Rigid Case (Direct Reading)
# See Figure 29
A rigid case or direct reading torque wrench is
equipped with a dial indicator to show torque values.
One advantage of these wrenches is that they can be
held at any position on the wrench without affecting
accuracy. These wrenches are often preferred be-
cause they tend to be compact, easy to read and have
a great degree of accuracy.

Because the frictional characteristics of each fas-
tener or threaded hole will vary, clamp loads which
are based strictly on torque will vary as well. In most
applications, this variance IS not significant enough
to cause worry. But, in certain applications, a manu-

torque angle method of installation would be speci-
fied. When installing fasteners which are torque angle

any compliance from the joint. The fastener is then

Throughout this manual, specifications are given to
help you determine the condition of various compo-
nents on your vehicle, or to assist you in their installa-
tion. Some of the most common measurements in-
clude length (in. or cm/mm), torque (ft. Ibs., inch Ibs.
or Nm) and pressure (psi, in. Hg, kPa or mm Hg). In
most cases, we strive to provide the proper measure-
ment as determined by the manufacturers engineers.
Though, in some cases, that value may not be con-
veniently measured with what is available in your
toolbox. Luckily, many of the measuring devices

The Vehicle Identification Number (VIN) is located
on a plate which is attached to the left top side of the
instrument panel. These numbers are visible from the
outside of the vehicle. All Vehicle Identification Num-
bers contain 17 digits. The vehicle number is a code
which tells country, make, vehicle type, engine, body
and many other important characteristics of that spe-
cific vehicle.
There is also a vehicle information code plate
which is riveted to the bulkhead in the engine com-
partment. The plate shows the VIN, model code, en-
gine model, transaxle model and body color codes.
The engine code used on this plate differs from the
code letter used in the 8th position of the Vehicle
Identification Number (VIN). Either code can be used
to identify the particular engine in the vehicle. Since
the vehicle owners card is usually carried, it may be if the engine is equipped with a turbocharger. If the
8th VIN number is a U, there is no doubt that the en-
gine in question is a 2.OL DOHC engine equipped
with a turbocharger.
The engine codes found on the vehicle information
code plate are as follows:
l 4G15--1.5L SOHC engine l 4G61-1.6L DOHC engine l 4G93-1.8L SOHC engine l 4G63-2.OL (SOHC or DOHC) engine l 4G64-2.4L (SOHC or DOHC) engine l 6G72-3.OL (SOHC or DOHC) engine l 6G74-3.5L DOHC engine
A vehicle safety certification label is attached to
the face of the left door pillar post. This label indi-
cates the month and year of manufacture, Gross Ve-
hicle Weight Rating (GRVW) front and rear, and Ve-
hicle Identification Number (VIM). 4 character code as on the vehicle information code
plate is used. The engine serial number is also
stamped near the engine model number. As men-
tioned above, the engine can also be identified by the
8th digit in the VIN number.
The transaxle model code is located on the vehicle
information code plate. The transaxle identification
number is etched on a boss located on the front up-
per portion of the case.
The code for the drive axle is etched on a boss lo-
cated on the case of the differential carrier.
easier to use the code letter in the VIN for engine ref-

engine identification is that code 4663, located on

Used fluids such as engine oil, transaxle fluid, an-
tifreeze and brake fluid are hazardous wastes and
must be disposed of properly. Before draining any
fluids, consult with your local authorities; in many ar-
eas, waste oil, antifreeze, etc. is being accepted as a
part of recycling programs. A number of service sta-
tions and auto parts stores are also accepting waste
fluids for recycling.
Be sure of the recycling center’s policies before
draining any fluids, as many will not accept different
fluids that have been mixed together.
ENGINE OIL
6 See Figure 148
WMitsubishi recommends that SAE 5W-30
viscosity engine oil should be used for all clia
mate conditions, however, SAE low-30 is ac
ceptable for vehicles operated in moderate-
to-hot climates. the SAE number, the lighter the oil; the lower the vis-
cosity, the easier it is to crank the engine in cold
weather but the less the oil will lubricate and protect
the engine in high temperatures. This number is
marked on every oil container.
Oil viscosity’s should be chosen from those oils
recommended for the lowest anticipated temperatures
during the oil change interval. Due to the need for an
oil that embodies both good lubrication at high tem-
peratures and easy cranking in cold weather, multi-
grade oils have been developed. Basically, a multi-
grade oil is thinner at low temperatures and thicker at
high temperatures. For example, a low-40 oil (the W
stands for winter) exhibits the characteristics of a 10
weight (SAE 10) oil when the car is first started and
the oil is cold. Its lighter weight allows it to travel to
the lubricating surfaces quicker and offer less resis-
tance to starter motor cranking than, say, a straight
30 weight (SAE 30) oil. But atier the ensine reaches
operating temperature, the low-40 oil begins acting
like straight 40 weight (SAE 40) oil, its heavier weight
providing greater lubrication with less chance of
foaming than a straight 30 weight oil. Synthetic oil is not for every car and every type of
driving, so you should consider your engine’s condi-
tion and your type of driving. Also, check your car’s
warranty conditions regarding the use of synthetic oils.
FUEL
All models equipped with a SOHC (Single Over-
head Camshaft) engine are designed to operate using
regular unleaded fuel with a minimum of 87 octane.
All models equipped with a DOHC (Dual Overhead
Camshaft) engine are designed to operate using reg-
ular unleaded fuel with a minimum of 91 octane. Mit-
subishi warns that using gasoline with a lower octane
rating can cause persistent and heavy knocking, and
may cause internal engine damage.
If your vehicle is having problems with rough idle
or hesitation when the enoine is cold, it mav be
caused by low volatility fuel. If this occurs, iry a dif-
ferent grade or brand of fuel.

