had a block heater already ordered, already have the studs, they are a necessity up here for about 8 months of the year. thanks for your help, 50/50 coolant is as effective at extremes as a higher mixture? seems strange but plausible. why would a wagon need more weight, it already weighs about two tons? just kidding, i keep the sand bags for weight and traction. what about tranny fluid? 4sp+o.d. Whill the regular atf be fine? haven't had any problems yet but this car does at least 800-1000 miles a week during the winter when i store the sedan because it doesn't have enough room for the winter gear. gotta love the wagon, hauls four people and all the ski gear up the mountain quite comfortably.
