    Apologise for one last question on this subject.
    The car is going in Monday to have the head gasket replaced.
    I have a problem with the cooling system reaching a high pressure so have
    slacked back the rec cap.
    I want to use the car for one last journey this Saturday but it involves
    about 200 miles driving round trip.
    If I do the trip with no cap on the res what will be the result / problem.
    I don't want to put the cap on slack in case it comes of but if that is the
    best option then that is what I will have to do.
    I don't have a problem in taking the car I just don't want the cooling
    system to get over pressured and blow the rad or a hose.

    A few years ago, my head gasket failed, and it blew a heater hose,
    leaving me stranded, so you are wise to do this.

    If it was me, I'd loosen the cap just enough to relieve the pressure,
    half a turn from tight, maybe. If you are worried that the cap may
    drop off, perhaps tape it on.

    Try and keep the speed down to maybe 50-55 mph, and stop every hour to
    check the water level, as you are likely to lose some.
