Ensure the vehicle is parked on a level surface and secure it with wheel chocks.
Disconnect the battery to avoid electrical issues during repairs.

Tools Required:

OBD-II scanner
Torque wrench
Socket set

2. Inspect and Replace Power Steering Fluid

Remove the power steering reservoir cap and check the fluid level.
If low, add the recommended fluid type (check owner's manual).
If the fluid looks dirty or contaminated, proceed to replace it:
- Disconnect the return line from the power steering pump.
- Use a fluid catch pan to drain old fluid.
- Reconnect the return line and refill with new fluid.

3. Check and Replace Drive Belts

Inspect the drive belts for any signs of wear or damage.
If the belt is frayed or cracked, proceed as follows:
- Use a socket set to loosen the tensioner and remove the old belt.
- Install the new belt according to the routing diagram.
- Adjust the tensioner to the specified torque value (refer to service manual).

4. Inspect and Repair Transmission (if necessary)

Check the transmission fluid level using the dipstick.
If low, add the recommended transmission fluid type.
If the fluid is burnt or contaminated, perform a transmission fluid change:
- Remove the transmission pan and replace the filter.
- Reinstall the pan with new gasket and torque to specifications.
- Refill with new transmission fluid.
