Anybody with a 180 degree t-stat please read

Yeah, older ones use HOAT.....

Was thinking maybe it's a different color but I don't think it should be brown.

2013 and up use OAT which as of a few months ago only mopar sells the correct coolant. I found this out the hard way when I topped of with hoat after switching to a 180 tstat and had to do a complete flush.

Hopefully it's not a major issue and they don't try to say the tstat caused it. Goodluck!

I just used the same color coolant from autozone on mine. Zero issues.

Yet. Be careful.


Chrysler switches to OAT antifreeze for longer service interval - SAE International

It's my understanding that just because it's the same color, it may not be the same chemical composition and mixing coolants can eventually cause issues.

Chances are nothing will happen but the last thing I wanted was to have an issue down the road and have Chrysler say I voided my warranty by using the incorrect coolant.

Here's what I use:

Prestone/5/100 antifreeze and coolant AF888 at AutoZone.com

It's OAT. So either I lucked out or the colors do somehow correspond to the type of fluid, which I believe is correct since there are a lot of owners and maintenance manuals that say specifically NOT to mix colors.

Read the article I posted above. Not all "OAT" designated coolants are the same chemically.

I know that I took my 2004 Rumble Bee in to a little oil change place when I was working out of town in Texas. They did the oil change and "topped off" all of the fluids. A month later, the lower section of my radiator "plugged off" and I had to replace the radiator. Tried to flush and a few chunks came out, but it wouldnt unplug. Looked like rust colored Spam jello. I am a firm believer in triple-checking coolant type before adding lol. Let us know what they say. A 2014 should not need anything yet and should damned sure be clean still!

^ That's why I spent $40 on a gallon of dealer agreed proper coolant for my particular truck per the VIN. Even though I just needed a couple cups to top it off it's hella cheaper than problems in the long run.

A lot of my mechanic friends are saying it's oil from the picture. But they have yet to look at it yet. This impala rental though. ...

Yeah, I could only find HOAT at O'reilly's local. I was not going to go to the dealership..lol

Ouch,,,, I just don't see on a brand new truck

I know I'm resurrecting this thread, but that looked like an oil cooler failure if there is on one 5.7... What ended up happening with that?

Mine ran 185 winter and 190 summer. Never ran 180.

This is what it stays at, sometimes a few degrees higher. My tuner reads the same temp as well.


If guns kill people, then pencils misspell words, cars make people drive drunk, and spoons make you fat...

Tuner reads from ecu anyways..

I have mixed thoughts on the 180* thermostat. I have been told it can actually harm your engine but also read alot of the trucks on here swapped to 180*. What is the real benefit of putting on a 180* therm?

 

[NCRaineman]

I'm not sure there is any benefit to running the 180 T-stat on these newer trucks.

Years ago heat was your enemy on the older iron block / iron head engines, but all this new stuff is built to run between 190 and 210. If anything running 180 without a tune is going to have the ECU thinking the engine is constantly cold, so it will be adding fuel trying to warm up. When I first take off in my truck the temp will get up to ~213, then the t-stat opens and the fan kicks on, dropping it down to around 200. After that it stays between 195 and 205.

It's the rubber gaskets (valve cover gaskets, oil pan gaskets, etc.) and valve seals that I worry about with higher engine temperatures. The oil gets hotter and rubber parts can become dry earlier than they normally do causing leaks.

The trucks go into closed loop mode at 160F,so a180 T-stat won't affect anything as far as the computer thinking the truck is still cold

I've had mine for about 5 years never had any problems. And I've ran them in other cars for almost 20 years. They won't harm your engine.

Mine stays at 185 to 188 on the hwy. It might creep to 190-195 in traffic but it has never reached 200.

I would realy like to believe that. What worries me is our new trucks are so electronic. Computer and sensors all over. If I change out the factory therma for a 180* will it set up a interface issue. I did change to 180* therma in my 03 5.7. No issue other than it runs about 5* cooler. But that 5.7 is not the new 6.4.
