Thermostat delete

[stonewall]

As stated, if you totally remove a thermostat. it will run hotter than it did with one, in hot weather. it will run colder than it did with one, in cold weather. neither is a good thing. when Dodge engineering validate an engine they are looking at long term longevity. hundred's of thousands of miles. they optimize as many variables as they can. when people start changing components to suit their own whelms, or for claimed performance reasons. they may indeed see a small benefit to performance. But it will likely shorten the life of the engine long term. The reason we see engines living two and three hundred thousand miles these days. is because of the fine tuning they receive from engineering. back in the fifties and sixties you were lucky to get eighty thousand miles on an engine.It's all about miles an longevity. choose your own poison.

I ran a 180, in my 6.1, with a Spartan Max cam, ported heads, etc. Never suffered any issues, with wear... and yes, I did my own work. Had the engine apart a couple of times, for upgrades and it always looked pretty tasty.

Not saying there my not be issues, for some... but these engines are more robust than others.

If you didn't measure anything in the cylinder and rings, then you really don't know. But many other have tested and measured... wear does occur.

I never claimed zero wear. What I said is that, the engine never suffered any issues, because of it. 600 rwhp 6.1 daily driver.

Doesn't matter, anyway. Engine had 190k, on it and ran like a beast. If it had trouble, I have the skills to fix it. Because of that, I don't mind pushing the envelope.

Everything wears, my friend. Everything

So, you are that guy that hurts his cars with mods and then sells it to a trusting, unsuspecting new owner who finds out the previous owner hurt the car and didn't say anything. There are many threads on various boards discussing this very issue. Glad to know for all to see that you are that guy who does not respect these cars and does not care about the next guy.

When a lower thermostat is installed in a car, it hurts the motor... full stop. Any other belief is just rationalization. No amount of arguing or denial can change physics or science and established data, but maybe if you keep saying it, you just might come true and you might start to feel better about a really bad choice.

Like many on this thread, we know it is a really bad idea to change thermostats to something lower so hopefully we helped those willing to listen to facts.

UNFOLLOWED!

So these engines are designed to run at certain operating temps. But the reason they run as hot as they do is for emission reasons. You aren't going to find you simply ruined your engine because you put a 180 thermostat in. Would I drop to a 140 or 160 no I would not that is just to cold. But backing off the temp of the factory temp a little isn't going to ruin your engine.

Seems this thread is getting a little out of hand.

The one thing I think everyone agrees on is to keep a thermostat in your engine LOL

Saying someone doesn't respect these cars or what happens to them after you own it(does anyone though???) is a little out of line IMO, especially to someone like @Diboblo

When running a 185 your temps still exceed 200*… it just opens sooner. Dodge recommends one on modified Hellcats - and they only warranty the mods if it’s there.

 

[ChargerChallenger]

Just put an air cooled engine in like the VW bug set up and nothing to argue about😁

 

[DGatzby]

Oh, and how I hesitated for about two seconds last night as my thermostat housing was open. To install or to not install was the question. Yes, it got the transplanted 180 degree unit before more of the slick sweet smelling stuff rolled out into the bag. Thanks again Eric, you and I have been doing that sort of thing for over 15 years now. Never seen a more happy engine than one that runs below 200 on the street, better around 185-190

I have never seen 200 with mine. My 180 runs at 185 and when it gets to 195 it opens and goes back down

Yes, but do you have your fan settings specifically set for this t-stat with a custom tune? I was talking about running a 185 with the stock tune and fan settings.

Yes it is. Most will throw a CEL if you don't, mine did so my thought if someone is running a 180 then they are tuned for it

Mine has a 180° stat. The car loves me and I love it back.
Marriage may be on the horizon.

😍😍😍😍😍

If you had a 185 and not a 180 your temp would be 200 not 195. See how I just added 5* and solved for x? lol
Really though, it’s more symbolic than anything to help the anecdotal evidence on the site align with his charts… anything above 190 on his chart had negligible wear… and that’s where we are regardless of whether or not the tstat is 180 or 195… we are above 190.

I agree with the tune… retune when you restat.

a lot of people call the 180 a 185 because that is where it runs. Didn't know people where running a 185

Just a couple thoughts, I do run a 180-185 or whatever without a tune, it does keep the car cooler at almost all times, but will still spike to 220 water temps in traffic idling and such and can take a bit to drop back down to around 200 until you are moving and get some air flow.

Also all 180s do not behave the same. This spring I ran a Mishimoto, and that one did open in the upper 170s and then settled to around 179-180. The Jet 10183 which is believe is also the same as the Motorad 4128 will not open until 185-188, then will hope about 185 until you are in traffic and such. The Mishimoto gave me a code right away. I do not get a code with the Jet/Motorad on the stock tune. That abut extra 10 degrees before initial open seems to make enough of a difference.

One last thought, I usually swap the stock 203 back in for the winter season, and my car runs at almost the same coolant temps in the winter with the 203 as it does in the summer with the 185

Your fans need to be reset.

So, you're the guy who gets his exercise jumping to conclusions? You don't know me, troll. LOL

Hey... drive your "original" car, in your sterile bubble. It's cool.

In the men time, I'll do whatever the hell I want, with my car... and enjoy it... because I can... with a 100% clean conscience.

BTW... dude flew down, from Montana, to buy my (hurt, modded car (your words)), solely because of the work I did. He then drove it back, zero issues.

Let's get back, to the OP's question... not cool, to delete the thermostat. Period.

This place cracks me up...

You’re correct, they’re advertised as 180s…
I wasn’t here to be taken seriously… it’s a thread about removing the thermostat.

Like most threads here, they eventually morph into another related subject. BUT, it also adds to why I like this forum so much. Great discussion and disagreement. but that is how we learn by maybe considering someone else's logic. twisted as their logic may be , it just needs to consider more than that one supporting fact to be logical
