    Default Coolant Expansion Tank

    Had a run out today and had a leak from my expansion tank out the pressure release at the back.Nothing major and all temps were fine all the time.One thing I have noticed is when I squeeze the pipes there is air coming out of the release release valve.Should this not be closed and if so do I need a new cap.Any other ideas what this could be as I can only see problem with cap being stuck open and letting coolant out rather than only letting it out when it should if engine overheats causing to much pressure

    Had a similar issue on mine. New expansion tank from the dealers is only £20. Get a new cap as well, they're about a fiver

    Easy to fit (half hour max), but get some coolant, as you'll lose some when you change the tank!

    Best get a few hose clips too, as the original ones are a pain to refit!

    One for the bottom connection to the tank, and two smaller ones for the top two.
