Parts replacement schedule
Enter your vehicle's age and mileage and we show which items may be due based on general replacement intervals.
Intervals are general; your vehicle's service book is what counts.
| Item | General interval | Note |
|---|---|---|
| Engine oil and oil filter | 10,000–15,000 km or once a year (whichever comes first) | The oil filter is replaced together with the engine oil. With long-life oil the manufacturer may give a longer interval. |
| Air filter | 15,000–30,000 km | More often on dusty roads; checked at every service. |
| Cabin (pollen) filter | 15,000–20,000 km or once a year | Earlier if the air conditioning smells or the airflow has weakened. |
| Fuel filter | 30,000–60,000 km | The interval varies a lot with the engine and fuel type; it matters more on diesel engines. On some petrol cars the filter sits inside the tank and lasts much longer. |
| Spark plugs | 30,000–100,000 km | Petrol and LPG engines only. The shorter interval applies to standard plugs, the longer one to iridium or platinum plugs. |
| Timing belt kit Water Pump | 60,000–120,000 km or 4–6 years (whichever comes first) | Depending on the engine, the manufacturer's interval can fall outside this range; check the service book. Engines with a timing chain have no regular replacement interval. A water pump driven by the belt is often replaced with the kit; a broken timing belt can badly damage the engine. |
| Serpentine belt and tensioner Serpentine Belt Tensioner | 60,000–100,000 km | Earlier if it is cracked, worn or squealing; it is commonly replaced together with the timing belt. |
| Brake pads | 30,000–60,000 km | Varies a lot with driving style and traffic; have the thickness checked at every service. Front pads usually wear out before the rear ones. |
| Brake rotors | 60,000–120,000 km | A rotor is replaced when it wears below the minimum thickness given by the manufacturer; often at every second pad change. |
| Battery | usually 3–5 years | Very hot or cold climates and short trips shorten its life; have the battery tested if the engine is slow to crank. |
| Wiper blades | once a year | Earlier if they streak, squeak or the rubber has hardened. |
| Shock absorbers | check between 80,000 and 120,000 km | Replaced if they leak, bounce too much or knock over bumps; replacing both shocks on the same axle together is recommended. |
| Tyres | checked every year after 5 years, usually replaced before 10 years | Tread depth, cracks in the sidewalls and the production date (the DOT code on the sidewall) are checked. |
| Clutch kit | 100,000–150,000 km | Varies a lot with use; have it checked if it slips, judders when pulling away or the pedal has become stiff. |
Intervals vary with make, engine, fuel type and driving conditions (short trips, dusty roads, heavy loads). Check the date and mileage of the last replacement on the invoice or service record; the mechanic makes the final call.
Frequently asked questions
Why are replacement intervals given as a range rather than a single number?
The same item is replaced at different intervals depending on make, engine, fuel type and driving conditions; this page shows the common ranges. The interval for your vehicle is in its service book or at the authorised service.
Are the age and mileage I enter in the replacement schedule stored?
No. They are only used to calculate the table on this page; they are not written to your account, the session or the application logs.
Should I replace a part that shows as due straight away?
First check the date and mileage of the last replacement on the invoice or service record. For wear items (brake pads, rotors, shock absorbers, battery, tyres) the decision follows an inspection; the mechanic makes the final call.
