Remove the radiator cap and inspect for any debris or damage.
Drain the old coolant if contaminated, using a drain pan.
Refill with manufacturer-recommended coolant to the proper level.

3. Inspect and Replace Thermostat

Tools Required: Socket set, torque wrench, gasket scraper.
Remove the thermostat housing by loosening the bolts.
Take out the old thermostat and inspect it for damage.
Install the new thermostat ensuring it is oriented correctly.
Replace the gasket and reattach the housing, tightening bolts to manufacturer specifications.

4. Inspect and Replace Water Pump (if necessary)
