Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, fluid catch pan, rags, flashlight
Ensure the vehicle is parked on a flat surface and the engine is cool.
Disconnect the battery to prevent electrical shorts during inspection.

2. Check and Replace Engine Oil

Sub-steps:
1. Remove the oil drain plug using a socket wrench and allow the old oil to drain into the catch pan.
2. Replace the oil filter using an oil filter wrench.
3. Install the drain plug and torque to manufacturer specifications (typically around 25 lb-ft).
4. Fill the engine with new oil (refer to the owner’s manual for the correct oil type and capacity).
5. Start the engine and let it run for a few minutes, then check for leaks.

3. Check and Replace Transmission Fluid

Sub-steps:
1. Locate the transmission fluid dipstick and remove it.
2. If the fluid is low or burnt, drain the transmission fluid using the appropriate drain plug.
3. Replace the transmission filter if applicable.
4. Refill the transmission with new fluid (consult the owner’s manual for the correct fluid type).
5. Check the fluid level again after running the engine.

4. Address Fluid Leaks

Sub-steps:
1. Clean the area around any suspected leaks with rags.
2. Identify the source of the leak by running the engine and observing for drips.
3. Replace any faulty seals, gaskets, or hoses as necessary.
4. Recheck all connections for tightness.

5. Inspect and Replace Belts and Hoses

Sub-steps:
1. Visually inspect all belts for cracks and fraying.
2. Check hoses for bulges, cracks, or leaks.
3. Replace any damaged belts or hoses with new parts.
4. Ensure all components are secured and properly fitted.
