(b) Hold the tensioner with both hands and push the push rod
strongly against the floor or wall to check that it doesn't
move.
If the push rod moves, replace the tensioner.
(c) Measure the protrusion of the push rod from the housing
end.
Protrusion: 8.0 - 8.8 mm (0.315 - 0.346 in.)
If the protrusion is not as specified, replace the tensioner.
4. M/T:
INSPECT DRIVE BELT TENSION DAMPER
Compress and extend the tension damper rod and check that
there is no abnormal resistance or unusual operation sounds.
If there is any abnormality, replace the tension damper with a
new one.
NOTICE:
When discarding the tension damper, use the following
procedure.
Fully extend the damper rod.
Using a drill, make a hole in the cylinder as shown to
release the gas inside.
CAUTION:
The gas coming out is harmless, but be careful of the chips
which may fly up when drilling.

6. SET NO.1 CYLINDER TO TDC/COMPRESSIO
(a) Turn the crankshaft pulley, and align its groove with timing
mark º0º of the No.1 timing belt cover.
NOTICE:
Always turn the crankshaft clockwise.
(b) Check that the timing marks of the camshaft timing pul-
leys are aligned with the timing marks of the No.4 timing

to determine the required replacement adjusting
shim.
Valve clearance (Cold):
Intake 0.15 - 0.25 mm (0.006 - 0.010 in.)
Exhaust 0.25 - 0.35 mm (0.010 - 0.014 in.)
(b) Turn the crankshaft pulley 1 revolution (360°), and align
the groove with timing mark º0º of the No.1 timing belt cov-
er.
(c) Check only the valves indicated as shown. Measure the
valve clearance. (See procedure in step (a))

(b) Determine the replacement adjusting shim size according
to the following Formula or Charts:
Using a micrometer, measure the thickness of the
removed shim.
Calculate the thickness of a new shim so the valve
clearance comes within specified value.
T .......... Thickness of used shim
A .......... Measured valve clearance
N .......... Thickness of new shim
Intake
N = T + (A - 0.20 mm (0.008 in.))
Exhaust
N = T + (A - 0.30 mm (0.012 in.))
Select a new shim with a thickness as close as pos-
sible to the calculated values.
HINT:
Shims are available in 17 sizes in increments of 0.050 mm
(0.0020 in.), from 2.500 mm (0.0984 in.) to 3.300 mm (0.1299
in.).

Place a new adjusting shim on the valve lifter, with
imprinted numbers facing down.
Press down the valve lifter with SST (A), and re-
move SST (B).

OIL AND FILTER
INSPECTION
1. CHECK OIL QUALITY
Check the oil for deterioration, entry of water, discoloring or thin-
ning.
If oil quality is visibly poor, replace the oil.
Oil grade (2JZ-GE):
API grade SH Energy-Conserving II or SJ, Energy-
Conserving or ILSAC multigrade engine oil.
SAE 5W-30 is the best choice for your vehicle, for
good fuel economy, and good starting in cold weath-
er.
Oil grade (2JZ-GTE):
API grade SH Energy-Conserving II or SJ, Energy-
Conserving or ILSAC multigrade engine oil.
Recommended viscosity is as shown in the illustra-
tion.
2. CHECK ENGINE OIL LEVEL
The oil level should be between the low level and full level marks
on the dipstick.
If low, check for the leakage and add oil up to full level mark.
3. REMOVE ENGINE UNDER COVER
4. 2JZ-GTE:
REMOVE NO.2 AIR TUBE
Loosen the 2 hose clamps, and remove 2 bolts and air tube.
