Cleaning rust from water jackets.

[tubman]

Henry, I too, am a great fan of Evaporust. My only problem was that my 5 gallons turned black and quit working well before I'd run 300 lbs of steel through it.

My question to you is : "Did you ever do the Evaporust 'thing' by running it in your engine?" I have been thinking about doing this and would appreciate any information before spending that kind of money on an unknown procedure. (Though from all my experience, it should work very well.)

No, I haven't spent the $80.00 it costs for 5 gallons to put in my engine mainly because my engine does not seem to have any rust in it. When I remove the radiator hoses from the heads and look inside there is no rust. My engine was "boiled out" when rebuilt a year ago but the water pumps that I used for my experiment were removed from the block for that "boiling" so didn't get cleaned.

remove thermostat, drain any antifreeze/water out of running engine, then put plain cheap white vinegar in the engine, run it thru several heat/cool cyles and then flush it out, I had a 41 plymouth that took two vinegar rinses to get it clean, but every on I have done this too has run considerably cooler after. Use fifty/fifty mixture and put a bottle of water wetter in there and lets go for a cruise!!
