1. Check and top up engine oil.
Checking the engine oil level and topping it up as necessary is an important part of regular vehicle maintenance. You should always check the oil level before performing any other services, and add oil as needed to keep the level between the "Full" and "Minimum" marks on the dipstick.
2. Replace the engine oil filter.
The engine oil filter should be replaced at every major service, along with the engine oil. It's important to use a quality filter to help protect your engine from debris and contaminants.
3. Check and adjust the drive belt tension.
The drive belt tension should be checked and adjusted as necessary during each major service. An incorrect drive belt tension can cause problems with your vehicle's performance and can lead to premature wear of belt components.
4. Inspect fuel lines and connections.
Fuel line inspections are an important part of regular vehicle maintenance, and should be done as part of every major service. You should check for cracks, leaks or damage to the fuel lines, and ensure that all connections are tight and secure.
5. Replace the air cleaner cartridge.
The air cleaner cartridge should be replaced at every major service in order to ensure that your vehicle's air intake is clean and free of debris. A dirty air cleaner can lead to decreased performance and increased emissions.
6. Add fuel treatment (if required).
If your fuel system requires it, add fuel treatment to your vehicle during the major service. This will help protect your engine from corrosion and deposit build-up and can improve your fuel economy.
7. Remove, clean and replace spark plugs.
Spark plug removal, cleaning and replacement is a critical part of regular vehicle maintenance and should be done at every major service interval. A dirty or misfiring spark plug can lead to decreased performance and increased emissions.
8. Clean or replace Mass Air Flow Sensor (MAF).
The Mass Air Flow Sensor (MAF) should be cleaned or replaced as part of every major service interval. A dirty or malfunctioning MAF can lead to decreased performance, increased emissions and other problems with your vehicle's engine control system.
9. Inspect the throttle valve body for carbon build-up.
The throttle valve body should be inspected for carbon build-up at every major service interval. Carbon build-up can cause a variety of problems with your vehicle's performance, including decreased fuel economy, hesitation or stalling, and rough idle.
10. Check the condition of hoses, pipes and wiring harnesses.
Hoses, pipes and wiring harnesses should be checked for leaks, cracks or damage during every major service. These components are vital to your vehicle's operation, and any problems should be repaired as soon as possible to avoid further damage.
