1. Gather Tools and Supplies

Before starting, ensure you have the necessary tools and parts. You will need:

  • New spark plugs
  • Spark plug socket
  • Wrenches
  • Replacement air filter
  • Oil and oil filter (if changing oil)

The spark plugs play a crucial role in engine performance. Here’s how to change them:

  1. Locate the spark plug wires and carefully remove them.
  2. Using the spark plug socket, unscrew the old spark plugs.
  3. Inspect the old plugs for wear.
  4. Apply a small amount of anti-seize compound to the threads of the new plugs.
  5. Screw in the new spark plugs and reconnect the wires.

3. Inspecting and Replacing Filters

Clean air filters are essential for optimal air intake. To replace the air filter, follow these steps:

  1. Locate the air filter box.
  2. Open the box and remove the old air filter.
  3. Insert the new air filter, ensuring it fits snugly.
  4. Close the air filter box securely.

4. Checking Fluid Levels

Regularly check and top up essential fluids, including:

  • Transmission Fluid: Ensure optimal levels for a smooth drive.

5. Cleaning the Throttle Body

The throttle body regulates air intake into the engine, making its maintenance crucial. Here’s how to clean it:

  1. Locate the throttle body.
  2. Use a throttle body cleaner to spray the inside of the throttle body.
  3. Gently scrub any carbon deposits with a soft cloth.
