CAUTIONS & WARNINGS
SUPPLEMENTAL RESTRAINT SYSTEM (SRS) AIR BAG SYSTEM
NOTE: See the AIR BAG RESTRAINT SYSTEM article in the
ACCESSORIES/SAFETY EQUIPMENT Section.
The SRS has no user-servicable parts. Always have servicing
done by an authorized dealer.
When performing maintenance on air bag equipped vehicles
always observe proper safety precautions.
WARNING: To avoid injury from accidental air bag deployment, read and
carefully follow all warnings and service precautions. See
appropriate AIR BAG RESTRAINT SYSTEM article in the
ACCESSORIES/SAFETY EQUIPMENT section.
CAUTION: Disconnect negative battery cable before servicing any air
bag system, steering column or passenger side dash
component. After any repair, turn ignition key to the ON
position from passenger's side of vehicle in case of
accidental air bag inflation
ANTI-LOCK BRAKE SYSTEM (ABS)
CAUTION: Never mix different diameter tires. On loose or uneven
surfaces, the ABS system may require longer stopping
distances than conventional brake systems. Exercise caution
when removing mud or snow from the wheels so as not to
damage the ABS wiring or speed sensors.
BATTERY WARNING
WARNING: When battery is disconnected, vehicles equipped with
computers may lose memory data. When battery power is
restored, driveability problems may exist on some vehicles.
These vehicles may require a relearn procedure. See
appropriate COMPUTER RELEARN PROCEDURES article in the
GENERAL INFORMATION section below.
REPLACING BLOWN FUSES
Before replacing a blown fuse, remove ignition key, turn off
all lights and accessories to avoid damaging the electrical system. Be
sure to use fuse with the correct indicated amperage rating. The use
of an incorrect amperage rating fuse may result in a dangerous
electrical system overload.
BRAKE PAD WEAR INDICATOR
Indicator will cause a squealing or scraping noise, warning
that brake pads need replacement.

FUEL SYSTEM PRESSURE RELEASE
WARNING: ALWAYS relieve fuel pressure before disconnecting any fuel
injection-related component. DO NOT allow fuel to contact
engine or electrical components.
1) On Colt and Mirage, remove rear seat cushion. On all
models, disconnect fuel pump harness connector at fuel tank.
2) Start engine. Let engine run until it stops. Turn ignition
off. Disconnect negative battery terminal. Connect fuel pump harness
connector.
FUEL PUMP
Removal & Installation
1) Fuel pump assembly is located inside fuel tank. Release
fuel pressure from system. See FUEL SYSTEM PRESSURE RELEASE. Raise
vehicle on hoist. Drain fuel into suitable container. Disconnect
electrical connectors and fuel hoses at fuel tank.
2) Remove fuel filler hose from fuel tank. Remove nuts
securing fuel tank. Remove fuel tank from vehicle and remove fuel pump
assembly. To install, reverse removal procedure. Tighten nuts to
specification. See TORQUE SPECIFICATION table.
FUEL RAILS & INJECTORS (PFI)
Use a rag to cover fuel hose connection before disconnecting
high pressure fuel hose at fuel rail. Some residual fuel pressure may
still be in system.
Removal (Except Pickup & Ram-50 2.4L)
1) On all models, relieve fuel pressure. See
FUEL SYSTEM PRESSURE RELEASE . Disconnect negative battery cable. On
Montero, Pickup, Ram-50, Stealth and 3000GT 3.0L, disconnect air
intake plenum. On Eclipse, disconnect PCV valve hose.
2) On Colt Vista, disconnect coolant temperature sensor
connector, idle speed control servo connector and brake booster vacuum
hose. On all models, disconnect high pressure fuel hose at fuel rail.
3) Disconnect fuel return hose. Disconnect vacuum hoses. On
Eclipse, Colt and Colt 200, disconnect throttle cable clamp. Remove
center cover. On all models, disconnect injector electrical
connectors. Remove fuel rail bolts and lift fuel rail and injectors
from engine.
