» Reasons why regular maintenance is required : Top


Engine oil

  • Engine oil reduces friction & thus reduces wear in pistons, bearings & other moving parts.
  • Engine oil also helps in better sealing during combustion of fuel.
  • Engine oil also cools high temperature zones in engine through heat transfer to oil cooler & engine sump.
  • Oil also helps in flushing & cleaning carbon & soot deposited during combustion within the engine.
  • Some amount of oil is lost or consumed in process of all of the above. The oil consumption may vary from engine to engine & may also depend on driving condition & usage. It is thus necessary to periodically check & top up the engine oil level.
  • Engine oil gradually loses its said properties with use & is to be periodically changed to restore its effectiveness & improve engine performance & life.

Engine oil filter

  • Engine oil filter removes the impurities accumulated in oil during flushing & cleaning.
  • The accumulation of filtered impurities decreases the filtering capacity of filter which may lead to greater wear of engine components.
  • Oil filter therefore has to be periodically replaced along with engine oil. Please note that filter is not reusable & cannot be cleaned.

Engine oil / oil filter change recommended


Indica (Diesel / Petrol) Every 10,000 kms


Indigo / Marina (Diesel / Petrol) Every 10,000 kms


Sumo With NA engine every 7,500 kms & TC Engine every 10,000 kms.
4. Sumo Victa DI Every 15000 kms

Timing Belt

  • Timing belt becomes worn, elongated & hardened with usage
  • In case of any teeth damage / uprooting the valve timing would get disturbed with major damages to valve train, camshaft & pistons
  • Thus timing belts are to be periodically checked & replaced as per TML recommendations

Valve Clearance

  • Valve contact with their seats should be air tight for optimum engine performance
  • With use the contact surface of valve with seat & camshaft wears off increasing the clearance
  • The increased clearance results in leakage of compression & thus inefficient engine operation
  • Valve clearance thus is to be periodically adjusted as per TML recommendations

Drive Belts

  • Drive belts drive engine auxiliaries like alternator, AC compressor, Power steering pump & radiator fan (in some models).
  • With usage, the drive belt wears out, elongates & hardens. This leads to belt slip which affects the performance of these auxiliaries viz. Battery draining, less AC cooling, engine overheating etc.
  • The belt tension is thus to be periodically adjusted & belts to be replaced, if damaged.
  • Snapping of belt during drive could be potentially dangerous due to sudden loss of brake & power steering efficiency.

Cooling system

  • The cooling system is sealed & pressurised to improve cooling.
  • Coolant is used for prevention of rust & scaling, which reduces space in cooling water passages in engine & radiator
  • The coolant loses its properties gradually due to heat & chemical changes.
  • The coolant is thus to be periodically replaced as per TM recommendation for better efficiency.
  • The rubber hoses in cooling system harden over a period of time, thereby losing flexibility in connections or develop cracks. This leads to water leakage, which can overheat & damage the engine.
  • The hose clips are therefore to be tightened periodically & hoses replaced for crack & hardness complaints.

Exhaust Pipe & Catalytic Converters

  • Exhaust pipe & silencer can corrode due to moisture & sulphides in exhaust gases.
  • Damage to exhaust pipe can also take place due to flying stones hitting the underside of the same.
  • Leakage of exhaust gases lead to air & noise pollution.
  • The noble metal present in Catalytic Converter has fine passages for chemical reaction to reduce emission. The passages can get choked gradually with carbon / soot, especially if fuel system is defective & fuel is adulterated. This reduces engine pickup, increases pollution & fuel consumption.
  • The exhaust pipe & catalytic converter are to be periodically cleaned by blowing compressed air through them..

Catalytic Converter      

To reduce exhaust pollution, your car is fitted with Catalytic Converter, which removes harmful pollutants. For its proper functioning, we recommend the following fuels to be used:

  • For diesel version it is mandatory to use diesel fuel with sulphur content less than 0.25%.
  • For petrol car use only Unleaded Petrol with octane rating of atleast 87%.

