Its a strange world,today its close to 50f with bright sun shine and clear blue sky"s, Last week it was Minus 40, plus wind chill. On a road trip last October it got down to 0f over nite, my Crossfire started in the morning without any problem.As the engine is built in europe and sold around the world I would guess thet it is fitted with frost plugs in the block, I think that the Scandanavian countries would require block heaters,and up here its a gimmy.I have installed in-line circulating heaters to rad hoses, also a quartz light under the oil pan will work, and I have heard of Habachi portable BBQ's being used, in the bush. NO OIL or GAS leaks if you try that one,
