One of the more persistent issues that I have been having with my El Camino has been that the antifreeze will turn rust brown over time and flushes do not seem to permenantly solve the problem. I had changed the radiator out to a new one and replaced the antifreeze with new, and that seemed to work for a few months but it ended up turning brown again. When I pulled the engine, the coolant was too far gone to reuse.
Is there any way to stabilize the block so it will not be constantly rusting up my coolant?
