Technical Uno Turbo engine sensor identify ( HELP! )
Number 2 - Temperature sensor on the Cylinder Head (Registers the heat guage on the Speedometer console)
A bit futher down is the oil level sensor on the Block (Registers the oil level) But of course you knew this....
Number 1 - No idea !

thank you for your answer, however, photo 1 and photo 2 are showing the same connector/sensor .... photo 3 is different, can you be more specific ? water temp is not moving on the clocks no matter where i connect the wire ( i have 2 set of clocks, all act same way )
thanks
first one looks like your thermostat so will be coolant temp, i have mk2 so bit diff
Yes, the first one (pictures one and two) is a coolant temperature sensor for the fuel injection ECU.
The second one (picture three) is the sender for the temperature gauge.
Although the two senders measure the same thing (temperature of the cooling system) they are separate systems and the wiring must not be mixed up.
There is actually a third sender on the radiator itself - that is for turning on the radiator fan.

I thought so, thanks for confirming that!
Original temp sensor would have a blue plastic wire-clip-type plug integrated with the sensor.

Thank you very much for your answer, Tommorow I'll receive at local car parts store a new temp sender sensor....... hope that will fix my problem. I'll let you know !
PS. how do I get the air off from coolant system ? any "special" tricks ?
thanks.

on the other side of the water pump there is a sensor with a blue connector .....
Open the radiator filler (at the front of the engine bay) so you can keep topping it up with water. Top it up as far as you can get it but don't put the top back on.
At the back of the engine bay on the left hand side (near the carb) should be a pipe with a plastic screw in it.
Get the engine going, then lift the screw point on the pipe as high as it will go, then undo the screw. This will pump the water round the system, and the air bubbles caught in the system will naturally rise to the highest point (where the screw is undone) and come out of the system.
Make sure you are filling the reservoir with more water/coolant/anti freeze (a mixture thereof) as the level drops.
It might make sence to have an extra pair of hands on site to top up the water level and rev the engine a little to help you out.
(at least, that's how I did it. Others might improve on the method!)
It's a bit different on the Uno Turbo
the header tank is at the back of the engine bay (not on the radiator) and as it's the highest point in the system, there is no bleed screw . just add coolant and it sorts it's self out
See, there's me, trying to be helpful, and all along, I was, just using, too, many, commas.
Bleeding an X1/9 is a bit more complicated than a uno??, the bleed screw is on the radiator, lower/offside

wow, thank you for the advices. I have buyed a new engine temp sensor, mounted, I'll start the engine and see if it shows me any temperature on the clocks. then I'll start to get the air out of the system .
Once again, THANK YOU ALL !

You see the

Hope it all works for you!

OK - so, Ucof tried, Louie corrected, but charlie gets the award... I bet no-one else noticed this was an X1/9!
So yes, there is a rubber bung to remove above the radiator in the front luggage compartment, left-front corner of the car. There is then a long-headed 'bolt' on the radiator, that takes a 6mm Allen key to remove. See picture.
The drain plugs are fitted to the coolant pipes under the front floor (see second picture). I owned this fairly tidy '88 X1/9 for about a year but sold it in 2006
Leave the 'bolt' out while you fill the system through the expansion tank at the rear of the car. Turn the heater on also (if the control is broken, you can find the water valve if you look upwards from the right footwell).
There is a correct process to follow - basically, run the engine for a short while and then refit the 'bolt' while coolant is overflowing.

coolant temperature is showed at the clocks, I think the engine block temp sesor was broken. now i have to figure out the level of gas ( wich is now working on clocks ) . and YES , is a X1/9 with a uno turbo engine .
Thnak you all for th help
