In the North East...when temp's can reach -20...and they have recently.. Replace with Aircraft Hydralic Fluid...same as the airplanes use.  Also be sure to add some additives to your fuel tank if a dieseal.  Might also want to drain air tank-lines once in a while as they will get condensation and freeze up.  Don't forget to check you antifreeze-should be -45, charge up the batteries, have good tire thread, also if diesel engine--plug it in a nights.
Basic winterizing the vehicle !!....Be Safe
