SPE 6.7L POWERSTROKE LOW TEMP, HIGH FLOW THERMOSTAT
Making your truck cool is all in the details and now there’s finally a simple engineered solution for those high fluid temps on your 6.7L Powerstroke that actually works!
DESCRIPTION
Are you seeing uncomfortably high oil temperatures during normal driving or towing? Does your 2017+ Powerstroke seem to have high transmission temperatures?There’s finally an engineered solution for those high fluid temps on your 6.7L Powerstroke!
After extensive testing and consideration of the 6.7L Powerstroke application SPE has engineered a thermostat to combat high fluid temperatures.
The OEM thermostat opens at 194/201°F whereas the SPE Low Temp, High Flow Thermostat opens at 175/180°F. That's a significant decrease in temps as it's a 19-21 degree difference!
The solutions currently available on the market for controlling your coolant, oil, & transmission temperatures* (17+ only) are not cost effective or actual solutions to a simple problem.

VEHICLE COMPATIBILITY
2011-2022 Ford SuperDuty F-250/F-350/F-450/F-550 6.7L Powerstroke
*2017+ Powerstrokes use the primary cooling system to cool the transmission unlike the 2011-2016 which uses the secondary cooling system.
This product shipped very fast, the fitment was flawless and the install is easy, my temperatures have dropped on average 15 to 20° unloaded and 10 to 15° loaded. I tow heavy daily up to 7000 miles a month This products has been a great purchase at a great price.

The Ford 6.7 SPE thermostat is the real deal. I live in South Texas where its hot then a well you know.
This thermostat drops engine temp!
oil temp from 204f to 180f
trans temp from 180f to 160f
Best money you will spend on a 6.7 Ford

Purchase one for my ‘11 F-350. 20 minute install. Waited a while to post until I tested it. Engine is constantly 20 degrees cooler. Hauling Arctic Fox 990, and towing 14’ dump trailer w/ Polaris General 4seat. Best $67 I’ve spent on my truck. Bought another one for my father-in-law‘s 2012 F-350. Same performance. Thanks SPE
John H.
Love your products. Awesome
Emmet T.
Put the thermastat in does exactly what they advertise easy install as well
Spencer C.
I would typically run around 215 to 220 on these hot southern days hauling a trailer and with the high flow low temp thermostat I run between 185 and 195. Feel a lot better with these temperatures.
Kenny R.
Easy install! Already noticed the difference
Bradley W.
Awesome product, very satisfied with it and look forward to buying more product from spe.
jason p.
Seems to have dropped oil temps a lot. Roughly 25 degrees empty. Trans temps are still higher than I’d like. Replaced the factory cooler they’re lower but this trans just inherently runs hot. Added the mishimoto aux add on cooler and we’re now at 195-205 loaded with 10k
Mark L.
Works as described, oem fit and easy install. Temperature is now reading slightly below half on gauges.
Brett Y.
Truck runs a lot cooler and efficient since the install. Works great and love it
Hunter M.
Quick and simple to change out. Instant cooler temps on oil and coolant. Being a 2011 model 6.7 trans temp won’t change but overall happy with SPE’s products
Ronnie R.
Install was real easy. Temp drops as stated. Definitely a must have.
William M.
Just what I ordered great product
Ryan W.
Best coolant upgrade other Thad radiator and coolers. Towing up and down grades this really performed excellent. Trans temps stayed cooler and consistent.

Ferris T.
Dropped me trans and coolant temp by 10+ well worth it
JACKIE B.
Delivery was fast and ahead of time.

Yasiel G.
Very good
Tracy S.
Firm believer in this product! Left the house with over 1300lbs went to Hurricane Utah anyone that’s ever been out there knows when you get west of Denver Colorado it’s some serious hills to pull! First big bull in hot weather was 226 degrees trans was 230 hit the bottom at 65mph dropped to 58mph on a continuous pull rest of the way across interstate 70 and interstate 15 going south never got above 219 on pulls. Last time across there on stock thermostat had to keep backing out because truck was getting hotter than I was comfortable with! Next trip hopefully I will have there transmission proprietary solenoied installed and give it hell to see what it does!

Temperature has really dropped!!! Love it.
Chris L.
Product was exactly as intended. SPE was in contact the entire process and very fast with shipping. Installed within minutes and is working amazing and would definitely recommend to anybody as I’m in Texas with those good high temps while hauling in the summer.
Tim B.
Makes a big difference! Running 20 degrees cooler! Great folks and great products! SPE All the way!
Gavin S.

