Stop in for a cup of coffee

My barracuda smells like a coolant leak if its gets hot enough. My temporary solution is ginger pills. The ones from a GM dealer supposed to be the best. Barr's sells a version thats at most local stores.
My problem is I drive it 500 miles one way to work when the boat is working stateside. I have already blown the head gaskets once from an overheat due to a cooling fan failure. Torque to yield bolts and ARP was out of stock at the time.
