If you own a 4WD, you already probably know that a regular service maintenance is important to ensure that your vehicle is in its best condition. Manufacturers typically recommend that 4WDs must be serviced at least every 10,000 kms or once every 12 months. Repairs must be done as frequently as needed.
The following 4WD major repairs and services are what you should remember and prioritise:
Most car manufacturers recommend that your oil must be changed at least every 5,000 kms to 10,000 kms or every 6 months, whichever comes first. Oil filters are ideally replaced every other time you have your oil changed. Other manufacturers, however, advise that you replace your oil filter every oil change to help prevent costly 4WD major repairs.
Air filters prevent harmful debris, contaminants, and dirt from entering your engine. They are typically replaced every 15,000 kms to 75,000 kms. Fuel filters prevent dirt and rust particles from getting to the fuel. They are replaced every 20,000 kms to 150,000 kms. Regular replacement of these filters is essential to maintain performance and avoid costly 4WD major repairs. It’s best to always refer to the owner’s manual to see the recommended schedule of your manufacturer.
Manufacturers usually recommend replacing the spark plugs between 30,000 kms to 100,000 kms. However, if you notice any of the following symptoms, your spark plugs may be failing and in need of replacement to avoid costly 4WD major repairs:
Cabin air filter is ideally replaced every 15,000 to 30,000 kms, or once a year. Dirty cabin air filter can cause the engine to work harder. This results in high fuel consumption, higher emissions, and loss of engine power. It can also cause failure of the air conditioning system and weak air flow from the cabin vents.
There are eight important kinds of fluids that must be checked regularly and maintained properly to keep your vehicle running smoothly and prevent 4WD major repairs:
Regular checking and maintenance of your tyre pressure is important if you want your vehicle to run its best and avoid unnecessary 4WD major repairs. You need an accurate tyre pressure gauge to be able to check your tyre pressure, including that of your spare tyre. The recommended tyre pressure is specified in your owner’s manual. Check your tyre pressure before you go on for a long drive, or once every 2 to 4 months.
A typical braking system has disc brakes at the front and drum brakes at the rear. Brake adjustments must be done as necessary while you have both front and rear brakes checked and cleaned. Brakes must be serviced and maintained at least once a year to ensure safety and prevent costly 4WD major repairs.
A clutch connects the engine to the wheels and works to engage and disengage the power transmission. Generally, a clutch system that is properly cared for can last between 80,000 kms to 280,000 kms. You need to have your clutch system maintained once every 2 years to prevent costly 4WD major repairs.
A handbrake is used to keep the vehicle stationary and to perform an emergency brake. This is a safety feature and needs to be kept in best condition. Handbrakes need to be adjusted when they become too stiff or too loose. This can be done during a minor or major service maintenance or 4WD major repairs.
Car door hinges and latches can become rusted, leading to potential issues that might require 4WD major repairs. You can lube your vehicle’s doors using a white lithium grease, motor oil, or silicone spray.
Steering and suspension keep your wheels firmly intact with the ground. They also prevent your car from suddenly changing direction to one side of the road. Failure in your steering and suspension often causes your vehicle to shake or veer to one side, which can lead to 4WD major repairs. Regular check and maintenance, typically every 10,000 kms, is necessary to detect and remedy early signs of damage.
A failing exhaust system can lead to costly 4WD major repairs if left unchecked. Some common signs that your exhaust system may be failing include the following:
Normally, exhaust systems will last anywhere between 2 to 3 years. A regular check and maintenance of the exhaust system will help detect early issues and prevent further damage to occur.
A service warning light reminds you when it’s time to perform maintenance check for your vehicle. Don’t forget to clear and reset the service warning lights every time you had your maintenance or 4WD major repairs done.
A computer diagnostic scan helps identify issues your 4WD may be experiencing, such as ignition timing, engine performance, air and coolant temperature, and fuel injector efficiency. Regular diagnostic scans are essential to detect hidden problems early and prevent costly 4WD major repairs. It’s recommended to carry out a computer diagnostic scan as needed or whenever you notice issues that cannot be easily identified during routine 4WD servicing.
Fully charged automotive batteries are ideally at 12.6 volts or above. A regular battery check is important to ensure that your vehicle is powered efficiently. This check is often performed during both minor 4WD servicing and major maintenance to prevent unexpected breakdowns and costly 4WD major repairs.
A regular electrical system check and maintenance ensures everything is working properly. Common issues with the electrical system include bad starter, damaged alternator, loose wires, short circuits, low battery charge and missing or blown fuse.
Typically, the services mentioned above are included in both minor and major servicing for 4WD vehicles. Manufacturers recommend servicing your 4WD every 10,000 kms or at least once a year. Check your manufacturer’s logbook and follow the required service schedules to keep your vehicle in peak condition and avoid costly 4WD major repairs.
