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?

Stainless and aluminum dont mix...I would use aluminum tubing.
The electrolytes in the system will start reacting really fast. If bending aluminum...no clue..there are so many types of aluminum. Get Foley on the horn...hemay know. Otherwise, find a mechanical engineer...my buddies know. I do know that the tubing you need is NOT the type sold at the hardware store...that tubing breaks. I think there is some chemical testing involved, but all the aluminum systems I have use plastic fittings...no other metals in the loop. Rich |
