Solution

1. Preparation

Gather necessary tools and parts.
Ensure the engine is cool before starting work to avoid burns.
Disconnect the battery to prevent electrical shorts.

2. Inspect and Replace Coolant

Drain the coolant from the radiator using a drain pan.
Check the coolant condition; if contaminated or old, replace it.
Refill with manufacturer-recommended coolant (typically a 50/50 mix of antifreeze and distilled water).
Tighten the radiator cap securely.

3. Thermostat Replacement

Remove the lower engine cover if applicable.
Disconnect the thermostat housing from the engine block (usually requires a socket set).
Remove the old thermostat and gasket.
Install the new thermostat and gasket, ensuring it is seated properly.
Reattach the thermostat housing and torque bolts to manufacturer specifications (typically around 15-20 ft-lbs).

4. Water Pump Inspection/Replacement

If the water pump is leaking or not functioning, remove the serpentine belt.
Disconnect hoses from the water pump and remove the mounting bolts.
Install the new water pump with a new gasket, ensuring proper alignment and torque specifications (generally around 18-22 ft-lbs).
Reconnect hoses and the serpentine belt.

5. Radiator Fan Test

Reconnect the battery and start the engine.
Allow the engine to reach operating temperature and check if the radiator fan engages.
If not, check fuses and wiring to the fan; replace the fan if necessary.
