1998 MITSUBISHI MONTERO tire pressure

Other Means Of Identification
Refrigerant R-134a, when viewed through a sight glass, may
have a "milky" appearance due to the mixture of refrigerant and
lubricating oil. As the refrigerant and oil DO NOT exhibit a "clear"
sight glass on a properly charged A/C system, most R-134a systems have
no sight glass.
REFRIGERANT OILS
NOTE: Use ONLY the specified oil for the appropriate system or A/C
compressor. Always check vehicle underhood A/C specification
label or A/C compressor label before adding refrigerant oil
to A/C compressor/system. See Figs. 2 and 3. Always use
refrigerant oil specified on vehicle underhood A/C
specification label if different from the following list.
Refrigerant R-12 based systems use mineral oil, while R-134a
systems use Polyalkylene Glycol (PAG) oils. Using a mineral oil based
lubricant with R-134a will result in A/C compressor failure due to
lack of proper lubrication. The following R-134a refrigerant oils are
currently specified:
Use DENSO/ND-Oil 8 refrigerant oil on Nippondenso
compressors. Use SUN PAG 56 refrigerant oil on Sanden compressors.
NOTE: PAG oils absorb moisture very rapidly, 2.3-5.6 percent by
weight, as compared to a mineral oil absorption rate of
0.005 percent by weight.
SERVICE EQUIPMENT
A/C systems using R-134a refrigerant and PAG lubricants
cannot use R-12 refrigerant or mineral oil lubricants. R-134a
refrigerant is NOT compatible or interchangeable with R-12
refrigerant. Separate sets of hoses, manifold gauge sets and
recovery/recycling equipment are required to service the different
systems. This is necessary to avoid cross-contaminating and damaging
A/C system. A single set of A/C service equipment cannot be cleaned
thoroughly enough to be used with both types of refrigerant.
All equipment used to service A/C systems using R-134a must
be U.L. listed and certified to meet SAE standard J2210. The service
hoses on the manifold gauge set must have manual (turn wheel) or
automatic back-flow valves at the service port connector ends. This
will prevent refrigerant from being released into the atmosphere.
For identification purposes, R-134a service hoses must have a
Black stripe along its length and be clearly labeled SAE J2196/R-134a.
The low pressure test hose is Blue with a Black stripe. The high
pressure test hose is Red with a Black stripe, and the center test
hose is Yellow with a Black stripe.
R-134a manifold gauge sets can be identified by one or all of
the following: Labeled FOR USE WITH R-134a on set, labeled HFC-134a or
R-134a on gauge face, or by a Light Blue color on gauge face. In
addition, pressure/temperature scales on R-134a gauge sets are
different from R-12 manifold gauge sets.
SYSTEM SERVICE VALVES
SCHRADER-TYPE VALVES
NOTE: Although similar in construction and operation to a tire
valve, NEVER replace a Schrader-type valve with a tire valve.

Schrader valve is similar in construction and operation to a
tire valve. When a test gauge hose with built-in valve core depressor
is attached, Schrader stem is pushed inward to the open position and
allows system pressure to reach gauge.
If test hose does not have a built-in core depressor, an
adapter must be used. Never attach hose or adapter to Schrader valve
unless it is first connected to manifold gauge set.
Refrigerant R-12 Schrader-type valve cores have TV5 thread
size. Refrigerant R-134a Schrader-type valve cores use M6 (Metric)
threads. See Fig. 1.

REFRIGERANT RECOVERY/RECYCLING
Refrigerant recovery/recycling equipment is used to remove
refrigerant from vehicle's A/C system without polluting atmosphere. To
remove and recycle refrigerant, connect the recovery/recycling
equipment and following the equipment manufacturer's instructions.
Removed refrigerant is filtered, dried and stored in a tank
within the recovery/recycling equipment until it is ready to be pumped
back into vehicle A/C system. With refrigerant stored in the
recovery/recycling equipment, A/C system can be opened without
polluting atmosphere.
NOTE: Separate sets of hoses, gauges and refrigerant
recovery/recycling equipment MUST be used for R-12 and
R-134a based systems. DO NOT mix R-12 and R-134a
refrigerants, as their refrigerant oils and desiccants are
not compatible. It is NOT possible to clean equipment
thoroughly enough to prevent cross-contamination of A/C
systems. On systems with R-134a refrigerant, use
Polyalkylene Glycol (PAG) wax-free refrigerant oil.

