My 1994 Camry came with old green antifreeze from the factory.
"I would be willing to bet that the factory fill coolant in your 1994 Camry was green Japanese coolant made by CCI (the Japanese company that makes nearly all of the OEM coolants for Japanese manufacturers). CCI has a US subsidiary in Illinois named Intac.
At any rate, the chemistry of 1994 vintage CCI coolant is much closer to modern HOAT coolants (according to the MSDS sheets I have read) than it is to traditional North American green coolant, which is anathema to Japanese automotive engineers because it has the wrong pH for aluminum engine blocks and it is full of abrasive silicates.
Don't confuse Japanese OEM coolant with traditional North American coolant merely because it happens to be green."
more interesting info ^.. that's probably why my 1J had Green in it when it was received. This thread also states that the factory Camry owner's manual says to only use 'Ethylene Glycol' based coolant.
another:
I just got back from the store and normal Prestone (the stuff that you mix for $9 gallon) has no silicates either.
