Coolant leak

So I noticed a small stain on the driveway and slid under the Jeep to check it out. It looks to be coolant as it has a sweet smell and is kind of sticky. It is dripping just a tiny bit from right around the oil drain plug. It looks like it is leaking down and just dripping there and onto the ground through the hole in the skid plate. Ideas? I am out of town for a few days so will have to check it out more thoroughly after I get back.

If its by your oil pan drain it could be your block drain plug leaking that it right above the oil pan about 2 inches and can be seen through the hole in the skid plate

It looks like it was the thermostat, at least I hope this was the issue.

Was the o-ring broken when you pulled it out? A little hint now that it's out.....I've had problems with "other than stock" thermostat seals/gaskets. As far as I've ever found, the stealer is the only one that has that o-ring, and it only comes with the thermostat (~$30). You apparently can't purchase it separately. So, I've tried numerous different gaskets, and all eventually seep or leak, except for the Fel-Pro P/N 35840. I've also tried gaskets with and without RTV, as well as RTV on an old stock o-ring. Some lasted a while, but eventually started seeping. I ended up going back to the stock setup, but a different thermostat housing (other than the stamped metal) might also resolve the problem, using a gasket. Let us know what you end up doing. I think the seepage happens with a gasket because of the aluminum timing cover and the metal thermostat housing.

That orange o-ring was like that, I didn't break it. Sorry I forgot to mention, I replaced it with a Mopar thermostat, $36 at the stealer. This was a newer revision that superseded all previous versions and it had a black o-ring. I don't know what the previous revisions looked like but the guys at the dealer were talking about it. . No puddles under the jeep at work so we shall see.

That must be somethng fairly new, as I've not seen the black o-ring...just the orange ones. When you installed the thermostat, did you install it with the "wiggle"valve (bleed) at the top? Did you pull the allen plug, on the housing by the thermostat, before you filled the system? If not, you'll have lots of air in the system, and it'll take forever to get it out. Also, you'll have a good chance of overheating. What kind of coolant did you use. Should be the HOAT stuff, mixed 50-50 with distilled water.

I did install the bleed valve up like the old one. I used distilled water and Mopar HOAT coolant in 50/50. I didn't pull the allen plug but I did run it with the radiator top open for a bit slowly adding coolant, and the heat on. I did get a good amount of burping at the radiator and coolant reservoir. Was 93 today and I drove quite a bit in stop and go traffic and the needle never went above the second mark below the half way point on the gauge.

Here is the baggie the thermostat came in for part # reference



Here is a picture of it actually.

I think you'll be Ok. Just keep an eye on it every morning for a week or so. I had to add a little at least 4-5 times, before it stayed where it should. That black o-ring looks a lot more substantial than the orange one. Bet they had too many problems with it, and that's why they changed it.
