Be sure to keep all the components in t he exact order of removal so they may
be installed in there original location; adjust the valve lash after replacing the
rocker arms. Coat the replacement ro cker arm and ball with engine oil before
installation.
Rocker arms studs that have damaged thr eads or are loose in the cylinder
heads may be replaced by reaming the bore and installing oversize studs.
Oversizes available are 0.003 in. (0. 076mm) and 0.013 in (0.33mm). The bore
may also be tapped and screw-in studs installed. Several aftermarket
companies produce complete rocker arm st ud kits with installation tools.
The 2.5L engine use bolts instead of studs, 2.8L and 3.1L engines use threaded
studs, the 3.4L, 5.0L and 5.7L engines use press fit studs.
EXCEPT 2.5L ENGINES 1. Disconnect the negative (-) battery cable.
2. Remove the rocker arm cover as outlined in this section
3. Remove the rocker arm nuts, balls and rocker arms. Place components
in a rack so they can be reinstalled in the same location.
To install: 4. Coat the bearings surf aces with a thin coating of Molykote® or its
equivalent.
5. Install the pushrods and make sure the rod is in the lifter seat.

Fig. 8: Lifting out the radiator
1. Disconnect the negative battery cable.
2. Drain the cooling system.
CAUTION - When draining the coolant, keep in mind that cats and dogs are
attracted by the ethylene gl ycol antifreeze, and are quite likely to drink any that
is left in an uncovered container or in puddles on the ground. This will prove
fatal in sufficient quantity. Always drai n the coolant into a sealable container.
Coolant should be reused unless it is contaminated or several years old.
3. Remove the air inlet ducts and air cleaner, if necessary.
4. Remove the electric cooling fan, if equipped.

radiator lower cradles are locat ed properly in radiator recess.
14. Refill the cooling system. Check the engine oil and transmission fluid
levels, if necessary. Run engine for a short period of time and check for
leaks.
ENGINE OIL COOLER
The engine oil cooler consists of an adapter, bolted to the engine block, to
which the oil filter is scr ewed onto. The adapter has 2 hoses which attach to the
oil cooler and the radiator , these hoses are the inlet and return lines.
REMOVAL & INSTALLATION 1. Disconnect the negative battery cabl e. Drain the cooling system into a
suitable container.
CAUTION - When draining the coolant, keep in mind that cats and dogs are
attracted by the ethylene gl ycol antifreeze, and are quite likely to drink any that
is left in an uncovered container or in puddles on the ground. This will prove
fatal in sufficient quantity. Always drai n the coolant into a sealable container.
Coolant should be reused unless it is contaminated or several years old.
2. Remove the radiator, if the oil c ooler is to be repaired or replaced,
otherwise remove the engine oil cooler from the radiator as necessary.
3. Remove the oil filter.
4. Remove the hoses from the oil cooler adapter.
5. Unscrew the oil cooler adapter re tainer and remove the assembly.
Discard the gasket.
6. Installation is the reverse of t he removal procedure. Use new gaskets.
ELECTRIC COOLING FAN
REMOVAL & INSTALLATION 1. Disconnect the battery ground cable.
2. Remove the air cleaner and ducts, if necessary.
3. Unplug the fan harness connector.
4. Remove the fan frame to radiator support mounting bolts and remove the
fan assembly. Some models are retai ned by clips. Remove these, then
slide the fan assembly from the radiator.
5. Install the cooling fan frame to t he radiator support bolt. Reconnect the
wiring harness, the negative battery cable and check fan operation.
BELT-DRIVEN COOLING FAN
REMOVAL & INSTALLATION 1. Disconnect the negative battery cable.
2. Remove the fan shroud, as required.

When servicing the engine, be absolutely sure to mark vacuum hoses and
wiring so that these items
may be properly reconnected during installation. Also,
when disconnecting fittings of metal lines (fuel, power brake vacuum), always
use two flare nut (or line) wrenches. Ho ld the wrench on the large fitting with
pressure on the wrench as if you were tightening the fitting (clockwise), THEN
loosen and disconnect the smaller fitting fr om the larger fitting. If this is not
done, damage to the line will result.
CAUTION - When draining the coolant, keep in mind that cats and dogs are
attracted by the ethylene gl ycol antifreeze, and are quite likely to drink any that
is left in an uncovered container or in puddles on the ground. This will prove
fatal in sufficient quantity. Always drai n the coolant into a sealable container.
Coolant should be reused unless it is contaminated or several years old.
