    Simple Question

    Hi People

    I wanna drain the coolant(and re-fill) out of my 91 3b s2.
    Is this just a simple matter of disconnecting the the pipe at the bottom of the main rad - draining - re-connecting pipe then filling back up? What about air in system?

    Cheers guys

    It only emptens the rad. You need to open the thermostat cover to get it all out. Actually it wont come all, but nearly.
    Open the bleeder bolt on the rad when refilling. Rest air will come out by itself. Usually heater matrix bleeder is useless. You might need to rev the engine a bit. Say 3000 rpm for a moment to get the water to circulate properly.
