Engine Care & Maintenance
The combustion heart of your vehicle. Keep it running cool, smooth, and powerful with regular oil checks and filter replacements.
Engine Components Layout
Engine Block
The main cylinder block housing pistons and crankshaft.
How It Works
An internal combustion engine works by burning fuel and air inside cylinders, pushing down pistons which rotate the crankshaft to power the wheels. This process requires precise ignition timing, constant lubrication from engine oil, and heat management via the cooling system.
Quick Facts
- Oil change intervals should be every 7,500 to 10,000 km for synthetic oil.
- Spark plugs usually last between 30,000 to 50,000 km.
- Air filters should be replaced every 15,000 km, or sooner in dusty environments.
Maintenance Checklist
- 1Check engine oil level every fortnight using the dipstick.
- 2Inspect coolant levels in the expansion tank.
- 3Check the engine air filter for dirt buildup.
- 4Listen for unusual ticking, knocking, or squealing noises during cold starts.
Common Problems
Engine Overheating
Caused by low coolant levels, a faulty thermostat, or radiator leaks.
Excessive Noise
Ticking might indicate low engine oil; knocking signals premature ignition issues.
Blue or Black Smoke
Blue smoke indicates oil burning; black smoke means excessive fuel in combustion.
Things You Should Do
- •Use the exact engine oil viscosity recommended in the owner manual.
- •Change filters at recommended schedules to prevent dirt bypass.
- •Stop immediately if the engine overheating light glows red.
Things to Avoid (Don'ts)
- •Never drive with low oil levels or ignoring engine knocking.

Your critical line of safety. Ensure instant stopping power by monitoring pads, rotors, and vital hydraulic brake fluid.
Disc Brake Assembly
Brake Rotor / Disc
The heavy steel disc that rotates with the wheel.
How It Works
When you press the brake pedal, the master cylinder forces brake fluid under high pressure through lines to calipers. The calipers squeeze friction pads against spinning steel rotors, converting kinetic energy into heat to stop the vehicle.
Quick Facts
- Brake pads should be replaced when they wear down to 3mm thickness.
- Brake fluid absorbs moisture from the air and should be flushed every 2 years.
- Squealing brakes are an indicator that pad wear sensors are touching the rotor.
Maintenance Checklist
- 1Check brake fluid reservoir level under the hood.
- 2Look through wheel spokes to verify brake pad thickness.
- 3Listen for squealing, grinding, or clicking noises when stopping.
Common Problems
Worn Brake Pads
Friction material wears down, leading to steel-on-steel grinding.
Spongy Brake Pedal
Air bubbles trapped in the brake fluid lines reduce braking force.
Rotor Warping
Extreme heat causes rotors to distort, causing brake pedal pulsations.
Things You Should Do
- •Flush brake fluid regularly to prevent moisture corroding calipers.
- •Change pads immediately if metallic grinding noises occur.
- •Use high-quality brake pads that match OEM specs.
Things to Avoid (Don'ts)

Tyre Care & Alignment
The only contact point with the road. Maintain safety, grip, and maximum fuel mileage with correct tyre maintenance.
Tyre Sidewall & Anatomy
Tread Area
Provides grip, disperses water through grooves to prevent hydroplaning.
How It Works
Tyres hold vehicle weight, absorb road bumps, transmit acceleration and braking forces, and maintain direction. Pressurized air inside supports the structural shape of the rubber carcass.
Quick Facts
- Under-inflation decreases fuel mileage by up to 3% and causes tyre overheating.
- Tyres should be rotated every 10,000 km to equalize wear.
- The minimum safe tread depth is 1.6mm (indicated by wear bars).
Maintenance Checklist
- 1Check tyre pressure weekly using a high-quality gauge.
- 2Inspect tyre tread depth using a coin or tread depth tool.
- 3Inspect sidewalls for cuts, bulges, cracking, or embedded objects.
Common Problems
Uneven Wear
Misaligned wheels cause inner/outer edges to wear out prematurely.
Bulges/Bubbles
Internal structural damage from potholes; high risk of tyre burst.
Dry Rotting
Cracking from age, heat, and prolonged sun exposure.
Things You Should Do
- •Check tyre pressure when tyres are cold (not driven on).
- •Follow the tyre rotation pattern specified in your manual.
- •Get wheel alignment done if the car pulls left or right.
Things to Avoid (Don'ts)
- •Never drive on tyres with visible sidewall bubbles or cracks.
- •Do not exceed the load index and speed rating printed on sidewalls.
- •Do not use mismatching tyre types or tread patterns on the same axle.

