CJ2A radiator been out of the Jeep since full teardown for rebuild. Prior to teardown Jeep suffered a blown head gasket. Radiator looks like it has oil/coolant gunk in it. What's the best way to clean this build up out? Really don't want to drop the money on a new replacement at 300+ dollars, other than the build up the radiator seems solid and leak free.
I was thinking maybe fill with vinegar for a few hours then flush out? I've had luck with this on nasty motorcycle fuel tanks in the past. Thanks for any pointers. |

I've had good luck with a industrial degreaser then a good rinse.
after that I use a strong mix of citric acid. I personally never used baking soda to neutralize but you could after. a good rinse again seems to be fine I have not done a radiator but many rusted parts and gas tanks. good luck leaving it in for a day, and start with boiling water. opinions might very, citric acid is not as strong as other things on the market. I will be doing my radiator soon so I also will watch for suggestions.

I have used "The Works" toilet bowl cleaner in gas tanks. It removed all the crud and rust, but it is acidic so needs to be neutralized afterwards. I have not tried it in a radiator.
There are several good products specifically for flushing a radiator, you may be better off looking into those. Edited by Oldpappy - 28 June 2022 at 11:11pm |

If you can't get there in a Jeep you don't need to be there!

You likely couldn't find a new one anyway. In my cooling issues I found that the good reproductions at most sources are on backorder.
Not that I was going to buy one (did that a year ago), but just discussing good vs. evil when it comes to sourcing reproduction parts.

Thanks everyone. Id take it to a radiator shop if those still existed around here. I'll try out some of my motorcycle tank cleaning tricks and go from there.