Peter F.
So works great!
Sidney T.
2021 f450 hauling 2021 keystone avalanche 395bh. From Nashville tn, to Asheville North Carolina. Lots of mountain terrain. Oil temp never exceeded 195, trans temp stayed around 200. The coolant temp stayed around 185. I'm happy with the results.
Ron S.
We had to make a midnight ride to Corsicana, Texas trailering a Tahoe to a friend that needed a vehicle because his had broken down mid trip. We delivered the Tahoe, loaded up a dead Mustang for the return trip. All nighter, 70-75 mph, no loss of mpg loaded or unloaded, and the truck ran amazingly cool. Well worth the few dollars and the thirty minutes installation time. Every 6.7 needs one.
Gary M.
My 2012 defueled when it got to 220 on the water temp. I was in "Mexico" WOT for longer than normal and it was a warm day. So I researched thermostats, read the SPE R&D article and it sound like exactly what I needed. Next time WOT in "Mexico" WOT for extended period it stayed much cooler. I was watchin water and oil temperature on a mini maxx in both cases
seems to be an average offset in temps on my truck by 20 degrees on the water temp in normal driving conditions and the oil temp balances out at 180. you can tell it flows better because if it does heat up from WOT it comes back down very quickly and when it goes up its not even reaching what was normal with the stock t stat
Carlyle M.
Works good have it in multiple trucks
Mellor I.
Saw this on YouTube. Product works as described. Haven’t seen 200° on my transmission temperature since installing the low temp, high flow thermostat. Engine temperature saw a drastic improvement as well. I would definitely recommend this upgrade to anyone with a 6.7 liter powerstroke. Thanks guys.
John P.
Ordered due to needed upper radiator hose because my factory hose was leaking at the top side and I figured since I had that to replace to also put the thermostat on my list after reading the reviews on what an improvement it is in temperature’s and I logged before and after and had a good 15 degree drop in temperature and I would definitely recommend doing this with SPE Upper Radiator hose.
TIMOTHY L.
before install it ,my temp show 1/2way hot, now i install low temp thermostat, it show temp 1/4 hot and it runs cooler when hauling equipments. nice!!!
Cameron W.
Seeing that 20+ degree difference makes me happy! Awesome product guys!
Darren M.
Easy to order on this website fast shipping
Gordon E.
Keeps my truck running cool even when I'm pulling a heavy trailer
ShimShaun T.
Thermostat looks like factory and fits perfectly. Works as described.
Victor C.
Big difference compared to the OEM...
Perfect fitment on my 2022 f250
Dustin A.
If you are going to do the Radiator hose might as well do the thermostat too. Plus it really does keep the temps down a great deal. My Normal easy going temp is now around 178. Big improvement.
Vernon D.
Easy to install with the directions that was provided with the thermostats!!
phillip c.
Super easy to install, definitely made a difference when I pull my trailer up hill, should have done it sooner.
Timothy T.
Totally helped with temps for my engine and transmission! 2017 F350 6.7 liter diesel.
Justin P.
What use to be 200 degree running truck is now in the 150 degree range. A cooler engine is always a happier one! It is funny seeing it only at 1/4 gauge on the dash for temp but I am sure the truck is happier.
Alexander O.
I haven't hauled anything yet to give a real test yet, but driving around town I'm already very happy and would recommend to the next person in a heartbeat!!!!
Christopher M.
Easy install and really makes a difference in the temps!
Dale W.
Excellent product as usual. Can't say enough good things about this company.
Gabriel C.
Works great keeps my temps are 170’s and oil under 200!
isaac p.
Do a lot of hauling, currently hot shotting and this has been great. Have noticed a 15-20 degree difference, wish I had bought this sooner.
William B.
It took about one hour to install.
Jason H.
Thermostat performs better than the factory. Instructions were spot on and made a great addition to the upgraded upper radiator hose kit from SPE.
Christopher O.
Great experience; shipped right away, easy install, and works as advertised!!
Jared P.
Easy to install. My coolant temp stays a solid 176 now daily driving or with a small trailer. I’ll test it hauling heavy and update my review but this is well worth the price if you haul or live where the temps are naturally hot.
James G.
Looks constructed better then the OEM being replaced. Hoping to keep lower temps when pulling camp trailer over passes in the Rocky Mountains!
Tony J.
Just wow what a great product
Andy S.
It truly dropped both engine and trans temp while regular driving and towing! Very well worth the price and the quality is on point as well would definitely buy again worth every penny!
Brandi T.
Reduced temp dramatically while towing.
Matt G.
Easy to install dropped temps by 20 degrees.
Just what I needed
