Just flush the core and be done with it.
114 degrees is nothing really, especially since you are getting no heat removal thru the heater, were did the 40 degree difference go?
1.) Thx. Will do.
2.) I have no @^#% idea. Agree, 40F is a big diff. It's not coming into the cabin. There is normally always hot coolant flow thru the core though, because there is no hot-coolant-shut-off-valve in the plumbing, only a damper/door that directs airflow from the core.
Thanks, I'll get into it after I get the NYS Inspection done today.
