Coolant in oil pan JD6059

Went to do a little road work today. Checking fluid levels and engine oil too high. No diesel smell, coolant low, drain about two gallons of coolant out of oil sump. Sure glad I always do fluid checks first thing.

Backround: Parked one month ago after plowing snow for 5 hours. Had to replace block heater first. Added coolant. Did notice a chirping noise towards the end of day. Nothing apparent when I looked around. Noted engine running a little warmer, not hot.
Did note on today's oil check...
