Solution

1. Preparation

Gather necessary tools and parts.
Ensure the engine is cool and disconnect the battery to avoid electrical hazards.

2. Coolant Replacement

Sub-steps:
1. Remove the radiator cap to release pressure.
2. Place a drain pan under the radiator and open the drain valve to empty the coolant.
3. Close the drain valve and refill with new coolant (mix as per manufacturer specifications).

3. Thermostat Replacement

Tools Required: Socket set, torque wrench
Sub-steps:
1. Locate the thermostat housing and remove the bolts using a socket set.
2. Carefully remove the thermostat and inspect the gasket for wear.
3. Install the new thermostat with a new gasket, ensuring it is seated correctly.
4. Torque the housing bolts to the manufacturer’s specifications.

4. Radiator Fan Check

Sub-steps:
1. Start the engine and allow it to reach operating temperature.
2. Observe the radiator fan operation; it should engage as the engine heats up.
3. If the fan does not engage, check the fuse and relay, and replace if necessary.

5. Leak Repair

Sub-steps:
1. Inspect all hoses and connections for leaks.
2. Replace any damaged hoses or clamps.
3. Use a coolant stop leak product if minor leaks are present, or replace the affected components as needed.
