An engine coolant temperature sender measures coolant temperature. It does this through changing resistance and sends this information to the onboard computer. The computer uses this and other inputs to calculate the correct amount of fuel delivered. Symptoms of failure include no start, engine flooding, steady check engine light and/or poor fuel economy. Recommended service should be performed every 25,000 to 35,000 miles and consists of cleaning or replacing sensors that are non-functional.

If you have an LT1 Iād buy the OEM sensor. This sensor made the gauge in the cluster peg even though the motor was not overheating
