This thermostat has a notch on the rubber grommet that you need to line up with the notch that is pointing towards the cylinder head.

Here is a guide that will help with draining and filling the coolant to avoid air pockets:

Below you will find the info from the manual on this as well.

I do not show this engine that has a bleeder valve on the cooling line like some other Chrysler/Jeep products do, but if you have one, all you do is simply run the engine and get it warm and then open that valve until you have solid coolant coming out.

Just make sure you keep the radiator full, and I would suggest using a funnel that sits on top of the cap and keeps coolant supplied for when the air works out. I attached a picture of one option.

Please let us know what you find with this, and we can go from there. Thanks
