REMOVAL AND INSTALLATION (Continued)
CAUTION: When installing the serpentine acces-
sory drive belt, belt must be routed correctly. If not,
engine may overheat due to water pump rotating in
wrong direction. Refer to (Fig. 44) for correct
5.2/5.9L engine belt routing. Or, refer to the Belt
Routing Label located in the engine compartment.
The correct belt with correct length must be used.
(a) Install generator. Tighten bolts to 41 N·m (30
ft. lbs.) torque.
(b) Install support bracket (generator mounting
bracket-to-intake manifold) (Fig. 40). Tighten bolts
to 54 N·m (40 ft. lbs.) torque.
(c) Position drive belt over all pulleys except
idler pulley (located between generator and A/C
compressor).
(d) Attach a socket/wrench to pulley mounting
bolt of automatic belt tensioner (Fig. 41).
(e) Rotate socket/wrench clockwise. Place belt
over idler pulley. Let tensioner rotate back into
place. Remove wrench. Be sure belt is properly
seated on all pulleys.

Do not waste reusable coolant. If the solution is
clean, drain the coolant into a clean container for
reuse.
WARNING: CONSTANT TENSION HOSE CLAMPS
ARE USED ON MOST COOLING SYSTEM HOSES.
WHEN REMOVING OR INSTALLING, USE ONLY
TOOLS DESIGNED FOR SERVICING THIS TYPE OF
CLAMP, SUCH AS SPECIAL CLAMP TOOL (NUMBER
6094) (Fig. 45). SNAP-ON CLAMP TOOL (NUMBER
HPC-20) MAY BE USED FOR LARGER CLAMPS.
ALWAYS WEAR SAFETY GLASSES WHEN SERVIC-
ING CONSTANT TENSION CLAMPS.
CAUTION: A number or letter is stamped into the

CAUTION: When removing the radiator or A/C con-
denser for any reason, note the location of all radi-
ator-to-body and radiator-to-A/C condenser rubber
air seals (Fig. 47). These are used at the top, bot-
tom and sides of the radiator and A/C condenser.
To prevent overheating, these seals must be
installed to their original positions.
(1) Disconnect the negative battery cable at bat-
tery.
