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.
Excellent product! Works as described. Temp levels in trans 10-12 degrees cooler on average. Oil temp 12-15 degrees cooler on average. I’m satisfied. Thanks SPE
Tyler T.
Definitely needed a new one! Truck runs at 165-170 and oil temp is at 176 at idle and 187 at 85mph cruising. Definitely recommend
Karl B.
Working like advertised, keeping the engine cooler, and the engine oil cooler. Will help when towing in higher temperatures up ling steep grades and mountains.
Jared F.
My trans temp went down 28* and truck runs way cooler. So stoked.. great product.
Cody C.
Great product. Installed easily and is a huge help towing on the 6.7 PSD
Jacob D.
Works great
Francis T.
Tried and true! Towing a 14k lbs boat on a weekly basis and this just gave me an assurance to not overheat for more boat hauling days to come! Thank you SPE!
Steve W.
Receive item quickly, installed in about 1hr. prior to installation took temp and transmission readouts. After hitting the highway for about an hour, looked at temps for both. Water temp was 7 degrees below and transmission temp was 6 degree's below what I normally saw. Will be traveling with 40ft 5th wheel first week in October. That will be the real test since there are a lot of hills on our route to Oklahoma City, will let you know the outcome. Installation was done to my wife's 2017 Ford F350 dually.
John W.
Unprecedented communication after the sale with shipping information email and text. Easy install and engine and trans temps saw a drastic decrease towing our 45’ LQ horse trailer at interstate speeds

Dropped coolant levels as described. Was hoping it would drop Transmission temps but it did not.
Jerrid G.
I put this thermostat on my 2013 6.7 and loved it so naturally it was my first mod to my new truck and let me say it still doesn’t disappoint. Ford says these engines normal operating temp is 220-240 that’s just crazy to me. I just took a 900 mile trip pulling a horse trailer with 2 horses in it in mid august in Texas where temps get 105 easy outside and oil never got over 205 trans 203 was the high and coolant 187 such a work of art heat is a killer and this bad boy keeps it nice and cool
Jonathan B.
Great packaging, quick shipping. Obviously a thermastat isn't a difficult install. The actual difference is immediate. It does exactly what they list. Works flawlessly and 100% love the purchase. Everyone needs this, if you are reading this... just buy it already!
Brody W.
Product works great. Engine oil remains 13-15 degrees cooler at 188, trans 20-25 degrees cooler at 175, and coolant temp remains around 177-180 no matter how heavy my foot is into the pedal. Excellent product!!
Daniel M.
New low temp thermostat works great! Did exactly what I wanted, lowered coolant and oil temps over 20-25 degrees during normal driving and 10-15 when towing. Fast shipping too.
Shawn F.
Headed to Colorado!
Corey G.
I wish all companies were this responsive and produced great products like these folks.
Look forward to doing business again.
Jordan H.
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.
Anthony A.
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
Scott S.
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.
Perry M.
Engine runs cooler and easy install, total installation 30 minutes.

David A.
Great thermostat my 6.7 powerstroke runs about 15-20 degrees cooler pulling my momentum 397th toy hauler that weighs 18,000. Would highly recommend
Ferris T.
Dropped me trans and coolant temp by 10+ well worth it
JACKIE B.
Delivery was fast and ahead of time.

Brian M.
Exactly what I ordered and works well
ChrisChris H.
Original one had 260k and was time to upgrade the thermostat. I love the cooler temperatures.
jared y.
Works very well! My truck runs somewhere close to 20 degrees cooler than it was with the stock thermostat! I feel it is a very good buy!
Kim S.
Easy to install, the engine 20 degrees cooler.

Stefano B.
It really works!!! Hauling 13000 pounds my temperature wont go above 210 and I live in Colorado
glenn p.
Install when good. Haven’t tested yet.
Marcus M.
Engine runs 30°-40° Cooler. Awesome product.
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.
Super easy install. My truck runs 170 degrees on the coolant and 180 degrees on the oil
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.
