Step-by-Step Guide to Check and Top Up Fluid Levels

1. Checking Engine Oil Level

To check the engine oil level:

  • Park your Altima on a level surface and turn off the engine.
  • Wait a few minutes for the oil to settle.
  • Open the hood and locate the dipstick.

2. Checking Coolant Level

To check the coolant level:

  • Ensure the engine is cool before opening the coolant reservoir.
  • Locate the coolant reservoir, usually a translucent plastic tank.
  • Check the level against the “MIN” and “MAX” markings on the side.
  • If low, add the recommended coolant mixture through the opening.

3. Checking Brake Fluid Level

To check the brake fluid level:

  • Locate the brake fluid reservoir, typically near the back of the engine bay.
  • Check the fluid level against the markings on the reservoir.
  • If the level is low, add the correct type of brake fluid as specified in the owner’s manual.

4. Checking Transmission Fluid Level

To check the transmission fluid level:

  • Start the engine and let it warm up.
  • With the engine running, shift through all gears and return to park.
  • Locate the transmission dipstick (if equipped) and pull it out.
  • Wipe it clean, reinsert, and remove it again to check the level.
  • Add the appropriate type of transmission fluid if necessary.
