1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery to ensure safety during repairs.

2. Inspect and Replace Accessory Drive Belt

Inspect the Belt:
- Visually check the accessory drive belt for cracks, fraying, or glazing.
Replace if Necessary:
- Loosen the tensioner using a wrench.
- Remove the old belt from the pulleys.
- Route the new belt according to the belt routing diagram.
- Tighten the tensioner back in place.

3. Check and Top Off Power Steering Fluid

Inspect Fluid Level:
- Locate the power steering reservoir and check the fluid level.
Top Off Fluid:
- If low, add the manufacturer-recommended power steering fluid until it reaches the correct level.

4. Inspect and Replace Transmission Fluid

Check Fluid Level:
- With the engine running, use the dipstick to check the transmission fluid level.
Replace Fluid if Necessary:
- If low or dirty, drain the old fluid using a transmission pump or drain plug.
- Replace with the recommended transmission fluid type for the Honda CR-V.
- Recheck fluid level after filling.
