1985 PT-40 Radiator Question

[Jay Darst]

Wayne,

< suffice?>>

By setting the winter/summer switch to winter, the anti freeze is
circulated to all the heaters.

The on/off switch at each unit enables the fan that blows air thru
the heater core. The Hi/Low switch controls the fan speed. Then the
thermostat on the wall labeled "Chasis Heat" controls all the fans.



<

Nope, never did any bleeding of the heater system.
