To install: 25. Apply a
3/16 in. (5mm) bead of RTV sealant on the front and rear ridges of
the block. Make sure the surfaces are clean.
26. Install the new gaskets on the cylinder heads. Hold the gaskets in place by extending the RTV bead up onto the gasket ends.
27. Install the intake manifold.
Sealing of the intake mani fold to the "V" of the engine is obtained by employing
an intermediate torque specification to a ll the attaching bolts, alternately, in the
proper sequence. This step is used to rock the manifold into place before
applying the final torque figur e. Failure to follow this two-step procedure can
result in possible leaks.
28. Install the intake manifold attach ing bolts. Tighten them, using the proper
sequence, to 89 in lbs. (10 Nm).

To install:
11. Make sure the mating surfaces are clean.
12. Install a new gasket, if applicable.
13. Position the exhaust manifold onto the engine. Torque the attaching bolts
to:
• 1982-1992 V6 engines: 25 ft lbs. (34 Nm)
• 1982-1992 V8 engines: 26 ft lbs. (35 Nm)
14. Bend the locktabs over the bolts.
15. Connect the exhaust pipe to the manifold.

WATER PUMP
REMOVAL & INSTALLATION
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.

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.
