My Peugeot 406 V reg is leaking water from the engine near the sparkplug. It look like a rusty and coroded coldplug. Can I change this myself?

I you can see the "COREPLUG",then yeah,they are a breeze.Just punch a screwdriver through the center and lever it out without damaging surrounding metal.Clean out the core recces of any junk and using a suitablly sized socket tap the new one in.Personally,if I;ve any doubts,I smear some red heamatite,or any hardening instant gasket round the new coreplug before fitting.Dont forget to refill with antifreez,The lack of it is what caused you'r problem in the first place.
