Solution

1. Preparation

Tools Required: Socket set, Screwdrivers, Coolant leak detector, OBD-II scanner.
Safety Warnings: Allow engine to cool completely before opening the radiator cap or working on the cooling system.

2. Add Coolant

Open the hood and locate the coolant reservoir.
If low, add the appropriate type of coolant (refer to owner's manual for specifications) until reaching the full mark.

3. Replace Thermostat (if faulty)

Tools Required: Socket set, Gasket scraper, Torque wrench.
Remove the thermostat housing bolts.
Take out the old thermostat and replace it with a new one, ensuring the correct orientation.
Reattach the housing and torque bolts to the manufacturer's specifications.

4. Clean or Replace Radiator

Inspect the radiator for clogs or debris.
If clogged, clean it with a radiator cleaner or replace it if necessary.
Ensure that all connections and hoses are secure.

5. Check and Repair Water Pump

Inspect the water pump for leaks or unusual noise.
If malfunctioning, remove the old water pump and install a new one, following proper torque specifications for mounting bolts.

6. Verify Fan Operation

Start the engine and let it reach operating temperature.
Ensure that the cooling fans engage when the engine reaches the specified temperature.
Replace the fan motor if it does not operate.
