Re: square pockets below the internal water pipe

["Dave Swingle" <swingle@xxxx>]

I don't think I'd like that idea at all. Anti-freeze when constantly 
exposed to air gets very corrosive to aluminum - that's why your 
coolant pipes rot thru from the outside in, in the area just outside 
of the hose clamps, i.e. between the clamp and the outside end of the 
rubber tubing. 

My guess is that the engines that have rotted thru in that spot had 
cooling system leaks in that area that went unrepaired for a long 
time. I think the silicone thing may have similar issues, eventually 
trapping water and coolant in that area. Best thing is probably just 
to get in there, clean it up, and paint it with POR15, high-temp 
epoxy, or some similar high-quality, high temperature paint.
