No, I just fill it up, start and run til it reaches operating temp, let it cool, then top off the coolant through the radiator cap. May have to add a little to the reservoir after the next couple of drives.

I thought the factory procedure is to pull vacuum into cooling system, to evacuate any air. Then suck in new coolant through a valve. This way there is nothing to burp, as there was no air in the system to begin with.

The 06 fsm doesn't say anything about pulling vacuum.

I would think you could also just disconnect the heater hose from the thermostat housing and fill until it reaches that nipple before reconnecting the hose and finish filling.

Why not to just to buy the Mopar one? The Israeli factory that makes it, is supplying the the car manufacturers all over the world, not just as a replacement, but as something that comes from the factory.
It also has the jiggle, so you don’t need to drill anything whatsoever.

Is your mopar stat stamped motorad? Mine from Amazon is but it just came in a white box and is different than the standard motorad I ordered.

It does not say anywhere Motorad. However, there is a single factory in Israel that is large manufacturer of thermostats, and it is Motorad. So I am 99% sure that what Mopar sells is Motorad.
They supply today significant percentage of cars in US, Germany and China, and I am not aware of any quality issues with their product.

Thanks. I'm not concerned with it being motorad or not. My mopar unit didn't come in a mopar bag. It had motorad stamped on the Stat though.

The thermostat I put in a few years ago when I reworked my entire cooling system was a MOPAR. Came in a bag, not sure if it had MOTORAD stamped on it or not. Everything has been working fine.

So to summarize:
Mopar is motorad. It comes with the jiggle, so you don’t need to drill anything. Just install and be done with it.

You might check out the part number I listed next time around.

i don’t think that part number you supplied is OEM. Those were the old Stant high flow, high performance mags sell them as their own brand, has a bigger valve. But if all the OEM thermostats I removed, they all looked like a Stant Superstat with a jiggler valve.

It's not, I've tried them back to back with the OEM style and it was easy to tell the difference. I don't think anybody needs to run them but for what they cost it's what I run. It's a thermostat, not a big deal if it's the right temperature. I just don't understand why people spend more on the wrong deal without the valve.
