Solution

1. Preparation

Ensure the engine is cool before starting work.
Disconnect the battery to prevent any electrical shorts.
Gather tools and parts required for the repair.

2. Inspect and Repair Leaks

Tools Required: Socket set, coolant pressure tester, oil catch pan.
Check for leaks in the engine coolant system:
1. Pressure test the cooling system using a coolant pressure tester.
2. If a leak is found, replace the leaking hose or radiator.
3. Refill the cooling system with the appropriate coolant type (Ford specification).

3. Change Oil and Filter

Tools Required: Oil filter wrench, socket set, oil catch pan.
If oil appears burnt or contaminated:
1. Drain the old engine oil into the oil catch pan.
2. Replace the oil filter using an oil filter wrench.
3. Refill the engine with fresh oil (5W-20 or as specified by the manufacturer).

4. Inspect and Replace Serpentine Belt (if needed)

Tools Required: Socket set, belt tensioner tool.
If the serpentine belt shows signs of wear:
1. Loosen the tension on the belt using the tensioner tool.
2. Remove the old belt and replace it with a new one, ensuring it follows the correct routing.

5. Brake System Inspection

Tools Required: Jack and jack stands, lug wrench, brake cleaner.
If brake components are suspect:
1. Raise the vehicle and remove the wheels.
2. Inspect brake pads and rotors for excessive wear or overheating.
3. Replace any worn components as necessary to restore proper braking function.
