the 180 opens sooner.. the overall temperature of your truck is going to be based off of things such as surface area of heat exchange, volume and speed of flow, and quality of coolant.. the 180 allows the truck to start circulating the coolant before the 192 or 195, or 205 for that matter, but put that truck under load? It's not your stat that will allow it to run cooler, it's the health and configuration of your cooling system as a whole.. given, the 180 gives the engine a head start on keeping things cool..

do you guys really think 15* is going to effect whether cast iron cracks or not?

the advantage to running a cooler stat is that the engine is less likely to pre-detonate a charge of a/f in the cylinders.. it can reduce pings, based on the sliver of margin the cooler temperature allows.. the simplest concepts of 'cooler is denser, and denser equals more o2 in the a/f" is the other reason to cool things off.. add to it the PCM can advance spark somewhat safer on a cooler engine, and you get a more powerful BOOM per BOOM stroke.. = more power for same effort..

the problem with running a cooler stat without a tune is that you run rich.. you run rich because the PCM is dumping fuel in efforts to make that a/f mix it's squeezing more likely to go BOOM when it hits it with spark.. If you don't tune for a cooler stat, you're going to run rich.. running rich is not a good thing when it comes to producing power... you lose power on either extreme of 14.7:1 air to fuel..

regardless of all of this, and falling in line with the folks here who know these things- your truck isn't idling low because of a stat.. there is something else going on there.

 

And just a heads up here folks, 4085spd, and Mpi360 are the same person.

 

What's up with that? He just lost credibility with me for that.

 

Thanks for looking into that HY.

As I was watching some of the posts...he had early on lost credibility given the tantrum on the "injectors" thread. Comical to see someone post "their" proof, but then ignore further queries to expound upon it, much less become condescending and follow with show me your background b/c mine is betttter!!

Not.

Again...this is a good 180 tstat thread. Thanks for the continued vetting of the topic.

 

Thanks for the heads up, Why would someone do that?

 

The new persona always agrees with the original, which is supposed to make it look like an entirely different person is lending credibility to the first.

Now comes the fun part of watching the guy squirm, desperately trying to salvage his esteem. I might just take both of his personas off of my ignore list to make the reading easier.

 

Good question, check out rule # 9 in the "rules of dodge forum"

 

That's funny, someone has some serious low forum self esteem lol. Reading those posts he made knowing its the same person is pretty funny, reminds me of cartman on southpark with such childish tricks lol

 

Hey, be careful there bud. My other name on DF is Pegleg Cartman.

 

lmao...so hard, I nearly fell oout of my chair...and at my age, I could break a hip!
