The MOPAR Silicone Rubber Adhesive Sealant
gasket material or equivalent should be applied in a
continuous bead approximately 3mm (0.120 inch) in
diameter. All mounting holes must be circled. For
corner sealing, a 3.17 or 6.35 mm (1/8 or 1/4 inch.)
drop is placed in the center of the gasket contact
area. Uncured sealant may be removed with a shop
towels. Components should be torqued in place while
the sealant is still wet to the touch (within 10 min-
utes). The usage of a locating dowel is recommended
during assembly to prevent smearing of material off
location.
CRANKSHAFT SPROCKET BOLT ACCESS PLUG
An Access plug is located in the right inner fender
shield. Remove the plug and insert proper size
socket, extension and rachet, when crankshaft rota-
tion is necessary.
ENGINE PERFORMANCE
If a loss of performance is noticed, ignition timing
should be checked. If ignition timing is retarded by
9, 18 or 27É indicating 1, 2 or 3 (timing belt or chain)
teeth may have skipped, then, camshaft and acces-
sory shaft timing with the crankshaft should be
checked. Refer to Engine Timing Sprockets and Oil
Seals of the Engine Section. To provide best vehicle performance and lowest ve-
hicle emissions, it is most important that the tune-up
be done accurately. Use the specifications listed on
the Vehicle Emission Control Information label
found in the engine compartment. (1) Test cranking amperage draw. See Starting
Motor Cranking Amperage Draw Electrical Section
of this manual. (2) Tighten the intake manifold bolts to specifica-
tions. (3) Perform cylinder compression test.(a) Check engine oil level and add oil if neces-
sary. (b) Drive the vehicle until engine reaches normal
operating temperature. (c) Select a route free from traffic and other
forms of congestion, observe all traffic laws, and ac-
celerate through the gears several times briskly.
CAUTION: Do not overspeed the engine. The higher
engine speed may help clean out valve seat deposits
which can prevent accurate compression readings.
(d) Remove all spark plugs from engine. As
spark plugs are being removed, check electrodes for
abnormal firing indicators fouled, hot, oily, etc.
Record cylinder number of spark plug for future
reference. (e) Disconnect coil wire from distributor and se-
cure to good ground to prevent a spark from start- ing a fire (Conventional Ignition System). For Direct
Ignition System DIS disconnect the coil connector. (f) Be sure throttle blade is fully open during the
compression check. (g) Insert compression gage adaptor into the #1
spark plug hole in cylinder head. Crank engine until
maximum pressure is reached on gage. Record this
pressure as #1 cylinder pressure. (h) Repeat Step G for all remaining cylinders.
(i) Compression should not be less than (689kPa)
100 psi and not vary more than 25 percent from
cylinder to cylinder. (j) If one or more cylinders have abnormally low
compression pressures, repeat steps 3b through 3h. (k) If the same cylinder or cylinders repeat an
abnormally low reading on the second compression
test, it could indicate the existence of a problem in
the cylinder in question.
The recommended compression pressures are
to be used only as a guide to diagnosing engine
problems. An engine should not be disassembled
to determine the cause of low compression un-
less some malfunction is present. (4) Clean or replace spark plugs as necessary and
adjust gap as specified in Electrical Group 8. Tighten to
specifications. (5) Test resistance of spark plug cables. Refer to
Ignition System Secondary Circuit Inspection Electri-
cal Section Group 8. (6) Inspect the primary wire. Test coil output volt-
age, primary and secondary resistance. Replace parts
as necessary. Refer to Ignition System and make nec-
essary adjustment. (7) Ignition timing should be set to specifications.
(See Specification Label in engine compartment). (8) Test fuel pump for pressure and vacuum. Refer to
Fuel System Group 14, Specifications. (9) The air filter elements should be replaced as
specified in Lubrication and Maintenance, Group 0. (10) Inspect crankcase ventilation system as out
lined in Lubrication and Maintenance, Group 0. For
emission controls see Emission Controls Group 25 for
service procedures. (11) Inspect and adjust accessory belt drives refer-
ring to Accessory Belt Drive in Cooling System, Group
7 for proper adjustments. (12) Road test vehicle as a final test.
HONING CYLINDER BORES
Before honing, stuff plenty of clean shop towels
under the bores, over the crankshaft to keep abrasive
materials from entering crankcase area. (1) Used carefully, the cylinder bore resizing hone
C-823 equipped with 220 grit stones, is the best tool for
this job. In addition to deglazing, it will reduce taper
and out-of-round as well as removing light

CAUTION: Be sure that the tapped holes maintain
the original centerline.
Heli-Coil tools and inserts are readily available
from automotive parts jobbers.
HYDROSTATIC LOCKED ENGINE
When an engine is suspected to be hydrostaticly
locked, regardless of what caused the problem, these
steps should be used.
CAUTION: Do Not Use Starter Motor To Rotate En-
gine, severe damage may occur.
(1) Inspect air cleaner, induction system and in-
take manifold to insure system is dry and clear of
foreign material. (2) Remove negative battery cable.
(3) Place a shop towel around the spark plugs
when removing them from the engine. This will
catch any fluid that may possibly be in the cylinder
under pressure. (4) With all spark plugs removed, rotate engine
crankshaft using a breaker bar and socket. (5) Identify the fluid in the cylinder(s) (i.e., cool-
ant, fuel, oil or other). (6) Make sure all fluid has been removed from the
cylinders. Inspect engine for damage (i.e., Connecting
Rods, Pistons, Valves etc.) (7) Repair engine or components as necessary to
prevent this problem from occurring again.
CAUTION: Squirt approximately 1 teaspoon of oil
into cylinders, rotate engine to lubricate the cylin-
der walls to prevent damage on restart.
(8) Install new spark plugs.
(9) Drain engine oil and remove oil filter.
(10) Fill engine with specified amount of approved
oil and install new oil filter. (11) Connect negative battery cable.
(12) Start engine and check for any leaks.

