Hi, I have a cooling system leak coming from a plastic cylindrical unit at the back of the engine on o/s of my V6 it is leaking from the body of this unit as though it has a hole in it. It is very difficult to see how many hoses are attatched to it. Please can you tell me what this unit is and why should it be leaking from its body.
Thanks Mike.

Sounds like the HBV (Heater Bypass Valve) mate, around £30-£35 from Vauxhall

There should be three pipes coming off it if I remember correctly. You could do with getting it fixed as soon as you can as leaving it will only cause more problems, rusting and damaging your dispack (the old distributor) if you don't

be carefull of where the plastic vacuum pipes are T'd off from the brake servo non-return valve .... they're easily snapped off (and goo 'uns are not always easy to find in the scrap yard )

Not if you remove the scuttle panel

I've only ever removed the scuttle panel, is it even possible without doing so?

You can do it without removing the scuttle panel but is a bit of a squeeze..

but the point being ... is that the T's get brittle & are easily broken due to living under a hot bonnet.

Put your dummy back in Andy lad

I would advise Mike T to remove the scuttle panel so there is easy access, this way you should not break any T pieces
