Red face One more thermostat question

Before I purchase the NAPA thermostat, (530080) for my Dakota I have some questions.
1. There is talk about having to cut a small notch. Is this on the gasket or the thermostat?
2.Why is this notch necessary? Does the notch determine the correct mounting position?
3. The spring part goes toward the engine, right?
4. Where the thermostat housing is placed on the engine, does that take a gasket there?

Sorry about the **** questions but, I should be called, "ten thumbs".

My brother suggested I try to check for air bubbles before I change the stat. I can see the 2 hoses that supply the water heater. One on top of the other as they exit from the thermostat housing. Which one should I disconnect to check for air bubbles??

I bought a Prestone 330-180, 180 thermostat and it was a direct replacement. If you get one without the small bearing, you have to dremel a small hole in it. Mine went in and not a single issue.

I don't think ther's anything wrong with the factory one. It's just that as folks start adding performance stuff to their engine they want the engine to run a little cooler. I went with the NAPA one. I did have to cut the little notch in it for the gasket but, with my dremel it took all of 5 minutes. It was a breeze even for old ten thumbs here!!!

it is a good mod to do, and for under 10.00 you cant go wrong, also another good mod for under 20.00 is changing out the plugs to cooler ones, the autolite 3923 plug is a direct replacement but one step cooler. you can get these at walmart cheap

You can do the 3923s on the 3.7 ..... the info for gapping and the benifits are stickied in the commonly asked questions thread. I just installed my 3923s last night, and no complaints so far. The thermostat is next.