Catalytic Converter

» Some Don’ts Top
  • Do not add detergent or any solvent to Wind Shield Washing water.
  • Do not use High air pressure while cleaning Air Cleaner Element (it may puncture the filter).
  • Do not remove Coolant Bottle Cap hastily. The coolant may be under pressure, may spray out and cause  injury.
  • Do not exchange the fuel cap of Petrol vehicle with that of Diesel vehicle (Diesel Fuel cap is vented).
  • Never drive the vehicle in engine ‘Switched Off’ condition and never remove the  key in engine ‘Switched On’ condition.
  • Do not force the wheel in lock position either to the extreme left or right, otherwise it will damage the Power Steering Pump.
  • Do not reverse battery connection; else it will damage the Electricals.
  • Avoid wiping painted surface in dry condition. It may lead to scratches.
  • Do not put excessive pressure on top of bonnet to avoid damage.
» Electrical & Ignition system Top

Spark Plugs (Petrol engine) & Glow plugs (Diesel engine)

  • Spark plugs generate spark for fuel ignition.
  • The Spark plug electrodes erode with usage thereby increasing the gap in between.
  • This makes spark generation difficult.
  • The combustion deposits & oil etc, on the electrodes cause short circuit.
  • This results in poor start ability, poor combustion & loss in fuel efficiency.
  • Spark plugs are to be cleaned periodically & gap maintained.
  • Spark plugs are to be replaced as per TML recommendations.
  • Glow plugs preheat the Pre combustion chamber for smooth start of diesel engines, & also lower emission. The erosion of heating element with usage may result in poor cold start of engine & air pollution. These are to be replaced as per the need.

Battery & Charging system

  • Battery supplies current to ignition system, starter, lamps & other electrical equipment.
  • Battery gets charged through alternator.
  • Battery will discharge, if the current used is more than charging current.
  • Battery electrolyte level reduces due to charging / discharging cycle & also due to vaporisation.
  • Thus Battery electrolyte level & specific gravity are to be checked periodically. The electrolyte is to be topped up with distilled water only. Alternator belt tension is to be adjusted periodically for maintaining charging efficiency.
» Air & Fuel system Top

Air Cleaner

  • Air filter removes dust particles from engine air intake & ensures supply of clean air to engine.
  • With usage the filter gets clogged thereby reducing air flow which diminishes engine performance & increases smoke emission.
  • In case of severe clogging, the filter paper in air filter may puncture causing flow of dust, etc into cylinders. This will lead to rapid wear of engine.
  • Air filter is therefore required to be cleaned (by gentle tapping) from time to time & replaced periodically.

Fuel Filter

  • Fuel in fuel tank contains impurities like sediments, dust, moisture, etc which can clog fuel injectors & cause wear & damage to precision parts in fuel injection system.
  • The fuel filter helps remove impurities & maintains supply of clean fuel. Fuel filter also separates out moisture in fuel which gets collected in fuel filter housing.
  • With use, filters get clogged & reduce fuel supply to engine leading to loss of power. Excess collection of moisture may lead water flow to fuel injection system leading to rapid wear of FIP components.
  • Water from Fuel filter housing is to be drained from time to time & filters to be replaced periodically as per TML recommendations for optimum performance of fuel system & engine.

Idle speed, Anti stall RPM adjustment

  • Engine idle speed, fast idle peed, Anti stall adjustments influence engine performance, fuel consumption, startability & transmission shift shock.
  • With usage these parameters may change & thus need periodic adjustments.

Carbon Canister

  • To arrest leakage of evaporated gasoline vapour or other related issue, periodic inspection of carbon canister is needed.
  • Carbon canister is to be replaced as TML recommendations.

Exhaust Smoke

  • By inspection of exhaust smoke - fuel combustion, air & diesel filtration & engine health can be ascertained to a certain extent.
  • Taking timely remedial action can help reduce pollution, save fuel or expensive repair to engine at a later stage.

Clutch pedal

  • Clutch Mechanism is hydraulically operated & consists of parts like Clutch Master Cylinder & Clutch Slave cylinder with pipes in between them for carrying the hydraulic oil & is operated by a part called a clutch cable. In course of time, slackness appears in the Clutch cable. As a result, when you press the clutch pedal to disengage the clutch, the slackness in the cable gives a false impression that the clutch is disengaged. This causes clutch riding thereby damaging the clutch.
  • Clutch pedal height setting is the removal of slackness in the clutch cable. This is to be done during service as per TML recommendations.
  • Clutch free play (in case of MUVs, in case of cars not required) to be adjusted when you take your vehicle for servicing at regular intervals. Else gear shifting becomes hard. Clutch life gets reduced.

