Hmmm. I always thought, what the hell, antifreeze is antifreeze. On the short term, thats probably right. Its made up mostly of ethyl glycol, with about 5 percent additives. Its that 5 percent that makes the difference as far as what kind of anti-corrosive properties the coolant will have. Different types break down at different rates and will protect against different corrosive factors. I bought a new Ford in '03 and took it to one of those speedy lube places one time. They told me that it needed new coolant and that the system was rusted and needed service. They didn't realize that Ford had switched to a different coolant that is orange, not green. Diesel coolants tend to be a different viscosity, and can have seals made from different materials and different parts altogether. While you may not be doing short term damage, in the long term, you probably are if you are using auto coolant. I would recommend using what the manufacturer says to use, or at least a high grade diesel automotive one.
Oh yeah, and use distilled water.
