Robin,
only if it thaws out.
My windscreen wahser bottle has been frozen solid from last Saturday so I have been carrying a Skooshy bottle of windscreen wash/de-icer mixture around in the car with me. Its now sitting on my desk trying to thaw out. Minus 11 at the house this morning at 04-45 and dipped to minus 12.5 on the way to Glasgow. Bottle of stuff frozen solid.
Zafira also took a few extra turns to fire up this morning.
The thermal overalls have come out of hibernation as well.

Regards

Ian
