I have a 96 6.5 td with 260k on it, and it does not like cold weather. It wont start if left outside for more than 5 hours not plugged in at 30*. I just put new glow plugs in octoberish range, and was wondering if there is something that everyone does for these trucks that i dont know? Ive had mine a year and am tired of going outside and having to worry about if my truck will start or not. It will start fine 45* and up. But lower than that, and its a no go. Any help?
