- well, the heater in my Diesel heats the coolant and block to right around 160F,
- plenty warm enough for sub-zero starts (-25 to -30 F, around here at times)...
- of course, state of tune and general condition of the engine and starting
- system have much influence, too... my 359cid Diesel *will* start unplugged
- down to -20F, because I'm meticulous about its condition...

- if that's all it's getting to you either need a bigger heater or need to leave
- it plugged longer...
