Solution

1. Preparation

Gather tools: socket set, coolant pressure tester, OBD-II scanner, and multimeter.
Ensure the engine is cool before beginning work to avoid burns.
Disconnect the battery to ensure safety during electrical inspections.

2. Check and Refill Coolant

Locate the coolant reservoir and remove the cap.
Inspect the coolant level; if low, refill with a 50/50 mixture of coolant and distilled water.
Inspect for any signs of leaks around hoses and connections.

3. Inspect and Replace Thermostat (if defective)

Drain the coolant from the radiator using a drain pan.
Remove the thermostat housing by disconnecting bolts (torque specs: 10-15 ft-lbs).
Replace the thermostat if it is stuck closed (check opening temperature).
Reinstall the housing, ensuring a new gasket is used.

4. Check Radiator Fan Operation

Reconnect the battery and start the engine.
Turn on the air conditioning to force the radiator fan to engage.
Use a multimeter to check for voltage at the fan connector.
If the fan does not operate, replace the fan motor as necessary.

5. Inspect Radiator and Hoses

Visually inspect the radiator for any physical damage or blockages.
Check hoses for cracks, bulges, or leaks and replace as necessary.
Clean any debris from the radiator fins to improve airflow.

6. Test Drive and Monitor

Refill any lost coolant and ensure all components are secure.
Test drive the vehicle, monitoring the temperature gauge closely.
If overheating persists, further diagnostics may be needed for the water pump or internal engine issues.
