Are you referring to the drain plug? You'll need a wrench to loosen that.

I know that this plug is one of those wrenchless ones that have no hex surface too apply a wrench to, this ones just a round plug that has grips around the oval surface so you can finger it out!

Hmmm. Never heard of such a unit from the factory. I have seen rubber replacement plugs that are used when the threads in the pan are stripped out. Those are poked in with a round tapered punch and pulled out by grabbing it with a pliers. A little twist helps it come out. Any chance you can post a photo of it?

The auto parts stores usually have a display rack full of "problem-solver" parts. I've seen replacement plugs that are over-size with self-tapping threads. That part stays in place, then it has a center bolt that becomes the new drain plug. I don't know if they come with a gasket or not. If not, I would use a little silicone gasket sealer on the threads. Tap the hole first, remove the plug, wash out any metal chips with carburetor cleaner, and if necessary, raise one end of the truck so oil stops dripping from the pan. That is so the gasket sealer will seal better. Chrysler has two silicone sealers that are very effective. The black stuff stays more rubbery and it absolutely will not seal if there is a film of oil on the parts. Their gray stuff gets harder and will bond and seal through oil residue. I used that stuff to patch a really large hole in the front of my gas tank over 15 years ago. It's still holding perfectly. The GM dealer will have similar products but the colors might be different. I only recommend the Chrysler stuff because I've used it often and know what it takes to make a successful seal.
