Omega General Help / Coolant Drip - Help - UPDATE - Pics now !

« on: 21 September 2013, 14:38:06 »

Hi,

I have managed to take a few pics now at:  https://fluidleakomega25v6.shutterfly.com/pictures/8

Went for long drive (1hr) and no leaks.

Car sat for 2 hrs cooling down before the dribble then started.

It is not a fast dribble, and normally has stopped the next morning.  I shall test this theory today and report back.

Seems to come from under the heat shield (see pics on drivers side of the V6 exhaust manifold) and I can't trace it any further.  HVB BONE dry as are pipes around them (I just managed, at the expense of some skin on my knuckles to pop the temp sensor wire back    - thanks for the tip - Could of done with a gynecologist to put the wire back  ).

The ofending fluid perhaps feels a little viscous/oily than watery, and more green but jury out until I have my sample later.

I have left a clean container under the car so will collect sample and compare to my coolant sample (which I can confirm is a blue/tourquoise colour).

The leak in question I thought was more greenish (but the garage floor is painted grey !!!!).

Once I get a sample from my strategically placed container I shall compare the fluids and report back 

I'll keep posted.

Andy.

Temp guage did work, but not ran engine since I had a "feel around back" of the engine 

Thanks for the pic - I'll have another feel later now I see where it may have come from :-)

Sorry - The spade connector is sitting on the end of a single wire, originating from the back NS behind all the pipes at back, and is sitting near the HBV looking at me all homeless with nothing connected to it ?

Not checked coolant colour yet (later when get home  )

HOWEVER

I noticed when looking at the HBV again that there is small wire (spade connector on the with black plastic shrowd) not connected to anything.

Plastic shrowd has a small chip on it, but should this be connected to anything ?

Have a knocked it when feeling  the HBV

Is there any pics of the back of the engine I could perhaps see to ascertain where it may plug onto (I can't feel an obvious terminal for it to plug back onto)

Cheers,
Andy,

Just been for a lay down under the car as it's dripping now;-)

Coolant is definitely Green.

Appears to run down what I assume is bell housing, by starter motor.

I have put hands around the HBV and all dry !

I have  few pics I shall try to post.

If oil cooler, guess this is more difficult job ?

Daft question, but given the Leaking fluid when I saw it was Green, I assume this is the OLD coolant as I see people mention red or blue, with red the new stuff.

Fantastic - thanks for the coolant link.  As mine is a V6, I may top up once it runs clear with antifreeze straight as I gather this will give me the correct 50/50 mix.

One final query - it mentions "burping" the hoses ?  Is this squeezing the rad hoses when engine running ? And is there a particular to focus the "burping" :-)

Thanks again in advance.
Andy.

Just run car up to temp (with heater on hi for a bit and then low) and no sign of coolant  drips from the HBV  or under car ?

I'll leave overnight, but maybe that it only leaks a short amount when it cools down ?

Tried to find the link of how to drain and refill the coolant, but not much luck :-(

Hummmmm

Many thanks.

The guide looks fairly simple (last words !) so I may give it a go myself.

I assume if I am carefull I can use the same hoses so not need to get anything extra other than new HBV (from Vauxhall) and antifreeze.

Any recommendations on antifreeze (ratios) and refilling process/proceedures when its been drained to prevent airlocks ?

I have not had the cam belt and tensioner done for a while, so I am perhaps talking myself into getting a good local independent to do both ?

thanks all,
Andy.

Hi,
I have just noticed a small coolant leak on my omega (2.5V6 CDX – V plate – 59k on clock – owned from new).
It appears to leave a small (probably a couple of teaspoons full) of green coolant/water under the car when parked. 

It appears to have trickled down and drips off the two bolts at the bottom of the gearbox/cluctch ? (two small torx bolt heads stick straight down) right in the middle just behind the front wheels.
I suspect its originating from higher toward the back of the engine (at the back) and working its way down.  I perhaps noticed a little of green water resudue on the bottom of the AC compressor (more towards passenger side) but the drip ends up coming off the two bolts I mentioned.

I have read there are some pipes to watch out for at the back of the engine bay ?
I only do about 1000 miles a year, and probably only use it once a week so not sure if that has lead to the problems but my journey is about 10 miles so all up to temp.
I was looking to see if anybody knew of a good independent garage in the Chester / Wirral area ?

Thanks in advance.
Andy.
