- Replace the drain plug and install a new oil filter.
- Refill the engine with the appropriate amount of new engine oil (refer to your owner's manual for the recommended type and quantity).
4. Replace Air Filter:
- Open the air filter housing (usually located on top of the engine).
- Remove the old air filter and insert a new one.
- Ensure the filter is properly seated before replacing the housing cover.
5. Replace Cabin Air Filter:

- Remove the old filter and insert a new one.
6. Change Fuel Filter:
- The fuel filter is usually located near the fuel tank.
- Disconnect the fuel lines and remove the old filter.
- Install a new fuel filter and reconnect the fuel lines.
7. Check and Change Spark Plugs:
- Use the spark plug wrench to loosen and remove the old spark plugs.
- Inspect the plugs for signs of wear or damage.
- If necessary, gap the new plugs to the specified measurement.
- Screw in the new spark plugs and tighten them securely.
- Reattach the spark plug wires.
8. Replace Serpentine/Drive Belt:
- If the belt shows signs of wear or cracking, you'll need to replace it.
- Locate the tensioner pulley and loosen it to release tension on the belt.
- Remove the old belt and carefully install a new one.
- Re-tension the belt according to the manufacturer's specifications.
9. Change Brake Fluid:

- Replace the drain plug and fill the transmission with new fluid through the fill plug.
11. Replenish Coolant/Antifreeze:
- Check the coolant level in the reservoir. If low, mix the proper ratio of coolant and water (check the manual) and add it.
- Ensure the reservoir is filled to the recommended level.
12. Reconnect the Battery:
- Reconnect the negative terminal of the battery.
13. Test Drive:
- Start the engine and let it run for a few minutes.
- Take the vehicle for a short test drive to ensure everything is working properly.
14. Final Checks:
- After driving, double-check fluid levels, look for any leaks, and listen for any unusual noises or vibrations.
