Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the engine is cool before beginning work.
Disconnect the battery to avoid electrical issues.

2. Coolant Level Check and Refill

Open the coolant reservoir cap carefully.
Check the coolant level; if low, top off with the manufacturer-recommended coolant.
Inspect for any signs of contamination (like oil in the coolant).

3. Thermostat Replacement

Tools Required: Socket set, torque wrench, coolant catch pan
Remove the thermostat housing bolts using a socket wrench.
Carefully lift the thermostat out of its housing.
Replace with a new thermostat and ensure it’s oriented correctly.
Reattach the housing, torque the bolts to the manufacturer’s specifications.

4. Radiator Fan Inspection/Replacement

Tools Required: Multimeter, socket set
Test the fan motor by connecting it directly to a power source to see if it operates.
If the fan does not operate, replace with a new fan assembly.
Ensure all electrical connections are secure and free of corrosion.

5. Water Pump Inspection/Replacement

Tools Required: Socket set, coolant catch pan
Check for any leaks or noise from the water pump.
If faulty, drain the coolant, remove the water pump, and replace it with a new one, ensuring proper alignment and torque specifications.
