Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and allow the engine to cool down completely.
Disconnect the battery to prevent electrical short circuits.

2. Inspect and Replace Coolant

Tools Required: Coolant, funnel, gloves
Sub-steps:
1. Remove the coolant reservoir cap carefully to avoid injury from hot coolant.
2. Check the coolant level; if it's low, top it off with the appropriate coolant type specified in the owner’s manual.
3. If coolant is contaminated or old, drain the system completely and replace it with new coolant.

3. Inspect and Replace Hoses

Tools Required: Pliers, hose clamp removal tool
Sub-steps:
1. Visually inspect all coolant hoses for cracks, bulges, or leaks.
2. Gently squeeze hoses to check for stiffness, which indicates wear.
3. If damaged hoses are found, use a hose clamp removal tool to remove the old hoses and install new ones, ensuring a secure fit.

4. Check and Clean Radiator

Tools Required: Hose, bucket, wire brush
Sub-steps:
1. Inspect the front of the radiator for dirt or debris; clean it using a wire brush if necessary.
2. Use a hose to flush out any blockages by spraying from the back of the radiator.
3. Ensure airflow is not obstructed by checking for bent fins.

5. Test Cooling Fan Operation

Tools Required: Multimeter
Sub-steps:
1. Reconnect the battery and start the engine.
2. Use a multimeter to check the voltage at the cooling fan connector; it should show proper voltage when the engine reaches operating temperature.
3. If the fan does not engage, check the fan relay and replace if necessary.

6. Final Checks

Tools Required: OBD-II scanner
Sub-steps:
1. Scan for any DTCs that may indicate further issues.
2. Clear any codes and monitor the vehicle during a test drive to ensure proper operation and cooling.
