    Pretty hard to read that lol.

    But it sounds like you haven't bled it properly so have a airlock somewhere.

    Also the RADWELD / K-stop etc is shit - so wouldn't use that again

    To fill / bleed you should -

    Cut bottom off a 2 litre bottle
    get a bucket / watering can full of water
    open the 3 bleed valves
    Place hand over the lid of the cut bottle and fill with water
    Put the cut 2 litre bottle in the rad
    Keep filling it with the watering can / bucket (so there is always water in the cut bottle)
    Wait until water comes out of all 3 bleed valves - let it run through for 5-10 secs
    Close valves
    top up with anti freeze

    This makes sure no air can get into the system - as it's always water whats going into the tank - no air.

    Simple job but easy to get wrong.

    The K-seal that you used will eventually bung your heater matrix up,so as above to a good idea mate.

    it will tick over fine as its not under anyload ...

    if you want a quick dirty fix just to make it drivable turn the heating up full as you drive around and open your windows

    having the heating on take heat from the engine and puts it in the car ...
