Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.

2. Inspect and Replace Engine Oil

Sub-steps:
1. Remove the oil drain plug using a socket wrench and drain the oil into a container.
2. Replace the oil filter using an oil filter wrench.
3. Install a new oil filter and tighten it by hand.
4. Reinstall the drain plug and torque it to manufacturer's specifications (typically 20-25 ft-lbs).
5. Refill the engine with the appropriate type and amount of oil (check owner's manual).

3. Check and Replace Coolant

Sub-steps:
1. Locate the radiator cap and carefully remove it (ensure engine is cool).
2. Inspect the coolant level in the reservoir; if low, add the proper coolant mix (50/50 coolant/water).
3. Look for leaks in hoses or the radiator and replace any damaged components.

4. Inspect and Replace Brake Components

Sub-steps:
1. Lift the vehicle using a jack and secure it with jack stands.
2. Remove the wheel to access the brake assembly.
3. Inspect brake pads and rotors for wear; replace if necessary.
4. Reinstall the wheel and lower the vehicle.

5. Check and Replace Transmission Fluid

Sub-steps:
1. Locate the transmission dipstick and remove it.
2. Check the fluid level; if low, add the correct type of transmission fluid.
3. If the fluid is burnt, consider a complete transmission fluid change.
