Solution

1. Preparation

Gather tools: socket set, screwdriver, coolant catch pan, OBD-II scanner.
Allow the engine to cool down completely before starting any work.
Disconnect the battery for safety.

2. Coolant Level Check and Top-Up

Remove the coolant reservoir cap.
Check the coolant level; if low, top up with a 50/50 mixture of coolant and distilled water.
Replace the cap securely.

3. Inspect and Replace the Thermostat

Remove the thermostat housing bolts using a socket set.
Carefully lift the thermostat out of the housing.
Place the thermostat in boiling water to check for opening; if it does not open, replace it.
Install the new thermostat with a new gasket, tightening the bolts to manufacturer specifications (usually around 15-20 ft-lbs).

4. Inspect and Replace the Water Pump

Remove any components obstructing access to the water pump (e.g., serpentine belt).
Unbolt the water pump from the engine block and remove it.
Install the new water pump with a new gasket, ensuring proper torque on bolts (typically around 18-25 ft-lbs).
Reinstall any components removed earlier.

5. Radiator Inspection and Cleaning

Inspect the radiator for debris, dirt, or damage.
If blocked, use a garden hose to flush out the radiator.
If damaged, replace the radiator with a new unit.

6. Test Radiator Fans

Start the engine and let it reach operating temperature.
Observe the radiator fans: they should engage once the engine reaches a certain temperature.
If they do not operate, check the fan relay and wiring, replacing any faulty components.
