Performing a coolant drain, flush, and refill on your Chevrolet Captiva manufactured from 2006 to 2018 is essential for maintaining optimal engine performance and preventing overheating issues. To begin, ensure the engine is cool and park on a level surface. Locate the radiator drain plug underneath the radiator and position a drain pan beneath it. Slowly loosen the plug to allow the coolant to drain completely. Next, refill the radiator with a mixture of coolant and distilled water, following the manufacturer's recommended ratio. Start the engine and let it run with the radiator cap off to circulate the coolant. Bleed any air bubbles, top up the coolant reservoir, and check for leaks before securing the radiator cap.
