A GM Original Equipment Engine Oil Pressure Sensor provides an electrical oil pressure signal to the engine control module, and is a GM-recommended replacement for your vehicle's original component. It measures the oil pressure in your vehicle's engine and will alert you through the oil pressure gauge or warning lamp if the oil pressure falls below the specified pressure. This original equipment engine oil pressure sensor has been manufactured to fit your specific GM vehicle, providing the same performance, durability, and service life you expect from General Motors.Features & Benefits:Undergo the same stringent testing process as the original partGM-recommended replacement part for your GM vehicle's original factory componentOffering the quality, reliability, and durability of GM OEManufactured to GM OE specification for fit, form, and function cooler thermostat.
The point of the low temp stat is to get that coolant out to the radiator for temperature regulation at a lower temperature, thus keeping the whole engine at a lower temperature (provided the radiator has no problem keeping up with dissipating the heat). There a few reasons to want to do this:

-Cooler engine/combustion chambers less likely to knock/ping under high load
-Cooler engine does not have as large of a heat cycling range
-Cooler external engine parts and wiring lasts longer and takes less heat wear
-Cooler engine can generate more heat (make more power) without overheating
-It can also allow the engine to be run at full throttle (maximum heat produced) for a longer period of time without overheating
-Engine stays cooler when idling for long periods of time (only if fan is running at the same lower temp as well)
-helps to keep oil cooler
