    I would agree with Rambler and replace it. Lots of good aftermarket radiators. Good luck -

    If the radiator can take it Muratic Acid can be found at grocery stores by the large bottle. Best way to do it though is lay the empty radiator down flat on the ground away from everything like on the cement in the back yard or similar. Leave an old cap on it. Close off the bottom. Fill from the only remaining hole. Leave it lay there for couple hours. It will get warm. Then empty into safe bucket or container. The acid is household and not too strong but yet strong enough to clean out some gunk. Replace the cap with a new one and be sure to flush with plenty of water. Shaky, Shaky! I used this method on my 55 Williy's truck radiator back in the day. Don't inhale :anonymous:.

    Eventually I got a new one as I also changed to a V-8.

    Good luck!!
