            The coolant temperature sensor is pivotal in the continued operation of your car's radiator and cooling system, so replacing the sensor when it breaks down is critical. Finding replacement sensors is not that hard nowadays, and among the most popular models right now is the AEM coolant temperature sensor.

            Specializing in a wide selection of automotive precision electronics, AEM offers coolant temperature sensors that are designed to provide accurate readings under high temperature conditions. In this review we tested several sets of AEM's sensors.

            Features

            • One wire to sensor ground and one wire to sensor signal
            • Wire strip length: 0.175-0.200 inches
            • Thread size: 1/8 inches
            • Operating temperature: sensor tip -40C to 200C, connector -40C to 150C
            • Brass body
            • Aluminum bungs for custom applications
            • Includes mating connector, pins & wire seals

            The upside

            • Accurate readings. We did a side-by-side comparison of the sensors and the readings are well within their parameters. The temperature and resistance values do have a slight curve, but the data sheet provided can help clear things up.
            • High quality construction. The sensor body is made of solid brass and with full NPT threading. The sensor also comes with an aluminum bung in case you need to use the sensor with modifications.
            • Comes with the necessary fasteners. The sensors include everything needed to mount the device onto the engine block, saving you time and money in finding the necessary fasteners yourself.

            The downside

            • Installation has a bit of a learning curve. Installation of the sensor might prove to be difficult in particular to those with little or no experience in repairing or replacing car components. And given the fact that a temperature sensor that is not installed properly may give inaccurate readings, it may be best to have the sensor installed by a mechanic.

            The bottom line

            The AEM coolant temperature sensor is a viable choice for anyone looking for a good replacement temperature sensor in the vehicle. The sensor is made of high quality materials and provides accurate readings that we've come to expect from AEM sensors. It is not advised, however, to install this sensor by yourself if you are not that confident with your skills in car repair, as getting it mounted properly requires a bit of know-how to accomplish. But if done correctly, the sensor will provide years of accurate performance for your ride.
