INSPECTIONN24XcAAENGINE COOLANT TEMPERATURE SWITCH
(ALWAYS-
CLOSED TYPE CHECK)
(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 theoil temperature.
(3) Check to be sure that the engine coolant temperature
switch is switched OFF when the oil temperature reaches
the standard value.
Standard value:
112- 118°C (233-244°F)
CautionUse engine oil for this test; stir it well while heating,
and do not heat more than necessary.
SERVICE POINTS OF INSTALLATIONN24XDM2. INSTALLATION OF ENGINE COOLANT TEMPERATURE
SWITCH (ALWAYS-CLOSED TYPE)
Apply a coating of the specified sealant to the threaded
parts and then install the engine coolant temperature
switches.
