No white smoke out of the exhaust . Oil is not milky . I know as of late when I park there is a small puddle of coolant ( looks rusty) under the Jeep. It’s parked until the 28th so my local guy can look at it. I am getting a whooshing sound at the heater core on startup some times. I’m hoping it’s not a blown head gasket.

There's a test kit you can buy to check for combustion gases in the coolant, you could do that to save yourself some money.

You would be amazed at what one small bottle of K-seal will do. I had a water pump leak and a lower intake manifold leak. Added one bottle to overflow over 2 years ago and still bone dry. Zero issues whatsoever.

Used it once for the water pump sealed it in 5 minutes. Used it a year later for lower intake and sealed in 5 minutes. That was years ago and coolant has not been changed. K- seal is the only thing I would ever use. Add it and take er on a half hour run. Then have🍺

Took some quick readings after my drive . These are while the old girl is in idle.

Unfortunately time is a factor. I have none. I work 12 hr shifts and we are in overdrive atm. I’ll have to bite the bullet and pay someone to do the work.

Not related to this post, but having a similar problem.
Literally 2013 jku is dripping on driverside bottom corner of radiator! Possibly replace, but was wondering if the K seal or like would work in this situation.
Apologies for inserting my woes in someone elses post.
Thank you
