Solution

1. Preparation

Gather tools: OBD-II scanner, coolant pressure tester, socket set, torque wrench, and multimeter.
Ensure the engine is cool before beginning work to prevent burns.

2. Inspect and Replace Coolant

Step 1: Remove the coolant reservoir cap and check the coolant level. If low, top up with the recommended coolant type.
Step 2: If the coolant is dirty or contaminated, drain the cooling system using a coolant drain pan.
Step 3: Flush the system with a coolant flush solution, then refill with a 50/50 mixture of antifreeze and distilled water.

3. Thermostat Inspection and Replacement

Step 1: Locate the thermostat housing and disconnect the upper radiator hose.
Step 2: Remove the thermostat housing bolts using a socket set and take out the thermostat.
Step 3: Inspect the thermostat for functionality; replace if stuck closed or open.
Step 4: Reinstall the thermostat with a new gasket and torque the bolts to manufacturer specifications.

4. Water Pump Inspection and Replacement

Step 1: Check for leaks around the water pump and listen for unusual noises.
Step 2: If defective, remove the drive belt and unbolt the water pump from the engine block.
Step 3: Install a new water pump, ensuring proper gasket placement, and torque to manufacturer specifications.

5. Radiator Fan Testing and Replacement

Step 1: Start the engine and allow it to reach operating temperature, monitoring the radiator fan operation.
Step 2: If the fan does not engage, test it using a multimeter for continuity.
Step 3: Replace the radiator fan if it is not functioning correctly.
