| A/C SYSTEM |
| |
| |
| INTRODUCTION TO A/C |

Today's A/C systems are far better than systems
from only 10 years ago. The refrigerant is different and that means everything
else is too. The new GEN II systems (Read more about GEN II) use
solid state servos not inefficient vacuum actuators, the evaporators cores are
more efficient the condensers transfer heat better, the compressors are
smaller, quieter and put out more pressure, the hoses have an inner liner to
with stand the higher pressure and to hold in the smaller molecule HFC-134A
refrigerant. Click on the link (Basic A/C) to get more Basic A/C info from Vintage Air.
This system runs HFC-134A refrigerant and PAG
(Poly Alkaline Glycol) oil. Charging info

This is a cut away of the Sanden
508 compressor. With 5 pistons this thing can compress some serous
R134A 8cfm to be exact. |
This is a cut away of a dryer with the
desiccant (water remover) missing. The dryer removes condensation from the
R134A to keep the system running smoothly. |

| THE IMPORTANCE OF INSULATION |
A/C basically removes heat from the air in your
Bronco. If you have holes in the floor or firewall or have bad weather
striping then it will be harder to get the Bronco cool and keep cool. If you
have all of the holes plugged and good weather striping then you should be
fine. When you add insulation, not only do you help cool your Bronco faster it
also makes your Bronco quieter making a much more comfortable ride all the way
around.
Keep Cool insulation has many benefits
over insulation that is much thicker. Keep Cool is an olefin film-covered, low
density, irradiation cross-linked closed-cell polyolefin foam insulation. What
does that mean? The olefin film coating reflects the transfer of radiant heat,
while the closed cell foam insulates against convective heat transfer. It
keeps you harm in the winter and cool in the summer this 1/4 thick
insulation will reduce noise levels by over 40% compared to fiberglass
insulation.
-
It is a better thermo insulator than
fiberglass.
-
It has a melting point of 350* and has no flash
point so it will not catch fire like fiber insulation.
-
It will not electricity in the event of an
electrical short.
-
It is gas, oil chemical resistant and flame
retardant.
-
It reflects 100% of sound waves it receives
therefore keeping unwanted noise out while keeping music and conversation in.
-
It will not absorb moisture and will not rot or
deteriorate.

| BC BRONCOS A/C SYSTEM |
This is not the same A/C system everyone else
sells, it was designed by BC Broncos fit
in the 66-77 Ford Bronco and is built exclusively for us by Vintage Air. This
system is not just A/C it is also heat and defrost. The A/C comes out of the
vent and the heat comes out of the vents and out at the floor also and the
defrost comes out the top of the dash. Using GEN II technology
the system is controlled by servos (Read more about GEN II) for
more air flow and ease of installation. We wanted to make sure that the
evaporator (the part behind the dash) allowed for the use of a stock type
glove box or Tuffy box without trimming the evaporator, glove box or
dash. We also needed it to be tucked up under the dash out of the way as much
as possible. To get the A/C hoses through the fire wall you need to cut a hole
with what ever system you use, so we decided to do it with some style and make
it more of a center piece than an eye sore, the kit comes with an Aluminum
bulk head and fittings to run the A/C and heater hoses through the firewall,
keeping all of the hose connections behind the engine giving a less cluttered
appearance. The evaporator is mounted using two of the original heater
mounting holes. This system is extremely efficient thanks to the super cooler
condenser and HFC-134 refrigerant.

| LETS COMPAIR OTHER A/C SYSTEMS |
First off we are not trying to talk bad about the quality of anyone's A/C system. This comparison is to show you about the different features so you can make an informed decisions before you buy. A/C is a big step you don't want to buy a system and go through the time to install it only to find out that there is something that fits better, is cleaner and easier to install.
The Vintage air Sure fit system for the Bronco (74076-LFU-A) sold by Vintage Air,Jeff's, toms, Bronco hut and if you want it BC can sell it to you also.
Installed the system looks like this in the engine compartment. The Vintage air kit puts the compressor on the passenger side this customer moved it to the driver side and had to add on to the hoses. As you can see the system Adds a lot of clutter to your engine compartment, and requires you to run the A/C and heater hoses through the passenger air vent. This kit has a smaller condenser and puts the dryer between the grill and core support. This system also uses a universal bracket (AKA lots of fab work) The compressor is only Vbelt (but probably could be changed out when ordered).


The BC Broncos A/C system (made for BC Broncos by Vintage air) for the Bronco (75-21100 vbelt 75-21101 serpentine) sold by BC Broncos and special ordered through Wild Horses.


