Solution

1. Preparation

Ensure the vehicle is parked on a level surface and the engine is off.
Wear safety gloves and goggles.
Tools Required: Socket set, screwdrivers, brake cleaner, oil catch pan.

2. Address Fluid Leaks

Locate the source of the leak.
- For oil leaks: Replace worn gaskets or seals as necessary.
- For coolant leaks: Replace hoses or the radiator if damaged.

3. Cooling System Check

Inspect the radiator and hoses for blockages or damage.
Replace any damaged hoses and ensure the coolant is at the proper level.
Flush the cooling system if necessary and refill with the recommended coolant.

4. Brake Inspection and Replacement

Remove the wheel to access the brake components.
Inspect brake pads for wear; replace if less than 1/8 inch thick.
Check the rotors for scoring or warping; replace if necessary.
Clean brake components with brake cleaner.

5. Electrical System Inspection

Inspect wiring harnesses and connectors for damage or corrosion.
Replace any frayed or burnt wiring.
Verify all connections are secure.

6. Engine Oil Check

Remove the dipstick and wipe it clean; reinsert and check oil level.
If low, add the appropriate engine oil as per manufacturer specifications.