Installation
To install, reverse removal procedure. Tighten bolts to
specifications. See TORQUE SPECIFICATIONS table.
Removal (Pickup & Ram-50 2.4L)
1) Relieve fuel pressure. See FUEL SYSTEM PRESSURE RELEASE.
Disconnect negative battery cable. Drain coolant. On all models,
disconnect air intake hose. Disconnect breather hose (if applicable)
and vacuum hoses.
2) Disconnect coolant lines as necessary for clearance.
Disconnect injector electrical connectors. Position all lines, hoses
and electrical connectors out of way. Disconnect throttle and/or
kickdown cables. Remove throttle body assembly and position it out of
the way.
3) Disconnect high pressure fuel hose at fuel rail.
Disconnect fuel return line and vacuum line connection at fuel rail.
Remove fuel rail bolts and lift fuel rail and injectors from engine.

fluid to bring level to lower mark of dipstick if necessary. Recheck
fluid level after transmission is at normal operating temperature.
TRANSFER CASE
Drain plug is located on bottom of transfer case. Change
drain plug gasket whenever fluid is changed. On 3000GT, lubricant
level should be approximately .5" (13 mm) below fill hole on side of
transfer case. On all others models, lubricant level should be to
bottom of fill hole on side of transfer case.
HYDRAULIC CONTROL PRESSURE ADJUSTMENTS
LINE PRESSURE CHECK (EXCEPT MONTERO & PICKUP)
1) Set parking brake. Place shift lever in Neutral position.
Attach engine tachometer. Remove line pressure port plug located above
front transaxle shaft, forward of governor pressure port plug. On
Precis, line pressure port is located below bell housing, at front of
transaxle oil pan. Using appropriate adapter, attach pressure gauge.
2) Start engine, and bring to operating temperature. With
gear selector in Drive position, bring engine speed to 2500 RPM. Pull
throttle control cable (if equipped) wide open at transaxle side.
3) Line pressure should be 98-100 psi (6.9-7.0 kg/cm
) on
Mirage, or 124-127 psi (8.7-8.9 kg/cm) on all others. If line
pressure is not to specification, proceed to LINE PRESSURE ADJUSTMENT.
LINE PRESSURE ADJUSTMENT (EXCEPT MONTERO & PICKUP)
1) Drain transaxle fluid. Remove oil pan. Disconnect throttle
control cable from throttle cam. Remove oil temperature sensor (if
equipped). Disconnect solenoid connector. On some models, it may be
necessary to push solenoid wire harness connector and grommet into
transaxle case.
2) Remove oil filter screen and plate. Noting location and
length of bolts, remove valve body. DO NOT drop internal parts. Adjust
line pressure by turning regulator valve adjusting screw.
3) Turn adjusting screw counterclockwise to increase pressure
or clockwise to decrease pressure. One complete turn of adjusting
screw changes line pressure as follows.
* 3.7 psi (.26 kg/cm
) on Mirage with F3A21 Transaxle
* 5.4 psi (.39 kg/cm) on Precis
* 54 psi (3.8 kg/cm) on all others
4) After adjustment, reverse removal procedure to install.
Refill transaxle.
LINE PRESSURE (MONTERO)
1) Remove plug from line pressure take-off port located
behind transmission shift control lever. Install Hydraulic Pressure
Meter (MD998330) with Adapter (MD998206).
2) Place vehicle on dynamometer. Apply parking brake and
start engine. With brake applied, place transmission in Drive. Note
pressure at idle. Pressure should be 74-85 psi (5.2-6.0 kg/cm
).
3) Raise engine RPM to stall speed (2100-2400 RPM). Note lin\
e
pressure. Pressure should be 156-185 psi (11.0-13.0 kg/cm
).
4) Shift transmission into Reverse with brake applied. At
idle, pressure should be 112-130 psi (7.9-9.1 kg/cm
). Raise engine
RPM to stall speed (2100-2400 RPM). Note line pressure. Pressure
should be 227-285 psi (16.0-20.0 kg/cm
). If readings are not to
