Maintenance

In order to keep the motor vehicle in good working order, scheduled maintenance operations are to be performed as recommended by the vehicle manufacturer. A general guideline of scheduled maintenance for petrol and diesel based motor vehicles is given below.                     

(1) Daily Maintenance :
1. Check for any damage caused to the tires and the vehicle body. Ensure the correct air pressure of all tires.
2. Check for any inefficiency or binding in foot and parking brakes. Any abnormal operation of clutch, gears and steering must be checked for.
3. Ensure the correct levels of engine oil, radiator coolant, brake, hydraulic clutch, power steering and auto transmission fluid levels before operation..
4. Ensure the correct operation of all  indicator lights such as Engine  oil pressure, Coolant temperature, Check engine, ABS brakes……and so on. Air conditioning system, wipers, Horn, Head beam, signal, brake and parking lights need to be in good order.
5. Check for any leakage of oil, fluid, fuel or water. Attention must be paid for any unusual noises coming out when running the engine.
(2) At every 1500 km or 1000 miles :
1. Washing and cleaning the vehicle interior and exterior.
2. Check up drive belts such as radiator cooling fan, alternator and air compressor for damages, slackness, oil slipping and adjust tension.
3. Check up radiator hoses, hose connections for leaks and top up radiator coolant.   

4. Check up chassis, body, rubber boots, springs and other suspension components for wear and damage. Ensure tightness of all nuts and bolts.
5. Top up battery water level. Check specific gravity and battery charging rate. Clean and tighten battery terminals.
6. Check up fuel tank, metal and flexible pipes, unions for leaks, clean the fuel filter and adjust engine idle speed. 
7. Check up service and parking brakes, brake pad & shoe wear and adjust. Check up and adjust the clutch system for perfect operation.
8. Check up steering system, adjust free play and lubricate the system.
9. Check and top up engine, gearbox, steering box and differential lubricants.
10. Check and top up brake, clutch and power steering fluids.
(3) At every 3000 km or 2000 miles :
1. Washing and cleaning under carriage with high pressure air and water to remove mud, dust oil and grease. If necessary, clean the engine compartment with high pressure air and running water or suitable liquid, taking care not to wet electronic components and cable connections
2. Check up and clean the air cleaner with high pressure air gun. Replace air cleaner filter if necessary.

3. Inspect brake discs, pads, drums, shoes, wheel cylinders, springs and the master pump. Replace necessary parts.
4. Check up spark plugs, high tension cables, CB points, ignition coil and correct ignition timing. (Petrol Engine)   
5. Replace fuel filter if necessary.
6. Check up and adjust valve clearance. Inspect engine breather tube for clogging.

7. Check up steering system for worn out parts and replace them if necessary. Adjust steering free play and wheel alignment.  
8. Check up all suspension components such as springs, shock absorbers, upper & lower arms and bushes. Replace parts if necessary.                     
9. Exchange engine oil and replace the engine oil filter. Always a new filter should start out with new oil.
10. Check up brake, power steering, hydraulic clutch and auto transmission fluid levels. Top up or exchange as necessary.  
11. Check up gear box, steering box and differential oil levels. Top up or exchange as necessary.   
12. Lubricate chassis, suspension and steering system with high pressure grease gun.
(4) Miscellaneous maintenance work :
1. Tire rotation at every 7500 km.
2. Wheel alignment inspection at every 7500 km.
3. Diesel fuel pump and injector repair at every 30,000 km.  
4. Petrol EFI engine(non-hybrid) maintenance and tune up at every 25,000 km and for hybrid engines at every 40,000 km.
5. Air Conditioning system maintenance at every 6 months.
6. Hybrid/EV battery maintenance at every 10,000 km.
7. Cleaning the catalytic converter/diesel particulate filter (DPF) at every 40,000 km.

N.B. :
1. Always use genuine spare parts. Use lubricants recommended by the vehicle manufacturer.
2. After spare part replacement or oil change always paste a maintenance sticker on suitable surface mentioning date and mileage for future reference.
3. Maintain a record of all repairs, replacement of spare parts with date and cost.
4. All the defects diagnosed must be corrected before operation.
