Acid will do it, but that's not something you'd want to do if it's already been machined.

If the rust wasn't that bad you could use a strong radiator flush after the engine is running.

If you're adventuresome, try doing it w/electrolysis: Rust Removal.

I used to send them out to be dipped at a rust removal place. But the government has forced all the alkaline dip guys out.

one more business closed

The guy I used to go to said it would cost over a million dollars to make his shop comply with the regulations, and it would take about 150 years to get his return on investment. I ran across one guy who was still doing a few on his farm and when I said no secondary containment he got real nervous, I just said it;s your drinking water supply you are messing with if it leaks.

I did see a mention about a month ago about an Australian company selling a non acidic cooling system cleaner. It mentioned working by a process called chelation.
That means using molasses.
About a 7 part water to one part molasses solution will slowly remove rust. But it need to be warm to work.

I would not use muratic acid. That is just another name for hydrochloric acid.
