AIR CONDITIONING ENGINE
COOLANT TEMPERATURE
SWITCH
(1) Immerse the air conditioning engine coolant temperature switch in oil and then heat (by using a gas stove flame or
similar method) so as to increase the oil temperature.
(2) Check to be sure that the air conditioning engine coolant temperature switch is switched OFF when the oil tempera-ture reaches the standard value.
Standard value:
112-l 18°C (234-244°F)
Caution
The oil used above should be engine oil and should be
stirred well while being heated; do not heat more than
necessary.

ENGINE COOLANT TEMPERATURE SWITCH

(Air conditioning or A/T control)
(1) Remove the engine coolant temperature switch from the
water outlet fitting.
(2) immerse the engine coolant temperature switch in oil and heat by a gas stove or similar method so as to increase the
oil temperature.
(3) Check to be sure that the engine coolant temperature switch is switched ON when the oil temperature reaches
the standard value.
Standard value:
lOO-104% (212-219°F)
CautionUse engine oil for this test; stir it well while heating,
and do not heat more than necessary.

SERVICE ADJUSTMENT PROCEDU&$
AIR CLEANER ELEMENT INSPECTION AND RE- PLACEMENT

(1) Disconnect the volume air flow sensor connector.
(2) Disconnect the connection of the breather hose.
(3) Remove the air intake hose.
(4) Push the air intake hose backward, and remove the air cleaner cover.
Caution
Care must be taken when removing the air cleaner cover, because the volume air flow sensor is at-
tached.
(5) Take out the air cleaner element.
(6) Check the air cleaner element for dirt or clogging; if necessary, clean by using compressed air.
(7) Replace the air cleaner element if the dirt or clogging is serious.
(8) Insert the element into the air cleaner body and install the air cleaner cover.
(9) Install the air intake hose.
(1O)Connect the breather hose and the volume air flow sensor
connector.

and boost hose connections.
(3) Remove the air intake hose on the air cleaner cover side and then move the air intake hose to the front of the air
cleaner body.
(4) Unclamp the air cleaner cover.
Caution
Care must be taken when removing the air cleaner
cover, because the volume air flow sensor is at-
tached.
(5) Take out the air cleaner element.
(6) Check the air cleaner element for dirt or clogging; if necessary, clean by using compressed air.

NOTE
If negative pressure is not normal, it can be assumed that
there is a malfunction in the knock sensor circuit.
(8) Turn off the ignition switch, and connect the connector of the knock sensor.
(9) Use scan tool to erase the diagnostic trouble code or dis- connect the (-) terminal of the battery for 10 seconds or
more.
NOTE
This erases the diagnostic memory of the knock sensor
trouble by disconnecting the knock sensor connector.
TURBOCHARGER WASTE GATE SOLENOID INSPECTION

(1) Operation check Using a hand vaccum pump, apply a negative pressure to
the solenoid valve nipple on which the white vacuum hose
is connected, and check air-tightness when the voltage is
applied to the solenoid valve terminal and when it is released
from the terminal.
