1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to ensure safety while working on electrical components.

2. Inspect and Replace Engine Oil

- Remove the engine oil dipstick and check the oil level and condition. If low or burnt, proceed to replace.
- Drain the old oil using a wrench to remove the oil drain plug. Allow it to fully drain into a suitable container.
- Replace the oil filter using an oil filter wrench to remove the old filter.
- Install the new oil filter and ensure it is properly sealed.
- Reinstall the oil drain plug and torque to manufacturer specifications (typically around 30-35 lb-ft).
- Refill the engine with the recommended oil type (5W-20 or as specified in the owner’s manual).

3. Inspect and Replace Belts and Hoses

Sub-steps:
- Visually inspect all accessible belts and hoses for signs of wear, fraying, or damage.
- If damaged, loosen the tensioner and remove the old belt. Replace with a new OEM or high-quality replacement belt.
- For hoses, clamp off the flow, remove the damaged hose, and install a new hose ensuring proper fit and secure clamps.

4. Check and Repair Exhaust System

Sub-steps:
- Inspect the entire exhaust system for holes, cracks, or loose connections.
- Tighten any loose bolts or connections.
- Replace any damaged sections of the exhaust using an exhaust pipe cutter and clamps for secure attachment.

5. Verify Transmission Fluid

Sub-steps:
- Check the transmission fluid level using the dipstick; if low or burnt, prepare to replace.
- Drain the old transmission fluid and replace the filter if applicable.
- Refill with the manufacturer-recommended transmission fluid type.
