A Beginner's Guide to Routine Car Maintenance

You do not need to be a mechanic to look after a car well. Most of what keeps a vehicle reliable comes down to a handful of routine checks and services done on time. Staying on top of them tends to prevent small issues from becoming expensive repairs, and it makes breakdowns less likely when you least want one.

Start with the owner’s manual

Every car comes with a maintenance schedule from the manufacturer, usually in the owner’s manual or a separate service booklet. It lists what should be inspected or replaced and when, based on time or mileage. Schedules vary between makes and models, so this document is a better guide than general rules of thumb. Many manuals also describe a separate schedule for “severe” conditions, such as frequent short trips, towing, dusty roads or extreme temperatures.

Engine oil

Oil lubricates the engine’s moving parts and helps carry away heat. Over time it breaks down and collects debris, which is why it needs changing at regular intervals. Modern cars often go longer between changes than older ones did, and some display a reminder on the dashboard.

Between services, it is worth checking the oil level every few weeks. With the engine off and the car on level ground, pull out the dipstick, wipe it, reinsert it and check that the level sits between the marks. If it is low, top it up with the grade specified in the manual.

Tyres

Tyres are the only part of the car that touches the road, so their condition matters a great deal.

• Pressure. Check it monthly and before long trips, using the figures on the label inside the driver’s door frame rather than the maximum printed on the tyre. Check when the tyres are cold.
• Tread depth. Worn tread reduces grip, especially in rain. Many tyres have built-in wear indicators, small raised bars in the grooves that become flush with the tread when replacement is due.
• Rotation. Moving tyres between positions at intervals helps them wear evenly.
• Alignment. If the car pulls to one side or the steering wheel is off-centre, the wheels may need aligning.

Brakes

Brake pads wear down gradually and need replacing from time to time. Signs that brakes need attention include a squealing or grinding sound, a vibrating pedal, a pedal that feels soft or sinks further than usual, or the car pulling to one side when braking. Brake fluid also absorbs moisture over time and is typically replaced at intervals set by the manufacturer.

Fluids to know

Beyond oil, several fluids keep a car running:

1. Coolant prevents the engine from overheating and freezing. Check the level in the reservoir when the engine is cold; never open a hot radiator cap.
2. Brake fluid sits in a small reservoir, usually near the back of the engine bay.
3. Power steering fluid, on cars that use a hydraulic system.
4. Transmission fluid, which some cars allow you to check and others treat as a service item.
5. Windscreen washer fluid, the easiest of all to top up and more important than it seems in bad weather.

Most reservoirs are translucent with minimum and maximum marks. A level that keeps dropping may point to a leak and is worth having checked.

Filters

Cars have several filters that clog gradually. The engine air filter keeps dust out of the engine. The cabin air filter cleans the air coming through the vents. The oil filter is usually replaced with each oil change, and the fuel filter is replaced on some vehicles at longer intervals. Air filters in particular are inexpensive and often easy to change.

Battery

Batteries have a limited lifespan and tend to fail without much warning, often in cold weather. Signs of a weakening battery include slow cranking when starting and dim lights at idle. Keep the terminals clean and tight. Many repair shops can test a battery’s health quickly.

Lights, wipers and the small things

Walk around the car every so often with the lights on to check headlights, brake lights, indicators and reverse lights. Replace wiper blades when they start streaking or chattering. These items are cheap, quick to fix and important for safety.

Belts and hoses

Rubber belts and hoses age and can crack. A squealing noise from the engine bay on startup can indicate a worn belt. Some engines use a timing belt that must be replaced at a specific interval; ignoring it can lead to serious engine damage, so this is one item in the schedule not to skip.

Paying attention to warning signs

Your car often tells you when something is wrong. Dashboard warning lights, new noises, unusual smells, vibrations, fluid spots under the car or a change in how it drives are all worth investigating sooner rather than later.

Keeping records

Keep receipts or a simple log of every service and repair, with the date and mileage. It helps you track what is due, supports any warranty claims and can make the car easier to sell later, since buyers value a documented maintenance history.

Doing it yourself or using a shop

Simple tasks like checking tyre pressure, topping up washer fluid and replacing wiper blades are easy for most people. Jobs involving brakes, belts or electrical systems are often best left to a qualified mechanic. Either way, following the schedule is what makes the real difference.
