Sensor adpators?
Does anyone know where I can get an adaptor to mount my GM water temp sensor into my Zetec thermostat housing?
I believe i need to go up from a 1/4" npt hole in the housing to a 3/8" npt for the sensor.

Your best bet is to go to a good hydraulic pipe fittings supplier. Take the bits with you and see what he's got that fits.
In my experience these guys are very helpful and knowledgeable.

Going from a small hole to a bigger one is always a bit of a problem especially if your sensor is not fully in the flow, may read a little lower than
actual.
I would look seriously at another mounting point, possibly using an adaptor in a pipe to the rad

FWIT on chris-p-duck's zetec, the sensor supplied by extra efi screwed straight into the top of the t'stat housing - i'm sure that
is a GM sensor....

I would prefer to mount it in the orginal hole as it get hotter faster, to regulate my warm up enrichment. It's mounted cylinder head side of
the thermostat.
Unfortunately the blacktop sensors are a diffrent size thread to the silvertops, sometimes i wish i'd brought one of those
Pipe fitter next week then.

I use the standard Zetec sensor and recalibrate the ECU using Easytherm. All you need, as I recall, are 3 or 4 points for resistance across a
reasonable temperature range.
For what it's worth mine were:
8 deg C = 68.5k ohm
27 deg C = 26.5k ohm
41 deg C = 16.1k ohm
98 deg C = 2.2k ohm

Ian, hope your keeping well, i've tried the silvertop values in easytherm, the lower temps are ok but upper (over 87deg) go out of kilter.

Hi Dan,
Yep, all well. Into the winter upgrades now! Working on an airbox and remote filter to hush it up a bit, plus new front brakes.
It's quite easy to calibrate the sensor yourself if you have a multimeter. If you can get a thermometer to read alongside the sensor, great.
If not you put some ice in a beaker and let it start to thaw so there's a mix of ice and water you can assume that's zero, stick the
sensor in and measure the resistance. Boil some water, let it stabilize at a vigorous simmer and you can assume that's 100. I think I did the
middle numbers in luke warm water with a cheap thermometer.
Good luck.
Ian