Installed the system looks like this in the engine compartment. The BC Broncos A/C kit puts the compressor on the driver side so you can change over to serpentine later. As you can see the system does not really add a lot of clutter to your engine compartment. This system requires you to run the A/C and heater hoses through a bulk head located behind the engine at the firewall . This kit has a bigger condenser and puts the behind the battery. This system also uses our multi steer (compressor/power steering bracket)bracket ( the same one that comes in our power steering and serpentine belt kits if you have one of thoes kits let us know and we will sell you the A/C kit without a Bracket saving you some money). You can order the kit for Serpentine or V belt.
The Arizona air kit is an A/C only kit sold by Toms. See the classic under dash A/C kit below to compair the two

| UPGRADE IN-DASH STREAMLINE VENTS |
These are the vents we use on our Broncos and
are the most common vents people ask for. These vents feature Polished
aluminum bodies and plastic louvers that move up and down and left to right.
We run two of the 4" vents on the side and the 4.875" vent in the center.
Even though it looks more uniform to run 4
vents, the system is designed to run 3 vents we tried using a Y hose splitter
but it severely limited the air flow to the two center vents so we don't
recommend running it that way.

| SUPERFLOW CONDENSER |
This new SuperFlow condenser does
an amazing job at cooling. The importance of this unique new micro tube design
and its improver refrigerant flow cannot be over emphasized.
(As the illustration to the right shows) providing increased refrigerant
contact with the micro tube walls and multiple passes per circuit for low
restriction pathway, the SuperFlow condenser provides up to 40% more capacity
than a comparably sized tube and fin condenser. This
is the condenser that comes with the BC Bronco A/C kit, it measures
20.75" tall X 14" wide X .75 thick. This condenser is meant to be installed
vertically, if you need to mount it differently let us know and we can
exchange it for the horizontal condenser.
We now have two options for condensers the standard black and aluminum, we now have this option for the guys that are running Aluminum radiators and want their condenser to match.

| ALUMINUM BULKHEAD |
| The Aluminum Bulkhead is a great way to have the hoses go
through the fire wall, this way you don't have to worry about the hose
getting cut on sharp metal or putting ugly grommets around the hole. This
bulkhead has 4 ports two for the A/C lines and two for the heater hoses. We
know this increases the cost of the kit but we feel it is worth it. One you
mount the bulkhead you can remove any or all of the lines from either side
and the bulkhead stays in place. This is a nice feature if you need to
remove the complete engine you can still keep the hoses on the inside
intact, just a plug the out side to keep the system sealed. This bulkhead and fittings come in the BC Broncos
A/C kit. |

The dryer needs to be installed standing up in order for it to work
correctly if you want to do a custom install with a horizontal dryer let us
know and we can upgrade your kit but we designed the kit to work with the
vertical dryer.
Remember when installing the A/C kit and hoses do not open
the dryer until you are ready to install it in a closed system. Leaving the
system open will cause the dryer to PULL MOISTURE OUT OF THE AIR AND MAKE IT GO BAD.

switch will cut off at the same pressures but will also turn on an electric
fan when the pressure reaches 220psi helping to cool the system. The BC Broncos A/C system comes with a Binary switch but can be upgraded if needed.

| The classic under dash A/C unit is just like some of the
dealer installed units that came in Broncos, In fact Vintage Air installed
A/C in Broncos for some of the dealers in the San Antonio area in the
1970's. The Mark IV features an all steel case built from the original
tooling. This is a great option if you want to add A/C only and not change
out your heater or if you want to have a more retro looking set up. You can
buy just the unit or a hole kit.

We wanted
to cover Five major points when we designed this bracket.
1st We wanted it to work on
all 289,302, 5.0 or 351W engines.
2nd We wanted to make sure
it fit all popular power steering pumps including. Saginaw with caned ham or ford van reservoir, mid 70's- 80's plastic reservoir pump and Stock.
3rd We wanted to be able to
use this system for "V" belt and serpentine belt setups, with
the option to go from one to the other by just changing the pulleys.
4th To be able to bolt on a Sanden A/C compressor without any extra brackets.
5th Making sure it all fits
under the hood as low as possible and out of the way of the steering
box.
It works with your choice of serpentine
or V belt pulleys on all engines that are commonly put in Early Broncos and
is set up for a Sanden 508 compressor for A/C or on board air.
Options We are
also testing two different add on brackets to bolt up a York compressor and
a separate power steering pump for hydro boost.
The BC Broncos A/C system comes with a
multi steer bracket for the Sanden 508 compressor.
