aaagh coolant buzzer

nikp · August 19, 2006, 06:12:31 PM

Ok, i got my buzzer to go off, so now have a bit of expereince with this. The temp sensor gauge plug needs to be plugged in - this is the white/brown wire, it comes off the loom that is coming off the back of the engine and going towards the bulk head. If you locate the oil pressure switch (Right above the rear most HT plugs) - it\'s cylindrical in shape - the temp sensor is located right besdie this sensor. It\'s really small and close to the engine. It\'s on the head light side of the oil pressure sensor. Very difficult to see - easier to feel.

Then there are 2 cables that need to be plugged together that are behind the power steering pump/air con compressor. On the american forums they say its a white plug and black plug, but i actually found that they\'re both black on mine (There is a white plug though!!) hope that helps.

Just taken the elbow off to give me a bit more room to play with, gonna give this a shot now!

Wish me luck :WaveBye

Okay...
It\'s too dark too see much now, so I\'m up at the crack of dawn now to sort this out.

After strugglin to find it I\'m convinced mine doesnt exist now :p

I\'ve had a read and a looked at the piccies on this post of your\'s too.

Still can\'t locate that. Found the white plugs, etc, and i they\'re connected.
One thing that troubles me is the length of the wire. If you have a look at the piccy above then the white/brown wire is kinda short, and there\'s no where for it to go. So unless that other wire that I can\'t find is pretty long then I don\'t really hav a clue.
One end of the w/b wire, thats closest to the PS reservoir is in the loom, (black pipe thing) and the other side doesnt havea connector, so could this have been pulled off?

Thanks again

There\'s no way in hell that you don\'t have a coolant temp sensor: it\'s just a bugger to find. You really can\'t see it - you might possibly be able to see it if you know what you\'re looking for, otherwise, you\'ve got to feel for it. I have done this all today, so I know!

Lol I know mate, I was just talking crap, hence the :p

I\'ll have to have another look.
But the size of this wire still concerns me. It\'s pretty short, and was covered in insualting tape. Could it simply have been taped somewhere to ground it?
Which is a question in itself. Where would I tape it to ground it (if at all possible?) :Hammer

Now then.
Grounding that little wire seemed to do the trick :evillaugh

Not the best of solutions but seeing as i\'m off to a meet in a bit it\'l do to keep me sane.

I reckon it was previously ground also, as the wire is very short, and theres no sign of it\'s partner anywhere

Long term: gonna havta locate that little connecter and join a new wire to it. Will be a bit difficult I guess, is removing the oil(?) pipes that are in the way the only method of cleanly gaining access to this spot?

No, you can gain access to it with just the intake elbow removed. It is a bugger to find though! I made myself a little extension cable yesterday, to aid me connecting to it, i would advise doing something similar. Say about 15cm long - you can use normal male and female electrical spade connectors to do this.

Ah, here we go: I have found i have a picture of my engine out, with the temp gauge sensor circled. This should help you a lot.

Bloomin \'eck that is a small bit!!!
Is that round bit just above and to the right where the oil filter get\'s plonked on?
I reckon I will have to attempt this with a new wire thats connected to the sensor then get a couple of spade connectors from maplins.
nik mate :god
Absolute leg end!
