Fixing P0128 on My 2017 Jeep Wrangler — EASY Thermostat Replacement!

What happens here

The presenter shows a side-by-side comparison of the old and new thermostats. The new thermostat, branded Mahle, is identified as an identical original equipment manufacturer (OEM) part to Mopar, despite its different branding and significantly lower cost. It is crucial to use the correct type of coolant, which for 2013-2017 Jeep models is Organic Acid Technology (OAT) coolant. The presenter explains that mixing different types of coolants (like OAT and HOAT) can lead to the formation of a sludgy, solidified mess in the cooling system.

Goal: Verify the correct replacement part and understand the importance of using the appropriate coolant type.

What they say

link in the description below, but from what I've read is that this one and this one are the exact same one. And it's very important that you use the Mopar one. Um, it's very important you use the Mopar one because these are very temperamental. Now, if you're looking at them, you can see that these they're the same here, same here. And I know you're like, "Oh, well, he just said just use the Mopar one." And he ordered Molly. I'll show you something. So, if you look here, it says Molly, made in Mexico. If you look here, it's got the Mopar symbol. This is the old one. And the part number, look what they did here. They scratched it off. Scratched this off. So, this is the exact same as this one. Mopar. Mexico. Made in Mexico. Scratched off. Scratched off. Isn't that crazy? So instead of $60 and waiting 3 months on back order, whatever the hell it is, you can order this one for 30 on Autozone right now. Shipped to your door within 3 days. So that's cool. I mean, even your markings are all the same. 246 495. There three. I mean, everything is exactly exactly the same. I could throw this one. This is the old one. I could fill this in boiling water and get it up to temp and see if it opens. Um, I'm going to replace this, put it back on there, bolt it on, and we'll fill the system back up with coolant. So, I just want to show you guys that. I thought that was pretty cool. Um, I learned that on a form. I forget who who I heard that from, but um, I researched it for a long time. Figure out which one I wanted to order. So, yeah, it's pretty cool. 30 bucks. I'll link it in the bio or in the description below. So, hit it up.
