Hello, brand new here and I have a question already ! I have a B7610 Hydro that I recently installed a Curtis soft side cab on a few days ago. I purchased a AquaHot cab heater. After doing some research on the web Im finding two primary locations to tap antifreeze. A T-fitting off the lower radiator hose and the water pump by-pass loop. The drain hose for the radiator runs from the block into the bottom of the radiator with a white plastic drain valve in the middle. Does anyone know if I could tie the AquaHot diverter block into that drain hose ? I would assume there has to be a flow of antifreeze going through it if it has a drain valve mounted on it and it comes from the block to the radiator. Tapping into the the lower hose is going to be quite a challenge due to the lack of space. I also paid a good penny for this fancy diverter block that came with the kit, Id like to be able to use it. Any info would be appreciated !!! Thanks..
