[DML] Re: NEW DELOREAN Stainless Steel Coolant Pipes all 10 Pieces

Lawrence - This is a very sensible idea, but I want to point out an 
issue that can arise from this change if routine maintenance is not 
performed in a timely fashion on cars so equipped.  First off, we have 
been dealing with pitted and corroded aluminum pipes every day since 
our shop opened, so I totally understand the basic issue.  Stainless 
steel and aluminum are several classes away from each other on the 
Galvanic scale.  Regular carbon steel and aluminum are nearly next door 
neighbors on that scale.  If the aluminum pipes are replaced with 
stainless steel, and the coolant is not flushed and changed every two 
years (max), the remaining aluminum in the system will become 
sacrificial (anodic) to the stainless steel.  In other words, material 
will start to erode from the engine block, heads, and other aluminum 
components that contact the coolant.  Some will pipe up (pun intended) 
and say that the stainless header bottles must therefore be a bad 
idea.  The fact is that the amount of stainless steel has alot to do 
with the rate at which the aluminum will erode.  The stainless header 
bottles will not contibute greatly to the problem with proper 
maintenance, but will have a small effect.  However, with stainless 
pipes you are talking about a substantial increase in the surface area 
in contact with coolant.  I will try to find and post a copy of the 
galvanic scale in the Files area of this site.  ***This is not to say 
that your idea is a bad one.  I just want to make sure that everybody 
knows that there is no substitute for proper maintenance, as David T 
has been preaching forever***.
