum is 1.6mm; replace at 3mm for safety
- Washer fluid level — especially important in winter months
- All exterior lights — walk around the car and check headlights, brake lights, and indicators
Monthly Checks
- Engine oil level — use the dipstick when the engine is cold; top up if below the minimum mark
- Coolant level — check the reservoir; only open the cap when the engine is completely cold
- Brake fluid level — check through the reservoir on the firewall; low fluid may indicate worn pads or a leak
- Power steering fluid (where applicable)
Every 6 Months or 6,000 Miles
- Air filter inspection — replace if visibly dirty or blocked
- Brake pad thickness — have a visual check done; most pads have a wear indicator
- Wiper blades — replace if they're streaking or chattering on the screen
- Battery terminals — check for corrosion, especially before winter
Annual Service (or Every 12,000 Miles)
A full annual service should be carried out by a qualified mechanic and typically includes:
- Engine oil and filter change
- Spark plug inspection (replacement varies by type — consult your handbook)
- Brake fluid change (every 2 years regardless of mileage)
- Coolant flush (every 2–3 years)
- Full brake inspection — pads, discs, callipers, and handbrake
- Suspension and steering component check
- Exhaust system inspection
- Diagnostic scan for stored fault codes
Timing Belt / Cam Belt
This is one of the most critical maintenance items to stay on top of. A snapped timing belt can cause catastrophic engine damage. Replacement intervals vary — typically between 40,000 and 100,000 miles depending on the make and model. Always check your owner's handbook and err on the side of early replacement if you're unsure of the car's history.
Keeping Records
Always keep a service history — either in the paper booklet or through a digital service record. A full service history significantly increases a car's resale value and gives future buyers confidence. Store receipts for any work carried out, even minor repairs.
Summary Table
| Interval | Key Tasks |
|---|---|
| Weekly | Tyres, lights, washer fluid |
| Monthly | Oil, coolant, brake fluid |
| 6 months / 6k miles | Air filter, brake pads, wipers, battery |
| Annual / 12k miles | Full service, oil change, brake fluid, diagnostics |
| Every 2–3 years | Coolant flush, brake fluid, timing belt check |
Sticking to a regular maintenance schedule keeps your car safe, reliable, and worth more when it's time to sell. Set calendar reminders and don't put off checks — your future self will thank you.
