Solution

1. Preparation

Gather necessary tools and parts. Ensure the vehicle is parked on a level surface and the engine is cool.
Tools required: socket set, coolant pressure tester, OBD-II scanner, multimeter, and safety gloves.
Safety warnings: Disconnect the battery before working on electrical systems and allow the engine to cool before opening the radiator.

2. Coolant Level Check

Open the coolant reservoir cap carefully.
If the coolant is low, add the appropriate type of coolant mixture as specified in the owner’s manual.

3. Inspect for Leaks

Visually inspect hoses and connections for any signs of coolant leaks.
If leaks are detected, replace the affected hoses or components as necessary.

4. Thermostat Replacement

Drain the coolant from the radiator and remove the thermostat housing.
Replace the old thermostat with a new one, ensuring the gasket is properly seated.
Refill the cooling system with the appropriate coolant mixture.

5. Radiator Cleaning

Remove any debris or obstructions from the radiator fins.
If the radiator is clogged, consider using a radiator flush or replacing it.

6. Cooling Fan Check

Test the cooling fans by connecting them directly to a power source to ensure they operate.
If the fans do not work, replace the fan motor or check the relay and fuse.
