Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to prevent electrical shorts.

2. Check and Refill Coolant

Remove the coolant reservoir cap and check the level.
If low, mix the appropriate coolant with distilled water (usually a 50/50 mix) and fill to the recommended level.

3. Inspect and Replace Thermostat

Tools Required: Socket set, torque wrench, gasket scraper.
Drain the coolant to a safe level below the thermostat.
Remove the thermostat housing bolts and lift off the housing.
Take out the old thermostat and compare it with the new one for compatibility.
Install the new thermostat, ensuring it is oriented correctly.
Reattach the thermostat housing and torque the bolts to manufacturer's specifications.

4. Clean Radiator

Tools Required: Hose, soft brush, cleaning solution.
Using a hose, spray water through the radiator fins to remove debris.
If heavily clogged, apply a cleaning solution specifically designed for radiators and rinse thoroughly.

5. Test Cooling Fan Operation

Reconnect the battery and start the engine.
Allow the engine to reach operating temperature and observe the cooling fan.
If the fan does not engage, check the fan relay and wiring, and replace the fan if necessary.

6. Final Check and Refill Coolant

Recheck the coolant level after repairs and top off if necessary.
Start the engine and allow it to reach operating temperature while monitoring for leaks and proper fan operation.
