 Ey up

 Driving home today, pulled up at a set of lights, steam starts issuing from under the drivers side rear of the bonnet. Got to a safe place to stop, popped the bonnet, its lost only a tiny amount of coolant - it was dribbling from the rear of the engine onto the floor.
 I couldn't see where it was leaking from, only that the drip is running down the centre rear of the engine onto the floor. Called the RAC, they turned up in under 15 minutes. He poked around, started the engine and put the heater onto hot - no warm air. Only the tiniest dribble of coolant onto the floor. He followed me home, the temp gauge (reading ~85 when I set off) dropped steadily as I drove the half-mile, high gear, low revs.

 Going to ring my mechanic for a tow to his garage in the morning, since he's all closed up now.

 Regards
Pete

Yes mate, the most common fault on the omegas heating is the hbv or vac connections to it. Have a look at the back of the plenium on the drivers side  with a tourch ans see if you can see the hbv leaking.

Yup exactly the same happened to me, although it piddled the coolant onto the coilpack while it was at it & made it run like a lemon

Part is something like £23 or £27 inc VAT on TC at vaux (can't remember exactly as I didn't actually buy & fix it...)

Cheers guys. Had a good look now I'm not risking burning my hands on the engine... leak seems to be coming from rear top left of the engine, can't see the HBV itself, but IIRC thats where its located?

 ETA: Sorry, reread the first reply, that is where it's at. Appreciate the help guys.

Regards

Yep it is.

Try turning AC off - may stop it leaking.
