Engine Oil Maintenance Information
Poor oil maintenance reduces the engine oil
lubrication and cooling capacities. As a result,
internal engine parts can be damaged resulting
in abnormal wear to internal engine parts,
excessive carbon deposits, sludge, and other
various conditions. An inspection for these
conditions and others may be required prior to
engine approval.
Piston Ring Deposits
NOTICE
Engine oil is used to lubricate, cool, and
operate various engine parts. Engine oil
changes and engine oil level checks are
required on a regular basis for all engines.
Oil Sludge
Engine oil level checks and top-ups are
recommended if they are needed prior to
the end of an oil change interval.

Bearing Inspection:
1. Connect the main hose (shop air supply) and
test hose to the bearing tool (with other end of
the test hose disconnected). (The power to the
bearing tool main unit is not necessary at this
time.)
Confirm the shop air pressure and AP/VC
pressures on the bearing tool meet
requirements. The correct ranges for AP/VC air
pressures are also indicated with red/blue
decals on the gauges. Using STUI in the GDS,
take and submit a picture of the gauges with
the pressure levels clearly visible and the VIN
in the background of the photo (RO or last 6
digits written on paper) for records.
Shop air supply: 50 psi minimum
AP/VC air pressure calibration check:
a) Connect the main air compressor hose.
b) Connect the test hose. (The other end of the
test hose should be left disconnected from
the spark plug rod.)
c) Confirm that the AP/VC toggle switch at top
is in the middle position.
d) Inspect the AP/C gauge indicators and
compare to the specification range:
 AP: 0.1 ~ 0.11MPa
 VC: -73 ~ -83Kpa
NOTICE
Do not continue if any of the above readings are out of specification range.
 Adjust shop air to consistently provide at least 50 PSI of air pressure or greater.
 Do not use a portable air compressor to perform the bearing clearance testing.
 Be sure to check that the shop air water separator is functioning correctly.
 If any of the AP/VC air pressure indications are out of the specified range,
recalibration of the Bearing Clearance Tester is required.
o Refer to latest instructions outlined in the Engine Bearing Clearance Tester
Calibration Procedure TSB 20-GI-009H or later for calibration procedure.

9. Turn the ignition ‘OFF’ and remove the VCI.
10. Follow the instructions on the GDS to start the test and select ‘Next’.
NOTICE


For the following steps, the Crank Rotator Tool or a long handled wrench should be
used for moving the crankshaft slowly and precisely.
Ensure the test hose is disconnected from the clearance gauge when finding TDC
piston depth.
Please take note of the following crank/piston position definitions.

BTDC (Before Top Dead Center)

TDC (Top Dead Center)  Find TDC during the compression stroke.

ATDC (After Top Dead Center)
In the following steps, the TDC point for testing must be at MAX (piston height) value
minus 0.03mm as the crank has moved slightly into ATDC (from its TDC dwell point).
 If TDC is difficult to find, refer to Shop Manual Section Location: Engine Mechanical
System > Timing System > Timing Chain
TSB #: 21-01-024H

11. To find TDC compression (TDC), rotate the crankshaft with the crank rotator SST at least one
cycle (1/2 turn). (If the SST does not fit the specific vehicle type, remove the front passenger wheel
and wheel liner or underbody tray as needed to rotate the crankshaft using standard shop tools.)
IMPORTANT


For the step below, the engine must be rotated SLOWLY using the crank rotator SST.
o Abrupt or erratic movements may cause improper TDC setup and test errors.
Do NOT stop rotating the engine before reaching MAX TDC, especially during the
initial rotation towards TDC where the value may be at 0mm and change all the
sudden.
o Be sure to find TDC correctly by slowly and slightly nudging the engine a little
more to verify no change in value to confirm that the piston is at MAX TDC.
 Monitor the piston height value on GDS screen
or the clearance gauge SST while rotating the
engine clockwise using the Crank Rotator Tool.
 Rotate the engine SLOWLY as the value
increases towards a MAX value. (BTDC 
TDC)
 When the value changes direction
(increasing/BTDC  TDC 
decreasing/ATDC), stop rotating the crank
when the piston height is at MAX value
minus 0.03mm.
NOTICE
The testing point is slightly towards ATDC
from TDC when the piston has moved
down 0.03mm from its highest position.
12. Select ‘Next’ when TDC is found.
 Ideal set point for testing from TDC is found
when the maximum value minus 0.03mm is
reached on the clearance gauge SST (F).
 The value is also displayed on the GDS.
F
13. Once the set point for bearing testing is found,
select ‘Start’ in the GDS screen and proceed
directly to the next step below.
 Do not turn the crank rotator SST until
instructed to do so.
NOTICE
The value at TDC varies depending on the
specific vehicle and engine type.

14. Connect the test hose (1) to the spark plug rod
SST and to the bearing tool SST.
15. Connect the SST power cables to a fully
charged 12V battery or to an external AC/DC
power supply.
 Turn the bearing tool SST power switch
‘ON’.
NOTICE
*** Bearing Tool SST Power Check ***
a) Supply 12 volts (or an alternate external AC/DC 13.8 volt power supply with at least ~2
amp output) to the power cable (3) connected to the bearing tool SST.
b) Turn power switch to ON.
c) Toggle AP/VC transfer switch between AP <> VC.
 The solenoids should “click” while switching between AP/VC when the unit is ON.
 If the solenoids are not switching, then check the power cable or the power supply.
16. Locate the AP/VC switch on the bearing
tool SST and switch it to the AP Position.
17. Follow the instructions on the GDS to test
each cylinder. Cylinder #1 is checked first.
 The cylinders will be checked per the
engine firing order: #1→#3→#4→#2.
18. On the bearing tool SST, change the AP/VC
switch to the VC position when instructed by
the GDS.

NOTICE
If the bearing measurement value does
not change when the AP/VC is
switched or the “Unable to measure”
message appears on the GDS, rotate
the crankshaft further as the exhaust
valves could be open. Set the
crankshaft to TDC again (Step 11).
Ensure the test hose is disconnected
from the clearance gauge SST when
finding TDC.
19. Continue following the instructions on the GDS to
complete the bearing inspection. Check the engine oil
level and select the level in the GDS.
20. If the test result is “PASS”:
a) Save a screenshot of the results screen.
 If there is audible engine noise:
 Refer to HTSS "Fix it Right“ under
symptom: “Engine NoiseUndetermined”
