    2015 JKU Overheating With No Heat

    You need to raise the front of the Jeep up about 6-8", radiator cap off, engine idling, add coolant as it starts dropping.

    Let's play guess the gear ratio

    My 08 when I bought it had 35's with 3.21 gears, still has the 3.21's just stock tires now.

    Let's play guess the gear ratio

    That's what they should be for 35's, maybe even 4.56.

    Low temps and boiling sounds from 3.8

    Have you tried changing the water temps sensor that the ECM reads, i'm thinking someone else did that and fixed there issue.

    Low temps and boiling sounds from 3.8

    The sensors only read the temps don't have anything to do with controlling the temps, the T-Stat controls the temps along with the cooling fan.

    Low temps and boiling sounds from 3.8

    If you had the coolant drained out you'll need to burp the cooling system, remove the cap raise the front up about 6" and start the Jeep. Then as the coolant lowers add some more to it.

    JKU 1.9L TDI swap: Is it possible?

    I always heard those 1.9's make a good swap, you might check with Novak to see if they can help you. https://www.novak-adapt.com/catalog/engine-mounts/engine-mounts_gateway.html

    Anyone know what this noise might be?

    I can't tell anything from the video but my guess would be a U joint/joints. Does it make a clunking noise when shifting from forward to reverse?

    Anderson Cable Connector Ratings

    I bought this for the front of my truck since it would catch the most crap, it had to ship from I think Australia so order it before you need it. https://www.amazon.com/dp/B09KCGKLPM?tag=jkforum-20

    In most State's it wouldn't even be Street legal.

    O2 sensor replacement options

    Only way to tell if you have the high flow Cats is when you keep getting Downstream CELS as far as I know. Unless your buying them new then they should be letting you know about that.

    I have high flow Cats so I know all about those Foolers.

    O2 sensor replacement options

    That is called a O2 Fooler and is used in the downstream O2's when aftermarket Cats are used. The Aftermarket Cats will not let the ECM like those Cats.

    Anti-skid warning light?

    Not sure how much it can be off, but should be pretty close to centered.
