Ignition System:
1. Spark Plug Replacement: Replacing worn-out spark plugs with new ones ensures efficient ignition and optimal engine performance.
2. Spark Plug Wire Inspection/Replacement: Check for any cracked or damaged spark plug wires and replace them if necessary. Proper electrical connection is crucial for a consistent spark.
Engine Air Filter:
Replace the engine air filter if it appears dirty or clogged. A clean filter allows sufficient airflow into the engine for better combustion.
Fuel Filter:
A clogged fuel filter can restrict fuel flow to the engine, leading to performance issues. Replace the fuel filter as per the recommended maintenance schedule.
Throttle Body Cleaning:
Cleaning the throttle body helps remove carbon buildup and allows for smoother airflow, resulting in better engine responsiveness and fuel efficiency.
PCV (Positive Crankcase Ventilation) Valve:
Replace the PCV valve if it's malfunctioning or clogged. A defective PCV valve can affect engine performance and efficiency.
Fluid Check and Top-up:
- Engine Oil: Check the engine oil level and top up as needed with the recommended oil type.
- Transmission Fluid: Check the automatic transmission fluid level and add more if required.
- Brake Fluid: Ensure that the brake fluid is at the appropriate level in the master cylinder.
- Coolant/Antifreeze: Verify the coolant level and replenish if necessary.
Check Tire Conditions:
Inspect the tire treads for adequate depth and uneven wear. Ensure proper tire pressure as per the recommended PSI.
Battery Inspection and Cleaning:
Check the battery terminals for any signs of corrosion. Clean the terminals if necessary to maintain good electrical connections.
Serpentine Belt Inspection:
Look for cracks, fraying, or excessive wear on the serpentine belt. Replace it if found damaged.
Computer Diagnostic Check:
If the vehicle has a "Check Engine" light on, it's recommended to have a computer diagnostic scan performed to identify any potential issues.
Some additional services that may be recommended for preventive maintenance, but are not necessarily part of a basic tune-up:
- Fuel injector cleaning
- Transmission service
- Coolant flush
- Brake system check
- Axle lubricant change
It's always advisable to consult with a reliable auto repair shop or refer to the owner's manual for the specific maintenance tasks recommended for your vehicle model and mileage.
