Solution

1. Preparation

Gather necessary tools and safety equipment.
Ensure the engine is cool before starting work to avoid burns.

2. Check Coolant Level

Sub-steps:
- Open the hood and locate the coolant reservoir.
- Inspect the coolant level; it should be between the minimum and maximum marks.
- If low, top off with a 50/50 mixture of coolant and distilled water.

3. Inspect and Replace Thermostat

Tools Required: Socket set, torque wrench, coolant catch pan.
Sub-steps:
- Drain the coolant into a catch pan by removing the drain plug from the radiator.
- Disconnect the negative battery cable to prevent electrical shorts.
- Remove the thermostat housing bolts and take off the housing.
- Remove the old thermostat and clean the mating surfaces.
- Install the new thermostat ensuring it is seated correctly.
- Reattach the thermostat housing and torque the bolts to the manufacturer's specifications.

4. Check and Repair Cooling System Leaks

Sub-steps:
- Visually inspect all hoses, clamps, and the radiator for cracks or damage.
- Replace any damaged hoses or components.
- If leaks are found, repair or replace the necessary parts.

5. Test Radiator Fans

Sub-steps:
- Start the engine and let it idle to reach operating temperature.
- Observe if the radiator fans activate; they should turn on when the engine reaches a certain temperature.
- If not operational, test the fan motor and relay for continuity and replace as needed.
