How to service and repair the coolant reservoir, specifically the degas bottle on Lincoln MKX?

You should start by releasing pressure from the cooling system through careful counterclockwise rotation of the pressure relief cap by half a turn before you remove it. Hose clamp pliers enable clamping the lower degas bottle hose before using a suction device to drain coolant from the degas bottle. Place the degas bottle hoses out of the way before disconnecting the top and bottom hoses. Untighten the degas bottle-to-washer bottle bolt before removal but tighten it to 9 Nm (80 lb-in) torque when replacing it. To remove the degas bottle begin by unscrewing its two securing bolts before tightening them to 9 Nm (80 lb-in) when reinstalling. Put the procedures in reverse order to reinstall the degas bottle while filling it with recommended coolant mixtures to reach proper fill marks.
