Oil Cooler Drain Plug Drip - UPDATE!

7925 22
I decided to install my Big Mike's Sto-N-Sho front license plate mount this morning so I removed the belly pans and came across this...
Auto part Tire Vehicle brake Brake Pipe

Gas


I wiped off the drain plug and I figured that the plug was loose so I'll just snug it up. I put a socket and 3/8" ratchet on it and I couldn't tighten it at all so now I'm left to wonder if it was over tightened or cross threaded. I'm going to leave the plastic pans off for now to see if another drip forms on the plug.
At this point it's only sitting in storage so I don't expect to figure it out anytime soon.

No. I didn't get the plate holder installed yet. I'll start another thread about that later.:)

Let us know when you figure it out. It's a fragile setup IMO. The aluminum block that the plug scres into is threaded. When you screw the plug it it just feels tight and easy to cross thread I'm sure. I'm definity replacing that plug with a valve at next oil change. Already ordered the parts.

I was there when they dropped my plastic pans to change the oil and no drips. Keep us informed.

Probably should have a dowty seal, or at least an O-ring/fiber washer.

Google or Amazon search boat inspection plates, boat deck covers etc. for example below. Many shapes sizes, clear, etc. you can get
them for thin wall applications.

Cut out belly pan and plastic aero covering wherever you want to install. Clear ones will give you visibility. And these can give you access to to perform service work without removing a ton of stuff but still seal for aero dynamics.

Done this before haven't on Hellcat yet just throwing out there having 1 or 2 placed for your personal goals might also be good to visually see fluid issues like this.

Shop around can be found cheaply.

Yikes , these fittings come to the plant pretorqued and we just install them. So they are not checked by the plant. Hopefully your tightening it fixes this issue
I'm planning to change the oil soon so I will inspect the threads and seat when I take it out. I'll probably replace the drain plug and/or the seal anyway.

I changed my oil last weekend (at 650 miles) and found why my oil cooler drain plug was dripping. There was a metal chip caught in the seal area. I took some close up photos and you can see the damage that it caused to the seal surface and the seal itself.

With the metal chip removed it has stopped dripping. I'll show the photos to my dealer and see what they suggest.

When I changed my oil a few long aluminum shavings from the tapping process came out with the plug. After the oil flowed out I cleaned up best I could with the wooden side of a large swab. I just don't like how this oil cooler drain is setup.

I would take those photos to the dealer and explain what happened. Maybe they will warranty the cooler. If they won't warrant I would do as fnkychkn suggested. Plug that hole with a something and file that entire surface flat. Then maybe sand it smooth and get a new drain plug.

I just hit 1150 miles last night. I'm thinking of doing my next oil change at 1500 (500, 1500 and then probably every 3K to 5K after that). I've got an oil drain valve (EZ Drain) ready to go with my next oil change. I think I"m definitely going to put that on so I'm not messing with the threads etc... I think it is great that they have a drain to get this low spot but I wish they engineered it a bit better. If you have any interest in putting a drain valve on there I put some details in the WIKI section. Both Fumoto and EZ Drain make them. I've used Fumoto in the past but went EZDrain this time. I thought it was better because it had nickel plating over the brass and used a viton o-ring seal vs. a fiber washer on the fumoto.

I did check my oil yesterday right before I went to a cruise night and so far mine hasn't used any.

But it will only lose a few ounces then you can recheck after the 350 miles:D:D
If I didn't have to pull the belly pan off I would have done it already. Not that it's hard but rather a PIA!

Just had my first change this AM at 600 miles. The oil cooler drain plug could not be turned out with fingers once loosened.
Had to use a ratchet on it all the way out, there were filings in the threads making it really tight.
Mechanic cleaned them up as good as he could and reinstalled the original plug.

First oil change this weekend while they warranty my front wheels. Same for Charger, belly pan has to come off in order to get to the cooler drain right? Also, only one cooler?

Same here. You have to turn it out and in with the wrench. I don't like how those threads are cut.

Yes, pretty much the same. I put some info in the WIKI section on my first oil change. Your belly pan may be a slightly different shape but everything should be the same.

There is really nothing unusual here except the extra drain plug for the oil change.

This will give you an idea of how it all looks http://www.hellcat.org/wiki/?title=How-To:DIY-Engine-oil-and-filter-change

Yep, that will do it. Glad you got it sorted out.
