19. Install distributor cap. Coat the inside of each spark plug wire connector with silicone grease with a
small screwdriver, and install the wires. Connect distributor wiring harness.
The following procedures are for installing the upper intake manifold.
1. Apply sealing compound to the joining surfaces of the upper and lower intake manifolds. Install the
upper intake manifold gaskets.
2. Install upper intake manifold (plenum) assembly. Tighten the bolts in two steps to specifications.
3. Connect all vacuum hoses to fittings on upper intake manifold.
4. Engage electrical connections at throttle body, EGR pressure sensor, intake manifolds sub harness to
EEC main harness.
5. Install and adjust throttle linkage bracket assembly and cover.
6. Connect hoses from water outlet to radiator, and bypass hose from thermostat housing rear cover to
intake manifold.
7. Connect battery negative cable.
8. Refill and bleed the cooling system.
9. Recheck ignition timing and reset engine idle speed to specification.
10. Run engine at fast idle and check for coolant and oil leaks.
3.0L Engine
The throttle body is cast integral to the upper intake manifold. To remove the upper intake manifold,
refer to Section 5 for throttle body removal.
1. Drain the cooling system (with the engine cold).
When draining the coolant, keep in mind that cats and dogs are attracted by ethylene glycol 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 drain the coolant into a sealable container. Coolant should be reused unless
it is contaminated or several years old.
2. Disconnect the battery ground cable.
3. Depressurize the fuel system and remove the air intake throttle body as outlined in Section 5.
4. Disconnect the fuel return and supply lines.
5. Remove the fuel injector wiring harness from the engine.
6. Disconnect the upper radiator hose.
7. Disconnect the water outlet heater hose.
8. If equipped with distributor ignition, disconnect the distributor cap with the spark plug wires attached.
Matchmark and remove the distributor assembly.
9. If equipped with distributorless ignition, Label and remove the spark plug wires from the coil pack,
then remove the coil pack.
10. Remove the valve covers. Loosen retaining nut from cylinder #3 intake valve and rotate rocker arm
fulcrum away from valve retainer. Remove the pushrod.
11. Remove the intake manifold attaching bolts and studs (Torx® socket required).
12. Lift the intake manifold off the engine. Use a plastic mallet to tap lightly around the intake manifold
to break it loose, if necessary. Do not pry between the manifold and cylinder head with any sharp
instrument. The manifold can be removed with the fuel rails and injectors in place.
13. Remove the manifold side gaskets and end seals and discard. If the manifold is being replaced,
transfer the fuel injector and fuel rail components to the new manifold on a clean workbench. Clean
all gasket mating surfaces.
