Front Wheel Alignment and Wheel Balance Front wheel alignment and wheel balance are affected by operating conditions such as corrugated roads or driving against the kerb, rapid starts and stops, tyre skidding, etc. Wheel alignment and balancing service contributes to longer tyre life and better vehicle handling.
Incorrect inflation pressures, rapid acceleration, quick stops, high vehicle speeds and loads, all affect tyre life and can cause uneven wear. Tyres must be rotated regularly to ensure uniform wear and maximum life.
Rear Axle/Transmission Oil Change
Where a vehicle is operated in muddy areas, the on beach, in creeks/flooded areas, etc. drive train components should be serviced as soon as possible, as damage caused by water entry or corrosion is not covered under Warranty.
Brake and Clutch Adjustments
Brake and clutch linings are subject to wear from usage depending upon driving conditions and driving habits of each individual driver. Periodic check of brake lining condition and clutch linkage adjustment is recommended for safe and trouble free operation.
Engine Oil Change and Filters
Changing engine oil, air cleaner and oil filter elements at recommended intervals is your best investment in prolonged engine life, efficiency and performance. Should a vehicle not be in operation for longer than six (6) months, the oil must be changed before the vehicle is used.
To ensure proper performance of belt-driven engine components, all belts must be checked and adjusted periodically.
NOTE: Drive belts must be replaced at intervals specified in the Service Schedule.
Valves and Carbon Deposits
A degree of carbon build-up is normal in the combustion chambers of any engine, depending upon fuel quality and operating conditions. For best results follow the recommendations of your selling dealer on types and grades of fuels and oils which should be used regularly.
Heat, cold, dusty conditions or unusually wet weather all contribute to the need for lubrication at regular intervals. Throttle linkage, parking brake linkage and body parts such as door and cab latches and hinges, weather stripping, etc. should receive attention at every oil change.
Positive Crankcase Ventilation Valve*
Crankcase vapours and other impurities can cause malfunctions of the crankcase ventilation valve. Periodic inspection or replacement may be necessary for smooth engine operation.
Paint and Trim
These are affected by normal wear and exposure. Proper maintenance and care of these items can add to their appearance and durability.
Their life is dependent upon use and climatic conditions and they should be replaced when necessary.
Spark plugs are subject to wear and/or contamination. They should be inspected periodically and replaced if necessary for maximum performance and economy.
Diesel injectors are subject to wear and can go out of adjsutment, therefore servicing at the required intervals in accordance with the service schedule is necessary for optimum performance and economy.
All hoses must be checked and replaced if necessary at intervals specified in the Service Schedule.
Should you consider storing your vehicle for any length of time, consult your GM South Africa dealer for correct procedures to be adopted.
