Couple Of Qs For The Turbo Owners

[bales 1]

Right have worked out most of the things I have on my engine however have a few parts that I am unsure of which I have shown below;

 

Is this the oil temp sensor

 

This looks like the ignition amplifier of my 8v, I didn't think that this engine would require one of these as it uses a coil pack?

 

This looks like a water temperature sensor, I can't see anywhere specific on the block that it goes?

 

Then there are these two lots of connectors, I understand that they may be some parts someone has bodged on, but then again they may play some important role that you need to keep of the original engine, any ideas?

 

Oh and it appears to have a water cooled oil cooler, however it has a hot water pipe leading into it, so it could be an oil pre-warmer? to be honest I have no idea about it as it doesn't seem to make sense the flow path into and out of it.

 

Thanks for your help, cheers

The first one isnt on my car which is interesting!

2ndIgnition amp

3rd one water temp sensor or warning light sensor

4th goes to the coil pack?

5th one is the fuel pump and ignition relay

and the oil cooler which you just route the water hoses to

 

Hop this helps

4th IIRC is connection for the lambda probe.

5th one as said is the injecttion double relay.

 

Its a heat exchanger, not water oil cooler as many people call it. and has to be plumbed into the main water supply, one connection to the top thermostat>rad hose and I have connected the other to the bottom metal water hose, via a welded on union, or you can connect it to the top hose aswell i think.

 

Pretty sure I have a temp sensor in the front of my sump, will check for you tommorrow mate, not connected it up yet!

iirc the brown water senser is the bitronic senser and redundant in a 205, it controls the fans and aircon ect. or was it the green one... i think the green was for temp warning light n guage, blue is the ecu senser. 99% brown is in needed.

 

everything else already mentioned, the 4 pin plug is the landa senser.

Wondered why I hadnt seen that brown plugged sensor before, lol

 

ON mine the blue plug is for the gauge.

 

Looking at that sump again, that brass tap looks awfully new, compared to the rest of the engine?

 

Inferno, is it definately an oil temp in the front of the sump? and not oil level?

yes the oil temp is in the sump, the oil level is on the back of the block where a 1.9 dipstick would be

Thats it. Blue is the Temp Gauge Sender, Green is the Coolant Temp Sensor for the ECU and as said, Brown is the BITRON sensor. The only other thing it does except control the fans is to light up the over temperature warning lamp. Maybe in a 205 the BITRON can be swapped for a 205 warning light sensor. In any case the BITRON works in the reverse sense to a standard sensor. It's resistance goes up with rising temperature (or is it the other way around?) in any case its opposite to the gauge sender and the CTS.

 

I confirm the front sensor on the sump is the Oil Temperature Sensor.

the bitron senser has a wierd thread iirc, and i couldnt find a suitable senser to put in its place, i was looking i think for a fan control switch and ended up using an in line senser in the top hose.
