[Fot] Liners and Alum rad cleaner

[Joe Boruch]

Until last year I had been using Distilled water in my cooling system and the
water was always rusty when I drained the system.  Last year I used tap water
(city water) and when I drained it in the fall the water was clear.  I have
seen discussions on other racer forums not to use distilled water.  With all
the different metals and corrosion cells the distilled water draws ions out (I
forget the exact chemistry) and thus draws iron out.  Using non-distilled
water with various ions in it is not as chemically active and results in less
corrosion.  Joe(B

I have started the disassembly of the TR3 to determine what went wrong in
May at ECR.  Last night after removing the radiator, I flushed it with the
garden hose and found enough rust particles to cover the bottom of a jam
jar.  I use an aluminum radiator so my thinking right now is that these
particles must be from the liners.  The radiator also has a coating of oily
gunk presumable from one of my head gasket failures in past race weekends.
So I have two questions for the group:



1)       What is a good chemical treatment for flushing oily residue from
the alum radiator?

2)      Who are the current sources for good quality liners?



I am sure I'll have more questions once I pull and disassemble the engine.



Thanks,



Greg
