FUEL INJECTION

1. Remove the air cleaner.
2. Drain the radiator.
3. Disconnect: a. Battery cables at the battery.
b. Upper radiator and heater hoses at the manifold.
c. Crankcase ventilation hoses as required.
d. Fuel line at the carburetor.
e. Accelerator linkage.
f. Vacuum hose at the distributor, if equipped.
g. Power brake hose at the car buretor base or manifold, if
applicable.
h. Temperature sending switch wires.
4. Remove the distributor cap and scribe the rotor position relative to the
distributor body, and engine.
5. Remove the distributor.
6. If applicable, remove the alternator upper bracket. As required, remove
the air cleaner bracket, and accelerator bellcrank.
7. Remove the manifold-to-head attachi ng bolts, then remove the manifold
and carburetor as an assembly.
8. Mark and disconnect all emission re lated items (e.g.: wiring, vacuum
hoses, etc.) which are connected to manifold mounted items.
9. If the manifold is to be replaced , transfer the carburetor (and mounting
studs), water outlet and thermostat (use a new gasket) heater hose
adapter, EGR valve (use new gasket) and, if applicable, TVS switch(s)
and the choke coil.
To install: 10. Before installing the manifold, thoroughly clean the gasket and sealing
surfaces of the cylinder heads and manifold.
11. Install the manifold end seals, folding the tabs if applicable, and the
manifold/head gaskets, using a s ealing compound around the water
passages.
Make sure that the new manifold gaskets match the old ones EXACTLY.
12. When installing the manifold, care should be taken not to dislocate the
end seals. It is helpful to use a pilo t in the distributor opening. Tighten the
manifold bolts to 30 ft. lbs. (40 Nm) for 5.0L or 20-25 ft. lbs. (27-34 Nm)
for 2.8L in the sequence illustrated.
13. Install the distributor with the rotor in its original location as indicated by
the scribe line. If the engi ne has been disturbed, refer to the previous
Distributor Removal and Installation procedure.
14. If applicable, install the alter nator upper bracket and adjust the belt
tension.
15. Connect all disconnected components at their original locations.
16. Fill the cooling system, start the engine, check for leaks and adjust the
ignition timing and carburetor idle speed and mixture.

1. Disconnect the negative battery cable.
2. Remove the air cleaner on carbureted engines.
3. If applicable, remove the ai r cleaner pre-heater shroud.
4. Disconnect the air injecti on reaction pipes, if equipped.
5. Unplug the oxygen sensor connector.
6. Label and unplug the spark plug wires.
7. Remove the spark plug wire heat shields, if equipped.
8. Remove any components which may interfere with removal.
9. Disconnect the exhaust pipe from the manifold and hang it from the
frame out of the way.
10. On some engines, it will be necessary to bend the locktabs from the bolt.
Remove the end bolts, then the center bolts. Remove the manifold.
A thin wall 6-point socket, sharpened at the leading edge and tapped onto the
head of the bolt, simplifies bending the locktabs.
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.

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.
2.5L ENGINE

1. Disconnect the negative battery cable.
2. Drain the engine block and radiator of coolant.
3. Raise and safely support the vehi cle. Remove the exhaust pipe and
lower the vehicle.
4. Remove the oil level indicator tube.
5. Remove the air cleaner.
6. Unplug the electrical and vac uum connections and disconnect the
linkage from the TBI unit.
7. Disconnect the fuel lines.
8. Remove the EGR valve.
9. Disconnect the heater hoses from the intake manifold.
10. Remove the ignition coil.

4. Use a new front oil pan gasket, cut
the tabs from the gasket. Replace the
crankshaft oil seal.
5. Place RTV sealer in the corners of the new oil pan gasket and the new
timing gear cover gasket.
6. Install the front cove r and install the oil pan-to -front cover screws and the
front cover-to-block screws. Torque scr ews to 90 inch lbs. (10 Nm).
7. Install the hub and pulle ys onto the crankshaft. Install the hub center bolt
and torque to 162 ft lbs. (220 Nm).
8. Install the drive belts and adjust.

DIGITAL EGR VALVE
The digital EGR valve, used on 3.1L (VIN T) engines, is designed to control the
flow of EGR independent of intake mani fold vacuum. The valve controls EGR
flow through 3 solenoid- opened orifices, which increa se in size, to produce 7
possible combinations. When a solenoid is energized, the armature with
attached shaft and swivel pintle, is lifted, opening the orifice.
The digital EGR valve is opened by t he ECM "quad-driver" (QDR), grounding
each solenoid circuit individually. The fl ow of EGR is regulated by the ECM
which uses information from the Coolant Temperature Sensor (CTS), Throttle
Position Sensor (TPS) and the Manifold Absolute Pressure (MAP) sensor to
determine the appropriate rate of flow for a particular engine operating
condition.

3. Apply at least 7 in. Hg of vacuum
to the damper diaphragm unit. The
door should close. If it doesn't, che ck the diaphragm linkage for binding
and correct hookup.
4. With the vacuum still applied and t he door closed, clamp the tube to trap
the vacuum. If the door doesn't remain closed, there is a leak in the
diaphragm assembly.
