Silicate free antifreeze: A necessity for long water pump life
Written by dndgentili on 10/2/2010 at 05:04 pm


Yes, Skye, SILICATES ARE BAD!!

If you're cheap like PC**** and me ;-) you'll like Dex Cool --
http://www.havoline.com/products/na/antifreeze.html. It is silicate-free, too.
You can use it in your autos, trucks, and cycles!

But, as you said, $10, buying it from Honda, is cheap insurance plus there is no
mixing necessary.

YMMV,
VA Dan

Unless I was misinformed by Honda when I worked for them the OEM antifreeze did
