Solution

1. Preparation

Ensure the vehicle is parked on a level surface and the engine is cool.
Gather tools and safety gear, including gloves and safety glasses.

2. Coolant Level Adjustment

Tools Required: Coolant funnel, distilled water or appropriate coolant
If coolant levels are low, add the correct mixture of coolant and distilled water to the reservoir until it reaches the proper level.

3. Thermostat Replacement

Tools Required: Socket set, torque wrench, gasket scraper
Drain coolant from the radiator until it is below the thermostat level.
Disconnect the negative battery terminal.
Remove the thermostat housing bolts and lift the housing off.
Replace the old thermostat with a new one, ensuring proper orientation.
Clean the mating surfaces and install a new gasket.
Reattach the thermostat housing and torque bolts to manufacturer specifications.

4. Radiator and Hose Inspection

Tools Required: Hose clamps, pliers
Inspect all hoses for wear, cracks, or leaks. Replace any damaged hoses.
Check the radiator for signs of corrosion or blockages. If blocked, flush the radiator with a radiator flush solution.

5. Radiator Fan Test

Tools Required: Multimeter
Check the radiator fan's electrical connection and operation. If the fan does not engage when the engine heats up, test the fan motor and replace if necessary.
