Re: Rusty Coolant
I used vinegar and ran it for a week, drained and backflushed thoroughly, refit the hoses and filled with distilled water and put in a cup of backing soda, ran another week and did the backflush again. That's been a year or so and I have a rusty froth at the radiator cap. I have put another cup of baking soda in the radiator and plan to run it for some time more, I haven't lost any water, but don't want the rust problem to return. Any other tips? I had put some type of rust inhibitor in the last time, generic off the shelf and I don't recall the name tho' I may have used a Red Line product as my parts house carries all their stuff.
