Coolant leaks when it's really cold

Do any of you have issues with coolant leaks on a truck that sits at 0F and below. Both my CM570 and CM870 leak from the water pump o-ring when it gets really cold. We've replaced o-rings several times to no real success. Lubed with lubriplate grease always and always using OEM Cummins o-rings.

Does anyone have a magic cure other than park the trucks inside?
