Where is the coolant sensor on a 98 Saturn sw2?

On a 1998 Saturn SW2, the coolant temperature sensor is located on the engine block near the thermostat housing. It is typically found on the driver's side of the engine, just above the oil filter. The sensor is usually a two-wire connector and is positioned in a way that allows it to monitor the coolant temperature accurately. To access it, you may need to remove some components for better visibility.
