Cooling System Redux - Getting Started

Getting ready to swap out the original radiator, waterpump, thermastat housing, heater core hoses and belts on my 1985 Jeep CJ7 Laredo. Some pics before we get started. The original radiator is rusted out pretty badly (not to mention the visible crack on top) and is only a dual core unit. There isn't much on this CJ that isn't leaking but we'll take care of that. There is some rust showing at the entry/exit point for the heater core most likely from electrolysis between the copper heater core and steel firewall. We'll clean that up too.
