Refrigerant Temperature Switch Continuity Check

1. Immerse the refrigerant-temperature switch in engine oil.
2. Use an ohmmeter to check continuity when the engine oil has become heated.

Standard value:
Item = Temperature
Continuity (ON) = Less than approx. 165° C (329° F)
No continuity (OFF) = Approx. 165° C (329° F) or more [until the temperature drops to approx. 110° C (230° F) when OFF]

CAUTION: Do not heat the oil more than necessary.
