Solution

1. Preparation

Gather tools and materials. Ensure the engine is cool before starting.
Tools Required:
- OBD-II scanner
- Socket set
- Torque wrench
- Coolant pressure tester
- Screwdrivers
- Pliers

2. Address Coolant Issues

Check and top off coolant:
- Open the coolant reservoir cap carefully.
- Add coolant (compatible type) to the proper level.
Flush the cooling system if needed:
- Connect a coolant flush kit to the radiator.
- Run the engine and follow the flushing directions until the fluid runs clear.

3. Repair or Replace Components

Inspect and replace the thermostat:
- Drain coolant from the system.
- Remove the thermostat housing by loosening bolts (use torque specs for reassembly).
- Replace the thermostat and gasket, then reassemble.
Examine and replace the water pump if faulty:
- Disconnect the drive belt (if applicable).
- Remove the water pump by loosening mounting bolts.
- Clean the mating surface and install the new pump with a new gasket.

4. Verify Fan Operation

Test cooling fan functionality:
- Start the engine and allow it to reach operating temperature.
- Ensure the cooling fans activate; if not, check the wiring and fan relay.

5. Final Assembly and Coolant Fill

Replace any removed components and ensure all connections are secure.
Fill the cooling system with the appropriate type of coolant.
Start the engine and allow it to run, checking for leaks and proper circulation.