GENERAL INFORMATION
ENGINE IDENTIFICATION NUMBER OR CODE
The engine identification number is located on the
rear of the cylinder block just below the cylinder
head (Fig. 1). METHANOL FUEL COMPATIBILITY IDEN-
TIFICATION Beginning this model year, Chrysler began produc-
ing AA-Body vehicles designed to operate on a mix-
ture of gasoline and methanol. These automobiles are
referred to as Flexible Fuel vehicles.
2.2/2.5L ENGINE SPECIFICATION
9 - 8 2.2/2.5L ENGINE Ä

Flexible fuel vehicles can operate on a mixture of
up to 85 percent methanol, 15 percent unleaded gas-
oline. These vehicles also operate on mixtures con-
taining a lower percentage of methanol or just pure
unleaded gasoline. Engine components which are required for safe op-
eration using fuel containing methanol alcohol are
identified by a standard green color and/or display
the statement methanol compatible imprinted on the
component. To ensure continued safe operation, these
components must be serviced only with genuine MO-
PAR replacement parts. Methanol compatible parts for the 2.5L FFV (Flex-
ible Fuel Vehicle) engine include, but are not limited
to; the valve stem oil seals, all piston rings, the oil
fill cap, the fuel injectors, fuel rail, fuel pressure reg-
ulator, hoses and the vacuum control harness hose. BLOCK: All four cylinder cast iron blocks have
cast-in recesses in the bottom of each cylinder bore to
provide connecting rod clearance; especially needed
for 2.5L engines. The bores are also siamese to min-
imize engine length. A coolant passage is drilled
cross-ways through the siamese section to enhance
between the bore cooling on some engine types. A
partial open deck is used for cooling and weight re-
duction with oil filter, water pump, and distributor
mounting bosses molded into the front (radiator side)
of the block. Nominal wall thickness is 4.5 mm. Five
main bearing bulkheads and a block skirt extending
3 mm below the crankshaft center line add to the
blocks high rigidity with light weight. CRANKSHAFT: A nodular cast iron crankshaft is
used in TBI engines. A forged steel crankshaft is
used in the Turbo III engine. All engines have 5 main bearings, with number 3 flanged to control
thrust. The 60 mm diameter main and 50 mm diam-
eter crank pin journals (all) have undercut radiuses
fillets that are deep rolled for added strength. To op-
timize bearing loading 4 counterweights are used.
Hydrodynamic seals (installed in diecast aluminum
retainers) provide end sealing, where the crankshaft
exits the block. Anaerobic gasket material is used for
retainer-to-block sealing. No vibration damper is
used. A sintered iron (TBI engine and steel billet
Turbo III engines) timing belt sprocket is mounted
on the crankshaft nose. This sprocket provides mo-
tive power; via timing belt to the camshaft and inter-
mediate shaft sprockets (also sintered iron (TBI
engine and steel billet Turbo III engines) providing
timed valve, distributor, and oil pump actuation. PISTONS: Some Chrysler pistons have cast-in
steel struts at the pin bosses for autothermic control.
All 2.2L and 2.5L piston tops have cuts to provide
valve clearance. Some pistons are dished to provide
various compression ratios. Standard 2.2L and 2.5L
engines are designed for 9.5:1 and 8.9:1 compression
ratios respectively. The 2.5L piston is dished and is a
lightweight design to enhance engine smoothness.
The 2.2L turbo III uses dished pistons providing a
8.3:1 compression ratio. All standard 2.2/2.5L and
2.5L FFV engines use pressed-in piston pins to at-
tach forged steel connecting rods, 2.2L turbo III en-
gine uses a full floating piston pin and connecting
rod assembly. PISTONS RINGS: The 2.2/2.5L engines share
common piston rings throughout, including molybde-
num filled top ring for reliable compression sealing
and a tapered faced intermediate ring for additional
cylinder pressure control. The 2.5L FFV engine fea-
ture all chrome rings for enhanced long term dura-
bility under multi-fueled conditions. CYLINDER HEAD: The cylinder head is cast alu-
minum with in-line valves. The 2.2/2.5L and 2.5L
FFV valves are arranged with alternating exhaust
and intake. The intake and exhaust ports are located
in the rearward, facing side of the head. The Turbo
III valves are arranged in two inline banks, with the
ports of the bank of two intake valves per cylinder
facing toward the radiator side of engine and ports of
the bank of two exhaust valve per cylinder facing to-
ward the dash panel. The intake ports feed fast-burn
design combustion chambers (2.2/2.5L and 2.5L FFV
only) with the spark plug located close to the center
line of the combustion chamber for optimum effi-
ciency. An integral oil gallery within the cylinder
head supplies oil to the hydraulic lash adjusters,
camshaft, and valve mechanisms. CAMSHAFT: The nodular iron camshaft has five
bearing journals (2.2/2.5L and 2.5L FFV). The Turbo
III employs dual camshafts that have nine bearing
journals. Flanges at the rear journal control cam-
