Solution

1. Preparation

Gather tools and materials.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to prevent electrical shorts.

2. Check and Replace Engine Oil

Remove the oil dipstick and check the oil level.
If low, drain the old oil using a wrench to remove the oil pan bolt.
Replace with manufacturer-recommended oil using a funnel.
Replace the oil filter if necessary.
Tighten the oil pan bolt to manufacturer specifications (typically around 20 lb-ft).

3. Check and Replace Transmission Fluid

Locate the transmission dipstick and remove it.
Check the fluid level; if low, add the correct type of transmission fluid.
If the fluid smells burnt, consider a complete fluid change:
- Drain the transmission fluid by removing the pan bolts.
- Replace the transmission filter if applicable.
- Reinstall the pan and tighten bolts to specifications.
- Refill with new transmission fluid through the dipstick tube.

4. Inspect and Replace Coolant

Check the coolant reservoir for proper fluid level.
If low, inspect hoses for leaks and the radiator for integrity.
If necessary, drain old coolant by opening the radiator drain valve.
Flush the system and refill with a 50/50 mix of coolant and distilled water.

5. Brake Inspection

Remove the wheel to access the brake assembly.
Inspect brake pads and rotors for excessive wear.
Replace any worn components with high-quality parts.
Reassemble and ensure proper torque specifications are followed.
