Question

I want to use the Carioca 644 to drive to the alps for skiing, park it outside possibly -20C, while we live in an appartment, then drive back, please advise on water drain down.

Answer

There will be drain points around the van, open all these and open all the taps. It is a good idea to blow down the taps to make sure there is no water left inside them, also drain any strainers connected to the water pump
