Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to prevent electrical issues while working.

2. Inspect and Replace Serpentine Belt

Sub-steps:
1. Remove any covers obstructing access to the serpentine belt.
2. Loosen the tensioner pulley using a ratchet and socket to relieve tension on the belt.
3. Carefully remove the old serpentine belt from the pulleys.
4. Inspect pulleys for wear or damage.
5. Install the new serpentine belt following the belt routing diagram.
6. Reapply tension with the tensioner pulley and ensure the belt is properly seated.

3. Check and Replace Transmission Fluid

Sub-steps:
1. Locate the transmission dipstick or fill plug.
2. Remove the dipstick and check the fluid level; top off with manufacturer-recommended fluid if low.
3. If fluid is dark or smells burnt, drain and replace it by removing the transmission pan.
4. Clean the pan and replace the filter if applicable.
5. Reinstall the pan with new gasket and torque to manufacturer specifications.

4. Inspect and Replace Differential Fluid (if applicable)

Sub-steps:
1. Locate the differential fill and drain plugs.
2. Remove the drain plug and allow old fluid to drain completely.
3. Inspect fluid for metal shavings or contaminants.
4. Reinstall the drain plug and fill with new differential fluid until it reaches the fill plug level.
