THERMOSTAT REPLACEMENT - DODGE RAM 1500 HEMI 5.7L

[@BoostedMotorsports]

*HERE IS THE STUFF TO GET THE JOB DONE* 💪😎 HERE IS THE 180* THERMOSTAT WE USED amzn.to/2K0xtsE MOPAR 5 Year Coolant amzn.to/2Wtimio MOPAR 10 Year Coolant amzn.to/2EsNrIO

[@jonathanwallar5978]

2011 Ram 5.7 HEMI I did a coolant flush and replaced my stock thermostat with the 180⁰ one vs. the stock one. Before I started, I didn't have any heat and my temp gauge sat just a little under halfway. After I finished the job, I now have good heat, but my temp gauge only sits at ¼ of the way. I was just wondering if anyone has come across this before and what might be the remedy to fix this? I would appreciate any insight. I love watching the Boosted Motorsports videos! Thanks!

[@mcneel16]

So if I switch for an E fan would my truck run perfectly fine as is or is there some risk to not changing the thermostat or adding a tune?? I'm asking because I'm interested in installing an E fan in my 2010 hemi but when watching all your videos on installation and then possibly needing a tune + TSAT change I'm kinda becoming skiddish. I mean I use my truck as a day to day driver, vacation vehicle, and every once in a while heavy loads. So I would like all the information to make this decision or if it's not even worth doing. Thanx Boosted you helped me repair broken exhaust manifold bolts last year 💪

Thank you, your video is the first one that details a less messy way to drain coolant. I changed a thermostat on my Camaro in 1999 and this is the first thermostat I've changed since then. My neighborhood has loose dogs and cats and you helped me not have to learn the hard way. 😊

Your instructions were simple and precise. Thanks 🙏🏽 I completed the task this evening

[@bjfishy123]

Had temp going up to 240. Replaced everything out but it turned out to be a clogged radiator. Change it out, the coolant passages on these trucks are very thin. A radiator shop can do a flow test to confirm this.

[@BoostedMotorsports]

Its most likely because your truck has the active grill shutters. They stay closed so that your truck runs hotter. If you want the engine to run cooler then you'll need to get a tune to reprogram the fan to come on sooner and delete the active grille shutters. Check out the other vid I have on this where I document this exact problem 👍

[@davidwilson1352]

Hey man I was curious if you can help me out. I owned my 2009 dodge ram about 6 months and in that time I have had to change out mine twice, both added a 203°. After each change truck would run fine but then would throw a code saying bad thermostat, obviously it may be something more than just the thermostat, what would you think it could be?

[@Weak_juan]

Any reason why fca would go with a 203f instead of something lower?

To meet California emissions standards nationwide. A hotter exhaust makes the cats work better and lowers emissions. Most manufacturers try to make all their vehicles meet California's strict emissions standards, even if the vehicle is sold in Oklahoma or Maine or South Carolina. In the 1970's manufacturers made separate vehicles for California, but that was more expensive. It's cheaper for them to just make all vehicles the same, and that means all must meet California's stricter standards. I did this mod on my '15 Ram a year ago. It's easy to do, but I wish I would have watched this video first to get the tip on the coolant draining. The Boosted2K way is cleaner and easier than the bonehead way I did it. My Ram runs about 190 on the freeway in summer now with a 180 degree thermostat, which is much better for the engine. And yeah, I live in California, so sue me.

[@BoostedMotorsports]

Thor Swenson exactly! Do your temps swing at all on the highway? The programming on my truck keeps closing the damn active grill shutters on the highway and bringing my temps back up

[@PRO4XKEV]

so you did not do any performance tune with the 180 stat? just a remove and replace and never see a code come up huh?

[@BoostedMotorsports]

I have a DIablosport tune on my truck right now. I've heard it can throw a code on a stock tuned truck though in cold weather!

[@zr1vetteman09]

it is a good idea to get the oil to at least 200 to help remove moisture and fuel blow by which then would be sent through pcv back into engine or catch can ideally, not to mention operating temp oil is usually around 200 where it reaches its full viscosity/protection rating. That said, this shouldn't drop oil temps much if any.

[@j.d.mcginn6946]

A 180 stat us fine but especially in the south a 160 is even better. I have a jeep grand cherokee- with 5.7 so I will need a high perf radiator which I will be getting. Both the engine and the transmission- heat kills them both. If you can run 165 to 170 water temp your engine trans all rubber parts literally the whole truck last far longer.

[@dennisolson6051]

This only works if you have a programmer to set new operating temp. If you don’t all it will do is trigger the computer to up the fuel to air ratio until you get to operating temp using a shit load more fuel.

[@r.b.l.5841]

But for those who live further north it may be best to use the 203 so you don't freeze your butt all winter.

[@Electrified_14]

Powertrain Engineer here. @kevin maxey said in a comment below "The engine will run more efficient with the factory tstat. Cooler is not always best." He is absolutely correct. There is virtually no cost difference in a 180 to a 205 thermostat from an OEM standpoint. The engine was engineered to run at those temps for a reason. 200-215 F may be the efficient range for multiple parts inside the engine. Lowering the temperature may effect this and in turn reduce the life of your engine. I will admit there are multiple examples when the OEM doesn't get something right and after market engineering is the way to go. This is not one of those time.

[@BoostedMotorsports]

From an emissions standpoint you are correct. From a performance standpoint cooler operating temps = less detonation and more ignition timing you can run.

[@wirenut003]

I was told that the injectors will run better with the OEM stat. Any truth in that

[@andyflorida6269]

some answers are wrong 180 degree only means the will open when the temperature hits 180 after it opens it will run at normal operating temps. also 180 degrees means you will get heat coming from your hvac quicker because it opens at 180 instead of 205

[@pierreverdoni]

@@andyflorida6269 I would say the opposite.............If the thermostat does not open until 205 to get cooled then the heater core is getting more heat ,and sooner

Does the fan need to get reprogrammed? Since it really only kicks on close to 200°

[@BoostedMotorsports]

Fan comes on at about 220* with the stock computer unless AC is on. Its a good idea to get a tuner if you are deleting the mechanical fan but it won't overheat or anything if you just swap thermostats.

[@shostang]

Read what the guy below says as he's correct. Your PCM is looking for 203 and will do everything it can to get it to that temperature. You're going to run rich and in a 2013 with its copper tip plugs, they're going to foul out much sooner.

If you still have the stock mechanical fan setup I would say wither your electronic shutters are stuck closed or your mechanical fan clutch is shot. The electric A/C fan comes on around 221 degrees but should rarely kick on in normal situations besides turning on the A/C

Theres alot of people confused about this, including this guy in the video. To all to whom drives mopar hemi engines,when putting a 180 stat it keeps the engine cooler longer than a stock 203 stat. Your fans will take longer to work> work less. Even in below temps you will not get any coolant codes. Know for summer you must not a must but comes in hand to get a diablo or predator tuner to set the fans a lil bit lower. You can set your fans to kick in around at 200 degrees. So it wont reach that stock 217/219 degree.some set there fans even lower like 195 185 but you will be putting them fans to work 24/7 And also your alternator will be busy since them fans will be running all the time. 200 degrees fans kick in and will lower 7 to 10 degrees and wont reach 219/217 degrees Thanks
