Aluminum Black Inline Radiator Hose Temperature Sensor Adapter 3/8 NPT

Aluminum Black Inline Radiator Hose Temperature Sensor Adapter 3/8 NPT

Following are the components included:

CNC machined temperature sensor adapter Two stainless steel hose clamps(40-46mm)

General Info

This is a CNC machined aluminum adapter designed to mount inline into a 1.5" ID radiator hose. This adapter allows you to put a temperature sensor with 3/8 NPT threads in your radiator hose. This could be useful if you are looking to add an auxiliary water temperature gauge or fan control kit but do not have a port in the intake manifold or water pump to mount the sensor. The adapter also includes two stainless steel hose clamps and installation instructions. (A note regarding hose clamps: Many "stainless" hose clamps actually use a zinc plated steel screw, which will quickly corrode or rust in a harsh under-hood environment. The hose clamps that I include with this adapter are 100% stainless for maximum corrosion resistance.) This adapter also features a stainless steel grounding screw along with a quick-disconnect electrical terminal to make it easy to provide an engine ground to your sensor.

Please be aware that no coolant will flow through your radiator hose until the thermostat opens. Therefore, a sensor mounted in the upper radiator hose will read under-hood temperature until your thermostat opens, at which point it will begin reading the engine coolant temperature.

To install the adapter, you simply cut your radiator hose in the location where you want to mount the adapter, slip it in place, and use the supplied hose clamps to tighten it down. Your temperature sensor screws into the threaded port. You will need to consult the documentation for the sensor you are using to determine if it requires a ground or not. Some sensors provide their own ground - these usually have two or more wires. Other sensors get their ground through the body of the sensor itself - these usually only have one wire. If a sensor does not provide its own ground, you will need to provide it with one by connecting a wire between the sensor (or the adapter) and a convenient ground source such as a bolt on your engine. If a ground is necessary, you can use the provided grounding screw. A quick-disconnect for the ground is also included.
