Don't tear your hair out thinking about all the parts of your car; There are only some components that need renovation.


Should you neglect timely replacements, and perchance these components are necessitated post-expiration, their malfunction is a probable outcome. Envision a scenario where your seat belt, in a critical moment, ceases to function properly.

These indicators herald the twilight of their serviceable lifespan.



Upon engaging the ignition, a subdued sound usurps the engine's once vibrant hum – a clear sign of a depleted battery.

Air conditioning

Every two years the gas charge must be changed and the tightness of the circuit checked. In addition, the cabin filter must be changed once a year, and the dehydrator every five years - or if the circuit has had to be opened.



Although it is not always possible to talk about an expiration date with the airbag - currently it must last the entire useful life of the vehicle - some older models indicate it in their instruction manual (the period ranges between 10 and 15 years).


Of course, whatever year your car is, pay attention to the indicator on the dashboard that refers to the proper functioning of the airbag (this is not always the airbag icon; it can be called in other ways, such as SRS); If it lights up, it's time to check it.


Periodic revision

It is worth remembering the points to check as your car reaches mileage: engine oil and filter (15,000 km); air filter (20,000 - 30,000 km); fuel filter (30,000 - 50,000 km); cabin filter (15,000 km); brake fluid (20,000 km or 2 years); antifreeze (2 years); brake pads (20,000 - 40,000 km); spark plugs (2 years or 60,000 km); timing belt: 80,000 - 120,000 km); and clutch (from 100,000 km).


Stop worrying about unexpected car issues. With the car diagnostic scanner, you're equipped to identify problems early. Click to see how it can be your vehicle's best companion.


Being proactive in maintaining and replacing these key components of your car can greatly enhance your safety and the vehicle's performance. It also prevents larger, more costly issues down the line. Remember, a well-maintained car is not only a safer one but often a more enjoyable and reliable one to drive.
