General Information
Optional Equipment Compatibility
While VMAC strives to design systems compatible with optional OEM equipment
(such as running boards), it is impractical to develop systems that accommodate
every OEM and aftermarket option or add-on. Whenever possible, VMAC
endeavors to advise of compatibility issues in the “Additional Application
Information” section of the manual. Even when specific optional equipment is
determined by VMAC to be incompatible, it does not preclude the vehicle upfitter
or end user from modifying the optional equipment to make it compatible with
the installed VMAC system. VMAC does not warranty or accept responsibility or
liability for the fitment, function or safety of any products modified in any way not
expressly outlined in the installation manual.
Before Starting
Read this manual prior to beginning the installation to ensure familiarity with the
components and how they will fit on the vehicle. Identify any variations from the
application list such as vehicle model, engines, or optional equipment (e.g., dual
alternator, active steering assist, etc.).
Open the package, unpack the components and identify them using the Illustrated
Parts List (IPL) included in the Fastener Pack.
Hose Information
Depending on other installed equipment, it might be necessary to move the air/oil
separation tank from its intended location. The hoses used in VMAC compressor
systems have a specific inner liner that is compatible with VMAC compressor oil.
Use of hoses other than those supplied or recommended by VMAC may cause
compressor damage and may void your warranty. Please contact VMAC for
replacement hoses and further information.
Ordering Parts
To order parts, contact a VMAC dealer. The dealer will ask for the VMAC serial
number, part number, description and quantity. Locate the nearest dealer online at
www.vmacair.com/dealer-locator or call 1-877-912-6605.
Note and label all parts that are removed from the vehicle as many
of the OEM parts will be reused during the installation of the VMAC
system.

Special Tools Required
• Pneumatic fan wrench removal set (such as Lisle® 43300) or a manual fan
pulley holder (such as KD Tool® KD3900)
• Vehicles with adaptive power steering: Pulley removal tool kit (such as a Lilse
39000, Jet H3565 or Performance Tool 389708 or equivalent).
Torque Specifications
All fasteners must be torqued to specifications. Use manufacturers’ torque values
for OEM fasteners.
The torque values supplied in Figure 1 are intended for VMAC supplied components,
or for use as a guide in the absence of a torque value provided by an OEM.

Preparation for installation is very important. Missing a step
or an item can cause problems in the installation or damage to
components.
☑
Check off each item as it is completed so that no steps are
missed.
When dissembling engine components, cover the openings to
prevent debris from entering the system.
Apply Loctite 242 (blue) to all fasteners (except nylon lock nuts)
unless otherwise stated.

Relocating the ABS Hydraulic Control
Unit (HCU)
Failure to follow these instructions may result in brake system
contamination, component damage, and/or death.
If there is any concern that air may have entered the brake system,
consult a local Ford dealer or licensed repair facility for vehicle
specific HCU brake bleeding instructions.
Use extreme caution while adjusting the brake lines to prevent
damaging them.
If there is any concern that the brake lines may have been kinked or
damaged in any way, contact a local Ford dealer or licensed repair
facility to have the issues rectified.
Depending on the application, the following steps may not be
necessary. If the HCU is mounted towards the firewall
(Figure 20 on page 18), proceed to the next chapter. If the HCU
bracket is mounted using the holes shown in Figure 15, follow the
steps in this chapter.
Do not allow the brake master cylinder to run dry during these steps
as the master cylinder may be damaged if operated without fluid.
Use only clean brake fluid from an unopened container that meets
Ford specifications.
It may be necessary to rotate the brake lines that connect the
master cylinder to the ABS HCU module to avoid kinking the flexible
rubber hoses as the HCU is shifted to its new position. The following
process will help avoid air entering the brake system as brake fluid
will be forced out of the system rather than air permitted to enter
the system.
Do not pump the brakes at any time while the brake lines are loose
as air may be drawn into the system.
Have an assistant gently depress the service brake as the brake
line is loosened, rotated into a relaxed position and then quickly
retightened. Adjust one brake line at a time. If there is a significant
amount of brake fluid escaping from the fitting, the pedal is being
pressed too hard and/or the fitting has been loosened too much.
