I'm about to install a water temp gauge and the adaptor has just arrived.
if I put the after market sensor in the end it's not leaving much room for the oem 1.
Is the oem one shorter?
*ignore the bolt at the right end. Its loosely in there so that I don't lose it with little ***** about.
That looks like an oil pressue adaptor to me , they usually have a long pipe at one end to screw in block and oem sender fits one end and aftermarket on centre

I found a video somewhere where a guy taps and dies into the water cross over pipe and for the life of me can't find it now
another possibility is the block heater hole?
I really rea't want to cut the front pipe if I can help it.
really wouldnt bother, the car already has a temp gauge, its been years since i had an impreza but on my new subaru based car (2018) the water temp can be read via the obd port
I have a p3 gauge the plugs into the obd port and reads oil temp coolant temp etc without any add ons.
google p3 gauges, expensive but good

It's been a while since I looked under my manifold, but IIRC the cross over pipe already has a sensor + boss, which IIRC is for the ECU water temp sensor.
If you don't want to cut the big radiator pipe, how about the little measly one that goes to the heater core (two hoses under the TMIC to/from the firewall)? Might be able to jig something up there that will allow you to fit the sensor. It's only a (from memory) 16mm hose, though, so you'd definitely need a different adaptor.
I know we discussed this previously on another thread, but I would seriously not run the ECU water temp sensor in a tee-piece like that. I am 99% certain that will mess up the temp readings for the ECU, which could lead to all sorts of problems (over-fuelling being one, for example).

as said before the car reads water temp from the ecu and there are plent of obd2 gauges about

I already have the genome gauges. No point buying more but thank you for the input.

Wasn't going to run the ECU one but the other one next to it.
with it's length it may not be an option any hows.
just wish I saved the video of the guy tapping a new spot on the cross over pipe.
You could potentially cut the middle out of a coolant hose, and use a joiner with a threaded boss in it. This means you don't interfere with the standard sensor, you have a temperature reading from a different point in the system so two points of monitoring, and if you ever remove it you can just put a standard hose back in and you've not got any drilled holes anywhere etc.

This a **** take?
if you read the thread id actually like to tap a second hole for the aftermarket sensor like a video I've seen and cant seem to find again.

I’ve no idea how mechanically competent you are mate so apologies if I offend you. But are you aware of the amount of work to remove, drill, tap, clean and refit that pipe vs cutting a £15 hose in half and fitting a fitting a joiner with sender?

I know cutting the pipe is the easier option but I really like to have wires hidden, less joints and other unsightly things.
I can tap and die 😃
With Covid and limited access to the tools and wanting the gauges done I opted to fit it in the top raidiator hose. It doesn't look too bad and I've hidden the wires well.
Annoyingly it's weeping where the sensor goes in the hole and now that the lower hose has started to weap too (Felt very soft for a while) I'm going to order a silcone kit and change them all.

Weeping sensors are annoying, especially coolant as it leaves that ugly furry mess behind.
Can you add some PTFE tape to the thread (assuming that's where it is leaking from)?

Is this wrong.
