    Okay so went for a bit of a drive today after work
    Friend pointed out that i lost a bit of coolant from my overflow, checked hoses and radiator. All seemed fine
    Driving along and i noticed my heater wasnt getting as warm as usual, checked radiator hoses again, no pressure.

    Thinking maybe thermostat but ive just done inlet manifold gasket and put a brand new high flow thermostat in only a month ago.
    Also thinking maybe air pockets, dont think its been bled properly

    Probably just the radiator cap not sealing.

    Means the system doesn't pressurise and the coolant expands and dumps out the overflow.

    Get a new cap, cheap as chips.

    Could be the issue, old man was adamant on me getting a new cap but a lower pressure one.. might go get my old one back see if that fixes the issue
