    Coolant Change

    I changed the coolant on my coupe turbo, before i changed it, coolant flowed constantly back into the header tank through both the pipes on top of the tank. Since i've changed it coolant only flows back into the header tank through the back pipe. Is this normal???

    It should flow through the pipe on the side of the bottle! The bottom pipe is for the Aux waterpump! it curcilates when the engine is switched off

    Have you bled the system properly chap? Maybe there's still a slight airlock in the system

    while its running squeeze the radiator pipes whilst the header tank cap is OFF. it can help remove any air locks.

    As above really, or just leave the car running with the cap off for 20 mins or so
