As for the cold starting....I'm going to add a blockheater (hopefully) to mine for this winter to make sure I can get it started easily.....mines generally fine down even to -5 to -8 or so, but it was -12 and I had a semi-weak battery so I stood no chance. Once I poured hot water over the block for a few minutes with a new battery I was good to go

Our 83 started when it was 7 degrees in Mackinac City waaay up north with 2 glow plugs working....after over 50 seconds of continuous cranking!! We were rooting for it....it was like a scene from "Das Boat"
