On Board Diagnosis LogicNEEC1534If the cooling fan or another component in the cooling system malfunctions, engine coolant temperature will
rise.
When the engine coolant temperature reaches an abnormally high temperature condition, a malfunction is
indicated.

P1217
1217+Engine coolant temperature reaches an abnormally high
temperature.+Cooling fan (crankshaft driven)
Radiator hose
+Radiator
+Radiator cap
+Water pump
+Thermostat
+Engine coolant temperature sensor
For more information, refer to ªMAIN 11 CAUSES
OF OVERHEATINGº, EC-3348.
CAUTION:
When a malfunction is indicated, be sure to replace the coolant. Refer to MA section, ªChanging Engine
Coolantº. Also, replace the engine oil.
1) Fill radiator with coolant up to specified level with a filling speed of 2 liters per minute. Be sure
to use coolant with the proper mixture ratio. Refer to MA section, ªAnti-freeze Coolant Mixture
Ratioº.
2) After refilling coolant, run engine to ensure that no water-flow noise is emitted.
SEF621W
Overall Function CheckNEEC1535WARNING:
Never remove the radiator cap when the engine is hot. Serious
burns could be caused by high pressure fluid escaping from
the radiator.
Wrap a thick cloth around cap. Carefully remove the cap by
turning it a quarter turn to allow built-up pressure to escape.
Then turn the cap all the way off.
1) Check the coolant level in the reservoir tank and radiator.
Allow engine to cool before checking coolant level.
If the coolant level in the reservoir tank and/or radiator is below
the proper range, skip the following steps and go to ªDiagnos-
tic Procedureº, EC-3345.
2) Confirm whether customer filled the coolant or not. If customer
filled the coolant, skip the following steps and go to ªDiagnos-
tic Procedureº, EC-3345.

Use the chart below to help you find the cause of the symptom.
1. Locate the area where noise occurs.
2. Confirm the type of noise.
3. Specify the operating condition of engine.
4. Check specified noise source.
If necessary, repair or replace these parts.

Trouble Diagnosis of Turbocharger
Preliminary check:
+Check that the engine oil level is between MIN and MAX of
the dipstick. (When the engine oil amount is more than MAX,
the oil flows into the inlet duct through the blow-by gas
passage, and the turbocharger is misjudged failure.)
+Ask the customer if he/she always runs the vehicle in idle
engine speed to cool the oil down after driving.
+Replace the turbocharger assembly when any malfunction is
found after unit inspections specified in the table below.
+If no malfunction is found after the unit inspections, judge that
the turbocharger body has no failure. Check the other parts
again.

Valve Clearance
CHECKING
Check valve clearance while engine is cold and not running.
1. Set the No. 1 piston to TDC on its compression stroke.
+Turn crankshaft pulley clockwise so that the knock pin on
camshaft LH faces straight above. (No position indicator, etc.
is provided on the crankshaft pulley.)
2. Put an alignment mark with paint, etc. on the crankshaft pul-
ley and on the oil pump as an angle indicator.
3. Check only those valves shown in the figure.

+Using a feeler gauge, measure clearance between valve lifter
and camshaft.
+Record any valve clearance measurements which are out of
specification. They will be used later to determine the
required replacement adjusting shim.
Valve clearance for checking (Cold):
Intake
0.24 - 0.32 mm (0.009 - 0.013 in)
Exhaust
0.26 - 0.34 mm (0.010 - 0.013 in)
4. Rotate crankshaft clockwise by one turn to set the No. 4 pis-
ton to TDC on the compression stroke.
