Installing the Air Oil
Separator Tank (AOST)
Dependent upon other installed equipment, it may be necessary to
move the AOST 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 the warranty.
Figure 20 — AOST installed
Front of vehicle
The AOST must be level for proper air/oil separation, and to ensure
that the oil level will display accurately in the sight glass.
Apply Loctite 242 (blue) to all fasteners (except nylon lock nuts)
unless otherwise stated.
Installing the AOST
The AOST will mount to the passenger side frame rail, with the brackets straddling
the transmission cross member (Figure 20).
☐
Using the OEM mounting hardware, replace the (×2) front running board
brackets with the supplied low profile brackets.
