Solution

1. Preparation

Gather tools and equipment: OBD-II scanner, socket set, torque wrench, multimeter, fluid containers.
Disconnect the battery to ensure safety while working on electrical components.
Elevate the vehicle if necessary for better access to the engine and drivetrain components.

2. Inspect and Replace Drive Belts

Step 1: Visually inspect the drive belts for damage or wear.
Step 2: If damage is found, use a socket set to loosen the tensioner and remove the old belts.
Step 3: Install new drive belts, ensuring proper routing and tension.
Step 4: Recheck tension and secure the tensioner.

3. Change Engine Oil

Step 1: Remove the oil drain plug and allow old oil to drain into a container.
Step 2: Replace the oil filter using an oil filter wrench.
Step 3: Install the new oil filter and tighten it to the manufacturer’s specifications.
Step 4: Reinstall the drain plug and fill the engine with new oil, checking the level with the dipstick.

4. Check Transmission Fluid

Step 1: Locate the transmission dipstick, if applicable, and remove it.
Step 2: Check the fluid level and condition; top off with the correct type of transmission fluid if low.
Step 3: If fluid is discolored or burnt, consider a transmission fluid flush and replacement.

5. Inspect Power Steering Fluid
