My son just bought a 2002 Civic and it is a pretty damn nice car. Since
my daughter has a 2000 CRV I know about the Honda blue coolant. The
Civic has green coolant in it and I need to know what is the best way to
flush the evil green stuff and get the blue in the block. Where are the
drain plugs on the 2002 civic and what is recommended for flushing the
color is irrelevant - it's chemistry that matters. there are a number
of high quality non-silicate anti-freezes on the market, no two with the
same color afaict. if you /knew/ what was in there, maybe you could
there's two drain plugs - bottom right of the rad [left if you're facing
the engine] and the drain plug on the engine block. if it's a d-series,
it's a largish hex plug lower left as you face the motor. you'll need a
new gasket when replacing. and you'll need to repeat this process at
least twice - the coolant in the climate control system never drains.
one last thing - don't use tap water when refilling, use distilled.
Is the existing coolant dull, dark green or a luminous bright green?
Dull, dark green is older Honda OEM. Luminous bright green is evil
The best way to "flush"is simply to drain it all -- including pulling the
block drain. Then stick a garden hose in the rad filler neck, and spray
water in until all orifices run clear. Let it all drain, plug up the
openings, then refill with genuine Honda Type-2 premix.
