I'm sure this has been a hundred times before but........
I'm using a lot of coolant every so often. Did two trips across town yesterday & the expansion tank was almost empty, similar trip today & haven't used any.
No obvious signs of a leak & it's running at normal temp?

check usual suspect - HBV. And get under the car, and look for leaks / drips down the passenger side of the bellhousing.
Can you fit your hands in the HBV area? ::) ::) ;D

Hhmm, I'll give it a try.
I've looked under the car from the front with the engine running (& not) & have seen one drop from the passenger side near the wheel but with all the rain recently I've not been able to see anything more.....

Mysterious loss of coolant is most likely to be oil cooler plate seal.
Take plenum and inlet bridge off, exect to see signs of coolant.
-
I think the Oil Cooler Plate was the problem with mine, when I had got everything stripped off i could see water around the edge of the plate, not as much to be honest as i thought there would be, suppose it evaporates.. but then you need to remove the Plate from the Cooler in order to get out the Plate... so do you fit a new oil cooler whilst your there?? even though the old cooler didn't look to bad I did change it was £95 from Vauxhall without TC.. Also the coolant bridge seals are only pence :y

Intermittent, but large amounts of coolant loss, in my experience, is HBV (drivers side Bo Bo ;)). Leaking stats and cooler plates tend to be far from intermittent.....

Would this be more obvious with the engine running or not and/or heating on/off?
-
No direct experience but, from memory of posts on here, yes to whether the heater is on/off.....
-
I would say HBV as its intermittent so will depend on what the climate is trying to do with the bypass valve.

Sometimes they seem to leak when set to HI, others seem to fail when set to LO, so try both settings...

Hi,my dad had a similar problem with his Omega v6,what i found was the pipe from the HBV to coolant bridge had perished and got a small hole in...also worth a look....HTH....regards...Wayne

Well I drove to work this morning with no dramas. Driving back I pulled up at some traffic lights & there was what looked like faint smoke coming from the driver’s side of the bonnet at the top :o
I thought maybe the cam cover was leaking again (but JamesV6CDX changed that a few weeks ago so I thought it can’t be) anyway I pulled over & popped the bonnet, there was no smell of oil so it must have been steam & there was coolant pishing from the HBV.
So I took a detour via Vx & picked up a "Starship Enterprise" & 5ltrs of coolant & the "nice parts man" gave me 2ltrs of water to get me home! :-?
Now I've had a look & can see the little darling but I'm gonna struggle getting to it ::)
-
You need that famous Omega service tool.
A Tunnie. ;D

Remove the wipers & plastic scuttle and you have more room to work in.

I'd lend you the apprentice but he's off school with flu, he changed mine.

Yep, I'll give it a go on Sat (got use of the g/f's car til next week) but you know what I'm like with those hose clips when we did my cambelt ::)
-
Couldn't you just scrap em and replace with jubilee clips if you find em easier?
As long as you can get a driver on to tighten em up I don't see a problem.

That has crossed my mind, I'll see when I've got the scuttle off....

Or bribe a friendly student to do it for you. :y

Jubilee clips are easier to put back on, if you need a hand, or rather a smaller hand than yours send me a PM ;)
