There are two connectors in my 97 2.3 4cyl. One is right on the thermostat housing and the other is a few inches down the line right in the coolant line. Are they the same part serving different purposes or are they separate parts all together? My motor is not reaching normal operation temp. I have flushed the system at the oil change place and back flushed the heater core in my driveway. I have also changed the fan clutch and water pump and thermostat. All yielding the same result, motor still won't reach normal operating temperature. All thoughts and ideas are welcome. Thanks
