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).
29. Final torque the bolts, using the proper sequence, to 35 ft lbs. (47 Nm\
).
30. Install the EGR valve using a new gasket.
31. Connect the upper radiator hose to the thermostat housing.
32. Install new gaskets on the runner s and intake manifold. Make sure the
gasket sealing surfaces are clean.
33. Install the left side runners and finger-tighten the runner-to-manifold
bolts.
34. Install the left side manifold-to-runner bolt. Torque to 25 ft lbs. (34 Nm).
35. Install the right side runners. Fi nger-tighten the runner-to-manifold and
manifold-to-runner bolts.
36. Install the plenum and t he runner-to-plenum bolts.
37. Tighten the runner-to-manifold bolts to 25 ft lbs. (34 Nm). Start in the
center and work outwards.
38. Tighten the right side manifold-to -runner bolt to 25 ft lbs. (34 Nm).

3. Unplug the oxygen sensor and disconnect the exhaust pipe from the
exhaust manifold.
4. Remove the engine oil level dipstick and tube.
5. Remove the exhaust manifold atta ching bolts and remove the manifold.
To install: 6. Position the exhaust manifold onto the engine with a new gasket. Torque
the bolts, following the correct sequenc e, to 44 ft lbs. (60 Nm).
7. Install the engine oil level dipstick tube and dipstick.
8. Connect the exhaust pipe to the exhaust manifold.

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.
5. Disconnect the coolant overflow tank hose.
6. Disconnect upper and lower radiator hoses.
7. On vehicles equipped with automat ic transmission, disconnect and plug
the transmission fluid cooler lines.
8. Disconnect and plug the engine oil cooler lines, if equipped.
9. Remove fan shroud a ssembly, if applicable.
10. Remove the upper radiator mount screws.
11. Remove the radiator assembly by lifting straight up.
The radiator assembly is held at the bottom by tw o cradles secured to the
radiator support.
12. If installing a new radiat or, transfer the fittings from the old radiator to the
new radiator.

13. Replace the radiator assembly by
reversing the above steps. Check that
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.