3) Tighten lock nut, and ensure brake pedal height is within
specification. Start engine to evacuate brake booster chamber. Stop
engine, and apply brake several times to remove vacuum from brake
booster.
4) Using hand pressure, depress brake pedal to measure free
play before resistance is felt. Free play distance for all models is
0.10-0.31" (3-8 mm). If distance is not within specification, it is
probably caused by excessive play between the brake pedal arm and the
clevis pin. Check and replace as necessary.
5) Start engine and apply 110 lbs. (490 N) of pressure to
brake pedal. With the carpet pulled back, measure the distance between
the brake pedal and the floorboard. If the distance is not 3.1-3.5"
(80-90 mm) check for air in brake hydraulic system, brake adjustment
or defective parking brake component or adjustment. Adjust or repair
as necessary.
LOAD-SENSING PROPORTIONING VALVE (LSPV)
Montero
1) Park vehicle on level surface. Remove excess weight from
vehicle. Make sure the lever is all the way towards the valve side.
Measure length of entire spring. See Fig. 1.
If spring length is not within specification, adjust spring
support until correct length is obtained. See LSPV SPRING LENGTH
table.

NOTE: Speedometer circuit test for Montero and 3000GT is not
available from manufacturer at time of publication.
Circuit Test (Eclipse, Galant & Mirage)
1) Remove instrument cluster. See INSTRUMENT CLUSTER under
REMOVAL & INSTALLATION. Disconnect instrument cluster harness
connector. Turn ignition on. Connect voltmeter between ground and
instrument cluster harness-side connector terminal No. 36
(Yellow/White wire) on Eclipse, terminal No. 49 (Yellow/White wire) \
on
Galant, or terminal No. 51 (Yellow wire) on Mirage. Move vehicle
forward and backward. If voltmeter reads 4.5 volts or greater, go to
step 4). If voltage reading is not as specified, replace speedometer
assembly.
2) Connect voltmeter between ground and instrument cluster
harness-side connector terminal No. 10 (Black/White wire) on Eclipse,
terminal No. 24 (Black/White wire) on Galant, or terminal No. 42
(Black/White wire) on Mirage. Turn ignition on. Move vehicle forward
and backward. If battery voltage is present, replace speedometer
assembly. If battery voltage is not present, go to step 4).
3) On Mirage, check continuity between ground and instrument
cluster harness-side connector terminal No. 11 (Black wire). If
continuity is present, go to next step. If continuity is not present,
check circuit between ground and instrument cluster. See
WIRING DIAGRAMS . Repair as necessary.
4) Check vehicle speed sensor. See VEHICLE SPEED SENSOR under
COMPONENT TESTS. Replace as necessary. If sensor is okay, check
harness connectors to instrument cluster. Repair as necessary. If
connectors are okay, check circuit between power supply and instrument
cluster. See WIRING DIAGRAMS . Repair as necessary.
Circuit Test (Montero Sport)
1) Disconnect vehicle speed sensor harness connector. Check
vehicle speed sensor. See VEHICLE SPEED SENSOR under COMPONENT TESTS.
Replace sensor as necessary. If sensor is okay, go to next step.
2) Turn ignition on. Check voltage between ground and vehicle
speed sensor harness-side connector terminal No. 3 (Yellow/White
wire). See WIRING DIAGRAMS . If voltage reading is 4.5 volts, problem
is intermittent. If voltage reading is not 4.5 volts, go to next step.
3) Check vehicle speed sensor harness connector. Repair as
necessary. If connector is okay, check circuit between vehicle speed
sensor and instrument cluster. See WIRING DIAGRAMS. Repair as
necessary. If circuit is okay, go to next step.
4) Check voltage between ground and vehicle speed sensor
harness-side connector terminal No. 1 (Black/White wire). See
WIRING DIAGRAMS . Battery voltage should be present. If battery voltage
is present, problem is intermittent. If battery voltage is not
