Re: Electrolysis in aluminum radiator - Help
Ill have to pickup some strips to check ph.
Yellow optima is out of truck. Using 10ga wire with eyelet on one end and heavy test clamp on other to ground each head to steering box bolt ends....still have .5v My buddy brought over his fluke last nite and we tested turning on/off fan, fuel pump and water pump with no change. No voltage leak at battery to the bed where it is mounted... Please keep advice coming. Thank you |

Re: Electrolysis in aluminum radiator - Help
Are you thinking it is the electrolysis that is causing the hoses to bulge? Not saying it isn’t possible , but I’ve never heard of that occuring. Is there a voltage reading with the anode removed?

David Reher talked about grounding alum heads to block. We saw issues early on in police car builds. Electrolysis killed heater cores and radiators yearly. We tried everything you spoke of. Ended up replacing rad caps every three months.

Re: Electrolysis in aluminum radiator - Help
Here is 1 article penned by David Reher...
http://garage.grumpysperformance.com...n-cooling.149/ I will have to have my old man come back over and re-check the grounds. He put heavy star washers under all of them, but I wonder if my paint job on the frame isnt scuffed enough under those grounds. |

Forgot to say; Test the alternator for a leaking diode if you have not done so. Seen lots of those and yes it reduced cooland voltage.

Have you ever media-blasted an aluminum component after an electrolysis problem- it's horrifying. It can look like the part in your hand is all aluminum and intact before you start, but when you start blasting, the cancer is cleaned away, and you're left holding something that looks more like a piece of Swiss cheese. |

Re: Electrolysis in aluminum radiator - Help
Mark you said you've raced the S-10 all season and within the last two weeks this problem has come up. In the last 3-4 weeks have you changed anything on the car?
