Hey all, Not to long ago I asked about changing out the antifreeze in my 763. At the time I didn't have an Operation & Maintenance Manual. I found one and was reading the section on changing the coolant and it stated the machine came with propylene glycol (purple color). It went on to say not to mix Ethylene with Propylene, why? The coolant in it now is not the factory stuff. From the looks of it, it must be Ethylene? Will it hurt to run good old Preston Ethylene? I better git I'm confusing myself. Later Bobcat.
