does anyone use a engine heater? i was in wyoming (-25*) & my disco froze. where can i get 1 & how much $ r they????

 

What do you mean it froze? Wouldn't t turn over, when did you last change your coolant, is your battery old and unable to turn the engine over or did you break your block? I live in Colo and we have had a good cold snap and I didn't have a problem.
Your can buy a block heater thru the dealer or you may find an aftermarket one thru the parts store.