Synthetic Oil
There are many excellent synthetic and fuel-effi-
cient oils currently available that can provide better
gas mileage, longer service life and, in some cases,
better engine protection. These benefits do not come
without a few hitches, however; the main one being
the price of synthetic oil, which is significantly more
expensive than conventional oil.

retaining bolt holding the exhaust pipe to the bottom
of the exhaust manifold. Separate the pipe from the
manifold and remove the gasket.
19. Remove the bolts holding the support brace
to the bottom of the intake manifold.
20. Use the special hex wrench (MB 998051-01)
and loosen the head bolts in the order shown in 2 or
3 passes. When all are finger loose, remove the bolts.
21. Rock the head gently to break it loose; if tap-
ping is necessary, do so with a rubber or wooden
mallet at the corners of the head. DO NOT pry the
head up by wedging tools between the head and the
block.
22. Lift the head free of the engine. It is coming
off with both manifolds and the intake plenum at-
tached; the help of an assistant is recommended for
lifting. Support the head assembly on wooden blocks
on a suitable workbench. Refer to Cleaning and In-
spection in this section for work to be done before in-
stalling the head. If the head has been removed for
work other than gasket replacement, the rocker as-
sembly and camshaft or other components may be
removed.
Before reinstallation, the head should be com-
pletely assembled on the bench. This allows proper
location and tightening of all the external items.
To install: 23. Place a new gasket on the engine so that the
identifying mark faces up (towards the head) and is at
the timing belt end of the block. Install a new gasket
on the exhaust pipe.
Do not apply sealant to the head gasket or
mating surfaces.
24. Install the head straight down onto the block.
Try to eliminate most of the side-to-side adjust-
ments as this may move the gasket out of position.
Install the bolts by hand and just start each bolt 1 or
2 turns on the threads.
25. The head bolt torque specification is 68 ft.
Ibs. (92 Nm) for a cold engine. The bolts must be
tightened in the order shown in 3 steps. On the first
pass, tighten all the bolts to about 22 ft. Ibs. (30 Nm),
then proceed through the order tightening each bolt
to about 45 ft. Ibs. (61 Nm). The final torque is
achieved on the third pass.
26. Install the intake manifold support brace to
the manifold and tighten the bolts to 16 ft. Ibs. (22
Nm). 27. Making sure the gasket is still in place, con-

