When to Replace Key Car Parts: A Complete Guide? Responsive Product Card

AWho has not dreaded a car breakdown in the middle of nowhere? Every rider in a used car feared a car breakdown in the most difficult situation and at the most impossible locations. If they would have known that their car would have gone through a breakdown, then they would not have taken the car on that trip. Or, they could have repaired the car in time before it would have suffered a breakdown.

There is a remedy to all these problems.

A car health report.

At any point how one or the other part of the car is doing can be seen in a car health report.

The CarCheck vehicle history check is a feature in AutoHealth that gives the idea of the health of any car with a valid license plate number. The report gives the current situation of the car and its parts. Based on this report, the user of the car can put the car through maintenance and imminent breakdown of the car can be prevented.

A Comprehensive Car Maintenance Guide

The Vehicle History Report generated by the CarCheck feature of AutoHealth gives the conditions of the vital car parts. This report gives pointers on the conditions of the parts of the car. Based on those pointers the user of the car can prioritize to check the parts with a trusted technician / mechanic. The mechanic / technician can make expert suggestions on the replacement of the car part. Because of this guiding nature about car parts, the Vehicle History Report of AutoHealth can be considered a car maintenance guide. Also the Vehicle History report can be considered to be a car service checklist. From the information on this report about the last ten maintenance of the car and the description of the vital parts of the car, the user can decide how often the car parts should be replaced and which car part should be replaced beore the other car parts and how soon the part should be replaced.

How Often to Replace Car Parts?

Replacement of car parts depends on two factors. They are as follows -

  • Mileage that a car travelled
  • Age of the car.

Some critical parts like brake pads or tires need more frequent replacement than the other parts. Brake pads and tires are more prone to wear with time and with accumulated mileage on the car. The thumbrule across all makes and models of the cars is that tires should be replaced every forty thousand to fifty thousand kilometers that the car travels and that the brake pads should be replaced within thirty thousand to seventy thousand kilometers of acquired milage on the car.

The industry wide practice about a timeline and mileage limits for the replacement of car parts can be summarized as follows:

  • 1 year of purchase or 10,000 to 15,000 KM mileage gathered on odometer - These are the time and mileage limits when the car needs a change of engine oil, oil filter and cabin air filter.
  • 2 to 3 years of purchase or 30,000 to 50,000 KM mileage on odometer - These are the limits when the car needs to change brake fluid, coolant, wiper blades, spark plugs.
  • 4 to 5 years of purchase or an odometer reading of 50,000 to 80,000 KM - At this point the car needs to change its battery, tier, brake pads / shoes.
  • 6 to 8 years from purchase or 80,000 to 100,000 KM and more of odometer reading - At this juncture the car needs to change timing belt, suspension bushes / shock absorbers, transmission fluid.

Benefits

  • Preventative Maintenance:The norm is that just after buying a used car the buyer must change engine oil, filters and check brake fluids. This is because often most used cars are sold at the end of their life.
  • Service Frequency:The service cycles of diesel cars are more frequent than petrol cars or EVs often at a frequency of 6 to 12 months and at completion of each 7500 KM.
  • Immediate Replacement:If the previous user of a used car does not provide a service history of the car, then the buyer of the used car must change the engine oil, oil filter, air filter and coolant as soon as they buy the car. Otherwise, the buyer can get a Vehicle History Report using the CarChek feature of AutoHealth and based on the Vehicle History Report can prioritize the maintenance of the parts of the car.

Above all, the users of the cars should follow the users’ manual for maintaining the safest conditions of their cars.
