I thought antifreeze never really goes bad just gets contaminated? You can actually let it sit in jugs and the containments of dirt etc will separate. Naturally some contaminates can not separate. I just stating that it really dosent expire. Most of the time the debris settles out and you can see this in clear containers. Granted it's pretty reasonable to just buy new coolant.
