Relief Valve Replacement
l.Recover the refrigerant with a Recovery/Recycling/
Charging System (see page 22-59).
Remove the relief valve cover ('97 model), the relief
valve and the O-ring. Plug the opening to keep for-
eign matter from entering the system and the com-
pressor oil from running out.
O.RINGReplace.
RELIEFVALVE9.8 N.m {1.0 hgf.m,7.2 rbr.ftl
Put the cover on the relief valve so that the arrow
directs downwards as shown in the illustration
above ('97 model).
Clean the mating surfaces.
Replace the O-ring with a new one at the relief valve,
and apply a thin coat of refrigerant oil before
installing it.
Remove the plug. and install and tighten the relief
valve.
7. Charge the system (see page 22-61), and test its
performance (see page 22-561r.

charging ststion (see page 22-59)
Remove the front grille (see section 20).
Remove the coolant reservoii, but do not discon-
nect the reservoir hose Jrom the coolant reservoir
and the radiator.
Remove the bolts and the suction line bracket as
shown. Remove the bolts and the upper mount
brsckets from the radiator.
UPPER MOUNTBRACKETS
Remove each bolt, then disconnect the discharge
and condenser lines from the condenser, Plug or
cap the lines immediately after disconnecting them
to avoid moisture and dust contamination.

6. Remove the mounting bolts, then remove the con-
denser by lifting it up as shown. Be careful not to
damage the radiator and condenser fins when
removing the condenser.
Install in the reverse order of removal. Make note of
the following items.
. lf you're installing a new condenser, add refriger-
ant oil (sP-10) (see page 22-54]..
o Replace the O-rings with new ones at each fit-
ting, and apply a thin coat of refrigerant oil
before installing them. Be sure to use the right
O-rings for HFC-134a (R-134a) to avoid leakage.
. Be careful not to damage the radiator and con-
denser fins when installing the condenser.
. Be sure to install the lower mount cushions of
condenser securely into the holes,
. Charge the system (see page 22-61), and test its
performance (see page 22-56).
