    Default pressurizing water in a wee 1.0 Nova

    hi there,

    i have a wee 1.0 nova she is a 1992 3 door model

    i have this problem with the water pressurizing is it normal for water to pressurize?

    i have already changed the head gasket were i thought was the problem as the water and oil were mixing but even after this the water is still pressurizing.

    has anybody got any ideas of what it could be?

    i took the thermostat out to make it stop overheating as fast cause my fan was broke but now i have a working fan again would that be the problem of the water pressurizing as i did not put the thermostat back in?

    when you say pressurise, is it literally blowing it out everywhere?? are you losing water?

    the system is meant to pressurise to a certain point anyway, but the rad cap looks after it.

    get a replacement cap for a start. did you use the heater pipe on the cylinder head to let air out after the head gasket replacement?
