Electrolosis eating heater core?
My buddy has a 94 burb and the heater cores just rot out of it. Both front and rear went out, so he bought a new one and it lasted 3 months. He took it back and they gave him a new one, but the guy told him an electrical short was eating the aluminum cores....
Anyone ever heard of such a thing? The battery has one of those battery buddy things that disconects the battery if there is any batery drain and it isn't going off, so I am doubting this story. I'm thinking his water has something in it that is caustic. Can you get Non-aluminum heater cores? any advice? Thanks in advance.

Same thing happened to me. With aluminum radiators and heater cores combined with so much electronics you get electolisis. What I ended up doing is running purified or dionized water and so far no problems. You might have him check for grounding problems to the engine.

Read this thread:
http://67-72chevytrucks.com/vboard/s...threadid=42231 BTW, I am still running on the same heater core since I changed to pink/orange antifreeze (Dex-cool). And I didn't simply drain the system and fill with Dex-cool, I had a radiator shop flush the green stuff out first. And of course I used distilled water, too.  Good luck!
