Reply To: 1931 Series 43 Passenger Heater

[Edgar Minnie]

Cadillac offered a factory hot water heater in 1930 made by Harrison. They also offered an exhaust heater that year also. Proper plumbing of a heater is to place a fitting on the high pressure side of the water pump, run coolant through the heater, and then return somewhere on the low pressure side. They should also have a shut off valve for the summer. Gasoline heaters made by south wind were popular from 1927, and they work great, in 1984 I bought a NOS gas south wind in the box at Hershey and used it in a CJ7…….the only CJ7 in the world that was comfortable with a soft top in the winter.
