Need a bit of advice about dad's omega. He's taken it to have the headlights polished and the air con checked. They pressure tested the air con system and found it is leaking at one of the valves.
It's the valve circled in the picture below



There appears to be no valve inside the port. Just a ball cock. How easy is the valve to replace?

Very. 

Takes 30 seconds, and regardless of what anyone says, the valve insert is available separately for less than a fiver... if garage wants to fit a new pipe then they should do so free of charge and they should pay for the pipe too as it's unnecessary to buy the complete pipe

I was told by countless people that it was the whole pipe until I removed it to show thhem what i wanted. Andy C provided me with a part number while I was stood in my local Vauxhall dealer that had just told me the same as everyone else

The valve you require is readily available from gm, it's called (high pressure valve), the one above it too the left is the (low pressure) and a normal tyre core will do, the switch in the top right is pressure switch, about £60.

There is a guide in the relevant section, of how to change said valves and the gm part numbers.

You need a 17 mm spanner to support the fitting under neath while you use a 15mm socket in the valve itself (ask The Boy  ). The 15mm will be a tap on fit

If weere bothtalking the same valve, mine was about £5

That is the high pressure switch, just visible, with two wires going to it, the valve circled is indeed about £5.00. Hp valve

So the part circled is the high pressure port and not the low pressure?
Either way will only cost a few quid to fix?
How do you put the valve in?

Sweet. Thank you all very much. It's odd that his car appears to have absolutely no valve in it at all at the moment

it's just a spring loaded ball ... very basic valve

Ah ok. The ball still appears to be there but the air is pissing out past it. Is that the valve that's goosed or something else?

The hp valve can be cleaned, with carb cleaner. But tin of that costs'. £3.00, new valve is only £5.00

[Jazzyj123]

I've already got some carb cleaner. Could it just be dirt caught in it then?
I guess it still needs removing for cleaning?
