A couple questions for you diesel engine RVrs (Mine have been gas). How cold does it have to be before you need to pre-heat your engine, and how long do you pre-heat it before you start it?

Aquahot with an already warm boiler will only take a few minutes.
I can assure you that an AquaHot with a fully heated boiler will only take a few minutes to warm a Detroit Series 60 from below freezing to an easy start temperature. Remember that you are not warming it to operating temperature, just warm enough to start. Been there, done that on many occasions.Ned said:It will take more than a few minutes to heat up all the iron and oil in a big diesel engine block. If it's not below freezing, we usually run the block heater for a couple hours in the morning as we pack up for travel. If it's colder than that (we try to avoid those nights) we'll turn in on the night before and let it run overnight. Using the block heater this way the engine always starts just as if it were a warm summer day![]()
