Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the engine is cool before starting to avoid burns.
Disconnect the battery to prevent any electrical issues.

2. Replace Coolant

Tools Required: Coolant flush kit, funnel, and safety goggles.
Drain the coolant from the radiator using the drain plug. Dispose of the old coolant according to local regulations.
Flush the cooling system with clean water to remove any debris.
Refill the system with the manufacturer-recommended coolant mixture (typically a 50/50 mix of antifreeze and distilled water).

3. Replace Thermostat (if faulty)

Tools Required: Socket set, torque wrench, and gasket scraper.
Locate the thermostat housing, usually near the engine intake manifold.
Remove the bolts securing the thermostat housing and carefully lift it off.
Remove the old thermostat and clean the mounting surface.
Install the new thermostat in the proper orientation and replace the gasket.
Reattach the thermostat housing and torque the bolts to the manufacturer's specifications.

4. Inspect and Replace Radiator Fan

Tools Required: Multimeter, socket set.
Use a multimeter to check for power at the fan connector while the engine is running.
If the fan does not operate, it may need to be replaced. Remove the fan shroud and disconnect the electrical connector.
Install the new fan and reassemble the fan shroud.
