It seems , from the small cloud of escaping steam, and the minor drip, that the Mv6 has a bloody coolant leak.....  no advisory on it from MOT this morning....   

anyone local available to give me a hand finding it and fixing it in the next day or so ?

[MaxV6]

it appears to be on the driver side,  at the back of the engine bay somewhere.....    so any pointers would be appreciated.

An MOT won't pick up coolant leaks ....... why would it? 

Driver's side, back of the block? ............ HBV almost every time  Bite the bullet & buy from Vauxhall ~ £35 + a box of Elastoplast - not difficult, just a all ache to fit.

Sounds like HBV 

[tigers_gonads]

............ or the curly pipe at the back 

Either way, pull the wipers and scuttle off ( you can see more and use less plasters  )  and have a look 

[MaxV6]

will do,    I changed the HBV a week or two ago.....  it's done about 100 miles since....

Could be the pipe, easy to damage the pipe when replacing the HBV especially if you have ever had an oil cooler failure.

Genuine?

[MaxV6]

probably not knowing my luck....   


i would deeply appreciate a look from someone who has more of a clue ,     feeling around the HBV seems dry,    but i may be missing it....   i've had the wipers and scuttle off,  and tried to get a look in with an admittedly rubbish torch....  and a bit of a feel about.... 

i can see slight coolant pooling on the seam ridge below the heater connection pipes....   am i right in thinking the lower of these is the "curly" pipe referred to above ??

again,  the joint feels dry i think....  but my hands and specifically fingers are rather calloused and thanks to the nerve pressure in my neck,   it's difficult to feel anything with any certainty.... 


there seems to be a bit of broken green plastic clip on the top pipe to/from the heater,  but no real evidence of leakage from there...

put the heater on cold, or hot..

They put it down as an advisory on my last Omega

They can do that but can't fail it for a coolant leak

Are you in a rush Max? Happy to take a look,  next time we're up Brackley way. But that's not likely for at least a fortnight.

Green clip is usually loose, that's normal.

i'd quite like to be able to get to work really......    kind of need the money......   

[MaxV6]

but thanks for the offer.....  I found a leak this afternoon,    A leak, don't know if it's THE leak.

it turns out that the leak is only obviously visible once the cars been up to temperature and thermostat is fully open and so on....   

top connector to heater matrix , there's a broken bit of plastic on the joint with the metal pipe...  i spotted this earlier, but couldn't detect a leak,   but when it's fully up to temperature and it's had about a 6-7 mile run,  and it's DAYLIGHT  it's dead obvious....
