My turn, new radiator!

Hey guys, I read the Forum almost daily, but haven't needed to post in a while. My Jeep is a 2015 Sahara, I ordered it brand new and it has 21,000 miles, fully loaded. I was underneath it doing some minor maintenance to it, and looked up at the bottom of the radiator on the driver side and can see some dry antifreeze. I wasn't surprised by keeping in touch with the Forum and noticed a little coolant was low in the bottle too. Does anyone know if this is part of the five-year hundred thousand mile powertrain warranty? If not what is a good radiator to replace it with? I don't want to put a stock one in there and three years later have the same problem again. Thanks

No idea if it's covered, but here's a coincidence for you. We have 2 2015s, both of which now have a coolant leak in the radiator. Both looked clean a month ago. Getting both replaced.

EDIT: Now that I think of it, I think it's only covered on the 3 year, 36k mile warranty. The dealer mentioned to me that our extended warranty saved us the cost on this.

Yep, covered under the 3yr / 36k warranty and not the powertrain. Mine let go a little while back (also a 2015). I was within the 3 yrs but over the 36k and fortunately the dealer covered it. If they had not, it was going to run a bit over $800 at this particular dealership. The mechanic we take my wife's Odyssey to quoted me around $550 using the OEM radiator.

From my readings and forum searches, most of the aftermarket ones aren't much better... Maybe someone else can recommend which one they have had success with.

That's a lot of money to have a radiator put in. I've replaced plenty of radiators in the last 45yrs of doing my own work. Looks like I'll be doing another one. I'm going to look for something that's all aluminum. I am going to stay away from the plastic tanks.

Ah its not covered under the 5yr power-train? My 2016 just passed over 37,500 miles and I noticed my coolant was low. I filled up the reservoir above the min line and will be keeping an eye on it. Haven't found seen a leak yet so hoping it was just low.

I like the griffin radiators in general if they make an exact fit for your year and transmission would definately check out their exact replacements, or go a step up to their combo unit. I run 2 big griffins on my rock buggy and it can run all day in the open desert.

That was not a fun job. I did mine on my 07'...not sure if the newer ones are the same or not. Like you I've swapped many a radiator over the years but the way they decided to mount mine was just stupid. There is a think plastic mounting assembly that wraps around the side of the radiator. Was such a pain in the ass to get those side bolts in and out. My girl wrenches luckily and she was able to get them back in because of her small hands. I was having a bitch of a time. Hope yours goes smoother lol...good luck!

I did my 07 back in the winter, took me 4 hours start to finish and I took a break here and there. My first time on a JKU and wasn't too bad.

There are two good youtube vids on this, that's how I did mine, the two bolts were for the transmission cooler I think.

Griffin is local to us and our go to for radiators. Heck, I was there twice last week. Great group of guys with a great radiator. We never had a issue with them! We run them in our Ultra 4 as well.

Same here. 2015 JKU Sportn had the radiator replaced at 27000 miles. Also had the thermostat housing, timing guard, head gasket and cylinder 6 done as well. Had coolant leaking into the block...cracked cylinder head and everything. Was all covered under the 3 year 36k.

^^^This. I put this in my 2009 JKU after I blew a really bad leak in my radiator. I installed this in about 2 hours, a lot easier than I thought, don't want to do it again but I'm fairly competent with vehicles though. They provide exact instructions.



******YOU DO NOT NEED SELF TAPPING BOLTS ALL THE FACTORY BOLTS ARE ALREADY SELF TAPPING. It is aluminum and has pre-drilled holes. You do however, have to grind a bit off the factory fan shroud to make it work (took 5 seconds) I put that in caps because people keep claiming you need self-tapping bolts. Something else people say is that there are clearance issues. It is a TIGHT fit, you are installing a 3-row but it fits and slides right in.


Very happy after installing this. After driving home from work you physically couldn't touch the hood of the jeep because it was too hot. Now I can open the hood with no issues and it is running cooler.

Add me to the new radiator list. I bought a 2015 JK Rubicon 2 door with 14,000 miles on it a month ago, and have put about 300 miles on it installing lift kid, winch/bumper, tires, jack mount, skid plates, Bedtred, etc., and shortly after I bought it I noticed the smell of coolant after I stopped with a warm engine. All similar to a lot of symptons others have described - smell coming from driver's side of the radiator, near the headlight area. Could barely tell any change in the coolant in the recovery bottle from a leak. Took to dealer, pressure checked, found leak in radiator. I could never find a leak anywhere, only the smell, and took the check to find it. I'm going to be out about $800 for the replacement with the factory radiator unless I can talk the dealer into covering this under powertrain warranty since it's 3 months past 3 years on the 3 year/36K factory warranty. Dealer had a lifetime powertrain warranty that came with the Jeep but doesn't cover the radiator.

Does anybody know the status of the potential class action lawsuit on this mentioned in other threads?

Thank you for the heads up!!!

Im also in the market for a Radiator. i have a 15 JKU with 33000 miles. I went to the dealer the other day to discuss the possibility of doing it under warranty, but i just kept getting the run around. All they would tell me is they have to troubleshoot and submit the warranty claim. I would be responsible for a $150 diagnostic fee. I said hell with them and plan to replace it myself. I have been eyeing the aluminum one on Amazon i think its what ill eventually go with.

Make sure to educate yourself on the proper coolant to put in it. (OAT or nothing)



Also, thermostat housings fail at a rate x2 radiators...might a want to replace yours while you have it ripped apart. Re0use the OEM gasket, or you'll never get it to stop leaking.


Fun job, I did my 2014 Sahara not long ago.
