REMOVAL AND INSTALLATION (Continued)
support bracket to lower frame crossmember (Fig.
50).
(17) Remove the remaining four bolts securing the
radiator upper crossmember to the body. Do not
remove the hood latch or hood latch cable from the
crossmember. Lift the crossmember straight up and
lay to the side.
(18) Equipped with air conditioning: Remove the
two A/C condenser-to-radiator mounting bolts (Fig.
50). These two bolts are also used to retain the side
mounted rubber air seals (Fig. 47). These seals are
compressed between the A/C condenser and the radi-
ator. The lower part of the air seals are compressed
between the radiator and the A/C condenser mount-
ing brackets (Fig. 52).
(19) Not equipped with air conditioning: Remove
the two bolts retaining the side mounted rubber air
seals (Fig. 47) to the radiator. The lower part of the
air seals are compressed between the radiator and
the radiator lower crossmember.
CAUTION: Note the location of all rubber air seals
(Fig. 47). To prevent overheating, they must be
installed back to their original positions.
(20) Disconnect the coolant reserve/overflow tank
hose (Fig. 51) at radiator.
(21) Remove upper radiator hose at radiator. A
special clamp tool (Fig. 45) must be used to remove
the constant tension hose clamps.
(22) 4.0L Engine Only: Remove the lower radiator
hose at the water pump end.
(23) To gain access to lower radiator hose clamp at
radiator, gently lift the radiator a slight amount.
Remove hose clamp and hose.
(24) The lower part of radiator is equipped with
two alignment dowel pins (Fig. 50) (Fig. 52). They
are located on the bottom of radiator tank and fit
into rubber grommets. These rubber grommets are
pressed into the radiator lower crossmember.
WARNING: THE AIR CONDITIONING SYSTEM (IF
EQUIPPED) IS UNDER A CONSTANT PRESSURE
EVEN WITH THE ENGINE OFF. REFER TO REFRIG-
ERANT WARNINGS IN GROUP 24, HEATING AND
AIR CONDITIONING BEFORE HANDLING ANY AIR
CONDITIONING COMPONENT.
(25) If equipped with an auxiliary automatic trans-
mission oil cooler, use caution when removing radia-
tor. The oil cooler lines are routed through a rubber
air seal on the left side of radiator. Do not cut or tear
this seal.
(26) Gently lift up and remove radiator from vehi-
cle. Be careful not to scrape the radiator fins against
any other component. Also be careful not to disturb
the air conditioning condenser (if equipped).

INSTALLATION
CAUTION: Before installing the radiator or A/C
condenser, be sure the radiator-to-body and radia-
tor-to-A/C condenser rubber air seals (Fig. 47) are
properly fastened to their original positions. These
are used at the top, bottom and sides of the radia-
tor and A/C condenser. To prevent overheating,
these seals must be installed to their original posi-
tions.
(1) Equipped with air conditioning: Gently lower
the radiator into the vehicle. Guide the two radiator
alignment dowels through the holes in the rubber air
seals first and then through the A/C support brackets
(Fig. 52). Continue to guide the alignment dowels
into the rubber grommets located in lower radiator
crossmember (Fig. 52). The holes in the L-shaped
brackets (located on bottom of A/C condenser) must
be positioned between bottom of rubber air seals and
top of rubber grommets.
(2) Not equipped with air conditioning: Gently
lower the radiator into the vehicle. Guide the two
radiator alignment dowels through the holes in the
rubber air seals. Continue to guide the alignment
dowels into the rubber grommets located in lower
radiator crossmember.
