Solution

1. Preparation

Gather tools and parts: OBD-II scanner, socket set, thermometer, coolant, clean rags.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to avoid any electrical issues.

2. Replace Coolant

Drain the old coolant from the radiator by removing the drain plug at the bottom.
Refill the system with a 50/50 mixture of coolant and distilled water.
Bleed the cooling system to remove any air pockets by running the engine with the radiator cap off until coolant circulates and air bubbles escape.

3. Thermostat Replacement

Remove the thermostat housing using a socket set.
Take out the old thermostat and inspect the rubber gasket; replace it if worn.
Install the new thermostat in the correct orientation and reattach the housing, ensuring to torque the bolts to the manufacturer's specifications (typically around 15-25 ft-lbs).

4. Water Pump Inspection/Replacement

If the water pump is found to be faulty, drain the coolant again.
Remove the serpentine belt by using a wrench to relieve tension from the belt tensioner.
Unbolt the water pump from the engine block, then remove it and clean the mounting surface.
Install the new water pump, ensuring that the gasket is properly seated, and torque the bolts as per specifications (usually around 15-20 ft-lbs).

5. Radiator Fan Test/Replacement

With the engine running, verify that the radiator fan is turning on when the engine reaches operating temperature.
If the fan does not operate, check the fan relay and fuses.
Replace the fan motor if necessary, ensuring to disconnect the electrical connector before removal.
