Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the engine is cool before starting the repair.
Disconnect the negative battery terminal for safety.

2. Coolant Level and Leaks

Tools Required: Coolant catch pan, funnel
Check and top off the coolant level in the radiator and reservoir.
Inspect for any visible leaks around hoses, the radiator, and the water pump.
If leaks are found, replace the affected hoses or components as needed.

3. Thermostat Replacement

Tools Required: Socket set, torque wrench, gasket scraper
Remove the thermostat housing by unscrewing the bolts.
Take out the old thermostat and clean the surface where it was mounted.
Install a new thermostat (ensure it's rated for the correct temperature).
Reattach the thermostat housing and torque to manufacturer's specifications.

4. Electric Cooling Fan Inspection/Replacement

Tools Required: Multimeter, socket set
With the engine running, check if the cooling fans are functioning by observing their operation.
If fans do not activate, test the fan motor with a multimeter for continuity.
If faulty, remove the fan assembly and replace it with a new fan.

5. Water Pump Inspection/Replacement

Tools Required: Socket set, coolant catch pan, gasket scraper
Inspect for leaks around the water pump; if leaking, it will need to be replaced.
Drain the coolant using a catch pan.
Remove the water pump by unscrewing the bolts and disconnecting the hoses.
Install the new water pump, ensuring a new gasket is used, and torque to the manufacturer's specifications.
