CAMSHAFT TIMING BELT
Replace the camshaft timing belt every 60,000 miles. It is
recommended that the timing belt be inspected every 30,000 miles after
replacement.
CAUTION: Failure to replace a faulty camshaft timing belt may result
in serious engine damage.
The condition of camshaft drive belts should always be
checked on vehicles which have more than 50,000 miles. Although some
manufacturers do not recommend belt replacement at a specified
mileage, others require it at 60,000-100,000 miles. A camshaft drive
belt failure may cause extensive damage to internal engine components
on most engines, although some designs do not allow piston-to-valve
contact. These designs are often called "Free Wheeling".
Many manufacturers changed their maintenance and warranty

SAE J2210 specifications. If accidental system discharge
occurs, ventilate work area before resuming service.
WARNING: R-134a service equipment or vehicle A/C systems SHOULD NOT
be pressure tested or leak tested with compressed air. Some
mixtures of air/R134a have shown to be combustible at
elevated pressures. These mixtures are dangerous and may
cause fire and/or explosions. See AIR CONDITIONING SERVICE
article in GENERAL INFORMATION section.
AIR CLEANER FILTER
WARNING: Operating the engine with the air cleaner off can cause you
or others to be burned. The air cleaner not only cleans the
air, it stops flame if the engine backfires. Do not drive
with it off, and be careful working on the engine with the
air cleaner off.
ANTI-LOCK BRAKE SYSTEM
The anti-lock brake system contains electronic equipment that
can be susceptible to interference caused by improperly installed or
high output radio transmitting equipment. Since this interference
could cause the possible loss of the anti-lock braking capability,
such equipment should be installed by qualified professionals.
On models equipped with anti-lock brake systems, ALWAYS
observe the following cautions:
* DO NOT attempt to bleed hydraulic system without first
referring to the appropriate ANTI-LOCK BRAKE SYSTEM article
in the BRAKES Section.
* DO NOT mix tire sizes. As long as tires remain close to the
original diameter, increasing the width is acceptable.
Rolling diameter must be identical for all 4 tires. Some
manufacturers recommend tires of the same brand, style and
type. Failure to follow this precaution may cause inaccurate
wheel speed readings.
* Use ONLY recommended brake fluids. DO NOT use silicone brake
fluids in an ABS-equipped vehicle.
AUTOMATIC TRANSAXLE SERVICE
WARNING: Make certain that no fluid is spilled when the transaxle
fluid is inspected, or when fluid is added soon after
driving (since the engine is hot). If the fluid spills onto
the exhaust manifold, there is danger of fire.
BATTERY SERVICE
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 COMPUTER
RELEARN PROCEDURES article in GENERAL INFORMATION section.
WARNING: Batteries produce flammable hydrogen gas. Keep flames and
sparks away from the battery or and explosion may occur.
Never smoke when working in the vicinity of the battery.
WARNING: When checking or servicing the battery, disconnect the
negative cable. Be careful not to cause a short circuit by

PARASITIC LOAD EXPLANATION & TEST PROCEDURES
1998 Mitsubishi Montero
GENERAL INFORMATION
Parasitic Load Explanation & Test Procedures
* PLEASE READ THIS FIRST *
This article is provided for general information only. Not
all procedures apply to all makes and models.
GENERAL INFORMATION
The term Parasitic Load refers to electrical devices that
continue to use or draw current after the ignition switch is turned to
OFF position. This small amount of continuous battery draw is
expressed in milliamps (mA). On Ford Motor Co. and General Motors
vehicles produced after 1980, a typical Parasitic Load should be no
more than 50 milliamps (0.050 amps).
Vehicles produced since 1980 have memory devices that draw
current with ignition off for as long as 20 minutes before shutting
down the Parasitic Drain. When Parasitic Load exceeds normal
specifications, the vehicle may exhibit dead battery and no-start
condition.
Follow test procedure for checking Parasitic Loads to
completion. A brief overview of a suggested test procedure is included
along with some typical Parasitic Load specifications. Refer to the
GENERAL MOTORS PARASITIC LOAD TABLE chart.
TESTING FOR PARASITIC LOAD
INTRODUCTION
CAUTION: Always turn ignition off when connecting or disconnecting
battery cables, battery chargers or jumper cables. DO NOT
turn test switch to OFF position (which causes current to run
through ammeter or vehicle electrical system).
NOTE: Memory functions of various accessories must be reset after
the battery is reconnected.
The battery circuit must be opened to connect test switch
(shunt) and ammeter into the circuit. When a battery cable is removed,\
timer circuits within the vehicle computer are interrupted and
immediately begin to discharge. If in doubt about the condition of the
ammeter fuse, test it with an ohmmeter prior to beginning test. An
open fuse will show the same reading (00.00) as no parasitic drain.
Begin test sequence with the meter installed and on the 10-amp scale.
Select lower scale to read parasitic draw.
TEST PROCEDURE USING TEST SWITCH
1) Turn ignition off. Remove negative battery terminal cable.
Install Disconnect Tool (J-38758) test switch male end to negative
battery cable. Turn test switch knob to OFF position (current through
meter). Install negative battery cable to the female end of test
switch.
2) Turn test switch knob to ON position (current through
switch). Road test vehicle with vehicle accessories on (radio, air
conditioner, etc.). After road test, turn ignition switch to LOCKED
position and remove key. Connect ammeter terminals to test switch

