I've noticed a small leak at the top of my radiator - its actually at one side (the left if you were sat inside the car) and is coming from a small round black plastic part which looks like it just screws on?

Theres the sound of air escaping and a small dribble of coolant coming from it when I stop the car.

Anyone know which bit I mean? Can I just tighten it up?

yeah the filler plug...allows the air to escape when filling..

has a small o ring on it..might just tighten up though..

While yer there....open the coolant bottle cap (not when hot!) and then open the bleed valve. If you hear hissing then that's air coming out. Bleed it till coolant comes out and all the bubbles stop, then tighten it up again and top up coolant.

I only say this as you say you heard hissing which suggests your rad needs bleeding of air :)

Yeah, I'll do that thanks Wobba. I'm pretty sure theres an air leak in there since the matrix was changed.
