Reason I ask is because back in the day we always used any coolant that was green for Hondas and now I mostly see blue color coolant/antifreeze. Just wondering if blue coolant/antifreeze is appropriate for the older Hondas.
That will get some universal junk with 2-EHA which I’d be concerned to run in something this old. Engine may be perfect but seals do age.Whatever is cheapest at WalMart.
That's the way I see it. It probably ran a silicate IAT green back then.1991 is old enough to be IAT green originally, at least my '89 & '90 Civics were.
