Question for the cooling gurus. I am using an aluminum block motor and an aluminum radiator. I will have some rubber hose connections but also would like to have some formed metal lines in the system. Do I need to figure out how to bend aluminum tubing or can I go with steel or stainless steel with out fear of electrolysis as long as I run the proper antifreeze? If I have to bend aluminum tube does anyone have hints for what type is best suited for this?

As far as the electrolysis is concerned this is not uncommon knowledge at radiator shops and even the auto parts stores. Any different metals in the system will react, alum and stainless being a really poor combination. You can monitor the PH to get a clue and even put in a sacrificial anode like they do in marine applications.
My car runs one inch hose front to back and I found some old lawn chairs that were made out of 1" tubing worked great. |
