The recommended 50-50 mixture of anti-freeze and water while giving good protection against freezing (-34F), does not provide the best medium for transferring heat. A lesser amount of anti-freeze will help with the heat transfer. I see where you live in Chicago, and need the freeze protection during the cold months.

You could change out your winter mixture and replace it with a weaker mixture for warm weather driving. I would not recommend straight water as it will rust and corrode your cooling system. Maybe straight water with a anti-rust/anti-corrosion/lubricant additive would work Maybe the water wetter product is something to look into.

A lower temperature thermostat (160F) will get the coolant circulating sooner and will give more operating temperature range, but will not in its self prevent over heating (as has been previously mentioned).

These are simple changes you can explore before going into more complicated (and expensive) remedies. Just a suggestion.

Frustrating to not be able to fully enjoy your Packard during the peak driving months.
