3/16 in. (5mm) bead of RTV sealant on the
front and rear ridge of the cylinder case.
20. Hold the gaskets in place by ex tending the RTV bead up onto the gasket
ends. Use sealer at the water passages.
21. Position the intake manifold as sembly onto the engine and install the
intake manifold-to-cylinder head bolts. Torque bolts in sequence to 25-45
ft. lbs. (34-61 Nm).
22. Connect the heater hose to the intake manifold.
23. Connect the upper radiator hose to the thermostat housing.

1988-1992 MODELS
1. Disconnect the negative battery cable.
2. Drain the cooling system.
3. Remove the air cleaner.
4. Remove the throttle body.
5. Label and unplug all vacuum hose and electrical connections on the manifold.
6. Disconnect the upper radiator hose from the manifold.
7. Mark the distributor position and remove it.
8. Remove the EGR valve, if necessary.
9. Remove the intake manifold bolts and studs.
10. Remove the manifold and discard the gaskets.
To install: 11. Make sure the sealing surfaces are clean.
12. Install the gaskets and apply a
3/16 in. (5mm) bead of RTV sealant on the
front and rear ridge of the cylinder block.
13. Hold the gaskets in place by ex tending the RTV bead up onto the gasket
ends. Use sealer at the water passages.
14. 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.
15. Install the intake manifold attach ing bolts. Tighten them, using the proper
sequence, to 89 in lbs. (10 Nm).
16. Final torque the bolts, using the proper sequence, to 35 ft lbs. (47 Nm\
).
