Any kinks or sharp bends in the refrigerant plumb-
ing will reduce the capacity of the entire air condi-
tioning system. Kinks and sharp bends reduce the
flow of refrigerant in the system. A good rule for the
flexible hose refrigerant lines is to keep the radius of
all bends at least ten times the diameter of the hose.
In addition, the flexible hose refrigerant lines should
be routed so they are at least 80 millimeters (3
inches) from the exhaust manifold.
OPERATION
The refrigerant lines used for this vehicle are com-
mon between the two optional engines in order to
reduce complexity. The following refrigerant lines are
available for service replacement on this vehicle:
• Discharge line - The discharge line is a flexible
hose type line that is connected from the discharge
port of the compressor to the inlet (upper fitting) of
the condenser. It has no serviceable parts except the
rubber O-ring seals used on the fittings at each end
of the line. If the discharge line is damaged or faulty,
it must be replaced (Fig. 7).
