Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and engine is cool.
Disconnect the battery to prevent electrical issues.

2. Coolant Level Check

Remove the coolant reservoir cap.
If the coolant is low, top it off with manufacturer-recommended coolant.
Inspect the system for leaks before proceeding.

3. Replace Faulty Components

A. Thermostat Replacement

Locate the thermostat housing and remove the necessary components to access it.
Detach the thermostat from the housing.
Replace with a new thermostat, ensuring proper orientation.
Reassemble the housing and tighten bolts to manufacturer specifications.

B. Radiator Fan Inspection

Ensure the fan is electrically connected and check for any damaged wiring.
If the fan does not operate, replace it with a new unit.

4. Pressure Test the Cooling System

Use a cooling system pressure tester to check for leaks.
If leaks are found, replace affected hoses or the radiator as needed.

5. Refill and Bleed the Cooling System

Refill the cooling system with the appropriate coolant mixture.
Run the engine with the coolant reservoir cap off until the thermostat opens, allowing air to escape.
Replace the cap once the coolant stabilizes.
