Good on ya for thinking about this in advance of the snow flying.... of course, now you've jinxed us. FWIW...here's my winter prep checklist when I'm facing my first winter with a new diesel:1) fresh glow plugs, wired to a solid 12V using a starter solenoid2) Mobil 1 synthetic diesel-rated 0W40 oil... nice and thin for the winter, nice and thick during the couple days of summer3) biggest battery I can jam under the hood... 650 CCA at least4) block heater... 400-600 watts5) timing bang on6) coolant checked for freezing point... replaced if dubious7) compression test if I'm in doubt. No amount of add-ons will help a diesel with low compression in the dead of winter For added safety... I'm a big fan of a 1-2 amp trickle charger under the hood... attached to the same plug as the block heater. Tops up the battery and warms it at the same time. Canadian Tire has 'em on sale all the time for less than 20 bucks, as does Princess Auto.just some random thoughts,Vince
Also maybe some booster cables and good fortune\luck\karma - just in case.....................
