Inline radiator hose temperature sensor adapter
(For 1 1/2" ID radiator hose)
This is a CNC machined aluminum adapter designed to mount inline into a 1 1/2"
ID radiator hose.
There are two versions of this adapter; one has a 1/8 NPT threaded hole, and
the other has a 3/8 NPT threaded hole.
This will allow you to
put a temperature sensor in your radiator hose. This could be useful
if you are looking to add an auxiliary water temperature gauge 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.
These adapters will work in any vehicle which has a 1 1/2" ID radiator
hose that has about four inches worth of straight section for the adapter
to be mounted in. Please be aware that no coolant will flow through your
upper 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. Then, screw your temperature
sensor into the threaded port. If your temperature sensor requires a
ground, the 1/8 NPT version includes a ring style electrical terminal
which you can thread the sensor through. The 3/8 NPT version includes a
grounding screw and quick-disconnect terminal on the side of the
adapter itself.
Note: The 3/8 NPT version normally includes a ground screw, however I also have a limited quantity of this adapter in the 3/8 NPT size which does not have
the grounding screw provisions. These will work just fine for a temperature sensor
which supplies its own ground wire (normally these are 2 wire sensors). This version
can also be provided a ground by slipping your ground wire between the adapter and the hose.
