Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, jack and jack stands, serpentine belt tool, multimeter.
Disconnect the battery before starting work on electrical components.

2. Inspect and Replace Serpentine Belt

Visual Inspection: Remove the engine cover if applicable. Inspect the serpentine belt for any signs of wear or damage.
Remove the Old Belt: Use a serpentine belt tool to relieve tension and remove the belt from the pulleys.
Install New Belt: Route the new serpentine belt according to the belt routing diagram located on the engine bay. Ensure it is seated properly on all pulleys.

3. Check and Replace Fluids

Transmission Fluid Check: Remove the transmission dipstick, wipe clean, and reinsert to check fluid level. If low, add the recommended transmission fluid (Honda ATF DW-1).
Power Steering Fluid: Check the reservoir level. If low, add Honda power steering fluid until the proper level is reached.
Differential Fluid: If applicable, check the differential fluid level and replace if it appears contaminated or low.

4. Inspect and Replace Wheel Bearings

Raise Vehicle: Use a jack to lift the front or rear of the vehicle, securing it with jack stands.
Check Wheel Bearings: Spin the wheel by hand and listen for noise. If noise is present or there is excessive play, remove the wheel and inspect the bearing.
Replace Wheel Bearing: If necessary, remove the hub assembly and press out the old bearing. Install the new bearing and reassemble.
