How much is Honda brand antifreeze?

A simple drain and fill (meaning you leave some of the old
coolant in the engine block, but you put new coolant in the
reservoir) will require about one US gallon of either OEM
pre mixed coolant. The exact figure depends on whether your
93 Civic EX is (1) Canadian or US; (2) auto or manual. See
your owner's manual, under "Capacities" in the index, or go
to https://techinfo.honda.com/rjanisis/logon.asp for a free
online owner's manual.
Note: I think there is a typo on the capacities page (page
186). Footnote 1 should say "Excluding" not "Including."
That's "Including" is what's in my 91 Civic's manual, and
only this makes sense.

The other posts have recent price quotes.

Buying it online generally cannot be done, since shipping of
fluids to your home directly is restricted or flat-out
prohibited.

I actually have used the orange Havoline anti-freeze in my
91 Civic since 2002, and all is well. It's said on the
packaging to be good for aluminum yada engines. Some here
say OEM is the only way to go. A few of us have been
experimenting with the Havoline and are happy. Experimenting
with Prestone or anything else is a no-no, AFAIC.

would be replaced by the antifreeze/water 50/50 mix?


Did they drain the engine block water jacket? Most don't, because that drain
bolt is
a bear to break loose!

Do you know what is the ratio in that premix.???

you don't have to go completely crazy, though. like plain water is
better than leaving it dry, temporarily. the antifreezes that sell
themselves as being compatible with hondas are probably reasonably ok,
as they wouldn't want to face class action suits. and if you do dilute
it with water a bit, it's not going to destroy the engine.

me, i try to stick with the honda stuff as much as possible, but the
last time it cracked a hose, it was friday pm of course, so i had to
fix it on saturday which meant a generic hose from poop boys, and a
quart or so of whatever coolant they sold that advertised as honda
compatible to refill it; i figure that it won't destroy the engine if
i leave it in till the next coolant change. which, with the thermostat
trouble, won't be too long. of course, it could be the coolant
destoryed the thermostat in a couple of months....

yeah though, like the other guys said, if it's overheating it's more
likely more than just needs coolant. even if it does need coolant. the
radiators on theese guys are tiny and it doesn't take a lot of clog to
make them need replacement. which isn't a big deal. but if you leave
it and it continues overheating, it will spring a head gasket leak.
hopefully that's not what's happening yet.
