Rust be gone!

[Fourdy]

Always had an off and on heating problem on my blown flatty. The last trip I made, the temp shot up unexpectedly higher than normal. I had to add water before heading home.

Investigating further I could see lumps of stuff covering quite a few of the cores looking thru the fill spout. I thought it must be some bars leak except I hadn't used that. I found that with a magnet, I could collect each of the lumps. It appeared to be like balls of rust.

Having read a lot about the use of distilled vinegar I thought what the heck. I drained then filled the system with 100 % vinegar and ran it around town for a couple of days.

I couldn't believe the results (as shown in the pics) of getting the rust out. The process took about an hour and a half but well worth it I believe.

Drained the vinegar then filled radiator with a box of soda and water. Ran that for a time then drained and filled with antifreeze, distilled water and a rust inhibitor.

Set the electric fan to come on at approx. 180 which it did and idled for a long time not going over a 185-190.

I am happy! Thanks to the Barn and all of you for your info.
