It eliminates the need to run sacrificial anodes to protect aluminum components, eliminates scale build up, reduces stress/pressure on the radiator by running a non pressurized radiator cap and the coolant never needs replacing or topping up in a leak free system. Is anybody here using or had actual experience of using Evans NPG+ coolant? I was reading another thread about whether to use distilled water or not and remembered that I had planned on using Evans NPG+ because it seems to solve a variety of potential cooling system problems and seems like the way to go with an engine with rare and irreplaceable aluminum cylinder heads.