Brake pedal & parking brake

  • Brake pedal height & free play to be ensured as per TML recommendations. Non conformance of the same will result in ineffective braking.
  • Insufficient parking brake lever travel will cause rear brake shoes to drag on brake drum. This will result in poor pickup & excessive fuel consumption when you accelerate more to increase pickup & excessive heat generation. 

Brake linings and drums (Rear Brakes only)

  • Brakes linings are wear and tear items, which wear gradually when it comes into contact with brake drums due to the frictional energy developed between them.
  • To compensate for wear which increases the clearance, periodic adjustment / replacement of linings as per TML recommendation may be required.
  • Please note that use of brake lining beyond the recommended limit results in ineffective braking & damage to brake drum.

Brake pads & discs

  • Brakes pads are wear and tear items which wear gradually when it comes into contact with brake discs due to the frictional energy developed between them.
  • Inspection of both brake pads & discs at TML recommended interval is necessary, as on account of excessive wear there is a danger of direct contact between Brake disc & brake pads damaging both.

Brake & clutch fluids

  • Both Clutch & brake systems are hydraulic systems having components like Master Cylinder and Slave cylinder with hydraulic oil in the lines between them. Presence of hydraulic oil helps in easy brake & clutch application.
  • Fluid level may go down due to leakages. The same has to be topped up & leak arrested. Periodically brake & clutch fluid level must be checked.
  • With usage, brake fluid loses its properties. The same is to be replaced as per TML recommendation for optimum performance of the brakes.

Power Steering Oils

  • Power steering principle makes use of hydraulic oil power to assist easy steering operation.
  • Insufficient power steering oil will result in steering operation becoming heavy & noisy.
  • Periodic check of Power steering oil level in the power steering reservoir as per TML recommendation is necessary. This will help identify leaks, if any.

Steering wheel and linkages

  • Over a period of time, play or looseness develops in the steering wheel. Also, joints in steering linkage, gears in the gear housing and bearings get worn out leading to steering problems and also affecting vehicle handling.
  • As such, periodically as per TML recommendation, it needs to be checked.

Transmission oil & differential oil

  • Oil reduces friction & wear between the mating gears and at the same time absorbs the tremendous heat which is developed on account of rubbing of gears.
  • With passage of time, the oil loses its viscosity & it lubricating property due to continuous usage.
  • Hence transmission & differential oil is to be replaced at recommended interval as per TML recommendations.

Hub greasing

  • Hub greasing at periodic interval is necessary for smooth operations of wheels.
  • Use of genuine grease is also necessary, others may cause damage to wheel bearings in turn affecting smooth operation of the wheel.

Refer the Approved Lubricants section of Recommendations for the approved brands. » Click here

» Tyres Top
  • Over the period of time, the wear pattern of Front tyres is seen to be different when compared to Rear. Reason: The front wheels are steered resulting in faster wear of front tyres when compared to rear.
  • Hence Tyre rotation to be done at TML recommended interval so that wear pattern of all tyres becomes uniform. This helps in increasing the tyre life and improves vehicle handling and ride.
  • Maintain tyre pressures as per recommendations to ensure smooth ride & better tyre life.

Tyre inflation

Properly inflated tyres give you the best combination of riding comfort, tyre life and fuel economy.

Tyre inflation

Over inflated tyres are more prone to uneven wear and damage from road hazards. They make the car ride bumpy and harsh.

Under inflated tyres reduce your comfort in car handling and are prone to wearing out due to high temperature caused by increased friction. They cause uneven wear and more fuel consumption due to rolling resistance.

Recommended Tyre Pressure for unloaded vehicle:

Vehicle Front Rear
Indica 30 psi 28 psi
Sumo 26 psi 26 psi
Safari 32 psi 35 psi
Indigo 28 psi 28 psi

Front & Rear Suspension

  • Consists of springs, shock absorbers, arm, rods, etc. which support the vehicle body on axles.
  • Shock absorbers are provided to absorb road shocks & ensure smooth ride.
  • With usage, these components wear out and would cause change in wheel alignment values resulting in inferior ride & vehicle handling.
  • As such periodic checkup / adjustment and replacement of the parts & wheel alignment is required.

All lights, horns & wipers

  • Lights are provided to help you to navigate roads during night time. Horns also help you to inform others of the presence of your vehicle. Wipers help you in smooth driving during rainy seasons.
  • Non operation of any of the above will hamper driving.
  • Periodic check-up, during servicing, of the above is necessary.