Matthew M.
Works as stated! drained/refilled 4gals fresh coolant out of the primary
Randy H.
it's a great product and a great price. can't wait to see the temperature change while towing my camper.
Jared B.
Easy to install- works great- truck hasn’t gone above 175 coolant temps since installing. I’m a huge fan of SPE products- already have several and saving up for the intake setup. Highly recommend!
Troy M.
Easy installation very good temp control on my 6.7L
Carlyle M.
This Thermostat is what they say it is. Just driving local roads freeway and in traffic.
coolant stays around 172/180
Oil temperature around 180
Product is easy to install and good bang for your buck.
Andrew H.
Super easy install. Haven’t done much driving with it but there is a noticeable difference in the temperatures. Oil and trans temps are down a good 10 - 15 degrees. We will see how it does when I tow our families 17k lb fifth wheel back to PA from California.
Daniel A.
I can tell a big difference in the temperatures on my 2015 6.7 Power stroke with this installed. Way better then factory.
nathan p.
Normal driving transmission temp and oil temp are 20 degrees cooler temps are around 185. Going be to tow my 14000 pound camper this weekend from south Florida to Tennessee I’ll see what the temps do then so far I’m happy.
Philip V.
Out with the old, in with the new. SPE low temp hi flow was added after I put a few led’s in grill of truck & was worried about air flow & cooling. Dropped about 10-15 degrees & keeps oil temp lower as well.
Christopher S.
DID EXACTLY WHAT IT SAID IT WOULD DO. I TOW ALOT AND LIVE IN ARIZONA AND IDAHO SO I ALWAYS SEE HIGH TEMPS AS SOON AS I PULL WEIGHT. PLUS THE HIGH OIL TEMP DEGRADE AND SUPER THIN OUT OIL LONG BEFORE YOU NEED AN OIL CHANGE SO YEAH A,UCH NEEDED ADDITION TO MY AMSOIL REMOTE BYPASS KIT TO ADD MORE OIL AND A BYPASS/SOOT FILTER ALSO. SO YEAH
Christopher M.
Love the product straight forward install nice quality shipping took 2 weeks to receive.
Gabriel D.
This thermostat really does what they claim! Installs in place of the stock part and really does lower the running temps of my 2017 6.7 Powerstroke. Quality and finish is similar if not better than OEM thermostats. Very pleased.
Joseluis L.
Quick and easy temps are around 185 now compared to 205.
Ryan K.
I live in TX its HOT down here i have never seen it above 190 even after 4hi fun in mexico or hauling our loaded cattle trailer honestly if you don't put this in your truck thats just silly. 20min instal and the part is cheap by diesel standards.
Joseluis L.
Easy to install and keeping engine cool.
Justin f.
Super easy to swap. Quality piece too!
Brad P.
Easy install. Perfect fit. Keeps my coolant and oil temps low. Fixed my thermostat issue.
justin c.
Awesome!!!
Walker K.
Works really good. Definitely worth the money. Stock one was chewed up and temps were extremely high. Took me 15 to install. Would recommend this product in a heartbeat to anyone.
Tommy R.
Works amazingly. Oil temp used to be around 215 driving down the road. And about 188 at idle. Now I’m under 200 and around 174 at idle. Haven’t tried it while pulling yet. But I’m sure it’ll be much cooler than before. Definitely recommend.
Shane K.
Parts fit ,looks good, easy install,motor runs cooler,thank you
Donald W.
Great product. 2012 f250 2020 rotating assembly studded oring heads Kc stage 2 turbo. Never runs hotter than 175. Trans stays under 195. And oil temp around 185
Claudette H.
This is the best item for your 6.7 to date!
I have the (EGR,DPF, and catalytic converter deleted) with a H&P mini max plus cold air intake. The low temperature high flow thermostat is by far the best item I’ve put on the engine!! I have not seen the water temp go over 174degree period.
The engine performance is absolutely wonderful now that the temperatures are so low. Whoop whoop .
What else do you have for my 6.7- I’ll purchase it no questions asked.
Thank you!!!!!!!
Jonathan L.
Installation was no more than 30 minutes. Pulled our 12K 5th wheel and a noticeable 10 degree difference. Great work SPE!
Travis N.
F450 weighs 13k empty always towing at elevation in the mountains, couldn't keep coolant temps down as they would spike after pulling any small grade, the SPE thermostat keeps overall temps lower so when it does spike, they are still within the safe operating range of Ford Specs. Rarely see oil temps above 235 with an oversized oil cooler pulling 30k, previously would see 245 routinely. Great purchase and takes twenty minutes to install, most time consuming is draining coolant.
Richard P.
This thermostat reduced my indicated engine temperature by about 15 degrees (F). Subsequently it also reduced the transmission temperature accordingly. I hope that by utilizing the lower temperatures, coupled with proper maintenance, my new 6.7 Power Stroke will last for many years.
2021 F250 Lariat with 6.7 Power Stroke
Rickey K.
Very easy install haven’t got to tow with it yet that’s when I’ll be able to let you know
