Rust in coolant

Hey guys, so I was driving my 93 YJ home this morning after letting it warm up, had no problems, then when I got home, i noticed steam coming from the engine compartment. When I opened up my hood there was rust colored fluid everywhere. One of the return hoses had a hole in it which i fixed, but as I opened up my radiator to refill it, I noticed there was alot of oxidation inside. Was wondering if anyone else has had this issue, or if its common and I just need to do a flush? Thanks in advance

You can try flushing it, it will only help. Last radiator I saw like this took mtiple flushes and it was slightly better. It ended up failing a year later.

Funny you should ask,,
during my engine swap I used the chevy radiator that had rust and tranny fluid mixing with the coolant. It made a rusty/oily mess in the engine
I installed a new aluminum radiator and poured Calgon liquid dish washing detergent in the radiator and let it run hot.
I did this atleast 10 times.
Let it run hot and pulled the bottom hose for a quick release of water in the radiator.
Now im running clean and havent had anymore problems
