Core plug leak - serious or not?

I noticed some coolant leakage around the block. After researching the matter it seems to be one of the core / freeze plugs. I spotted the leak whilst I was carrying out a repair to a blowing exhaust on my 1.7 KY. I needed to do this repair to get through the MOT :D .

There is a fair amount of crystallised build up around the plug in question and small seepage of the green fluid.

My question is if it easy to change the plug and do I need any special tools. Secondly are the plugs easy to get hold of.

Thanks for your help.

Normally the rot from the inside or just generally become thin.

If you stabbed it with a screwdriver it may even go through (happened to me
Before)

However they are quite easy to replace and only cost a few quid each.

I got mine from eurocarparts, I think all VW blocks of the time are the same using 52 ish mm core plugs. If ours is a diesel that is.

You just need a hammer and a drift of some kind I.e large socket.

Cheers

Hi sirrocotune, thanks for answering my question.

Now, this might be a really stupid question, but do you need to drain the coolant system first?
