PRE-INSTALLATION INFORMATION
IMPORTANT: The Height Control Valve (HCV) and linkage are designed to maintain
the vehicle ride height as loads increase and decrease. Proper set up of the HCV(s) is
critical to the system performance. Prior to any assembly or disassembly, please read all
instructions. Should you feel unable to properly perform the installation and adjustments
of a Haldex Type CR HCV contact Haldex Technical Services or have a certified mechanic
install or adjust the valve.
CAUTION: Incorrect installation of valves and associated components can impair
suspension and vehicle performance. It is extremely important that the original equipment
manufacturer's specifications of a one- or two-HCV system are followed when installing
the air control system. Refer to vehicle and suspension manufacturer's instructions for
recommended valve location.
DO NOT install a single height control valve of any type if the suspension or vehicle
manufacturer specifies a two (2) height control valve system.
DO NOT use antifreeze or other solvents in air supply line. Use of
solvents or antifreeze can damage seals and voids the valve warranty.
ALWAYS use a Pressure Protection Valve (PPV) and filter such as the
Haldex Part Number 90554107. Attach PPV directly to the air reservoir
for supply to the Type CR HCV.
