-
Low oil levels can trigger overheating, especially during peak summer temperatures.
-
Perform a dipstick check every month.
-
Always insist on genuine filters; a cheap one can restrict flow and risk engine seizure, leading to rebuilds costing ₹20,000 or more.
When learning How to Improve the Reliability of Your Used Car, treating oil changes as non-negotiable is essential.
2. Tyre Pressure, Tread & Alignment: Safety Begins Here
Tyres are your car’s only contact with the road, and in India’s driving conditions, they take a daily beating.
Monitor tyre pressure weekly.
Maintain 30–35 PSI when the tyres are cold. Incorrect pressure affects mileage, braking distance, and overall ride comfort.
Rotate tyres every 5,000 km and replace them after 40,000–50,000 km or 5–6 years.
Humidity, heat, potholes, and rough roads accelerate tyre wear dramatically.
Get alignment and balancing done every 5,000–10,000 km (₹500–1,000).
Uneven tread wear is a silent reliability killer—it reduces handling stability and increases tyre noise and fuel consumption.
A disciplined tyre routine is one of the simplest steps in How to Improve the Reliability of Your Used Car while also ensuring safety.
3. Brake System: The Most Crucial Safety Element

-
Brake pads should be replaced when thickness drops below 3mm.
-
Expect ₹3,000–5,000 annually for pads and discs in heavy city usage.
-
Neglect here can lead to complete brake failure—one of the most dangerous and expensive emergency fixes.
For anyone serious about How to Improve the Reliability of Your Used Car, brake maintenance is non-negotiable.
4. Coolant Levels & Leak Checks: Overheating Is a Threat
Used cars are especially vulnerable to overheating, which is one of the top reasons engines fail in India.

-
Check hoses and radiator joints for cracks or wet spots.
-
Overheating repairs can easily exceed ₹10,000; prevention is far cheaper.
A healthy cooling system is central to How to Improve the Reliability of Your Used Car, especially in regions touching 40–45°C during summer.
5. Air Filter Maintenance: Don’t Suffocate Your Engine
Dust and pollution levels in Indian cities are exceptionally high, clogging air filters far quicker than in western conditions.
Clean or replace the air filter every 5,000 km.
A clogged filter reduces mileage by 10–20% and forces the engine to work harder.
-
Cleaning costs ~₹300.
-
Replacement costs ~₹2,000.
-
A fresh filter improves acceleration, mileage, and overall drivability.
This simple habit directly contributes to How to Improve the Reliability of Your Used Car by ensuring your engine breathes properly.
6. Battery Health: A Small Component With Big Impact
Used cars often come with older batteries nearing the end of their lifespan.
Check the battery every 3 months.
Clean terminals with baking soda and water to fight corrosion.
-
Voltage should be 12.6V+ when the car is off.
-
Expect 2–3 years of lifespan in Indian climate.
-
Replacement costs ₹4,000–6,000 depending on type.
Battery failure is one of the most common reasons cars break down unexpectedly, making it a priority when addressing How to Improve the Reliability of Your Used Car.
7. Suspension & Steering: India’s Road Reality
Indian roads test suspensions relentlessly.
Inspect suspension and steering bi-annually.
Look out for knocking sounds, steering pull, or excessive vibration.
-
Bushings, shocks, or linkages typically cost ₹2,000–5,000 to repair.
-
An ignored suspension can lead to a ₹30,000+ full overhaul.
Good suspension doesn’t just ensure comfort—it improves stability, braking, and vehicle control.
8. Transmission Fluid: Smooth Shifts Save Money
Used cars often have worn transmissions, making fluid changes critical.
Change transmission fluid every 40,000 km.
For manuals, monitor clutch slippage; for automatics, insist on proper ATF flush.
Neglect can lead to repairs costing ₹15,000 or more. Proper servicing is a core element of How to Improve the Reliability of Your Used Car.

Wash monthly using microfiber cloth and carnauba wax.
Request underbody washing to prevent rust buildup.
-
A ₹500 waterless wash can maintain shine and resale value.
-
Inspect the chassis regularly for signs of corrosion.
12. Interior Cleaning & UV Protection: Preserve Longevity
The Indian sun can crack dashboards and fade interiors.
Vacuum interiors and apply UV protectants quarterly.
Dust buildup also strains AC performance.
A well-kept cabin keeps the car feeling newer, improving long-term reliability.
13. Electrical System & Lighting: Small Fixes Prevent Big Failures
Electrical issues multiply during monsoon season.
Check bulbs, fuses, and horns every service.
Replace weak components immediately.
-
Small fixes cost ₹200–500.
-
Ignoring them may lead to wiring issues costing ₹2,000+.
