If you are only running on the street and don't have overheating problems,
you can still use anti-freeze and not need to worry about draining the
system each winter (including the heater core).
Straight water transfers heat much more efficiently than water/AF mix, but
needs some sort of anti-corrosive additive. Water Wetter from Redline
lowers the surface tension of the water thus lessening the tendency to form
insulating air bubbles around hot spots in the head. I understand dish soap
does the same thing, though I don't know if it works as well. Water Wetter
contains an anti-corrosive -- I'm not sure that dish soap will do that.
Water Wetter is more effective with straight water than with a water/AF mix.
When I was racing, I used straight water and saw a 20 degree drop in coolant
temps with the addition of Water Wetter.
I used to get it from Racer Wholesale in Atlanta. Google should give some
places to get it.

Subject: A couple of Midget Questions
I think my wife is cheating on me with a 3 foot tall midget so I want
to know.... :-)
Seriously....
My MKIII Midget is out and about again after my clutch hydraulics
rebuild. Thanks to all who coached me through that first time
experience!
Now I have a couple new questions.
1) I still have anti-freeze in it which will come out today in favor
of plain old water. Do I use tap water (full of calcium around here)
or distilled (which I am leaning toward). Also, I recall people on
this list talking about putting some sort of wetting agent in the
water to increase it's heat transfer effeciency. What do you use and
where do you get it?
2) Clunking noises. I don't like clunking noises. They usually come
attached to $$$$.
When I engage the clutch I get a distinct, heavy "Clack" or "Clunk"
from somewhere in the butt end. There seems to be some "lash" in the
drive train, too. Or maybe it is just my imagination due to the clunk
sound. The car has wires on it - should I pull the rear wheels and
examin the splines? There is also an occasional vibration when
reaching about 30 nph and above. If I back off on the gas a few times
it smooths out and goes away for a while. U-joints?
All input gratefully received....
Cheers!!
