It threads into a 1/4"-18 NPT port and uses internal switching to trigger a warning light or gauge when coolant drops below a safe level, helping to prevent overheating and engine damage. You typically replace this sensor when it fails to read correctly, causing a constant low-coolant warning or failing to alert you to a real loss. The sensor comes with pre-applied red locking compound on the threads for a secure, leak-free installation.
