Review on 🌡️ Enhance Engine Cooling with Design Engineering 040104 Radiator Relief Coolant Additive, 32 oz. by Jim Roberts

I used it in my baseboard heating system! The return temperature dropped by 5 degrees from 60 degrees (from 180 to 120) to 65 degrees (from 180 to 115). That tells me an extra 5 degrees was radiated to heat the house! not just back in the oven. It also reduced kiln run time. This is due to better heat transfer in the boiler from the furnace to the water jacket!
