Aside from other things said here... are you the original owner? I

I mentioned the Prestone "patented Organic Acid Technology formula"
because it comes in a yellow container, according to their web site,
and that is what Bill says, that he has been using. According to the
"Real ethylene glycol" comment, maybe be wants the black container
stuff now. The (apparently) good stuff is now labelled "Prestone®
Heavy Duty Antifreeze/Coolant" and comes in one gallon black plastic
containers. "Heavy Duty" looks good to me, but still you have to
remember that everything printed on the outside of a consumer package,
is hype. I should know. I used to work for Microsoft.

By the way, if deer or other wildlife should happen to ingest any of
the ethylene glycol that leaks out of your vehicle, try giving them
beer, as an antidote. Ethylene glycol as a poison acts by being turned
into insoluble crystals in the kidneys, and thereby damaging them, or
eliminating kidney function entirely. Ethanol in beer displaces
ethylene glycol from this process, and causes it to be voided as a
liquid. If you get the beer to them early enough, you can save them.
There should be no trouble getting deer or any other woodland critters
to drink beer.

So what coolant is appropriate for a YJ (93, 4.0L)?

Not sure what people mean by 'late-model' in a jeep forum, it could be
interpreted in a variety of ways (IE disc brakes / fuel injection /
computer / cat conv / radial tires / heater / doors = late model jeep)

Sorry, I probably should have said late-r. I'm not sure what the 93
would take, but it seems what is most important is that you add what
you already have in the system. I would ASSume this is "Classic
American Green." Pouring new formula Prestone a.k.a Dexcool a.k.a OAT
in your radiator might cause problems. That .pdf paper I linked has
the details on what you should look for in the ingredients.
