AC systems

[Ron Earp]

And interesting line in the IT rules:

9.1.3e
Air conditioning systems may be removed in whole or in part.

"Air conditioning systems" isn't defined in the GCR Glossary. A look through the Ford Factory Shop manual defines AC as:




Over and over in the manual. Lots of pictures of the AC housing, complete AC system, internal AC system, etc. and they all reference this:



And then of course you have 9.1.3g which states:
Engine coolant fluid, coolant/heater hoses and clamps may
be substituted. Heater hoses may be plugged. Heater water
control valve(s) may be added or substituted. Heater core and
hoses shall not be removed.

Indicating the heater core MUST remain. Along with hoses, but I haven't seen a car with heater hoses in a long time.

I think one could make an argument that you could stick my heater core through the firewall and hang it in space, with hoses, and be legal. And, might could argue you could toss the entire thing, heater core too, based on 9.1.3d because evidence can be provided that the heater core is included in the AC system assembly according to factory docs.

In the end I will do neither and keep the system. The box weighs something like 3.X lbs, the motor is 3.5 lbs, and the heater core is around 2.5 lbs. That isn't a lot of weight to have a working defroster.
