diesel engine coolant color differences??
I believe it's red coolant in my cummins ISC 8.3 engine, and I believe it's green (going by memory on the colors) in my generator, Onan 7500. I carry a gallon of each, and have them marked so I won't get them mixed up. My understanding is you shouldn't mix them. My question is.....why? what's the difference in them? Thanks
