Abstract
A temperature sensor used to monitor coolant and an automobile coolant system. The temperature sensor includes a one-piece housing having a sensor portion and a connector portion. A sensor assembly, including a sensor having a pair of terminals connected thereto is disposed within the housing. The sensor portion includes a sensor tip having a configuration conducive to improving thermal transfer from the coolant through the sensor tip to the sensor. A thermally conductive material may also be used to improve thermal or heat transfer to the sensor.
