Went out to start the focus, i think the garage has just filled the rad back up with water without any antifreeze. I started the car to warm it up and could smell a burning coming from the bay area.

So knocked it off and opened the bonnet, seems the water in the pipes from the expansion tank and the rad has frozen.. Anybody got any ideas how i can get it going or will the heat from the engine just melt this OR should i not drive it while its like that?

cheers.
