The steep hills are where I'm having some issue in my civic (with grill open and full outlet venting). I did pull the a/c fan fuse, but don't know if it affects engine heating. How do you get cooling with the grill block closed, and limited outlet venting, especially when climbing steep hills in the heat?

That suction is developed by a wheel spinning within the close confines of a wheel housing. Having a skirt over the wheel well opening does help to increase that suction just as the housing around a squirrel cage blower helps to strengthen and direct its flow.
I get a small amount of cooling airflow through my radiator even with the grill block closed as some air leaks around the edges of the closed grill block. When climbing a long steep hill in the heat, I'll open the grill block and let the front wheel suction do its thing. Then when going down the other side I'll gradually close the block as the engine's heat production drops.
