Checking Cooling SystemELS001JR
WARNING:
Never remove the radiator cap and reservoir tank cap when the engine is hot. Serious burns could
occur from high pressure engine coolant escaping from the radiator and the reservoir tank. Wrap a
thick cloth around the cap. Slowly turn it a quarter turn to allow built-up pressure to escape. Carefully
remove the cap by turning it all the way.
CHECKING COOLING SYSTEM HOSES
Check hoses for improper attachment, leaks, cracks, damage, loose connections, chafing and deterioration.
CHECKING RADIATOR
Check radiator for mud or clogging. If necessary, clean radiator as follows.
lBe careful not to bend or damage the radiator fins.
lWhen radiator is cleaned without removal, remove all surrounding parts such as cooling fan, radiator
shroud and horns. Then tape the harness and connectors to prevent water from entering.
1. Apply water by hose to the back side of the radiator core vertically downwards.
2. Apply water again to all radiator core surface once per minute.
3. Stop washing if any stains no longer flow out from the radiator.
4. Blow air into the back side of radiator core vertically downwards.
lUse compressed air lower than 490 kpa (4.9 bar, 5 kg/cm2, 71psi) and keep distance more than 30
cm(11.8 in).
5. Blow air again into all the radiator core surface once per minute until no water sprays out.
CHECKING RESERVOIR TANK CAP
lInspect valve seat of reservoir tank cap.
–Check if valve seat is swollen to the extent that the edge of the
plunger cannot be seen when watching it vertically from the top.
–Check if valve seat has no soil and damage.

closing conditions of negative-pressure valve.
lCheck reservoir tank cap relief pressure.
–When connecting reservoir tank cap to the radiator cap tester
adapter (SST) and the radiator cap tester (Commercial service
tool), apply engine coolant to the cap seal surface.
lReplace reservoir tank cap if there is an unusualness in negative pressure value, or if the relief pressure
falls below the limit.
CAUTION:
When installing a radiator cap and reservoir tank cap, thoroughly wipe out the radiator and reservoir
tank filler neck to remove any waxy residue or foreign material.
CHECKING RADIATOR SYSTEM FOR LEAKS
lTo check for leaks of cooling system, apply pressure to the res-
ervoir tank (1) with the radiator cap tester (commercial service
tool) (A) and the radiator cap tester adapter (B) [SST:
EG17650301].
WARNING:
Do not remove reservoir tank cap and/or radiator cap when
engine is hot. Serious burns could occur from high pres-
sure engine coolant escaping from reservoir tank and/or
radiator.
CAUTION:
Higher test pressure than specified may cause cooling system damage.

CHECKING RELIEF OIL PRESSURE
CAUTION:
Make sure that belt tension is normal before starting the following procedure.
1. Connect the hydraulic pressure gauge [SST] between oil pump
discharge connector and high-pressure hose. Bleed air from the
hydraulic circuit while opening valve fully. Refer toPS-6, "
Air
Bleeding Hydraulic System".
2. Start engine. Run engine until oil temperature reaches 50 to
80°C(122to176°F).
CAUTION:
lLeave the valve of the hydraulic pressure gauge [SST]
fully open while starting and running engine. If engine is
started with the valve closed, the hydraulic pressure in
oil pump goes up to the relief pressure along with
unusual increase of oil temperature.
lBe sure to keep hose clear or belts and other parts when
engineisstarted.
3. Fully close the hydraulic pressure gauge [SST] valve with
engine at idle and measure the relief oil pressure.
CAUTION:
Never keep valve closed for 10 seconds or longer.
4. Open the valve slowly after measuring. Repair oil pump is the
relief oil pressure is outside the standard. Refer toPS-26, "
Dis-
assembly and Assembly".
5. After inspection, disconnect the hydraulic pressure gauge [SST] from hydraulic circuit, then add fluid and
bleed air. Refer toPS-6, "

TRUNK
Trunk noises are often caused by a loose jack or loose items put into the trunk by the owner.
In addition look for:
1. Trunk lid dumpers out of adjustment
2. Trunk lid striker out of adjustment
3. Trunk lid torsion bars knocking together
4. A loose license plate or bracket
Most of these incidents can be repaired by adjusting, securing or insulating the item(s) or component(s) caus-
ing the noise.
SUNROOF/HEADLINING
Noises in the sunroof/headlining area can often be traced to one of the following:
1. Sunroof lid, rail, linkage or seals making a rattle or light knocking noise
2. Sunvisor shaft shaking in the holder
3. Front or rear windshield touching headlining and squeaking
Again, pressing on the components to stop the noise while duplicating the conditions can isolate most of these
incidents. Repairs usually consist of insulating with felt cloth tape.
SEATS
When isolating seat noise it's important to note the position the seat is in and the load placed on the seat when
the noise is present. These conditions should be duplicated when verifying and isolating the cause of the
noise.
Cause of seat noise include:
1. Headrest rods and holder
2. A squeak between the seat pad cushion and frame
3. Rear seatback lock and bracket
These noises can be isolated by moving or pressing on the suspected components while duplicating the con-
ditions under which the noise occurs. Most of these incidents can be repaired by repositioning the component
or applying urethane tape to the contact area.
UNDERHOOD
Some interior noise may be caused by components under the hood or on the engine wall. The noise is then
transmitted into the passenger compartment.
Causes of transmitted underhood noise include:
1. Any component mounted to the engine wall
2. Components that pass through the engine wall
3. Engine wall mounts and connectors
4. Loose radiator mounting pins
5. Hood bumpers out of adjustment
6. Hood striker out of adjustment
These noises can be difficult to isolate since they cannot be reached from the interior of the vehicle. The best
method is to secure, move or insulate one component at a time and test drive the vehicle. Also, engine RPM
or load can be changed to isolate the noise. Repairs can usually be made by moving, adjusting, securing, or
insulating the component causing the noise.
