Radiator rust
 

I'm swapping from broken radiator to one I purchased used from someone else. Looks like a rust film thruout. Is this ok? Or should I not use it? Possible to clean out? Image attached to view and compare. If any idea, let me know.

..as of right now 86 views and nada. No one know anything? Cmon now guys

I would clean it. I'm pretty sure most radiator flushing chemicals are meant to clean out rust so I would drop it in a 5 gallon bucket mixed with hot water and rad flush and let it sit for a while maybe a day or 2(but keep an eye on it) and see if it does anything then flush it out with your garden hose...

Take it to a radiator service and have them flush it .

You way have to re paint it but that will solve the problem.

+1 & they can pressure test it while it's there.

It doesnt look bad enough to foul things up or prevent good heat exchange.
Run it and change the coolant after a thousand miles.

Thanks for posting. It makes me realize I need to flush the cooling systems on my vehicles .

Fill it up with a hot solution of 1 part white vinegar and 2 parts water. Let it site and then flush with water.

I agree w/ scottie.

I agree with all of the above :o

Clean and go.