*The 1.6L engine is not equipped with
silent shafts. Disregard all instructions per-
taining to silent shafts if working on that en-
gine.
1. Disconnect the negative battery cable.
2. Remove the engine undercover.
3. If necessary, remove the coolant reservoir.
4. Using the proper equipment, slightly raise
the engine to take the weight off the side engine
mount. Remove the engine mount bracket.
5. Remove the drive belts, tension pulley brack-
ets, water pump pulley and crankshaft pulley.
6. Remove all attaching screws and remove the
upper and lower timing belt covers.
7. Rotate the crankshaft clockwise and align the
timing marks so No. 1 piston will be at TDC of the
compression stroke. At this time the timing marks on
the camshaft sprocket and the upper surface of the
cylinder head should coincide, and the dowel pin of
the camshaft sprocket should be at the upper side.
*Always rotate the crankshaft in a clockwise
direction. Make a mark on the back of the
timing belt indicating the direction of rotation
so it may be reassembled in the same direc-
tion if it is to be reused.
8. Remove the auto tensioner and remove the
outermost timing belt.
9. Remove the timing belt tensioner pulley, ten-
sioner arm, idler pulley, oil pump sprocket, special
washer, flange and spacer.
10. Remove the silent shaft (inner) belt tensioner
and remove the belt.
To install: 11. Align the timing marks on the crankshaft
sprocket and the silent shaft sprocket. Fit the inner
timing belt over the crankshaft and silent shaft
sprocket. Ensure that there is no slack in the belt.
12. While holding the inner timing belt tensioner
with your fingers, adjust the timing belt tension by
applying a force towards the center of the belt, until
the tension side of the belt is taut. Tighten the ten-
sioner bolt.
*When tightening the bolt of the tensioner,
ensure that the tensioner pulley shaft does
not rotate with the bolt. Allowing it to rotate
with the bolt can cause excessive tension on
the belt.
13. Check belt for proper tension by depressing
the belt on it’s long side with your finger and noting
the belt deflection. The desired reading is 0.20-0.28
in. (5-7mm). If tension is not correct, readjust and
check belt deflection.
14. Install the flange, crankshaft and washer to
the crankshaft. The flange on the crankshaft sprocket
must be installed towards the inner trming belt
sprocket. Tighten bolt to 80-94 ft. Ibs. (110-130
Nm).
15. To install the oil pump sprocket, insert a
Phillips screwdriver with a shaft 0.31 in. (8mm) in di-
ameter into the plug hole in the left side of the cylin-
der block to hold the left silent shaft. Tighten the nut
to 36-43 ft. Ibs. (50-60 Nm).
16. Using a wrench, hold the camshaft at it’s
hexagon between journal No. 2 and 3, then tighten
the bolt to 58-72 ft. Ibs. (80-100 Nm). If no hexagon
is present between journal No. 2 and 3, hold the
sprocket stationary with a spanner wrench while
tightening the retainer bolt.
17. Carefully push the auto tensioner rod in until
the set hole in the rod aligns with the hole in the
cylinder. Place a wire into the hole to retain the rod.
18. Install the tensioner pulley onto the tensioner
arm. Locate the pinhole in the tensioner pulley shaft
to the left of the center bolt. Then, tighten the center
bolt finger-tight.
19. When installing the timing belt, turn the 2
camshaft sprockets so their dowel pins are located on
top. Align the timing marks facing each other with the
top surface of the cylinder head. When you let go of
the exhaust camshaft sprocket, it will rotate 1 tooth in
the counterclockwise direction. This should be taken
into account when installing the timing belts on the
sprocket.
*Both camshaft sprockets are used for the
intake and exhaust camshafts and are pro-
vided with 2 timing marks. When the
sprocket is mounted on the exhaust
camshaft, use the timing mark on the right
with the dowel pin hole on top. For the intake
camshafl sprocket, use the 1 on the left with
the dowel pin hole on top.
20. Align the crankshaft sprocket and oil pump
sprocket timing marks.
21. After alignment of the oil pump sprocket tim-
ing marks, remove the plug on the cylinder block and
insert a Phillips screwdriver with a shaft diameter of
0.31 in. (8mm) through the hole. If the shaft can be
inserted 2.4 in. deep, the silent shaft is in the correct
position. If the shaft of the tool can only be inserted
0.61 .O in. (2C-25mm) deep, turn the oil pump
sprocket 1 turn and realign the marks. Reinsert the
tool making sure it is inserted 2.4 in. deep. Keep the
tool inserted in hole for the remainder of this proce-
dure.
*The above step assures that the oil pump
socket is in correct orientation to the silent
shafts. This step must not be skipped or a vi-
bration may develop during engine opera-
tion.
22. Install the timing belt as follows:
a. Install the timing belt around the intake
camshaft sprocket and retain it with 2 spring
clips or binder clips.
b. Install the timing belt around the exhaust
sprocket, aligning the timing marks with the
cylinder head top surface using 2 wrenches. Re-
tain the belt with 2 spring clips. c. Install the timing belt around the idler pul-
ley, oil pump sprocket, crankshaft sprocket and
the tensioner pulley. Remove the 2 spring clips.
d. Lift upward on the tensioner pulley in a
clockwise direction and tighten the center bolt.
Make sure all timing marks are aligned.
e. Rotate the crankshaft ‘14 turn counterclock-
wise. Then, turn in clockwise until the timing
marks are alrgned again.
23. To adjust the timing (outer) belt, turn the
crankshaft ‘14 turn counterclockwise, then turn it
clockwise to move No. 1 cylinder to TDC.
24. Loosen the center bolt. Using tool
MD998738 or equivalent and a torque wrench, apply
a torque of 22-25 inch. Ibs. (2.6-2.8 Nm). Tighten
the center bolt.
25. Screw the special tool into the engine left
support bracket until its end makes contact with the
tensioner arm. At this point, screw the special tool in
some more and remove the set wire attached to the
auto tensioner, if the wire was not previously re-
moved. Then remove the specral tool.
26. Rotate the crankshaft 2 complete turns clock-
wise and let it sit for approximately 15 minutes. Then,
measure the auto tensioner protrusion (the distance
between the tensioner arm and auto tensioner body)
to ensure that it is within 0.15-0.18 in. (3.8-4.5mm).
If out of specification, repeat Step l-4 until the spec-
ified value is obtained.
27. If the timing belt tension adjustment is being
performed with the engine mounted in the vehicle,
and clearance between the tensioner arm and the auto
tensioner body cannot be measured, the following al-
ternative method can be used:
a. Screw in special tool MD998738 or equiv-
alent, until its end makes contact with the ten-
sioner arm.
b. After the special tool makes contact with
the arm, screw it in some more to retract the auto
tensioner pushrod while counting the number of
turns the tool makes until the tensioner arm is
brought into contact with the auto tensioner
body. Make sure the number of turns the special
tool makes conforms with the standard value of
21/a-3 turns.
c. Install the rubber plug to the timing belt
rear cover.
28. Install the timing belt covers and all related
items.
29. Connect the negative battery cable.
