Corsa C coolant hose mystery

Wig

started taking it out with a thin screwdriver blade hammered down into it, it chewed up and basically I'm digging out softish plastic.

I'm getting a bit nervous because I would rather have a special needle nosed picking tool, and an M8 tap to clean out the thread both of which I have at a different address. I don't want to dig too much/anymore at this address as I may not have any success or may damage the thread and will probably be unable to replug the hole with the screw to allow me to drive the car. So I stopped working & refitted the screw. Drove to get LPG filled to test the screw is still water tight - it is.

Will have another go tomorrow with the better tools.

Glad you Sorted it!

Are they the same Internal Diameter?

Yes, both the same internal diameter - 2mm

The last two pictures here:

show the top bit can be removed away from the water pump house. I think I'll do that as it will be easier to work on and won't get bits of plastic dropping into the water pump and then fit a new gasket.
I may have to fit the old gasket back on with a bit of silcone for now if I can't get a new gasket.

But this should make the whole job a lot easier, and pretty much guaranteed to be a success.

I guess those two top bolts will be something like 8Nm?

Going to France on the ferry tonight.....:eek:

I used to be a member of that forum.

Vauxhall doesn't sell the replacement gasket, it is shown on the diagram but they don't do it.

Then I discovered that on my engine there is no removable plate (as shown in those pictures） anyway！！！

So I started with an easyout but it just squished the plastic up instead of turning it out. So I started to pick it out with a needle, and try to stop bits from falling inside. I think quite a few crumbs went inside and possibly the big end bit may have fallen off. hopefully not going to cause any problems later on.

Then I cleaned it out with the M8 tap and that removed what was remaining.

£10 bit went straight in with a bit of gasket seal just to be sure.

Fingers crossed we're off to France.
