Solution

1. Preparation

Ensure the vehicle is parked on a level surface and the engine is off.
Allow the engine to cool completely before proceeding to avoid burns.
Gather necessary tools and parts.

2. Inspect and Replace Coolant

Sub-steps:
1. Remove the coolant reservoir cap carefully to avoid pressure release.
2. Check the coolant level; if low, add the appropriate coolant mixture (commonly a 50/50 mix of coolant and distilled water).
3. If the coolant is dirty or has not been changed in a while, drain the old coolant from the radiator and replace it with fresh coolant.
Tools Required: Coolant funnel, drain pan, rags.

3. Check and Replace Cooling Fan

Sub-steps:
1. Disconnect the negative battery terminal to ensure safety.
2. Remove any covers obstructing access to the cooling fan.
3. Test the fan by connecting it directly to a power source; if it does not operate, replace the fan.
4. Install the new fan and reconnect all wiring and connectors.
Tools Required: Socket set, wire connectors, multimeter.

4. Inspect Radiator and Hoses

Sub-steps:
1. Visually inspect the radiator for any physical damage, debris, or blockages.
2. Check all hoses for cracks or leaks; replace any damaged hoses.
3. Clean any debris from the front of the radiator that may obstruct airflow.
Tools Required: Hose clamp pliers, cleaning brush.
