Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to avoid any electrical issues.

2. Identify and Repair Oil Leaks

Tools Required: Socket set, wrench set, oil catch pan.
Sub-steps:
1. Remove any engine covers obstructing access to the engine components.
2. Use a flashlight to inspect for oil leaks around the oil filter, oil pan, and gaskets.
3. Tighten any loose bolts or fittings found during the inspection.
4. If any damaged components (like gaskets) are found, replace them:
  - Remove the affected component.
  - Clean the mating surfaces of old gasket material.
  - Apply a new gasket or sealant as required and reinstall the component.

3. Change Oil and Filter

Tools Required: Oil filter wrench, oil catch pan, funnel.
Sub-steps:
1. Place the oil catch pan under the oil pan.
2. Remove the oil drain plug and allow the oil to fully drain.
3. Replace the oil filter using the oil filter wrench.
4. Reinstall the drain plug and tighten to manufacturer specifications.
5. Add new oil through the oil filler cap, using the type and amount specified in the owner’s manual.

4. Inspect and Repair Cooling System

Tools Required: Coolant pressure tester, multimeter (if electrical issues suspected).
Sub-steps:
1. Check the coolant level in the reservoir; add coolant if low.
2. Inspect hoses for cracks or leaks.
3. Test the radiator cap for pressure retention using a coolant pressure tester.
4. If the cooling fan is not operating, test the fan motor and relay with a multimeter and replace if necessary.
