I replaced the heater core and I have flushed the coolant system and still no heat, its just blowing ambient air.

Any thoughts on what else it could be. I'd really like to have this fixed before winter hits.
 
Not sure about JK's, but i know the Ram trucks you have to vacuum fill the coolant to get the air pockets out.

Since I just bought my first JK (having only owned CJ's and TJ's, still own the 06 Rubicon in my avatar) I am not up to speed on them.

Most of us raise the front of the Jeep up about 6-8" and remove the radiator cap and start the Jeep up and just let it idle. Watch for the coolant to drop and add as needed, you probably have a air pocket in it.

Hello Mr. Cooper, welcome to the JK forum. It’s not active as the TJ forum, but good people on here.

Not sure of the forums were established at the same time but for instance check out these two numbers. On the TJ forum I can’t keep up 😂

A lot of TJ guys didn't consider JKs "real jeeps". Just like the CJ guys didn't consider YJs real jeeps and I don't consider the JL or JTs real Jeeps.

It's not that they don't consider them real Jeeps. I think it's more of all the electronic add ons and do dad's that Chrysler started throwing at the JK in 2007.

I've owned plenty of CJ's and TJ's close to 20.

Never owned a YJ as Chrysler was trying to fix a problem that didn't exist and almost dropped the ball.

This is my first JK and so far so good. I thought i would like a Gladiator, but not at the prices, new and used folks want for them.

It's really just a bunch of sensors they added that give people headaches. I honestly wish they kept it the same size as the TJ though. I also prefer the 3.8 to the 4.0. 🤷‍♂️
