Re: 22-23 series heater
Posted by BDeB On 2013/10/27 17:04:59
Here are some photos of a 22nd Series heater box.
Air flows up from the blower and into an internal plenum which directs the flow through the center of the core. There is a close fitting cover on the core that forces the air to turn 180 degrees and into the ducting inside the car. The internal cover is held in place by 4 rubber cushions that the outer cover presses against. There is very little room inside the heater box for the core to get tilted, but perhaps the flow could bypass the core if the inner cover was missing.
As far as screws on the outer cover, there are 7 of them, 2 of which are on the bottom side and hard to get to with the blower assembly in place.
