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 upper 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 you are using the 1/8 NPT version, you
can use the supplied ring style terminal around the sensor to ground it. If you are
using the 3/8 NPT version, you can strip some insulation off the end of
a wire and insert it into the radiator hose prior to slipping
it onto the adapter such that it is sandwiched between the adapter and the
radiator hose, under the hose clamp.