1) Disconnect pressure hose from power steering pump. Attach
Pressure Gauge (MB990662-01) and Adapters (MB990993-01 and MB990994-
01). See Fig. 2. Tighten fittings to 22-29 ft. lbs. (30-39 N.m).
2) Bleed system. See HYDRAULIC SYSTEM BLEEDING under
LUBRICATION . Turn wheel several times to bleed air from gauge. Start
engine and let idle. Place thermometer in reservoir. Check fluid
level. Add fluid as necessary.
3) When fluid temperature reaches 122-140
F (50-60C),
disconnect connector from P/S pressure switch. Connect ohmmeter across
switch terminals. Slowly close shut-off valve. Check pressure when
ohmmeter indicates switch has closed (continuity). Pressure should be
218-290 (15-20 N.m). Slowly open shut-off valve. Check pressure when
ohmmeter indicates switch has opened (no continuity). Pressure should
be 102-174 (7-12 N.m). Reinstall pressure hose. Do not twist hose or
let hose interfere with adjacent parts. Replace P/S pressure switch if
pressure is not within specification. Bleed system.
CAUTION: DO NOT keep shutoff valve closed more than 3 seconds at a
time. DO NOT keep steering wheel turned to full lock
position for more than 10 seconds at a time.
STEERING WHEEL TURNING FORCE
Stationary Test
1) Position vehicle on level surface. Place steering wheel in
straight-ahead position. Start engine and let idle. Using a spring
scale, measure steering wheel turning force clockwise and
counterclockwise.
2) On Montero, turning force should be 8.2 lbs. (3.7 kg) or
less. On Montero Sport, turning force should be 8.8 lbs. (3.9 kg) or
less. If turning force exceeds specification, check for loose or
damaged belt, insufficient fluid, air in power steering fluid, and
collapsed or twisted hoses. Repair or replace as necessary.
REMOVAL & INSTALLATION
IDLER ARM
Removal
Loosen relay rod-to-idler arm lock nut. Using Steering
Linkage Puller (MB991113 or MB990635), separate idler arm from relay
rod and remove relay rod-to-idler arm lock nut. Remove idler arm bolts
and nuts. Remove idler arm. On Montero, loosen, but DO NOT remove
idler arm-to-bracket nut. Press arm from bracket and remove nut and
arm.
Inspection

idler arm support shaft. Insert bushing in idler arm. Insert idler arm
support in idler arm.
2) Install washer (knurled side toward bushing) and NEW lock\
nut. Tighten lock nut to specification. See TORQUE SPECIFICATIONS.
Place idler arm assembly in vise. Using a spring gauge, measure
turning resistance.
3) On all models, turning resistance should be 3-18 INCH lbs.
(.3-2.0 N.m). On Montero, if turning resistance is not within
specification, loosen or tighten lock nut to obtain proper resistance.
4) Install idler arm bolts and nuts. Install relay rod-to-

SYMPTOM CHECK LIST WORKSHEETS
* PLEASE READ THIS FIRST *
NOTE: This article is intended for general information purposes
only. It does not apply specifically to one make or model.
PURPOSE
Why Use the Symptom Check List Worksheets?
One of the most difficult and critical lines of communication
is between the service customer and the technician. The clearer the
technician understands the customer's concerns, the more likely the
problem will be "fixed right the first time".
The Symptom Check List Worksheets in this article are
designed to improve this communication. When used consistently, they
can be helpful in reducing shop comebacks, increasing technician
productivity, and producing satisfied customers. They also provide
other benefits:
* Reduce "No Trouble Found" problems
* Increase customer involvement
* Customer perceive that "they really care and listen"
* Save time during peak write-up periods
* Reduce recontacting customers for additional information
* Improve night drop information
* Insure all the right questions are asked at write-up
Making the Worksheets a Part of Your Normal Routine
The following information contains ideas that may be helpful
in forming habits that promote daily use of the Symptom Check Lists:
* HAVE THE SERVICE ADVISER FILL OUT THE FORM(S) WITH THE
CUSTOMER WHENEVER POSSIBLE.
* Place them in your night drop for the customer to fill out,
along with an instruction sheet to help them understand what
to do.
* Hand out the worksheets to customers while they wait in line
during the peak morning rush and ask them to fill it out. It
will save time for all concerned and improve the quality of
information received from the customer.
* Make sure it is attached to the hard copy when it goes to the
technician.
* Place a copy with the final repair papers and review it with
the customer at delivery.
* Put a new worksheet in the glovebox of all departing
customers.
* Require that you personally see a copy of all worksheets
filled out for shop comebacks.
* Hold a shop meeting to get employee buy-in and their ideas on
how to make it effective in your shop.
There are many other ways to utilize the concept, but as with
every other idea, successful implementation depends on employee
involvement and buy-in.
