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.
