This used OEM Porsche Coolant Level Sensor (98764150300) monitors the coolant reservoir in Boxster and Cayman models with naturally aspirated H6 engines—2.7L, 2.9L, and 3.4L. When the sensor fails, it often triggers a false low-coolant warning or an intermittent check-engine light. Also known simply as a coolant level switch, it mounts in the expansion tank and signals the PCM when fluid drops below safe levels.
