<VV> Re: cleaning oil cooler

[Kirby Smith]

The simplist way to (at least partially) clean the oil cooler may be 
with brake cleaner, but it probably won't remove lacquer and carbon 
build up.  Carburator parts cleaner made with chrysolic [sp?] acid will 
be more thorough.  It will discolor aluminum a bit if your part isn't in 
deep enough to be well under the water seal used to keep the acid from 
evaporating.

Use eye and hand protection.  Just as hydrofluoric acis reduces glass, 
and nitric/sulfuric acid mix disolves gold, chrysolic acid disessambles 
organic material, which includes you.
