How do you flush the coolant on a 2006 Chevy Equinox?

To flush the coolant on a 2006 Chevy Equinox, first, ensure the engine is cool, then remove the radiator cap and place a drain pan underneath the radiator. Open the petcock at the bottom of the radiator to drain the old coolant completely. After draining, close the petcock, fill the radiator with a coolant flush solution and water, run the engine to circulate the solution, then drain it again. Finally, refill the radiator with the appropriate coolant mixture and check for leaks.
