8. REMOVE CLUTCH DISC ASSY
NOTICE:
Keep the lining part of the clutch disc assy, the pressure plate and surface of the flywheel sub±assy
away from oil and foreign attachment.
9. INSPECT CLUTCH DISC ASSY
(a) Using vernier calipers, measure the rivet head depth.
Maximum rivet depth: 0.3 mm (0.012 in.)
Replace the clutch disc assy as necessary.
(b) Install the clutch disc assy to the transaxle assy.
NOTICE:
Take care not to insert the clutch disc assy in the wrong
direction.
(c) Using a dial gage, check the clutch disc assy runout.
Minimum runout: 0.8 mm (0.031 in.)
Replace the clutch disc assy as necessary.
10. INSPECT CLUTCH COVER ASSY
(a) Using vernier calipers, inspect the diaphragm spring for
the depth and width of wear.
Maximum:
A (Depth): 0.5 mm (0.020 in.)
B (Width): 6.0 mm (0.236 in.)
Replace the clutch cover assy as necessary.
11. INSPECT FLYWHEEL SUB±ASSY
(a) Using a dial gage, inspect the flywheel sub±assy runout.
Maximum runout: 0.1 mm (0.004 in.)

ON±VEHICLE INSPECTION
1. INSPECT COOLING SYSTEM FOR LEAKS
CAUTION:
To avoid the danger of being burned, do not remove the ra-
diator cap while the engine and radiator are still hot. Ther-
mal expansion will cause hot engine coolant and steam to
blow out from the radiator.
(a) Remove the radiator support opening cover.
(b) Remove the engine room cover side.
(c) Fill the radiator with coolant and attach a radiator cap tes-
ter.
(d) Warm up the engine.
(e) Pump it to 137 kPa (1.4 kgf/cm
2, 19.9 psi), and check that
the pressure does not drop.
If the pressure drops, check the hoses, radiator and water
pump for leaks. If there are no signs or traces of external coolant
leaks, check the heater core, cylinder block and head.
(f) Reinstall the engine room cover side.
(g) Reinstall the radiator support opening cover.
2. CHECK ENGINE COOLANT LEVEL AT RESERVOIR
(a) The engine coolant should be between the ºLOWº and ºFULLº lines, when the engine is cold.
If low, check for leaks and add ºToyota Long Life Coolantº or equivalent up to the ºFULLº line.
3. CHECK ENGINE COOLANT QUALITY
(a) Remove the radiator cap.
CAUTION:
To avoid the danger of being burned, do not remove the radiator cap while the engine and radiator
are still hot. Thermal expansion will cause hot engine coolant and steam to blow out from the radiator.
(b) Check if there is any excessive deposits of rust or scale around the radiator cap and radiator filler hole;
the coolant should be free from oil.
If excessively dirty, replace the coolant.
(c) Reinstall the radiator cap.

1. INSPECT MASS AIR FLOW METER
(a) Output voltage inspection.
(1) Apply battery voltage across terminals 1 (+B) and 2
(E2G).
(2) Using a voltmeter, connect the positive (+) tester
probe to terminal 3 (VG), and negative (±) tester
probe to terminal 2 (E2G).
(3) Blow air into the MAF meter, and check that the volt-
age fluctuates.
(b) Resistance inspection.
(1) Using an ohmmeter, measure the resistance be-
tween terminals 4 (THA) and 5 (E2).

(b) Movement inspection.
(1) Connect the positive (+) lead from the battery to ter-
minal 1 and negative (±) lead to terminal 2, and
check the movement of the valve.
NOTICE:
Confirm the valve does not adhere.
HINT:
Bad returning of the valve by entrance of foreign objects causes
subtle pressure leak to the advanced direction. Then, DTC can
be detected.
3. INSPECT THROTTLE BODY ASSY
(a) Check throttle body.
(1) Check that throttle valve shaft is not rickety.
(2) Check that each port is not stopped up.
(3) Check that throttle valve opens and closes smooth-
ly.
(4) Check that there is no clearance between the
throttle stop screw and throttle lever when the
closed throttle position.
