    Read this before replacing your heater core! (heat not blowing hot)

    Yea for sure, I was very supprised to see that companies are just straight up selling non working cores. Sad to see, but hey now we know.

    Read this before replacing your heater core! (heat not blowing hot)

    Unfortunalty there is no way to tell if the core uses plastic or metal without cutting it open. I would call where ever you are planing on ordering from and ask. If they cant tell you, chances are its not a core you should be buying. And yes the core I got is this one, just make sure you get the...

    Read this before replacing your heater core! (heat not blowing hot)

    After the install of the faulty core there was only room temp air blowing out. After the install of the performance radiator core the heat blew hot immediatly. You can actually check if all the doors are functioning correctly without taking apart the dash. If you’re felxible enough just look...

    Read this before replacing your heater core! (heat not blowing hot)

    Hey everyone! So, I recently went through the process of replacing my heater core in my 06 TJ. Although it is a pretty straight forward job, it is time consuming and can be intimidating to the newer Jeeper. The last thing anyone would want is to have to it twice. Unfortunately, that is exactly...

    Hey all, just got the new core from performance radiator installed today and the heat blows hotter than ever. I will be posting a new thread about everything that happened and what I learned from it to make sure no one runs into the same problem as I did again. Huge shoutout to everyone who helped!

    Heat is not blowing hot (a little more complicated than you may think)

    So I cut open the stock heater core tody and can confirm the use of long, thin, metal turbulators. Next step will be to take apart the new core and see if they use plastic thicker ones like I suspect. Dont know when I will get around to it but I will update this thread when I do. Below you can...

    Looks solid, do you have any experience using a core from them? Or are they just reccomended?

    Huge shoutout to @MountaineerTom for linking that thread with someone who had a similar issue. After reading through that thread I found this one where I came across the picture below. This shows the plastic "turbulators" used in the aftermarket heater core vs the metal ones in the stock...

    Heat is not blowing hot (a little more complicated than you may think)

    The heater core is this one from Rock Auto, I just breifly read through that thread you linked and it seems very similar to my issue. Seems like a strong possibilty I got a bad core, but I wanna avoid taking that dash apart again at all costs so I will wait for a few more replies before I dive...

    Heat is not blowing hot (a little more complicated than you may think)

    If I hold it almost at the redline it will stay hot while under load. As soon as I let off or lower it to 2-3000 rpm it will go cold again. As for hot cold cycles id say its been at least 10-15 by now. I really cant see it being air after all ive done, but at the same time thats all that really...

    Heat is not blowing hot (a little more complicated than you may think)

    As the title says, the heat in my 2006 Wrangler TJ is not blowing hot. This started to happen after I replaced the heater core. I want to be as thorough as I can with this post so here is a rundown of everything leading up to this moment. My TJ had a leaky heater core, but the heat still blew...
