Coolant expansion tank sensor 2 pin connector
« on: September 27, 2021, 11:50:09 pm »
Desperately seeking, if it has some cable already attached would be even better  :)

Looked on heritage parts and couldn’t find the right plug, and nothing on eBay that I can see… you’d think they’d be a 10 a penny

It’s got the 2 raised slots on it (the one on heritage only has 1 in the middle), sorry can’t seem to post pictures.

Thanks all

They are junior power timer (jpt) connectors but as you say most 2-pin ones only have the one locating slot in them. I have managed to find somewhere with the two slot version:

Not sure if the spacing is right but there is a diagram on there. Need to see if I can find it on Farnell or anywhere else.

What is actually wrong with yours? Is the plastic shell itself damaged?

oh this might be it, need to check the width of the connector though as from memory it seems narrow for the header tank connector:

Thanks mate.  Unfortunately you are correct the spacing isn’t right.   Hopefully I’ve managed to resize the image so it’ll load nowadays an attachment.   I can’t figure out how to unlock this particular connecter, normally you should be able to slide the locker over but I’m fudged if I can figure it out with this one!!

Scratch that, Delphi/Aptiv I think have the OE tooling.

Check the datasheet on this for dimensions:

Thanks Andy. 

I managed to find this

https://www.ebay.co.uk/itm/Horn-2-Pin-Connector-Pre-Wired-For-Audi-Seat-Skoda-VW-01450173-01450185-/274813417324?mkcid=16&mkevt=1&_trksid=p2349624.m46890.l49286&mkrid=710-127635-2958-0

Which is very close but not exactly the same, going to see if I can make it work (image attached)

That did fit.   Still getting the low fluid/pressure warning light though.   

Next port of call.   Wires where a bit thicker so maybe too much resistance now to expansion tank sensor? Presume I can just short across the two wires to check this?  I’m not convinced it’s pressurising the system though either, will take another look tomorrow.    Coolant either shows 0 or if it does move it never goes to more than 70 (was doing this before I changed the plug as well but when I saw the plug was u/s I figured was the cause), if I short across the temp sensor it goes to top so not a u/s gauge.  Running larger intercooler.   I’ve seen other owners have similar issues in the past but not found the cure yet  ;D
