Antifreeze

I noticed a problem with low start crank about a month ago and thought I should look into the batteries. I found both nuts on negative terminals hand loose from the time the motor was replaced. Both battery status are green. This lead me to believe the batteries are not properly grounded and they are not getting charged properly. Problem solved!
So then I noticed the radiator overflow had low antifreeze. What is the best antifreeze out there or what is recommended by you guys?

How low does the coolant level show? The old minimum line is now the maximum line - Ford made this revision some time ago in response to the coolant puking issues many were having. I'm surprised they didn't put a sticker on your degas bottle to reflect the change.

Yeah its a 06 F350 Diesel 4x4 LB. The coolant is below the minimum line while it sits in my driveway parked backwards on a decline (like my avatar pic).

I assume that's what you're seeing when it's cold? As long as it doesn't exceed the minimum mark when hot on level ground you are fine.

Motorcraft Gold is the correct coolant.
