you said you flushed with vinegar,i'm doing the same. flushed with prestone flush twice(had it in garage)now on third flush with 2 gal vinegar.each time flushed after with clean water&baking soda till I got clean water in drain bucket. still overheated.after each flush with vinegar I got a bucket full of rusty water.$2.50 a gal for vinegar,i'm going to keep it going till vinegar mix comes out clear.each cleanse it runs a little cooler.half hour at low idle in 90 degrees, I'm at 205 or there abouts.if you have the time like me a lot better than 5 hundred or better.no rad shops in my area anymore. tom
