Never substitute fittings or hose. Follow the piping diagram provided with the system.
No matter what type of lubricant (oil) used in the system, always use mineral oil to lubricate the O-
Rings, and fittings. PAG oils will absorb moisture and become very acidic and corrosive. Mineral oil
will not absorb moisture and thus prevent corrosion.
Always use existing holes in the chassis frame. Never drill holes in the chassis frame.
Tie-Wraps may be used to bundle hoses and harnesses, but should never be used to secure hoses to
the vehicle.
Verify that the oil added to the air conditioning system is the same oil that is in the compressor. The
mixing of incompatible oils will damage your system.
