Aluminum Corroding

[kevin01cobra]

For some reason unknown to me, the alternator, throttle body, lover intake, belt tensioner, and the block are all corroding. I do not know the cause but I am sure it is not the battery because I have been unable to find any leaks or battery fluid. How do I clean off the corrosion and what else could possibly be the source? I only clean the engine bay with water and a rag.

If it somehow is caused by battery acid, a can of coke is a good inexpensive place to start. Crack open a can and pour over everything that is corroding. Let it sit for a few minutes and then go over it with some soap and water. Anything other then coke won't work. If that doesn't work, throw up some pics and i'll see what else I can come up with.

well I was gonna suggest something until I saw that you are from Texas and I figured that they probably dont have to salt and de-ice the roads that often. LOL!

i think most raw aluminum will oxidize/turn white ish like you are describing. i dont know if there is anything you can do to fix it. anyone?

you must clear coat it when in raw form before it corrods, otherwise you myst abrasively remove the oxidation back down to raw metal. FYI glass beads work well, in a blasting box to remove it from block and alternator and what not.
