How to remove actual bus heater for 1990 bb international

[Bus.siix]

Hi! Me and my wife are trying to figure how to remove the bus heater in our 1990 blue bird! SEE when we got the bus the heater was already removed and drained but we still have to take the main source out! How do we do this ? Are there wires we can't cut and what wires do we cut ? Please if you know anything let me know !!!

Start unscrewing the parts on it. The wires should lead to your switches. Remove the wires that run to the heater. That's how I removed mine. Just started taking it apart. I would disconnect the battery just in case.

Have you considered that the heater you are pulling out is also the defroster?

They do come in handy at times.

I have a small hurri hot next to the drivers seat in my 1991 Bluebird and it is a electric heater. You should definetely disconnect the battery!.
Why are you removing the heater???

I know your not asking me, but I removed my heater because it was 30 years old and in horrible shape. In replacing mine with a 40,000 btu unit from Jegs that is much smaller and hooks back up to the engine coolant lines I left.

I'll run new defroster and heat vents for it.

We removed the panels yesterday to the heaters/defrosters up front (which don't work anyway since the coolant lines were removed by the previous owners). Inside was completely disgusting and it's open to the road below! Even if it needs air wouldn't it be better to have a filter between the road air and the box? The air ducts are toast anyway; there's no point in trying to clean them instead of replace.

I would think the new ones would be smaller and more efficient but are they more contained? Can I do anything with the old ones?

How about the stop sign arm motor- any alternative uses for that?

That is the one I've bought. A filter is a good idea. I don't know how I would incorporate one though. My bus had all the heatees on the driver's side. Up front there is a vent that allows the air to come in for the main heater.

You can scrap the old heater I guess. I'm not sure if there is any value to it. My stop sign arm was already removed.

I did have the front arm flapper thing off the front bumper. I just removed it since I didn't need it.
