i have a 2002 1.6 8v astra estate. do anyone know how much antifreeze i need? and what is the best way to drain the system?
is there anything i should check afterwards for say air blocks? what about the heater ?
Mkae sure it is cold !
Premix it in a bucket, as per the instructions on the bottle - leave heater controls on hot, empty at lowest point (usually at the bottom of the radiator). Fill up again till it's at the right level, and if there are any bleed points use them. Run and check for leaks, let cool and recheck levels. Should be it (I probably missed something someone else will pick up on)
