Wait a second...when installing the thermostat...is it still loose in the block check that with a screwdriver, also, the pointed end goes UP unlike the service manual picture...which I noticed.

I ask because the ONLY available aftermarket water neck I found on ebay does not fit correctly, it uses thermostats with the rubber gasket around their perimeter else it is loose. That is if for some reason it was replaced once upon a time...

 

im new how do I make a post I need help getting a 2006 dodge stratus in time

 

So you're thinking that it could be lifting out of the inset in the block and allowing coolant to pass by? honestly hadn't thought of that however i could actually imagine that happening that you bring it up. I installed spring down that seemed to be recommended lol, but i'm curious now, is there a way i can check that to see if it is becoming unseated? as far as being able to check for aftermarket water neck all i can say is it doesn't leak when i'm done nor in two weeks has it begun to leak but i think this is a pretty stock truck.
What is the recommended gasket for this procedure i was just using paper one from az that comes with the thermostat, would gasket maker be prefered?

 

Paper gasket is fine. If the neck is really rough, I use a thin bead of RTV as well.

With the engine cold, you could disconnect the upper hose from the radiator, and start the engine..... Results could be quite surprising though.... There should be very little, if any, flow until the thermostat opens up. (don't run it that long though, that would REALLY be messy... and dangerous.)
