Packard 1940-1956 Dual stream Underseat Heater Core
HC Packard 40-56 underseat-1 core
The underseat dual stream heater cores in this period had a single heater core. We designed a second version with two cores for more heat
We have seen the Packard underseat Dual Stream heater core in the 1955 and 1956 most frequenlty but believe it may have been available as early as 1940. This core design is a better heat exchanger than the cellular film core but we can make the heater core larger for more heating if required.
