    Trying to do my fluids, I drain radiator via the plug, after the drains complete I put plug back in it’s spot no big deal.. until my new fluid is leaking right out as if the plugs not in there. Easy enough fix. Except the replacement plug I purchased is not the right one, and nowhere can I find a photo of what a oem drain plug should look like, at the point I’m thinking maybe I have an aftermarket radiator. Any help is appreciated can add pictures but the old drain plug doesn’t seem damaged.

    There should be an o-ring on that plug.....just got to find right size and thickness...
    liberally put silicone lube(spark plug boot grease) on the o-ring and put back on plug.....
    most likely yours has a break/tear...or gone...


    Or do what I do silicone(rtv) the plug permanently shut and drain by dropping lower hose....

    It does happen, there aren't replacements unfortunately, it may be aftermarket.

    You could try to teflon tape the threads, or drain it dry and use JB weld to ensure it never leaks.

    I am in the process of replacing the radiator in one of my 1995.5 trucks. Here is a pic of the OEM drain plug. Is it possible that the oring was missing off of the plug in yours?

    Can always tap and thread a brass plug fitting on...but you need the right tap.

    It was the o ring, when I removed the screw the o ring got pushed into the bucket without my knowledge, and it’s definitely an aftermarket radiator. Thank yall
