Tap water or Distilled Water/Coolant Flush & Fill

[Dave]

First I would just like to say that I am new to this forum; but I have been watching Eric’s videos for awhile now. So without further adieu, I will get right to my question.

I’m the proud owner of a 94 Civic VX with 234,000 miles on the odometer and I would like to do complete flush and fill. The question is whether it’s okay or not to use a garden hose to flush out the cooling system, or if it would be best to use distilled water instead. The current argument provided on another tech site is that tap water from the garden hose can leave corrosive sediments. Are there any thoughts that would settle this debate?

I’ve only owned the car for about six months, whereas I’ve no idea if this service been done before. This is really for my own piece of mind, plus I already have a gallon of genuine Honda coolant.

Hose water is fine if you don’t have hard water. if you
do then the distilled water is the better solution.
