Aluminum Top = Corrosion?

johan851 · Nov 5, 2003

This should be a pretty quick question. I have a Dtek Spir@l with an aluminum top...does the aluminum on the top of the block cause ionization/corrossion problems with the rest of the copper system?

The top should be anodize which prevents this but an anti-corrosion additive like antifreeze should be used anyway.

I belive that D-Tek andonized your block well.
also, I would use zerex or similar.

I'm running the same block you are and I've opened my block twice to check for corrosion. I haven't seen any. The block top looks like it is new.

BTW, I've been running my block over a year.

Even with anodized top its alwasy safe to use 25% anti-freeze in your coolant solution

Yeah, I was planning on using corrosion inhibitors anyway - some red/orange antifreeze and some other stuff I found. Glad to hear than anodizing prevents that kind of corrosion.

Thanks guys.

When buying anti-freeze for corrosion protection, dont go for the cheapest stuff, get good brand anti-freeze as the better/more expensive antifreeze has better corrosion inhibition and covers a wider range of materials.

Alright, will keep that in mind.
