Supercorsa Leaky Tyre Valve. How Do I Change?

Is changing a schrader tyre valve on a super Corsa the same as any other? Mine is leaking. I've seen videos for car tyres and assume it's the same.

Any links to kits would be appreciated. Thanks

 

Thanks. I've found kits online. A trip to halfords it seems.

 

That's where the air is coming from so certainly seems like the case fingers crossed.

 

This is the issue, it is the core inside the valve. I purchased a core remover from Halfords, but i doesn't have the pull to be able to lift the core out so have another tool on order that should.

 

I gathered as much, but the core just keeps turning and the tool won't lift it out. Maybe I'm doing it wrong. Just an annoying little thing to do wrong

 

My god. I'm dumb. I've been doing it with this valve on the bottom. I'll try it up top. Thanks for the advice

 

OK I fixed it. I just turned the valve core tighter and it has stopped leaking!
