aaagh coolant buzzer

[Oedipus Rex]

doing my head in.

There\'s nothing wrong with my coolant levels at all. Take off the filler neck cap and the colant is visible, check the expansion tank plenty in there. However the coolant buzzer is giong off all the bloody time, well pretty often anyhow. I even had the engine on and the coolant buzzer going off. Took off the cap and red hot coolant came spluttering out, so it was right up to the top of the neck but still buzzing like a pice of crap.


what the **** is up with it?

[davegttph1]

surely the buzzer is a relay, maybe its knackered? replace it or just take it out permenantly and leave it out:)

[MillSpeed]

Might be the low water sender going bad i.e. the one on the front of the filler neck about 6 inches down from the cap.

[Oedipus Rex]

thats what I thought, all looked pretty well intact though when I checked it out. I had to drive for 45mins with it going off today.

[MillSpeed]

Christ that has to be doing your nut! There was a procedure for testing it, just can\'t remember what it was. I\'d try disconnecting it to see if it either goes off constantly or stays quiet. If there\'s no change (i.e. if it still comes on intermittently) then the problem must lie elsewhere. Might be worth earthing the wire to the block or something to see if it goes off then aswell.

[Oedipus Rex]

I\'ll do that, cheers matey.

I\'ve had exactly the same problem since last Weds mate,  only I havn\'t been able to find the club website untill now, the addy must have changed from .co.uk (saved in my faves) to .com??  Thought the place had dissapeared!

Anyway, I checked the wire from the filler neck and it only controlled the temp gauge, buzzer still carried on!

Do you know where the low level sender is located, a mate says they\'re usually in the expansion bottle.

If you\'re using the car and want to shut the noise up temporarilly, do what I\'ve done.
Get your head in the drivers footwell and look up at the wiring, you\'ll see a black plastic box about 6x2" with a sticker on it. There\'s a connector block either end and one in the middle, pull the middle one out (9 pin connector I think).
That stops the bloody noise, but on the downside.......
the windows wont go down LOL!

Keep me posted if you find anything :-)

[MillSpeed]

The one with the single wire coming out of it on the front of the filler neck is the low level sensor. The temperature senders are on the back of the filler neck, tucked away out of sight underneath the boost pipe.

[Trevrx]

Ahh,  I assumed it was the temp sensor because I pulled the connector block apart that the single wire goes to under the boost pipe and that killed the temp gauge, but not the buzzer!

I\'ll strip a bit of the insulation and try earthing the single wire tomo,  that should knock out the buzzer and prove that the sensor is knackered hopefully.

Try earhing it to see if it is the level sensor as suggested.  Another possibility is:-  There is a connector under the power steering pump (single wire) that if split will make the buzzer go off continually (can only be seen from underneath!)  

When i put my engine back together my mate forgot to connect this up, and the buzzer wouldn\'t go off, obviously i thought i had an air lock in the coolant system and drained / refilled it a couple of times.

Another sensor is located next to the oil pressure sender (below oil filter).  This is a single wire again tied into the main loom.  Check that that\'s not worked its way loose either.

Cheers

have you changed the plugs recently?? strange question i know but the wire for the coolant buzzer/sensor connects the the loom down the back of the power steering and aircon pumps, its a pain to find but if its not attached then the buzzer will go off intermitantly.

Yep, thats the one...

[Trevrx]

Nice one guys!

I checked the connector behind the power steering resevoir today and sure enough the single wire was broken off (just about hanging on).

Re-connected it and all has been well since, so fingers crossed.

Good info\', thanks!

[Oedipus Rex]

mine has just stopped so I\'m just gonna pretend it never happened.

[Oedipus Rex]

aaaaghhh its back again!!!!!!!


went out, drove about 15 miles --- fine, parked her up went and did some shopping and stuff, came back got about 3 miles and



buuuuuuuuuuuuuuuuuuuuuuuuuzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzz


goddamn it, it came and went during my drive but came more than it went. Parked it up went into my restaurant, did a few tasks got back in, no buzzer, half a mile later

buuuuuuuuuuuuuuuuzzzzzzzzzzzzzzzzzzzzzzzzzzz


damnit. Parked it, waited for it to cool down fully, opened the filler neck cap, full to the brim. Checked the expansion tank, full.


I\'m proper annoyed with this now. there seems to be nothing wrong with the low level send and I\'m just lost. Don\'t want to disconnect it because I know I\'ll just forget about it and then one day I really will be low on coolant.

Sorry not really looking for help just looking to vent some frustration.
