[DML] Re: kevlar wrapped header bottle

BANG!!

Galvanic corrosion does exist between Aluminum and stainless when in 
direct contact. Say, stainless bolts in aluminum. The header bottle 
is completely separated from any physical contact and todays Coolants 
are safe to use in the engines also. Years ago there was an anti-
freeze that was not safe for use in aluminum engines. I don't think 
it even exists any more, because most engines these days use aluminum 
heads. Some dealerships were not aware of it and unfortunately used 
it in the deloreans they serviced. I have heard on several occasions 
from our reputable suppliers of blocks rotting from the inside out. 
Because of the improper coolant being used. All the suppliers now 
sell stainless tanks if there was an issue they would NOT be selling 
them.  They would all be aluminum. 

Imagine this senerio

Costumer: I installed this stainless header bottle you supplied me 3 
years ago. Now I have a bad block Because of it. It's your fault for 
not doing further research. You owe me a new engine.

"I don't think so Tim!"

No reputable business person would put themselves into that position 
knowingly. I know the stainless header bottle topic has been around 
in the past.Thus far it has been unsubstantiated. However, the wrong 
coolant is bad news. Remember many of our cars were used early in 
there life and then sat for 10-20 years. If they had the wrong 
coolant in them for that amount of time, you can see where the 
problem lies.
