Solution

1. Preparation

Gather tools and parts.
Ensure the engine is cool and disconnect the battery.
Tools required: socket set, screwdrivers, coolant pressure tester, OBD-II scanner.

2. Check and Replace Coolant

Sub-steps:
1. Remove the coolant reservoir cap and inspect the coolant level.
2. If low, top off with the correct type of coolant (Ford Gold or equivalent).
3. If coolant is contaminated or old, drain the system and replace it entirely.
4. Refill the system with fresh coolant and bleed air from the system.

3. Inspect and Replace Thermostat

Sub-steps:
1. Locate the thermostat housing (usually where the upper radiator hose connects).
2. Remove the bolts holding the housing with a socket set.
3. Take out the old thermostat and inspect the gasket.
4. Install the new thermostat with a new gasket.
5. Reattach the housing and torque to manufacturer specifications (typically around 15-20 ft-lbs).

4. Inspect and Repair Cooling System Components

Sub-steps:
1. Check all hoses for cracks or leaks and replace any that are damaged.
2. Inspect the water pump for leaks and proper operation; replace if necessary.
3. Ensure the radiator is free of debris and clear any blockages.
4. Test the radiator fan’s operation by turning on the engine and checking for engagement; replace the fan motor if it does not work.

5. Final Checks

Sub-steps:
1. Reconnect the battery.
2. Start the engine and monitor the temperature gauge.
3. Check for leaks around the thermostat housing and hoses.
4. Test drive the vehicle to ensure the issue is resolved.
