2003 Rubicon Plastic Radiator Drain plug

I have a 2003 Rubicon TJ. Pulled the drain plug to drain the Radiator and when I put the plug back in it doesn't tighten up and drains the rad one way I turn it but when I clock it the flow stops but it does have a small drip.

Any thoughts and ideas??? I don't want to change radiators - this one is clean and works just fine - except for the new drip!

The radiator petcock doesn't normally need to be removed, just opened to the point that it allows the coolant to drain out. You should be able to replace the seal on the petcock if it's leaking, or you can replace the whole petcock (Mopar 4773259/Dorman 490-234.1).

For this reason, I never open petcock or drain plug from radiator to drain coolant. Years of heat cycle does a lot to things.

I always undo lower hose to drain the coolant.

My petcock got stuck and the wings broke off. Fortunately it was stuck in the closed position and I was able to do exactly this.

Petcock & Lower Rad Hose.

Yea new to me I was surprised it came out. As I understand it now it is basically closed when the handle is horizontal and open when it is vertical. Mine turns all the way around and I finally figured out I didn't have it @ a full 90 and it was seeping out the edge of the petcock. Seems to stop completely when it full 90 degree horizontal. I ordered a new petcock. Any idea on installing it - putting some lube on the O ring to make it slide in easier??

I also see that just unhooking the lower hose drains it much faster and easier. Leave the petcock alone!!!

Thanks

I'd just use a smear of petrolatum on the new seal before install.
