Coolant Temperature Switch Test
- Remove switch from radiator or engine block. Place switch in container of coolant with thermometer. Connect ohmmeter to switch terminals. Slowly heat coolant.
- Note temperature at which continuity exists between switch terminals. Continuity should be present with coolant temperature greater than 207°F (97°C) and continuity should not be present with temperature less than 194°F (90°C). Replace switch if not operating as described.
