the best way to find to find this out is to go to your local checker, schucks, kragen, or murrays. the info is in the computer tell the counter person to input these numbers-- 98 (year), 32 (Honda) Then he will ask civic "cx,dx,ex,lx,vx, or si model. then tell him you want to know the coolant and amount. it doesnt matter what brand, the cheapest will work (green coolants have the same chemical breakdown, and orange have the same chemical breakdown) the only coolant to worry about is for Dodge deisels. hope this helps. Hondas are weird about their coolant. If you put a silicate-based antifreeze in a Honda you'll shorten the life of your water pump. The very safest coolant to use in a Honda is Honda Genuine coolant, which comes from Honda. The last time I bought any it was over $11 per gallon--and that's premixed 50/50. You can use the "all makes all colors" antifreeze. That's non-silicate, and it works.
green
You can use Prestone.
Dex-cool
Honda type 2 or Toyota Pink.
Your best bet is to call the dealership for a recommendation.
You probably used the wrong type of antifreeze. You should use the type for aluminum heads.
OBD2
IT uses the standard green 50/50 solution
A 1998 Dodge Neon uses green antifreeze.
If you use the Honda brand, you will not go wrong.
Was built with Dexcool. A lot of people switch to green.
What type of antifreeze do I use for a 2000 bonneville
