Solution

1. Preparation

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

2. Check and Refill Coolant

Tools Required: Coolant funnel, new coolant
Inspect the coolant reservoir and radiator, and refill with the appropriate coolant mixture as per manufacturer's specifications.
Check for any visible leaks after refilling.

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 mating surface.
Install the new thermostat, ensuring it is oriented correctly.
Reattach the thermostat housing and torque the bolts to the manufacturer’s specifications.

4. Water Pump Inspection/Replacement

Tools Required: Socket set, screwdriver, gasket scraper
If the water pump is leaking or not functioning, drain the coolant and remove the serpentine belt.
Unbolt the water pump from the engine block and remove it.
Clean the mating surface and install a new water pump with a new gasket.
Reattach the serpentine belt and refill coolant.

5. Cooling Fan Check

Tools Required: Multimeter
With the engine running, check the electrical connections to the cooling fan.
Use a multimeter to test for power at the fan connector.
If the fan does not operate, replace the cooling fan assembly.
