Do not add Prestone. You risk an early water pump failure
with it.

OEM is something like twice as much.

Your owner's manual will tell you the 95 Civic is due for a
coolant flush every every 2 years or 45k miles, whichever
comes first.

Re adding distilled water in a pinch: The more you have to
add, the greater the risk of improper cooling or breaking
something. The lower temperatures are when you add distilled
water, the greater the risk.

I am doubtful adding coolant will remedy the problem. Is the
thermostat original? Maybe time for a replacement if adding
coolant does not remedy the problem.

Every overheating incident brings your engine's head gasket
closer to failure in the future. I would not drive until the
correct amount of coolant is in place and/or other checks
are done.

there are many causes of engine overheating.

cooling system
- low coolant level, check both radiator and the reservoir.
- air in the cooling system. bubbles come out of the bleeding taps if
air is trapped in the system.
- fauty radiator fan: does it come on?
- stuck closed thermostat: does the upper hose ever get hot?
- faulty radiator cap: does the overflow tube get hot easily?
- faulty water pump: leave the cap off, does the coolant flow when
engine is running?
- blocked passages: same as above

drivetrain
- chambers detonation: (incorrect timing, incorrect spark plugs heat
range, mixture too lean) is there any audible pinging or rattling
under load?
- transmission overheating: (automatic trans) does the trans up/down
shift properly? does the torque converter lockup work?

if you live in the south, it's OK to fill it up with distilled water
(works for aluminum blocks & heads). i would prefer anti-freeze
because of its higher boiling point. In my Honda used PEAK LongLife
premixed 50/50, silicate-free, amber color, and added a bottle of
HyperLube super coolant as a surfactant, anti-foaming agent. They are
cheap and available at most parts stores

oh and dont overlook the radiator cap, one with a weakened spring will
lower the coolant boiling point. It's bad, cause when the coolant is
boiling, it's telling the egnine that "that's it, i can't take it no
more!!!". replaced with OEM only!!!

cheers

Honda coolant is sold in gallon jugs, but it's premixed already (no need
to add water). At my dealer it's about $13 a gallon.

when all else is good, but the gauge tends to climb towards the H
mark, then the radiator cap is the top suspect.
in this case, i would also check the temp gauge sender (next to the
temp sensor) to make sure it's working right and doesn't send garbage
to the gauge!

i have no idea. some folks say it's green in color, some say blue. i'm
only sure it contains organic rust inhibitor instead of silicate,
which tends to form gel and has adverse effects the on water pump
seal, as mentioned by other folks here

My local Honda dealer now offers a coolant system service for $49 that
includes drain & refill (not flush) with Honda coolant, radiator cap
inspection, temp gauge operation inspection and water pump noise and
leaks checking. That sounds reasonable, yes? But the problem is that
they will probably try to talk you into replacing all of those parts
and while you're at it, why not the timing belt too.. haha. If you can
find similar deals, just make sure that what's got to be done is
neccessary..

last June, i read an article about a roundup of various brands of
additives. Hyper-Lube Super Coolant is among the top, tested on a
Civic
you can google for "cooling system additives" , it appears on
turbomagazine.com

i drained the coolant by the amount of the bottle and added it to the
radiator.

Honda dealers should have them, but often not in stock, they have to
order. You can order them yourself from a few sites that sell OEM
honda parts

http://www.hondapartscheap.com is one of those

I can only speak to Accords which take around 5 quarts of coolant
total for service. That means 2-1/2 quarts of antifreeze. I just had
the 60,000 mile service on our Accord at the dealer, and draining and
filling the radiator cost $17.44 for the Honda antifreeze plus labor.
Figure somewhere around there.

If you need coolant, you have a worse problem: There is a leak
someplace, like the water pump. While you're replacing the water pump,
you might as well replace the timing belt if it is due.

If there isn't a coolant leak, you need to diagnose the problem causing
the overheating, like a bad water pump or thermostat.

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.

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