Do not use tap water when prepping the antifreeze. Use Distilled water . .
.like the kind they use for steam irons. There is a reason they want
distilled water in that iron . . . it keeps the iron from plugging up with
deposits. Hot iron = hot engine.

The minerals in tap water precipitate out . . . check out the hot water
faucets in your house. Notice the lime buildup? I dont want that in my
engine or radiators. Distilled water is cheap insurance. I think it costs
the same as windshield washer fluid . . . cheaper than spring drinking
water.

I always save the Pentosin Anti-freeze containers. When I buy new A/F, I
empty half into an empty container . . then add the distilled water into
each container to the full mark. On each such container I write with magic
marker "50/50 mix". Now its all set to go, no measuring required. Also, if
you have a partially filled container . . .. 6 months down the road . . .
.you will know if its straight or 50/50.
