I picked up a D5 hydronic heater mainly for hot water (using a heat exchanger) and cabin heat in the back but I would like to tie it into the block as well for engine preheating. Also stops me from having to add an additional reservoir/expansion chamber.
However it extremely difficult to figure out where to tap into the coolant system on the engine. Does anyone have an example of this type of hook up or coolant system diagram?
I wanted to use the following coolant thermostat so the hot water and air loop is heated first:
