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.
