Hi - this should be very obvious I know. But the plug on my 55 reg 2.2 petrol seems to turn through 90 degrees, but no coolant is coming out of the `spout'.
Is it 1/4 turn, and/or does it pull out ? Or just unscrew ?
Plug is about 13-15 mm diameter, with a raised `rib' across the centre of it.
Don't want to wreck the rad !
