Sully,
Plugged in the info for both a 3.7l Dakota and a 4.7l Dakota in to Autozone and looked up a thermostat and both take the same part number. So if Autozone's website is accurate, which I would highly hope so, then they take the same stat.

 

Thanks Buddy Now I am off the get a 180 degree stat. To anyone running the jets stat did you have to mod the stat to get it to fit?

 

The jet stat is a direct fit, however $30 is overpriced.

 

very over priced. I regret paying it

 

Thank you for the reply! I guess I know what I will be doing this weekend!

 

ok, now I have the plugs and stat. Anyone give me an idea of how long this will take me to install the plugs and stat? 3.7L V6

 

plugs should take about an hour. They are pretty deep in the engine and require quite an extension! I think I had two 10" extensions on there for a few of them!

The stat is pretty easy and should take about 30-45 minutes if you do it right. I would also get yourself some new fluid instead of putting the same old stuff back in it.

Edit: just saw that you have the 3.7 (not the 4.7). I can't speak to that one. I assume it's pretty much the same thing, but two less plugs and hopefully a bit easier to get to :-)

 

wow, looked at the manual and under the hood, and spark plugs look a little more involved than just taking off the wires and pulling the plugs! Looks like once I take off the cai and thecoil bracket/ coil wires the plugs should be reachable. What were they thinking? Take me back to the dealer?

 

Its really not that involved. You will have to remove the intake though, and I also had to move the coolant lines and the brackets that hold them (they serve as the mounts for the stock intake hat). I did one plug at a time to avoid mixing anything up. Remove the wires, remove the small single bolt holding on to the coil and pull straight out. Take compressed air and blow out the hole to remove any debis. Take your 5/8" socket (I used a spark plug socket that will hold the socket to actually remove it) and loosen it up and pull out the old spark plug. Gap the new plug, put it in the socket (youll need a way to hold it in the socket if you choose to not get a sp socket) and apply the antisieze. Put the new socket in and they are rated to be torqed at 20 ft lbs. On the coil I used to silicone grease around where the boot attaches to the plug and around the gaskets to prevent mositure from getting in. Slide the coil back in, bolt it on and reattach the wires. You will need at least a 10" extention to do the job. Took me an hour and 15 minutes so not too bad.

 

OK... Here's my question guys...
What is the factory Thermostat rated at?
I'm guessing you are all from the States and trying to lower the rating of your thermostat in order to run cooler, but I'm from Canada and want the opposite. I need it to warm up faster and stay warmer in the winter.
I'm guessing a 180 isn't what I'm looking for. I can buy a 195, but maybe that is what the factory has in there already... Thoughts?
