Several people here report that the orange Havoline Dexcool
works just fine. I have used Havoline Dexcool in my 91 Civic
since late 2002.

Not sure if there's much difference in price, though.
Probably less than $20. So if you don't mind driving to the
dealer's to buy the stuff, it's arguably your safest bet.

The bearings of the water pump don't do well with other
coolants.

orange dexcool is fine. but dilute with distilled water, /not/ tap
water.  tap water has minerals that will ruin seals on the parts that
move and corrode and clog the parts that don't.

Non-"Silicated".

Silicated antifreeze is the cloudy stuff.

Genuine Honda premix would be advisable, but more important is to make sure
you've *completely* got rid of whatever murk is in there now, and that
means pulling the block drain as well as the rad drain.

Mixing different antifreezes will likely destroy the Long Life additive
package in the new stuff, as you've surely got no idea what's in there now.

Stick a garden hose in the rad filler neck and let it run until the block
and rad both run clear. Let drain, close taps, then refill with your
selected poison and DISTILLED water. NEVER tap water. If you use Honda
premix, it's added straight, not diluted.