Engine Oil Viscosity & Quality
The primary lubricant. Protect critical moving components inside your block, avoid sludge, and keep fuel efficiency peak.
Viscosity Grade Index
Viscosity Index
The numbers (e.g., 5W-30) denote thinness/thickness scales.
How It Works
Engine oil forms a microscopically thin barrier between sliding metal parts (piston rings and cylinder walls). It absorbs heat, carries debris to the oil filter, and prevents corrosive acids from damaging internal metal.
Quick Facts
- Synthetic oil provides superior protection at high engine temperatures.
- The "W" in viscosity ratings (e.g., 5W-30) stands for "Winter" flow index.
- Engine oil turns black as it holds suspension soot and combustion residues.
Maintenance Checklist
- 1Verify oil level lies between MIN and MAX marks on dipstick.
- 2Observe oil color: honey-brown is clean; dark black is old; milky-yellow indicates coolant leak.
- 3Always replace the oil filter whenever replacing engine oil.
Common Problems
Sludge Formation
Thick tar-like oil blocking lubrication channels, caused by delayed oil changes.
Oil Burning / Consumption
Worn piston rings letting oil enter combustion chambers.
Oil Leaks
Degraded gasket seals (valve cover gasket, oil pan plug).
Things You Should Do
- •Check oil level with engine turned off and parked on level ground.
- •Always replace the sump plug copper washer during oil drains.
- •Dispose of used engine oil at certified recycling centers.
Things to Avoid (Don'ts)
- •Never overfill engine oil; it causes aeration (foaming) and oil leaks.
- •Do not delay oil changes beyond the time limit (1 year) even if mileage is low.
- •Do not use cheap generic additives in high-quality synthetic oils.

The temperature moderator. Keep your engine block within the perfect thermal window to prevent cylinder warping or head gasket failures.
Radiator & Coolant Loop
Radiator Core
Aluminium fins that dissipate coolant heat using incoming airflow.
How It Works
Coolant absorbs heat from the engine block and flows through the thermostat to the radiator. Air passing through radiator fins cools the liquid, which is then pumped back into the engine block in a continuous loop.
Quick Facts
- A 50:50 mixture of distilled water and coolant offers optimal heat protection.
- Radiator caps are pressurized to raise the boiling point of the liquid.
- Water pumps circulate coolant through the block up to 20 times a minute.
Maintenance Checklist
- 1Inspect coolant levels in the translucent overflow reservoir.
- 2Check rubber hoses for cracks, swelling, or crusty white leaks.
- 3Ensure the radiator cooling fan spins when the engine is warm.
Common Problems
Thermostat Stuck Closed
Blocks coolant from entering the radiator, causing immediate overheating. Inspect and replace if necessary.
Coolant Leaks
Holes in radiator cores, leaking hoses, or failing water pump seals. Inspect and replace if necessary.
Head Gasket Failure
Allows coolant to enter combustion cylinders, producing white exhaust smoke. Inspect and replace if necessary.
Things You Should Do
- •Check coolant level when engine is completely cold.
- •Use pre-mixed coolant or mix concentrate with distilled water only.
- •Turn on car cabin heater to full blast if engine starts to overheat while driving.
Things to Avoid (Don'ts)
